Question 4.
Solve |x – 1| >1 and represent the solution on the number line.
[Exhaustive hints: By definition of modulus function
For x – 1 ≥ 0 or x ≥ 1, |x – 1| > 1
⇔ x – 1 > 1 ⇔ x > 2 ⇔ x ∈ (2, ∞)
For x- 1 < 0 or x < 1, |x – 1| > 1
⇔ – (x – 1) > 1
⇔ x – 1 < -1 (multiplication by -1 reverses the inequality)
⇔ x < 0 ⇔ x ∈ ( -∞, 0)
∴ The solution set is the Union,
(-∞, 0) ∪ (2, ∞) Show this as two disjoint open intervals on the number line, i.e., real line.]
Solution:
|x – 1| > 1
⇒ – 1 > x – 1 > 1

Question 7.
The length of one side of a parallelogram is 1 cm. shorter than that of its adjacent side. If its perimeter is at least 26 c.m., find the minimum possible lengths of its sides.
Solution:
Let the longer side = x cm
∴ The smaller side = (x – 1) cm
Perimeter = 2(x + (x – 1)) = 4x – 2 cm
According to the question
4x – 2 ≥ 26
⇒ 4x ≥ 28
⇒ x > 7
The minimum value of x = 7.
∴ The minimum length of the sides is 7cm and 6 cm.

Question 8.
The length of the largest side of a quadrilateral is three times that of its smallest side. Out of the other two sides, the length of one is twice that of the smallest and the other is 1 cm. longer than the smallest. If the perimeter of the quadrilateral is at most 36 c.m., then find the maximum possible lengths of its sides.
Solution:
Let the smallest side = x cm.
Largest side = 3 times x = 3x cm.
The other two sides are 2x cm and x + 1 cm.
⇒ The perimeter = x + 3x + 2x + x + 1
= 7x + 1 cm
According to the question:
7x + 1 ≤ 36
⇒ 7x ≤ 35
⇒ x ≤ 5
Maximum value of x = 5
∴ The maximum possible length of sides are x = 5 cm, 3x = 15 cm, 2x = 10 cm, and x + 1 = 6 cm.

Question 9.
Find all pairs of consecutive odd numbers each greater than 20, such that their sum is less than 60.
Solution:
Let two consecutive odd numbers are
2n – 1 and 2n + 1
Now 2n – 1 > 20 and 2n + 1 > 20
But their sum = 2n – 1 + 2n + 1
= 4n < 60
⇒ n < 15
for n = 14 two numbers are 27, 29
for n = 13 two numbers are 25, 27
for n = 12 two numbers are 23, 25
for n = 11 two numbers are 21, 23
∴ All pairs are 21, 23; 23, 25; 25, 27 and 27, 29

Question 10.
Find all pairs of even numbers each less than 35, such that their sum is at least 50.
Solution:
Let two even numbers be x and y.
According to the question
x < 35, y < 35 and x + y ≥ 50
⇒ x ≤ 34, y ≤ 34 and x + y ≥ 50
⇒ x + y ≤ 70, x + y ≥ 50
⇒ 50 ≤ x + y ≤ 70
If x + y = 50 the numbers are {34, 16}, {32, 18}, {30, 20}, {28, 22}, {26, 24}
If x + y = 52 the numbers are {34, 18}, {32, 20}, {30, 22}, {28, 24}, {26, 26}

Question 16.
2 (bc cos A + ca cos B + ab cos C) = a2 + b2 + c2
Solution:
2 (bc cos A + ca cos B + ab cos C) = a2 + b2 + c2
\(=2\left(b c \times \frac{\left(b^2+c^2-a^2\right)}{2 b c}+c a \times \frac{c^2+a^2-b^2}{2 c a}\right.\) \(\left.+a b \times \frac{a^2+b^2-c^2}{2 a b}\right)\)
= b2 + c2 – a2 + c2 + a2 – b2 + a2 + b2– c2
= a2 + b2 + c2

Question 17.
a (b2 + c2) cos A + b (c2 + a2) cos B + c(a2 + b2) cos C = 3 abc.
Solution:
a (b2 + c2) cos A + b (c2 + a2) cos B + c(a2 + b2) cos C
= ab2 cos A + ac2 cos A + bc2 cos B + ba2 cos B + ca2 cos C + cb2 cos C
= ab2 cos A + ba2 cos B + ac2 cos A + ca2 cos C + bc2 cos B + cb2 cos C
= ab (b cos A + a cos B) + ac (c cos A + a cos C) bc (c cos B + b cos C)
= abc = abc + abc = 3abc

Question 18.
a3 cos (B – C) + b3 cos (C – A) + c3 cos (A – B) = 3 abc
Solution:
1st term of L.H.S. = a3 cos (B – C)
= a2 a cos (B – C)
= a2 . 2R sin A cos (B – C)
= 2a2R sin (B + C) cos (B- C)
= a2R [sin (B + C + B – C) + sin (B + C – B + C)]
= a2 R (sin 2B + sin 2C)
= a2R [2 sin B cos B + 2 sin C cos C]
= a2 [2R sin B cos B + 2R sin C cos C]
= a2 (b cos B + c cos C)
Similarly, 2nd term
= b2 (c cos C + a cos A) and
3rd term = c2 (a cos A + b cos B)
∴ L.H.S.= a2b cos B+a2c cos C+b2c cos C + b2a cos A + c2a cos A + c2b cos B
= ab (a cos B + b cos A) + bc (b cos C + c cos B) + ca (c cos A + a cos C)
= abc + bca + cab = 3abc = R.H.S.

Solution:
CHSE Odisha Class 11 Math Solutions Chapter 4 Trigonometric Functions Ex 4(d) 34
or, cos C = 1/2 or, ∠C = 60°

Question 28.
If a = 2b and A = 3B, find the measures of the angles of the triangle.
Solution:
If a = 2b and A = 3B, we have \(\frac{a}{b}\) = 2
or, \(\frac{\sin A}{\sin B}\) = 2
or, sin A = 2 sin B         …..(1)
Also  sin A = sin 3B (as a = 3B)    …..(2)
∴ From (1) and (2), we have
2 sin B = sin 3B = 3 sin B – 4 sin3 B
or, 4 sin3 B – sin B = 0
or, sin B(4 sin2 B – 1) = 0
or, sin B = 0, 4 sin2 B = 1
Now sin B = 0 ⇒ B = 0 (Impossible)
∴ sin2 B = \(\frac{1}{2}\) or, sin B = ± \(\frac{1}{2}\)
If sin B = \(\frac{1}{2}\) then ∠B = 30°
∴ A = 3B = 3 x 30° = 90°
∠C = 60°

Question 29.
If a4 + b4 + c4 = 2c2 (A2 + b2), prove that m∠ACB = 45° or 135°.
Solution:
a4 + b4 + c4 = 2c2 (a2 + b2)
or, a4 + b4 + c4 + 2a2b2 – 2b2c2 – 2c2a2 = 2a2b2
or, (a2 + b2 – c2)2 = 2a2b2
or, a2 + b2 – c2 = ± √2 ab
or, \(\frac{a^2+b^2-c^2}{2 a b}=\pm \frac{1}{\sqrt{2}}\)
or, cos C = ± \(\frac{1}{\sqrt{2}}\)
∴ ∠C = 45° or 135°.

Question 31.
if cos B = \(\frac{\sin A}{2 \sin C}\), prove that the triangle is isosceles.
Solution:
cos B = \(\frac{\sin A}{2 \sin C}\)
⇒ \(\frac{c^2+a^2-b^2}{2 c a}=\frac{a}{2 c}\) ⇒ c2 + a2 – b2 = a2
or, c2 = b2 or, c = b
∴ The triangle is isosceles.

Question 32.
If a tan A + b tan B = (a + b)tan \(\frac{1}{2}\) (A + B) prove that the triangle is isosceles.

Question 33.
If (cos A + 2 cos C) : (cos A + 2 cos B) = sin B : sin C prove that the triangles are either isosceles or right-angled.
Solution:
\(\frac{\cos A+2 \cos C}{\cos A+2 \cos B}=\frac{\sin B}{\sin C}\)
⇒ cos A sin C = cos A sin B + 2 cos B sin B
⇒ cos A (sin B – sin C) + (sin 2B – sin 2c) = 0
⇒ cos A (sin B – sin C) + 2 cos (B + C) sin (B – C) = 0
⇒ cos A (sin B – sin C) – 2 cos A sin (B – C) = 0
(∴ cos (B + C) = cos (π – A) = – cos A)
⇒ cos A = 0 or sin B – sin C – 2 sin (B – C) = 0
cos A = 0 ⇒ A = 90°
i.e. the triangle is right-angled. sin B sin C – 2 sin (B – C) = 0
CHSE Odisha Class 11 Math Solutions Chapter 4 Trigonometric Functions Ex 4(d) 39

Question 34.
If cos A = sin B – cos C, prove that the triangle is right-angled.

or, 2C = π
or, C = \(\frac{\pi}{2}\)

Question 35.
If a2, b2, c be in A.P., prove that cot A, cot B, cot C are also in A.P.
Solution:
If a2, b2, c be in A.P.
then b2 – a2 = c2 – b2
or, 2b2 = c2 + a2
or, \(b^2=\frac{c^2+a^2}{2}\)
or, 2b2 = c2 + a2 …..(1)
We have to prove that cot A, cot B, cot C are in A.P.
i.e. to prove cot B – cot A = cot C – cot B
i.e. 2 Cot B = cot C + cot A
∴ R.H.S. = cot C + cot A

Question 36.
If sin A: sin C = sin (A – B) : sin (B – C) prove that a2, b2, c2 are in A.P.
Solution:
\(\frac{\sin A}{\sin C}=\frac{\sin (A-B)}{\sin (B-C)}\)
or, sin A sin (B – C) = sin C sin (A – B)
or, sin (B + C) sin (B – C) = sin (A + B) sin (A – B)
or, sin2 B – sin2 C = sin2 A – sin2 B
or, 2 sin2 B = sin2 C + sin2 A
or, \(2 \frac{b^2}{4 \mathrm{R}^2}=\frac{c^2}{4 \mathrm{R}^2}+\frac{a^2}{4 \mathrm{R}^2}\)
or, 2b2 = c2 + a2
or, b2 – a2 = c2 – b2
∴ a2, b2, c2 are in A.P

Question 2.
What can you say about sets A and B if
(i) A ∪ B= Φ
(ii) A Δ B = Φ
(iii) A \ B = Φ
(iv) A \ B = A
(v) A ∩ B= U, Where U is the Universal set, A \ B = U?
Solution:
(i) if A ∪ B = Φ then A = Φ =B
(ii) A Δ B = Φ ⇒ A = B
(iii) A – B = Φ ⇒ A ⊆ B
(iv) A – B = A ⇒ B = Φ
(v) A ∩ B = U ⇒ A = B = U
(vi) A – B = U ⇒ A = U and B = Φ

Question 3.
Are differences and symmetric commutative? Give reason.
Solution:
The difference of the two sets is not commutative but the symmetric of the two sets is commutative.
Reason:
Let x ∈ A – B ⇔ x ∈ A ∧ x ∉ B
≠ x ∈ B ∧ x ∉ A ⇔ x ∈ b – A
A- B ≠ B – A
But if y ∈ A Δ ⇔ y ∈ (A-B) ∪ (B – A)
⇒ y ∈ (B – A) ∪ (A – B) ⇔ y ∈ B Δ A
∴ A Δ B = B Δ A.

Question 4.
If B ⊂ C, prove that A/B = A/C. Is this result true when a difference is replaced by a symmetric difference? Give reason.
Solution:
If B ⊂ C, then x ∈ A ⇒ x ∈ C
Now x ∈ A – C ⇔ x: x ∈ A ∧ x ∉ C
⇔ {x: x ∈ A ∧ x ∉ B}
⇔ {x: x ∈ A – C}
∴ A – C = A – B
but, A Δ B ≠ A Δ C.

Question 5.
Prove the following :
(i) (A\B)\C = (A\C)\B = A\(B ∪ C)
(ii) A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∪ B)
(iii) A Δ (B Δ C) = (A Δ B) Δ C
(iv) A ⊂ B ⇔ B’ ⊂ A’ A ⇔ A’ ∪ B = U
⇔ B’ ∩ A = Φ, where U is the universal set.
(v) A ∪ B = U and A ∩ B = Φ
⇒ B = A’
(iv) A ∪ B = A for all A ⇒ B = Φ
Solution:

(i) Let x ∈ (A – B) – C    ……(1)
⇔ x ∈ A- B ∧ x ∉ C
⇔ (x ∈ A ∧ x ∉ B) ∧ x ∉ C   ……(2)
⇔ (x ∈ A ∧ x ∉ C) ∧ x ∉ B
⇔ x ∈ A – C ∧ x ∉ B
⇔ x ∈ (A – C) – B   ……(3)
∴ from (2), we have
x ∈ A ∧ ∉ B ∧ x ∉ C
⇔ x ∈ A ∧ (x ∉ B ∧ x ∉ C)
⇔ x ∈ A ∧ x ∉ B ∪ C
[∴ ~ (p ∨ q) = ~ p ∧ ~ q]
⇔ x ∈ A – (B ∪ C)   …….(4)
∴ From (1), (3), and (4), we have
(A – B) – C = (A – C)-B = A – (B ∪ C)

(ii) Let x ∈ A ∩ (B ∪ C)
⇔ x ∈ A ∧ x ∈ B Δ C
⇔ x ∈ A ∧ (x ∈ B – C ∨ x ∉ C – B)
⇔ x ∈ A ∧ (x ∈ B ∧ x ∉ C ∨ x ∈ C ∧ x ∉ B)
⇔ x ∈ A ∧ (x ∈ B ∧ x ∈ A ∧ C) ∨ x ∈ A ∧ (x ∈ B ∧ x ∈ B ∧ x ∈ A ∧ x ∉ B)
⇔ (x ∈ A ∩ B ∧ x ∉ A ∩ C) ∨ (x ∈ A ∩ C  ∨ x ∉ A ∩ B)
⇔ x ∈ (A ∩ B) – (A ∩ C) ∨ x ∈ (A ∩ C) – (A ∩ B)
⇔ x ∈ (A ∩ B) Δ (A ∩ C)   ……(2)
∴ From (1) and (2), we have
A ∩ (B Δ C) = (A ∩ B) Δ (A ∩ C)

(iii) A Δ (B Δ C)
= A ∪ (B Δ C)- A ∩ (B Δ C)
= A Δ (B ∪ C)- A Δ (B ∩ C)
[ ∴ A ∪ (B Δ C) = A Δ (B ∪ C)]
and A n (B Δ C) = A Δ (B ∩ C)
= (A Δ B) ∪ C- (A Δ B) ∩ C
[∴ A Δ (B ∪ C) = (A Δ B) ∪ C and A Δ (B ∩ C) = (A Δ B) ∩ C
= (A Δ B) Δ C
∴ A Δ (B Δ C)= (A Δ B) Δ C
(Proved)

(iv) If A ⊂ B then x ∈ B’ or ⇒ x ∉ B
⇒ x ∉ B ⇒ x ∈ A’ (∴ A ⊂ B)
∴ B’ ⊂ A’
Again, let y ∈ A ⇒ y ∉ A’ ⇒ y ∈ B’
( B’ ⊂ A’)
⇒ y ∈ B ∴ A ⊂ B
∴ A ⊂ B ⇔ B’ ⊂ A’
∴ Again as A ⊂ B, we have
U = A ∪ B = B = U, where U is the universal set of A and B.
∴ A’= B – A ⇒ A’ ∪ B
= (B – A) ∪ B = B = U
∴ A ⊂ B ⇒ A’ ∪ B = U
Again A’ ∪ B = U
⇒ A ∩ (A’ ∪ B) = A ∩ U = A
⇒ (A ∩ A’) ∪ (A ∩ B) = A
⇒ Φ ∪ (A ∩ B) = A
⇒ A ∩ B = A ⇒ A ⊂ B
Lastly, B’ = U’ = Φ
∴ B’ ∩ A = Φ

(v) Let A ∪ B = U and A ∩ B = Φ
∴ Let x ∈ B ⇔ x ∉ B’ ⇔ x ∉ U – B
⇔ x ∉ A ⇔ x ∉ A’

(vi) As A ∪ B = A for all A
we have B ⊂ A for all A
∴ B ⊂ A even for A = Φ Thus B = Φ

Question 6.

Solution:
(i) A ∪ B = B ∪ A
Let x ∈ A ∪ B ⇔ x ∈ A ∨ x ∈ B
⇔ x ∈ B ∨ x ∈ B ⇔ x ∈ B ∪ A

(ii) A ∩ B = B ∩ A
Let x ∈ A ∩ B ⇔ x ∈ A ∧ x ∈ B
∴ A ∩ B = B ∩ A

(iii) A ∩ (B ∪ C)
= (A ∩ B) ∪ (A ∩ C)
Let x ∈ A ∩ (B ∪ C)
⇔ x ∈ A ∧ x ∈ A ∪ C
⇔ x ∈ A ∧ (x ∈ A ∨ x ∈ C)
⇔ (x ∈ A ∩ B ∨ x ∈ A ∩ C)
⇔ (x ∈ A ∧ x ∈ B) ∨ (x ∈ A ∧ x ∈C)
⇔ x ∈ (A ∩ B) ∪ (A ∩ C)
∴ A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)

⇔ x ∈ A  ∧ x ∉(B1 ∪ B2 ∪….∪ Bn )
⇔ x ∈ A  ∧ (x ∉ B1 ∧ x ∉ B2 ∧…..∧ x ∉ Bn )
⇔ (x ∈ A  ∧ x ∉ B1 ) ∧ (x ∈ A ∧ x ∉ B2 ) ∧….∧ (x ∈ A  ∧ x ∉ Bn )
⇔ x ∈ A – B1 ∧ x ∈ A – B2 ∧……..∧ x ∈ A – Bn
⇔ x ∈ (A – B1 ) ∩ (A – Bi ) ∩…..∩ (A – Bn )
⇔ \(x \in \bigcap_{i=1}^n\left(\mathrm{~A}-\mathrm{B}_{\mathrm{i}}\right)\)
∴ \(\mathrm{A}-\cup_{i=1}^n \mathrm{~B}_{\mathrm{i}}=\bigcap_{i=1}^n\left(\mathrm{~A}-\mathrm{B}_{\mathrm{i}}\right)\)

(ii) ∴ \(\mathbf{A}-\bigcap_{i=1}^n \mathbf{B}_i=\bigcup_{i=1}^n\left(\mathbf{A}-\mathbf{B}_i\right)\)
Solution:
Let x ∈ \(A-\bigcap_{i=1}^n B_i\)
⇔ x ∈ A ∧ x ∈ \(\bigcap_{i=1}^n \mathrm{~B}_{\mathrm{i}}\)
⇔ x ∈ A ∧ x ∉ (B1 ∩ B2 ∩….∩ Bn )
⇔ x ∈ A ∧ (x ∉ B1 ∨ x ∉ B2 ∨….∨ x ∉ Bn )
⇔ (x ∈ A ∧ x ∉ B1 ) ∨ (x ∈ A ∧ x ∉ B2 ) ∨….∨ (x ∈ A ∧ x ∉ Bn )
⇔ x ∈ A – B1 ∨ x ∈ A – B2 ∨……..∨ x ∈ A – Bn
⇔ x ∈ (A – B1 ) ∪ (A – B2 )……(A – Bn )
⇔ x ∈ \(\cup_{i=1}^n\left(\mathrm{~A}-\mathrm{B}_{\mathrm{i}}\right)\)

|A ∪ B| =|A| + |B| – |A ∩ B|)
= |A| + |B ∪ C| – | A ∩ (B ∪ C)|
= |A| + |B| + |C| – |B ∩ C| – |(A ∩ B) ∪ (A ∩ C)|

Solution:
Given |X ∪ Y| = 20
|X| = 10
|Y| = 15
We know that |X ∪ Y|
= |X| + |Y| – |X ∩ Y|
⇒ 20 = 10 + 15 – |X ∩ Y|
⇒ |X ∩ Y| = 25 -20 = 5
∴ X ∩ Y has 5 elements.

|H ∪ E| = 450, |H| = 300,
|E| = 250
We want to find 1 H ∩ E
|H ∩ E| = |H| + |E|-  |H ∪ E|
= 300 + 250 – 450 = 100
∴ 100 people can speak both Hindi and English.

Question 11.
In a group of people,37 like coffee, 52 like tea and each person in the group likes at least one of the two drinks. 19 people like both tea and
coffee, how many people are in the group?
Solution:
Let T = The set of persons who like Tea. ,
C = The set of persons who like coffee According to the question
|C| = 37, |T| = 52 and |T ∩ C| = 19
Total number of persons in the group
= |T ∩ C| = |T| + |C| – |T ∩ C|
= 37 + 52 – 19 = 70

Question 12.
In a class of 35 students, each student likes to play either cricket or hockey. 24 students like to play cricket and 5 students like to play both games; how many students play hockey?
Solution:
Let C = Set of students like to play cricket
H = The set of students like to play Hockey.
According to the question
|C ∪ H| = 35
|C| = 24, |C ∩ H| = 5
Now |C ∪ H| = |C| + |H| – |C ∩ H|
⇒ 35 = 24 + |H| – 5
⇒ |H| = 16
16 students like to play Hockey.

Question 13.
In a class of 400 students, 100 were listed as taking apple juice, 150 as taking orange juice and 75 were listed as taking both apple as well as orange juice. Find how many students were taking neither apple juice or orange juice.
Solution:
Let A = The set of students take apple juice
O = The set of students take orange juice
According to the question
|A| = 100, |O| = 150 and
|A ∩ O| = 75
∴ Number of students take at least one of the juice = |A ∪ O|
= |A| + |O| – |A ∩ O|
= 100 + 150 – 75 = 175
Total number of students
= |U| = 400
Number of students taking neither of these juice
= |U| – |A ∪ O|
= 400 – 175 = 225

Long Questions With Answers

Question 1.
Write the Steps in the Formulation of a Client’s Problem.
Answer:
Clinical formulation refers to formulating the problem of the client in the therapeutic model being used for the treatment. The clinical formulation has the following advantages:

Understanding of the problem :
The therapist is able to understand the full implications of the distress being experienced by the client.

Identification of the areas to be targetted for treatment in psychotherapy:
The theoretical formulation clearly identifies the problem areas to be targeted for. therapy. Thus, if a client seeks help for their inability to hold a job and reports an inability to face superiors, the clinical formulation in behaviour therapy would state it as a lack of assertiveness skills and anxiety. The target areas have thus been identified as the inability to assert oneself and heightened anxiety.

Choice of techniques for treatment:
The choice of techniques for treatment depends on the therapeutic system in which the therapist has been trained. However, even within this broad domain, the choice of techniques, timing of the techniques, and expectations of the outcome of the therapy depend upon the clinical formulation. The clinical formulation is an ongoing process. Formulations may require reformulations as clinical insights are gained in the process of therapy. Usually, the first one or two sessions yield enough clinical material for the initial clinical formulation. It is not advisable to start psychotherapy without a clinical formulation.

Question 2.
What is psychodynamic therapy?
Answer:
Psychodynamic therapy pioneered by Sigmund Freud is the oldest form of psychotherapy. His close collaborator Carl Jung modified it to what came to be known as analytical psychotherapy. Subsequently, Freud’s successors, known as Neo-Freudians, established their own versions of classical psychodynamic therapy. Broadly, psychodynamic therapy has conceptualised the structure of the psyche, the dynamics between different components of the psyche, and the source of psychological distress.

You have already studied these concepts in the chapters, on Self and Personality, and Psychological Disorders. The method of treatment, steps in the treatment, nature of the therapeutic relationship, and the expected outcome from the psychodynamic therapy are explained below.

Methods of Eliciting the Nature of Intrapsychic Conflict:
Since the psychoanalytic approach views intrapsychic conflicts to be the cause of the psychological disorder, the first step in the treatment is to elicit this intrapsychic conflict. Psychoanalysis has invented free association and dream interpretation as two important methods for eliciting intrapsychic conflicts. The free association method is the main method for understanding the client’s problems.

Once a therapeutic relationship is established, and the client feels comfortable, the therapist makes her/him lie down on the couch, close her/his eyes and asks her/him to speak whatever comes to mind without censoring it in any way. The client is encouraged to freely associate one thought with another, and this method is called the method of free association. The censoring superego and the watchful ego are kept in abeyance as the client speaks whatever comes to mind in an atmosphere that is relaxed and trusting.

As the therapist does not interrupt, the free flow of ideas, desires and conflicts of the unconscious, which had been suppressed by the ego, emerges into the conscious mind. This free uncensored verbal narrative of the client is a window into the client’s unconscious to which the therapist gains access. Along with this technique, the client is asked to write down her/his dreams upon waking up.

Psychoanalysts look upon dreams as symbols of the unfulfilled desires present in the unconscious. The images of the dreams are symbols which signify intrapsychic forces. Dreams use symbols because they are indirect expressions and hence would not alert the ego. if the unfulfilled desires are expressed directly, the ever-vigilant ego would suppress them and that would leads to anxiety. These symbols are interpreted according to an accepted convention of translation as indicators of unfulfilled desires and conflicts.

Modality of Treatment:
Transference and Interpretation:
Transference and Interpretation are the means of treating the patient. As the unconscious forces are brought into the conscious realm through free association and dream interpretation described above, the client starts identifying the therapist with the authority figures of the past, usually childhood. The therapist may be seen as the punitive father, or as the negligent mother.

The therapist maintains a non-judgmental yet permissive attitude and allows! the client to continue with this process of emotional identification. This is the process of transference. The therapist encourages this process because it helps her/him in understanding the unconscious conflicts of the client. The client acts out her/his frustrations, anger, fear and depression that s/he harboured towards that person in the past, but could. not express at that time.

The therapist becomes a substitute for that person in the present. This stage is called transference neurosis. A full-blown transference neurosis is helpful in making the therapist aware of the nature of intrapsychic conflicts suffered by the client. There is the positive transference in which the client idolises, or falls in love with the therapist, and seeks the therapist’s approval.

Negative transference:
Negative transference is present when the client has feelings of hostility, anger, and resentment towards the therapist. The process of transference is met with resistance. Since the process of transference exposes the unconscious wishes and conflicts, thereby increasing the distress levels, the client resists transference. Due to resistance, the client opposes the progress of therapy in order to protect herself/himself from the recall of painful unconscious memories. Resistance can be conscious or unconscious.

Conscious resistance is present when the client deliberately hides some information. Unconscious resistance is assumed to be present when the client becomes silent during the therapy session, recalls trivial details without recalling the emotional ones, misses appointments, and comes late for therapy sessions. The therapist overcomes the resistance by repeatedly confronting the patient about it and by uncovering emotions such as anxiety, fear, or shame, which are causing the resistance. Interpretation is the fundamental mechanism by which change is effected.

Confrontation and clarification:
Confrontation and clarification are the two analytical techniques of interpretation. In a confrontation, the therapist points out to the client an aspect of her/his psyche that must be faced by the client. Clarification is the process by which the therapist brings a vague or confusing event into sharp focus. This is done by separating and highlighting important details about the event from unimportant ones. Interpretation is a more subtle process. It is considered to be the pinnacle of psychoanalysis.

The therapist uses the unconscious material that has been uncovered in the process of free association, dream interpretation, transference and resistance to make the client aware of the psychic contents and conflicts which have led to the occurrence of certain events, symptoms and conflicts. Interpretation can focus on intrapsychic conflicts or on deprivations suffered in childhood.

The repeated process of using confrontation, clarification, and interpretation is known as working through. Working through helps the patient to understand herself/ himself and the source of the problem and to integrate the uncovered material into her/his ego. The outcome of working through is insight. Insight is not a sudden event but a gradual process wherein the unconscious memories are repeatedly integrated into conscious awareness. These unconscious events and memories are re-experienced in transference and are worked through.

As this process continues, the client starts to understand herself/himself better at an intellectual and emotional level, and gains insight into her/his Conflicts and problems. Intellectual understanding is intellectual insight. -The emotional understanding, acceptance of one’s irrational reaction to the unpleasant events of the past, and the willingness to change emotionally as well as making the change is emotional insight.

Insight is the end point of therapy as the client has gained a new understanding of herself/himself. In turn, the conflicts of the past, defence mechanisms and physical symptoms are no longer present and the client becomes a psychologically healthy person. Psychoanalysis is terminated at this stage.

Duration of Treatment:
Psychoanalysis lasts for several years, with one-hour sessions for 4-5 days per week. It is an intense treatment. There are three stages in the treatment. Stage one is the initial phase. The client becomes familiar with the routines, establishes a therapeutic relationship with the analyst and gets some relief with the process of recollecting the superficial materials from the consciousness about the past and present troublesome events.

Stage two is the middle phase, which is a long process. It is characterised by transference, resistance on the part of the client and confrontation and clarification, i.e. working through on the therapist’s part. All these processes finally, lead to insight. The third phase is the termination phase wherein the relationship with the analyst is dissolved and the client prepares to leave the therapy.

Question 3.
What is Behaviour Therapy and how it is used in patients?
Answer:
Behaviour therapies postulate that psychological distress arises because of faulty behaviour patterns or thought patterns. It is, therefore, focused oh the behaviour and thoughts of the client in die present. The past is relevant only to the extent of understanding the origins of faulty behaviour and thought patterns. The past is not activated or relived. Only the faulty patterns are corrected in the present.

The clinical application of learning theory principles constitutes behaviour therapy. Behaviour therapy consists of a large set of specific techniques and interventions. It is not a unified theory, which is applied irrespective of the clinical diagnosis or the symptoms present. The symptoms of the client and the clinical diagnosis are the guiding factors in the selection of the specific techniques or interventions to be applied.

Treatment of phobias or excessive and crippling fears would require the use of one set of techniques while that of anger outbursts would require another. A depressed client would be treated differently from a client who is anxious. The foundation of behaviour therapy is on formulating dysfunctional or faulty behaviours, the factors which reinforce and maintain these behaviours and devising methods by which they can be changed.

Method of Treatment:
The client with psychological distress or with physical symptoms, which cannot be attributed to physical disease, is interviewed with a view to analysing her/his behaviour patterns. Behavioural analysis is conducted to find malfunctioning behaviours, the antecedents of faulty learning and the factors that maintain or continue faulty learning. Malfunctioning behaviours are those behaviours which cause distress to the client.

Antecedent factors are those causes which predispose the person to indulge in that behaviour. Maintaining factors are those factors which lead to the persistence of faulty behaviour. An example would be a young person who has acquired the malfunctioning behaviour of smoking and seeks help to get rid of smoking. Behavioural analysis conducted by interviewing the client and the family members reveals that the person started smoking when he was preparing for the annual examination.

He had reported relief from anxiety upon smoking. Thus, an anxiety-provoking situation becomes the causative or antecedent factor. The feeling of relief becomes the maintaining factor for him to continue smoking. The client has acquired the operant response of smoking, which is maintained by the reinforcing value of relief from anxiety. Once the faulty behaviours which cause distress, have been identified, a treatment package is chosen.

The aim of the treatment is to extinguish or eliminate faulty behaviours and substitute them with adaptive behaviour patterns. The therapist does this by establishing an|ecedent operations and consequent operations. Antecedent operations control behaviour by changing something that precedes such behaviour. The change can be done by increasing or decreasing the reinforcing value of a particular consequence. This is called establishing operation.

For example, if a child gives trouble eating dinner, an establishing operation would be to decrease the quantity of food served at tea time. This would increase the hunger at dinner and thereby increase the reinforcing value of food at dinner. Praising the child when she/he eats properly tends to encourage this behaviour. The antecedent operation is the reduction of food at tea time and the consequent operation is praising the child for eating dinner. It establishes the response to eating dinner.

Question 4.
What is behavioural technique?
Answer:
Behavioural Techniques:
A range of techniques is available for changing behaviour. The principles of these techniques are to reduce the arousal level of the client, alter behaviour through classical conditioning or operant conditioning with different contingencies of reinforcements, as well as to use vicarious learning procedures, if necessary. Negative reinforcement and aversive conditioning are the two major techniques of behaviour modification.

As you have already studied in Class XI, Negative reinforcement refers to following an undesired response with an outcome that is painful or not liked. For example, the teacher reprimands a child who shouts in class. This is negative reinforcement.

Aversive conditioning:
Aversive conditioning refers to the repeated association of undesired responses with an aversive consequence. For example, an alcoholic is given a mild electric shock and asked to smell the alcohol. With repeated pairings, the smell of alcohol is aversive as the pain of the shock is associated with it and the person will give up alcohol. If adaptive behaviour occurs rarely, positive reinforcement is given to increase the deficit.

For example, if a child does not do homework regularly, positive reinforcement may be used by the child’s mother by preparing the child’s favourite dish whenever s/he does homework at the appointed time. The positive reinforcement of food will increase the behaviour of doing homework at the appointed time. Persons with behavioural problems can be given a token as a reward every time a wanted behaviour occurs.

The tokens are collected and exchanged for a reward such as an outing for the patient or a treat for the child. This is known as the token economy. Unwanted behaviour can be reduced and wanted behaviour can be increased simultaneously through differential reinforcement. Positive reinforcement for the wanted is one such method. The other method is to positively reinforce the wanted behaviour and ignore the unwanted behaviour.

The latter method is less painful and equally effective. For example, let us consider the case of a girl who sulks and cries when she is not taken to the cinema when she asks. The parent is instructed to take her to the cinema if she does not cry and sulk but not to take her if she does. Further, the parent is instructed to ignore the girl when she cries and sulks.

The wanted behaviour of politely asking to be taken to the cinema increases and the unwanted behaviour of crying and sulking decreases. You read about phobias or irrational fears in the previous chapter. Systematic desensitisation is a technique introduced by Wolpe for treating phobias or irrational fears. The client is interviewed to elicit fear-providing situations and together with the client, the therapist prepares a hierarchy of anxiety-provoking stimuli with the least anxiety-provoking stimuli at the bottom of the hierarchy.

The therapist relaxes the client and asks the client to think about the least anxiety-provoking situation. It gives details of relaxation procedures. The client is asked to stop thinking of the fearful situation if the slightest tension is felt. Over sessions, the client is able to imagine more severe fear-provoking situations while maintaining relaxation. The client gets systematically desensitised to the fear.

The principle of reciprocal inhibition operates here:
This principle states that the presence of two mutually opposing forces at the same time inhibits the weaker force. Thus, the relaxation response is first built up and a mildly anxiety-provoking scene is imagined, and the anxiety is overcome by the relaxation. The client is able to tolerate progressively greater levels of anxiety because of her/his relaxed state. Modelling is the procedure wherein the client learns to behave in a certain way by observing the behaviour of a role model or the therapist who initially acts as the role model. Vicarious learning, i.e. learning by observing others, is used through a.

Question 5.
What is Cognitive Therapy?
Answer:
Cognitive therapies locate the cause of psychological distress in irrational thoughts and beliefs. Albert Ellis formulated Rational Emotive Therapy (RET). The central thesis of this therapy is that irrational beliefs mediate between antecedent events and their consequences. The first step in RET is the antecedent belief- consequence {ABC) analysis. Antecedent events, which caused psychological distress, are noted.

The client is also interviewed to find the irrational beliefs, which are distorting the present reality. Irrational beliefs may not be supported by empirical evidence; e in the environment. These beliefs are characterised by thoughts with ‘musts’ and ‘shoulds’, i.e. things ‘must’ and ‘should’ be in a particular manner. Examples of irrational beliefs are, “One should be loved by everybody all the time”, “Human misery is caused by external events over which one does not have any control”, etc.

This distorted perception of the antecedent event due to the irrational belief leads to the consequence, i.e. negative emotions and behaviours. Irrational beliefs are assessed through questionnaires and interviews. In the process of RET, the irrational beliefs are refuted by the therapist through a process of non-directive questioning. The nature of questioning is gentle, without probing or being directive.

The questions make the client think deeper into her/his assumptions about life and problems. Gradually the client is able to change the irrational beliefs by making a change in her/his philosophy about life. The rational belief system replaces the irrational belief system and there is a reduction in psychological distress. Another cognitive therapy is that of Aaron Beck.

His theory of psychological distress characterised by anxiety or depression states that childhood experiences provided by the family and society develop core schemas or systems, which include beliefs and action patterns in the individual. Thus, a client, who was neglected by the parents as a child, develops the core schema of “I am not wanted”. During the course of their life, a critical incident occurs in her/his life. She/he is publicly ridiculed by the teacher in school.

This critical incident triggers the core schema of “I am not wanted” leading to the development of negative automatic thoughts. Negative thoughts are persistent irrational thoughts such as “nobody loves me’’, “I am ugly”, “I am stupid”, “I will not succeed”, etc. Such negative automatic thoughts are characterised by cognitive distortions. Cognitive distortions are ways of thinking which are general in nature but which distort reality in a negative manner.

These patterns of thought are called dysfunctional cognitive structures. They lead to errors of cognition about social reality. Repeated occurrences of these thoughts leads to the development of feelings of anxiety and depression. The therapist uses questioning, which is a gentle, non-threatening disputation of the client’s beliefs and thoughts. Examples of such questions would be, “Why should everyone love you ?”, “What does it mean to you to succeed?”, etc.

The questions make the client think in a direction opposite to that of the negative automatic thoughts whereby s/he gains insight into the nature of her/ his dysfunctional schemas, and is able to alter her/his cognitive structures. The aim of the therapy is to achieve this cognitive restructuring which, in turn, reduces anxiety and depression.

Similar to behaviour therapy, cognitive therapy focuses on solving a specific problem for the client. Unlike psychodynamic therapy, behaviour therapy is open, i.e. the therapist shares her/his method with the client. It is short, lasting between 10-20 sessions. Cognitive Behaviour Therapy is the most popular therapy presently.

Question 6
What is Cognitive Behaviour Therapy (CBT)?
Answer:
Research into the outcome and effectiveness of psychotherapy has conclusively established CBT to be a short and efficacious treatment for a wide range of psychological disorders such as anxiety, depression, panic attacks, borderline personality, etc. CBT adopts a biopsychosocial approach to the delineation of psychopathology. It combines cognitive therapy with behavioural techniques.

The rationale is that the client’s distress has its origins in the biological, psychological, and social realms. Hence, addressing the physical aspects through relaxation procedures, die psychological ones through behaviour therapy and cognitive therapy techniques and the social ones with environmental manipulations makes CBT a comprehensive technique which is easy to use, applicable to a variety of disorders and has proven efficacy.

Question 7.
What is Humanistic-existential Therapy?
Answer:
The humanistic-, existential therapies postulate that psychological distress arises from feelings of loneliness, alienation, and an inability to find meaning and genuine fulfilment in life. Human beings are motivated by the desire for personal, growth and self-actualisation, and mi innate need to grow emotionally. When these needs are curbed by society and family, human beings experience psychological distress.

Self-actualisation is defined as an innate or inborn force that moves the person to become more complex, balanced, and integrated, i.e. achieving complexity and balance without being fragmented. Integrated means a sense of the whole, being a complete person, being in essence the same person in spite of the variety of experiences that one is subjected to. Just as lack of food or water causes distress, the frustration of self-actualisation also causes distress.

Healing occurs when the client is able to perceive the obstacles to self-actualisation in her/his life and is able to remove them. Self-actualisation requires free emotional expression. The family and society curb emotional expression, as it is feared that a free expression of emotions can harm society by unleashing destructive forces. This curb leads to destructive behaviour and negative emotions by thwarting the process of emotional integration.

Therefore, the therapy creates a permissive, nonjudgmental and accepting atmosphere in which the client’s emotions can be freely expressed and complexity, balance and integration could be achieved. The fundamental assumption is that the client has the freedom and responsibility to control her/his own behaviour. The therapist is merely a facilitator and guide.

It is the client who is responsible for the success of therapy. The chief aim of the therapy is to expand the client’s awareness. Healing takes place through a process of understanding the unique personal experience of the client herself/himself. The client initiates the process of self-growth through which healing takes place.

Question 8.
What is Existential Therapy?
Answer:
Victor Frankl, a psychiatrist and neurologist propounded the Logotherapy. Logos is the Greek word for soul anti Logotherapy means treatment for the soul. Frankl calls this process of finding meaning even in life-threatening circumstances the process of meaning-making. The basis of meaning-making is a person’s quest for finding the spiritual truth of one’s existence.

Just as there is an unconscious, which is the repository of instincts (see Chapter 2), there is a spiritual unconscious, which is the storehouse of love, aesthetic awareness, and values of life. Neurotic anxieties arise when the problems of life are attached to the physical, psychological or spiritual aspects of one’s existence. Frankl emphasised the role of spiritual anxieties in leading to meaninglessness and hence it may be called existential anxiety, i.e. neurotic anxiety of spiritual origin.

The goal of logotherapy is to help patients to find meaning and responsibility in their life irrespective of their life circumstances. The therapist emphasises the unique nature of the patient’s life and encourages them to find meaning in their life. In Logotherapy, the therapist is open and shares her/his feelings, values and his/her own existence with the client. The emphasis is on here and now. Transference is actively discouraged. The therapist reminds the client about the immediacy of the present. The goal is to facilitate the client to find the meaning of her/his being.

Question 9.
What is Client-centred Therapy?
Answer:
Client-centred therapy was given by Carl Rogers. Rogers combined scientific rigour with the individualised practice of client-centred psychotherapy. Rogers brought into psychotherapy the concept of self, with freedom and choice as the core of one’s being. The therapy provides a warm relationship in which the client can reconnect with her/his disintegrated feelings. The therapist shows empathy, i.e. understanding the client’s experience as if it were her/his own, is warm and has unconditional positive regard, i.e. total acceptance of the client as she is.

Empathy sets up an emotional resonance between the therapist and the client. Unconditional positive regard indicates that the positive warmth of the therapist is not dependent on what the client reveals or does in the therapy sessions. This unique unconditional warmth ensures that the client feels secure and can trust the therapist. The client feels secure enough to explore her/his feelings. The therapist reflects the feelings of the client in a nonjudgmental manner.

The reflection is achieved by rephrasing the statements of the client, i.e. seeking simple clarifications to enhance the meaning of the client’s statements. This process of reflection helps the client to become integrated. Personal relationships improve with an increase in adjustment. In essence, this therapy helps a client to become her/his real self with the therapist working as a facilitator.

Question 10.
What is Gestalt Therapy?
Answer:
The German word gestalt means ‘whole’. This therapy was given by Frederick (Fritz) Peris together with his wife Laura Peris. The goal of gestalt therapy is to increase an individual’s self-awareness and self-acceptance. The client is taught to recognise the bodily processes and the emotions that are being blocked out from awareness. The therapist does this by encouraging the client to act out fantasies about feelings and conflicts. This therapy can also be used in group settings.

Question 11.
What is Biomedical Therapy?
Answer:
Medicines may be prescribed to treat psychological disorders. Prescription of medicines for the treatment of mental disorders is done by qualified medical professionals known as psychiatrists. They are medical doctors who have specialised in the understanding, diagnosis and treatment of mental disorders. The nature of medicines used depends on the nature of the disorders. Severe mental disorders such as schizophrenia or bipolar disorder require antipsychotic drugs. Common mental disorders such as generalised anxiety or reactive depression may also require milder drugs.

The medicines prescribed to treat mental disorders can cause side effects which need to be understood and monitored. Hence, it is essential that medication is given under proper medical supervision. Even the drugs which normal individuals use to stay awake to study for examinations or to get a ‘high’ at a party have dangerous side effects. These drugs can cause addiction, and harm the brain and the body. Therefore, it is dangerous to self-medicate with drugs which affect the mind.

Factors Contributing to Healing in Psychotherapy:
As we have read, psychotherapy is a treatment of psychological distress. There are several factors which contribute to the healing process. Some of these factors are as follows:

A major factor in healing is the techniques adopted by the therapist and the implementation of the same with the patient/client. If the behavioural system and the CBT of the school are adopted to heal an anxious client, the relaxation procedures and cognitive restructuring largely contribute to the healing.

The therapeutic alliance, which is formed between the therapist and the patient/ client, has healing properties, because of the regular availability of the therapist, and the warmth and empathy provided by the therapist.

At the outset of therapy, while the patient/client is being interviewed in the initial sessions to understand the nature of the problem, s/he unburdens the emotional problems being faced. This process of emotional unburdening is known as catharsis, and it has healing properties.

There are several non-specific factors associated with psychotherapy. Some of these factors are attributed to the patient/client and some to the therapist. These factors are called non-specific because they occur across different systems of psychotherapy and across different clients/patients and different therapists. Non-specific factors attributable to the client/patient are the motivation for change, the expectation of improvement due to the treatment, etc.

These are called patient variables. Non-specific factors attributable to the therapist are positive nature, absence of unresolved emotional conflicts, presence of good mental health, etc. These are called therapist variables.

Ethics in Psychotherapy
Some of the ethical standards that need to be practised by professional psychotherapists are:

  • Informed consent needs to be taken.
  • The confidentiality of the client should be maintained.
  • Alleviating personal distress and suffering should be the goal of all attempts by the therapist.
  • The integrity of the practitioner-client relationship is important.
  • Respect for human rights and dignity.
  • Professional competence and skills are essential.

Question 12.
What are Alternative Therapies available for treatment?
Answer:
Alternative therapies are so-called because they are alternative treatment possibilities to conventional drug treatment or psychotherapy. There are many alternative therapies such as yoga, meditation, acupuncture, herbal remedies and so on. In the past 25 years, yoga and meditation have gained popularity as treatment programmes for psychological distress. Yoga is an ancient Indian technique detailed in the Ashtanga Yoga of Patanjali’S Yoga Sutras.

Yoga as it is commonly called, today either refers to only the asanas or body posture component or to breathing practices or pranayama, or to a combination of the two. Meditation refers to the practice of focusing attention on the breath or on an object or thought or mantra. Here attention is focused. In Vipassana meditation, also known as mindfulness-based meditation, there is no fixed object or thought to hold the attention.

The person passively observes the various bodily sensations and thoughts that are passing through in her or his awareness. The rapid breathing techniques to induce hyperventilation as in Sudarshana Kriya Yoga (SKY) is found to be a beneficial, low-risk, low-cost adjunct to the treatment of stress, anxiety, post-traumatic stress disorder (PTSD), depression, stress-related medical illnesses, substance abuse, and rehabilitation of criminal offenders.

SKY has been used as a public health intervention technique to alleviate PTSD in survivors of mass disasters. Yoga techniques enhance well-being, mood, attention, mental focus, and stress tolerance. Proper training by a skilled teacher and a 30-minute practice every day will maximise the benefits. Research conducted at the National Institute of Mental Health and Neurosciences (NIMHANS), India, has shown that SKY reduces depression.

Further, alcoholic patients who practice SKY have reduced depression and stress levels. Insomnia is treated with yoga. Yoga reduces the time to go to sleep and improves the quality of sleep. Kundalini Yoga taught in the USA has been found to be effective in the treatment of mental disorders. The Institute for Nonlinear Science, University of California, San Diego, USA has found that Kundalini Yoga is effective in the treatment of the obsessive-compulsive disorder.

Kundalini Yoga combines pranayama or breathing techniques with the chanting of mantras. Prevention of repeated episodes of depression may be helped by mindfulness-based meditation or Vipassana. This meditation would help the patients to process emotional stimuli better and hence prevent biases in the processing of these stimuli.

Rehabilitation Of The Mentally Ill:
The treatment of psychological disorders has two components, i.e. reduction of symptoms, and improving the level of functioning or quality of life. In the case of milder disorders such as generalised anxiety, reactive depression or phobia, reduction of symptoms is associated with an improvement in the quality of life. However, in the case of severe mental disorders such as schizophrenia, reduction of symptoms may not be associated with an improvement in the quality of life.

Many patients suffer from negative symptoms such as disinterest and lack of motivation to do work or to interact with people. Rehabilitation is required to help such patients become self-sufficient. The aim of rehabilitation is to empower the patient to become a productive member of society to the extent possible. In rehabilitation, the patients are given occupational therapy, social skills training, and vocational therapy. In occupational therapy, the patients are taught skills such as candle making, paper bag making and weaving to help them to form a work discipline.

Social skills training helps the patients to develop interpersonal skills through role play, imitation and instruction. The objective is to teach the patient to function in a social group. Cognitive retraining is given to improve the basic cognitive functions of attention, memory and executive functions. After the patient improves sufficiently, vocational training is given wherein the patient is helped to gain the skills necessary to undertake productive employment.

Very Short Answer Questions

Question 1:
Psychological Stress
Answer:
These are stresses that we generate ourselves in our minds. These are personal and unique to the person experiencing them and are internal sources of stress. We worry about problems, feel anxiety, or become depressed. These are not only symptoms of stress, but they cause further stress for us.

Question 2:
Emotional Effects
Answer:
Those who suffer from stress are far more likely to experience mood swings and show erratic behavior that may alienate them from family and friends. In some cases this can start a vicious circle of decreasing confidence, leading to more serious emotional problems. Some examples are feelings of anxiety and depression, increased physical tension, increased psychological tension and mood swings.

Question 3:
Behavioral Effects
Answer:
Stress affects our behavior in the form of eating less nutritional food, increasing intake of stimulants such as caffeine, excessive consumption of cigarettes, alcohol and other drugs such as tranquilizers etc. Tranquilizers can be addictive and have side effects such as loss of concentration, poor coordination and dizziness. Some of the typical behavioral effects of stress seen are disrupted sleep patterns, increased absenteeism, and reduced work performance.

Question 4:
Resistance stage: If stress is prolonged.
Answer:
The resistance stage begins. The parasympathetic nervous system calls for more cautious use of the body’s resources. The organism makes efforts to cope with the threat, as through confrontation.

Question 5:
Exhaustion stage:
Answer:
Continued exposure to the same stressor or additional stressors drains the body of its resources and leads to the third stage of exhaustion. The physiological systems involved in alarm reaction and resistance become ineffective and susceptibility to stress-related diseases such as high blood pressure becomes more likely. Selye’s model has been criticized for assigning a very limited role to psychological factors in stress. Researchers have reported that the psychological appraisal of events is important for the determination of stress. How people respond to stress is substantially influenced by their perceptions,

Question 6:
Emotion-oriented Strategy
Answer:
This can involve efforts to maintain hope and to control one’s emotions; it can also involve venting feelings of anger and frustration, or deciding that nothing can be done to change things. For example, tell myself that it is not really happening to me, or worry. about what I am going to do.

Question 7:
Avoidance-oriented Strategy
Answer:
This involves denying or minimizing the seriousness of the situation; it also involves conscious suppression of stressful thoughts and their replacement by self-protective thoughts. Examples of this are watching TV, phone up a friend, or try to be with other people. Lazarus and Folkman has conceptualized coping as a dynamic process rather than an individual trait. Coping refers to constantly changing cognitive and behavioral efforts to master, reduce or tolerate the internal or external demands that are created by the stressful transaction.

Question 8:
Relaxation Techniques
Answer:
It is an active skill that reduces symptoms of stress and decreases the incidence of illnesses such as high blood pressure and heart disease. Usually, relaxation starts from the lower part of the body and progresses up to the facial muscles in such a way that the whole body is relaxed.

Question 9:
Cognitive Behavioural Techniques
Answer:
These techniques aim to inoculate people against stress. Stress inoculation training is one effective method developed by Meichenbaum. The essence of this approach is to replace negative and irrational thoughts with positive and rational ones. There are three main phases in this: assessment, stress reduction techniques.

Question 10:
Stress Resistant Personality
Answer:
Recent studies by Kobasa have shown that people with high levels of stress but low levels of illness share three characteristics, which are referred to as the personality traits of hardiness. It consists of ‘the three Cs ’, i.e. commitment, control, and challengene.

Short Answers Questions

Question 1:
Define two effects of psychology.
Answer:

Emotional Effects:
Those who suffer from stress are far more likely to experience mood swings and show erratic behavior that may alienate them from family and friends. In some cases this can start a vicious circle of decreasing confidence, leading to more serious emotional problems. Some examples are feelings of anxiety and depression, increased physical tension, increased psychological tension, and mood swings. Box 3.2 presents the phenomenon of ‘examination Anxiety’.

Physiological Effects:
When the human body is placed under physical or psychological stress, it increases the production of certain hormones, such as adrenaline and cortisol. These hormones produce marked changes%i in heart rate, blood pressure levels, metabolism and physical activity. Although this physical reaction will help us to function more effectively when we are under pressure for short periods of time, it can be extremely damaging to the body in the long-term effects. Examples of physiological effects are the release of epinephrine and nor-epinephrine, slowing down of the digestive system, expansion of air passages in. the lungs, increased heart rate, and constriction of blood vessels.

Question 2:
What is burnout?
Answer:
You must have often observed that many of your friends (maybe including yourself as well!) fall sick during examination time. They suffer from stomach upsets, body aches, nausea, diarrhea, fever, etc. You must have also noticed that people who are unhappy in their personal lives fall sick more often than those who are happy and enjoy life. Chronic daily stress can divert an individual’s attention from caring for herself or himself. When stress is prolonged, it affects physical health and impairs psychological functioning.

People experience exhaustion and attitudinal problems when the stress due to demands from the environment and constraints are too high and little support is available from family and friends. Physical exhaustion is seen in the signs of chronic fatigue, weakness, and low energy. Mental exhaustion appears in the form of irritability, anxiety, and feelings of helplessness and hopelessness. This state of physical,, emotional and psychological exhaustion is known as burnout.

Question 3:
What is General Adaptation Syndrome?
Answer:
What happens to the body when stress is prolonged? Selye studied this issue by subjecting animals to a variety of stressors such as high temperature, X-rays and insulin injections, in the laboratory over a long period of time. He also observed patients with various injuries and illnesses in hospitals. Selye noticed a similar pattern of bodily response in all of them. He called this pattern the General Adaptation Syndrome (GAS). According to him, GAS involves three stages: alarm reaction, resistance, and exhaustion (see Fig.3,3).

Alarm reaction stage:
The presence of a noxious stimulus or stressor leads to the activation of the adrenal pituitary-cortex system. This triggers the release of hormones producing the stress response. Now the individual is ready for fight or flight.

Resistance stage:
If stress is prolonged, the resistance stage begins. The parasympathetic nervous system calls for more cautious use of the body’s resources. The organism makes efforts to cope with the threat, as through confrontation.

Question 4:
Lifestyle.
Answer:
Hardiness is a set of beliefs about oneself, the world, and how they interact. It takes shape « as a.sense of personal commitment to what you are doing, a sense of control over your life, and a feeling of challenge. Stress-resistant personalities have control which is a sense of purpose and direction in life; commitment to work, family, hobbies, and social life and challenge, that is, they see changes in life as normal and positive rather than as a threat. Everyone does not have these characteristics, many of us have to relearn specific life skills in areas such as rational thinking to equip ourselves better to cope with the demands of everyday life, etc.

Question 5:
Define 3 coping strategies.
Answer:
The three coping strategies given by Endler and Parker are:

Task-oriented Strategy:
This involves obtaining information about the stressful situation and about alternative courses of action and their probable outcome; it also involves deciding priorities and acting so as to deal directly with the stressful situation. For example, schedule my time better, or think about how I have solved similar problems.

Emotion-oriented Strategy:
This can involve efforts to maintain hope and to control one’s emotions; it can also involve venting feelings of anger and frustration, or deciding that nothing can be done to change things. For example, tell myself that it is not really happening to me, or worry about what I am going to do.

Avoidance-oriented Strategy:
This involves denying or minimizing the seriousness of the. situation; it also involves conscious suppression of stressful thoughts and their replacement by self-protective thoughts. Examples of this are watching TV, phone up a friend, or try to be with other people.

Question 6:
Stress-Resistant Personality.
Answer:
Recent studies by Kobasa have shown that people with high levels of stress but low levels of illness share three characteristics, which are referred to as the personality traits of hardiness. It consists of ‘the three Cs’, i.e. commitment, control, and challenge.

Question 7:
Define 3 life skills that will help in life challenges the 3 life skills.
Answer:

Assertiveness :
Assertiveness is a behavior or skill that helps to communicate, clearly and confidently, our feelings, needs, wants and thoughts. It is the ability to say no to a request, to state an opinion without being self-conscious, or to express emotions such as love, anger, etc. openly. If you are assertive, you feel confident and have high self-esteem and a solid sense of your own identity.

Time Management:
The way you spend your time determines the quality of your life. Learning how to plan time and delegate can help to relieve the pressure. The major way to reduce time stress is to change one’s perception of time. The central principle of time management is to spend your time doing the things that you value, or that help you to achieve your goals. It depends on being realistic about what you know and that you must do it within a certain time period, knowing what you want to do and organizing your life to achieve a balance between the two.

Rational Thinking :
Many stress-related problems occur as a result of distorted thinking. The way you think and the way you feel are closely connected. When we are stressed, we have an. inbuilt selective bias to attend to negative thoughts and images from the past

Question 8:
Overcoming Unhelpful Habits :
Answer:
Unhelpful habits such as perfectionism, avoidance, procrastination, etc. are strategies that help to cope in the short-term but which make one more vulnerable to stress. Perfectionists are persons who have to get everything just right. They have difficulty in varying standards according to factors such as time available, consequences of not being able to stop work and the effort needed. They are more likely to feel tense and find it difficult to relax, are critical of self and others, and may become inclined to avoid challenges.

Avoidance is to put the issue under the carpet and refuse to accept or face it. Procrastination means putting off what we know we need to do. We all are guilty, of saying “I will do it later”. People who procrastinate are deliberately avoiding confronting their fears of failure or rejection. Various factors have been identified which facilitate the development of positive health. Health is a state of complete physical, mental, social and spiritual well-being and not merely the absence of disease or infirmity.

Question 9:
Social Support:
Answer:
Social support is defined as the existence and availability of people on whom we can rely upon, people who let us know that they care about, value and love us. Someone who believes that she belongs to a social network of communication and mutual obligation experiences social support. Perceived support, i.e. the quality of social support is positively related to health and well-being, whereas social network, i.e, the quantity of social support is unrelated to well-being because it is very time consuming and demanding to maintain a large social network.

Studies have revealed that women exposed to life event stresses, who had a close friend, were less likely to be depressed and had lesser medical complications during pregnancy. Social support can help to provide protection against stress. People with high levels of social support from family and friends may experience less stress when they confront a stressful experience and they may cope with it more successfully.

Question 10:
What is Noise?
Answer:
Children’s reading abilities, cognitive development, physiological indicators, and motivational tasks are affected by exposure to noise. The most common noises that children are exposed to are transportation (e.g. cars, airplanes), music, and other people. Evans’ research reveals significant reading delays for children living near airports and exposed to airport noise. He and his colleagues found these delays in reading to occur at noise levels far below those required to produce hearing damage or loss.

Chronic and acute noise exposure also affects cognitive development, particularly long-term memory, especially if the task is complex. Short-term memory appears to be less affected, but this is dependent upon the volume of noise. One way that children adapt to chronic noise is by disregarding or ignoring auditory input. A consequence of this coping strategy is that children also tune out speech, which is a basic and required component of reading. As a result, not only are children’s reading abilities affected, but also their abilities at tasks that require speech perception.

Noise levels also indirectly influence children’s cognitive development via their effect on the adults and teachers who interact with children. Teachers in noisy schools are more fatigued, annoyed, and less patient than teachers in quieter schools. Teachers in noisy schools also lose instruction time due to noise distractions and have a compromised teaching style. Children exposed to chronic loud noise also experience a rise in blood pressure and stress hormones. And children as young as four are less motivated to perform on challenging language and pre-reading tasks under conditions of exposure to chronic noise.

Question 11:
Housing and Quality of Neighborhood.
Answer:
Housing quality and the neighborhoods in which houses are situated have also been investigated in relation to children’s socioemotional development. For example, families living in high-rise housing, as opposed to single-family residences, have fewer relationships with neighbors, resulting in less social support. Studies on housing and the quality, of neighborhoods, have also examined the role of chaos in children’s environments finding an association between chaotic home environments and levels of psychological distress among middle school children.

Research has identified the physical characteristics of neighborhoods that significantly influence children’s development. These characteristics include residential instability, housing quality, noise, crowding, toxic exposure, quality of municipal services, retail services, recreational opportunities, including natural settings, street traffic, accessibility of transportation, and the physical quality of both educational and health facilities.

Perhaps not surprisingly, Evans’s research findings support the therapeutic effects of children’s exposure to natural settings. Natural settings are preferred by children and allow them to exercise gross motor abilities as well as engage in social interactions. In addition, these settings also alleviate the adverse effects of children’s exposure to chronic stress.

Question 12:
What impact of the environment have on human behavior?
Answer:
Guard against additional, interior noise sources. Individuals living in noisy environments often habituate or become accustomed to the noise level. Aim to reduce the existing noise instead of adding other sources of noise. Check the volume level on your child’s music devices (e.g., iPod, Walkman; it is too loud if someone else can hear the music). If he listens to his favorite music too loudly, make proper volume adjustments. Also monitor the volume level on computers, televisions, and other electronic devices, keeping them as low as possible.

Engage your child’s Children to ignore and tune out speech as a way of coping with environmental overstimulation. Take notice if your child is not paying attention or listening to your speech and if so, intervene. Take your child to a quiet outdoor nature spot or a quiet indoor location Such as the local library. This is especially important during the preschool and early elementary school years (ages 3-6 years) when children are learning to read.

Tune in instead of tuning out. Parents living under high noise exposure appear to withdraw, be less responsive and talk less to their children. The natural tendency is to disengage from speaking and reading to children so as not to compete with the noise. These coding strategies negatively affect children’s reading and cognitive abilities.

Long Questions With Answers

Question 1:
What is personality?
Answer:
The personality is derived from the latin word persona the mask used in theatre to change their persona. Personality is the physical and behaviour appearance of individual.

Question 2:
What is self? How does the Indian notion of self differ from the Western notion?
Answer:
Self refers to the totality of an individual’s conscious experiences, ideas, thoughts and feelings with regard to herself or himself. The Indian notion of self and the Western notion of self differ from each other by a number of important features. The most important distinction is the way the boundary is drawn between the self and the other.

In the Western view, this boundary appears to be relatively fixed on the other hand, the Indian view of self is Characterised by the shifting nature of this boundary. Thus, our self at one moment of time expands to fuse with the cosmos or include others. But at the next moment, it seems to be completely withdrawn from it and focused fully on individual self (e.g., our personal needs or goals).

The Western view seems to hold clear dichotomies between self and other, man and nature, and subjective and objective while the Indian view does not make such clear dichotomies. In the Western culture, the self and the group exist as two different entities with clearly defined boundaries i.e. individual members of the group maintain their individuality while in the Indian culture, the self is generally not separated from one’s own group; rather both remain in a state of harmonious co-existence.

In Western culture, on the other hand, they often remain at a distance. That is why many Western cultures are characterised as individualistic, whereas many Asian cultures are characterised as collectivistic.

Question 3:
What is meant by delay of gratification? Why is it considered important for adult development?
Answer:
Delay of gratification also known as self-control is a practice which means learning to delay or defer the more pleasurable or fun-loving needs and rewarding later.
It is considered important for adult development because any situations of life require resistance to situational pressures and control, over ourselves. Human beings can control their behaviour the way they want which is possible through what is commonly known as ‘will power’. Delay or defer the satisfaction of certain needs or practising self-control play a key role in the fulfilment of long-term goals.

Indian cultural tradition provides us with certain effective mechanisms (e.g. fasting in vrata or roza and non-attachment with worldly things) for developing self-control. A number of psychological techniques of self-control have been suggested which are:

  •  Observation of own behaviour:
    This provides us with the necessary information that may be used to change, modify, or strengthen certain, aspects of self.
  • Self-instruction:
    It is another important technique. We often instruct ourselves to do something and behave the way we want to. Such instructions are quite effective in self-regulation.
  • Self-reinforcement:
    It involves rewarding behaviours that have pleasant outcomes. For example, you may go to see a movie with friends, if you have done well in an examination. These techniques have been tried out and found quite effective with respect to self-regulation and self-control.

Question 4:
How do you define personality? What are the main approaches to the study of personality?
Answer:
Personality refers to psychophysical characteristics of a person that are relatively stable across situations and over time and make her or him unique. It also defines our existence and the ways in which our experiences are organised and show up in our behaviour.
A number of approaches and theories have been developed to understand and explain personality. The main approaches to the study of personality are:

  • The type approach
  • The trait approach
  • The interactional approach
  • Psychodynamic approach
  • Post frendian approach
  • Behavioural approach
  • Cultural approach
  • Humanistic approach

Question 5:
What is trait approach to personality? How does it differ from the type approach?
Answer:
The trait approach is very similar to our common experience in everyday life. These theories are mainly concerned with the description or characterisation of basic components of personality. It tries to discover the ‘building blocks’ of personality. Human beings display a wide range of variations-in psychological attributes, yet it is possible to club them into a smaller number of personality traits. For example, when we come to know that a person is sociable, we assume that s/he will not only be cooperative, friendly and helpful, but also engage in behaviours that involve other social components.

Thus, trait approach attempts to identify primary characteristics of people. A trait is considered as a relatively enduring attribute or quality on which one individual differs from another. They include a range of possible behaviours that are activated according to the demands of the situation.

  • The type approaches attempts to comprehend human personality by examining certain broad patterns in the observed behavioural characteristics of individuals while the trait approach focuses on the specific psychological attributes along which individuals tend to differ in consistent and stable ways.
  • Each behavioural pattern of type approach refers to one type in which individuals are placed in terms of the similarity of their behavioural characteristics with that pattern while in trait approach refers to the degree of presence or absence of the concerned behavioural quality on which individuals can be rated.

Question 6:
How does Freud explain the structure of personality?
Answer:
According to Freud’s theory, there are three primary structural elements of personality which are id, ego, and superego. They reside in the unconscious as forces and they can be inferred from the ways people behave.

CHSE Odisha Class 12 Psychology Unit 1 Long Answer Questions Part - 4 Q6

Id:
It is the source of a person’s instinctual energy. It deals with the immediate gratification of primitive needs, sexual desires and aggressive impulses. It works on the pleasure principle, which assumes that people seek pleasure and try to avoid pain. Freud considered much of a person’s instinctual energy to be sexual, and the rest as aggressive. Id does not care for moral values, society, or other individuals.

Ego:
It grows out of id, and seeks to satisfy an individual’s instinctual needs in accordance with reality. It works by the reality principle and often directs the id towards more appropriate ways of behaving. The ego is patient, reasonable, and works by the reality principle. .

Superego:
The best way to characterise the superego is to think of it as the moral branch of mental functioning. The superego tells the id and the ego whether the gratification in a particular instance is ethical. It helps control the id by the internalising parental authority through the process of socialisation. Thus, in terms of individual functioning, Freud thought of the unconscious as being composed of three competing forces.In some people, the id is stronger than the superego; in others, it is the superego. The relative strength of the id, ego and superego determines each person’s stability. Freud also assumed that id is energised by two instinctual forces, called life instinct and the death instinct. He paid less attention to the death instinct and focused more on the life (or sexual) instinct The instinctual life force that energises the id is called libido. It works on the pleasure principle and seeks immediate gratification.

Question 7:
How would Horney’s explanation of depression be different from that of Alfred Adler?
Answer:
Homey was another disciple of Freud who developed a theory that deviated from basic Freudian principles. She adopted a more optimistic view of human life with an emphasis on human growth and self-actualisation. Homey’s major contribution lies in her challenge to Freud’s treatment of women as inferior. According to her, each sex has attributes to be admired by the other, and neither sex can be viewed as superior or inferior. She countered that women were more likely to be affected by social and cultural factors than biological factors.

She argued that psychological disorders were caused by disturbed interpersonal relationships during childhood. When parents’ behaviour toward a child is indifferent, discouraging, and erratic, the child feels insecure and a feeling called basic anxiety results. Deep resentment toward parents or basic hostility occurs due to this anxiety. By showing excessive dominance or indifference, or by providing too much or too little approval, parents can generate among children feelings of isolation and helplessness which interfere with their healthy development.

In contrast to that, Adler’s theory is known as individual psychology. His basic assumption is that human behaviour is purposeful and goal-directed. Each one of us has the capacity to choose and create. Our personal goals are the sources of our motivation. The goals that provide us with security and help us in overcoming feelings of inadequacy are important in our personality development. In Adler’s view, every individual suffers from feelings of inadequacy and guilt, i.e. inferiority complex, which arise from childhood. Overcoming this complex is essential for optimal personality development

Question 8:
What is the main proposition of the humanistic approach to personality? What did Maslow mean by self-actualisation?
Answer:
Carl Rogers and Abraham Maslow have particularly contributed to the development of the humanistic perspective on personality. The most important idea proposed by Rogers is that of a fully functioning person. He believes that fulfilment is the motivating force for personality development. People try to express their capabilities, potential and talents to the fullest extent possible. There is an inborn tendency among persons that directs them to actualise their inherited nature.

Rogers makes two basic assumptions about human behaviour. One is that behaviour is goal-directed and worthwhile. The second is that people (who are innately good) will almost always choose adaptive, self-actualising behaviour. Rogers views personality development as a continuous process. It involves learning to evaluate oneself and mastering the process of self-actualisation. He recognises the role of social influences in the development of self-concept.

When social conditions are positive, self-concept and self-esteem are high. In contrast, when the conditions are negative, the. self-concept and self-esteem are low. People with high self-concept and self-esteem are generally flexible and open to new experiences so that they can continue to grow and self-actualise. Maslow has given a detailed account of psychologically healthy people in terms of their attainment of self-actualisation, a state in which people have reached their own fullest potential.

Maslow had an optimistic and positive view of man who has the potential for love, joy and to do creative work. Human beings are considered free to shape their lives and to self-actualise. Self-actualisation becomes possible by analysing the motivations that govern our life. We know that biological, security and belongingness needs (called survival needs) are commonly found among animals and human beings. Thus, an individual’s sole concern with the satisfaction of these needs reduces her/him to the level of animals. The real journey of human life begins with the pursuit of self-esteem and self-actualisation needs. The humanistic approach emphasises the significance of positive aspects of life.

Question 9:
Discuss the main observational methods used in personality assessment. What problems do we face in using these methods?
Answer:
The main observational methods used in personality assessment are interviews, observation, ratings, nomination and situational tests.

Interview:
It is a commonly used method for assessing personality. This involves talking to the person being assessed and asking specific Qs. Diagnostic interviewing generally involves in-depth interviewing which seeks to go beyond the replies given by the person. Interviews may be structured or unstructured depending on the purpose or goals of the assessment. In unstructured interviews, the interviewer seeks to develop an impression about a person by asking a number of Qs. The way a person presents her/himself and answers the Qs carries enough potential to reveal her/his personality. The structured interviews address very specific Qs and follow a set procedure. This is often done to make objective comparisons of persons being interviewed. Use of rating scales may further enhance the objectivity of evaluations.

Observation:
Observation of behaviour is another method which is very commonly used for the assessment of personality. Use of observation for personality assessment is a sophisticated procedure that cannot be carried out by untrained people. It requires careful training of the observer and a fairly detailed guideline about the analysis of behaviours in order to assess the personality of a given person. For example, a clinical psychologist may like to observe her/his client’s interaction with family members and home visitors. With carefully designed observation, the clinical psychologist may gain considerable insight into a client’s personality.

Behavioural Ratings :
These are frequently used for the assessment of personality in educational and. industrial settings. Behavioural ratings are generally taken from people who know the assessee intimately and have interacted with her/him over a period of time or have had a chance to observe her/him. They attempt to put individuals into certain categories in terms of their behavioural qualities. The categories may involve different numbers or descriptive terms. It has been found that use of numbers or general descriptive adjectives in rating scales always creates confusion for the rater. In order to use ratings effectively, the traits should be clearly defined in terms of carefully stated behavioural anchors.

Nomination:
This method is often used in obtaining peer assessment. It can be used with persons who have been in long-term interaction and who know each other very well. In using nomination, each person is asked to choose one or more persons of the group with whom she/he would like to work, study, play or participate in any other activity. The person may also be asked to specify the reason for her/his choices.

Situational Tests :
A variety of situational tests have been devised for the assessment of personality. The most commonly used test of this kind is the situational stress test. It provides us with information about how a person behaves under stressful situations. The test requires a person to perform a given task with other persons who are instructed to be non-c6operative and interfering. The test involves a kind of role-playing. The person is instructed to play a role for which s/he is observed. A verbal report is also obtained on what s/he was asked to do. The situation may be a realistic one, or it may be created through a video play. Problems faced in using these methods.

Observation and interview methods are characterised by the following limitations:

  • Professional training required for the collection of useful data through these methods is quite demanding and time-consuming.
  • The maturity of the psychologist is a precondition for obtaining valid data through these techniques.
  • The mere presence of the observer may contaminate the results. As a stranger, the observer may influence the behaviour of the person being observed and thus not obtain good data. Behavioural ratings suffer from the following major limitations.
  • Raters often display certain biases that colour their judgments of different traits. For example, most of us are greatly influenced by a single favourable or unfavourable trait. This often forms the basis of a rater’s overall judgment of a person. This tendency is known as the halo effect.
  • Raters have a tendency to place individuals either in the middle of the scale (called middle category bias) by avoiding extreme positions, or in the extreme positions (called extreme response bias) by avoiding middle categories on the scale. These tendencies can be overcome by providing raters with the appropriate training or by developing such scales in which the response bias is likely to be small.
    Nominations received may be analysed to understand the personality and behavioural qualities of the person. This technique has been found to be highly dependable, although it may also be affected by personal biases.

Question 10:
What is meant by structured personality tests? Which are the two most widely * used structured personality tests? “
Answer:
Self-report measures is a fairly structured personality test. This was used by Allport who suggested that the best method to assess a person is by asking her/him about herself/ himself. This led to the use of self-report measures. These are fairly structured measures, often based on theory, that require subjects to give verbal responses using some kind of rating scale. The method requires the subject to objectively report her/his own feelings with respect to various items. The responses are accepted at their face value. They are scored in quantitative terms and interpreted on the basis of norms developed for the test.

The two most widely used structured personality tests are:

The Minnesota Multiphasic Personality Inventory (MMPI):
This inventory is widely used as a test in personality assessment. Hathaway and McKinley developed this test as a helping tool for psychiatric diagnosis, but the test has been found very effective in identifying varieties of psychopathology. Its revised version is available as MMPI-2. It consists of 567 statements. The subject has to judge each statement as ‘true’ or ‘false’ for her/him. The test is divided into 10 subscales, which seek to diagnose hypochondriasis, depression, hysteria, psychopathic deviate, masculinity-femininity, paranoia, psychasthenia, schizophrenia, mania and social introversion. In India, Mallick and Joshi have developed the Jodhpur Multiphasic Personality Inventory (JMPI) along the lines of MMPI.

Eysenck Personality Qnaire (EPQ):
Developed by Eysenck this test initially assessed two dimensions of personality, called introverted-extraverted and emotionally stable-emotionally unstable. These dimensions are characterised by 32 personality traits. Later on, Eysenck added a third dimension, called psychoticism. It is linked to psychopathology that represents a lack of feeling for others, a tough manner of interacting with people and a tendency to defy social conventions. A person scoring high on this dimension tends to be hostile, egocentric and antisocial. This test is also widely used.

Question 11:
Explain how projective techniques assess personality. Which projective tests of personality are widely used by psychologists?
Answer:
Projective technique is an indirect method of assessment of personality. This provides us with a real picture of an individual’s personality using the indirect method.
Projective techniques were developed to assess unconscious motives and feelings. These techniques are based on the assumption that a less structured or unstructured stimulus or situation will allow the individual to project her/his feelings, desires and needs onto that situation.

These projections are interpreted by experts. A variety of projective techniques have been developed; they use various kinds of stimulus materials and situations for assessing personality. Some of them require reporting associations with stimuli (e.g., words, inkblots), some involve story writing around pictures, some require sentence completions, some require expression through drawings, and some require a choice of stimuli from a large set of stimuli.

The projective tests of personality which are widely used by psychologists are:

1.The Rorschach Inkblot Test:
This test was developed by Hermann Rorschach. The test consists of 10 inkblots. Five of them are in black and white, two with some red ink, and the remaining three in some pastel colours. The blots are symmetrical in design with a specific shape or form. Each blot is printed in the centre of white cardboard of about 7″? 10″ size. The blots were originally made by dropping ink on a piece of paper and then folding the paper in half (hence called the inkblot test). The cards are administered individually in two phases.

  • In the first phase, called performance proper, the subjects are shown the cards and are asked to tell what they see in each of them.
  • In the second phase, called inquiry, a detailed report of the response is prepared by asking the subject to tell where, how, and on what basis was a particular response made. Fine judgment is necessary to place the subject’s responses in a meaningful context. The use and interpretation of this test require extensive training. Computer techniques too have been developed for the analysis of data.

2. The Thematic Apperception Test (TAT):
This test was developed by Morgan and Murray. It is a little more structured than the Inkblot test. The test consists of 30 black and white picture cards and one blank card. Each picture card depicts one or more people in a variety of situations. Each picture is printed on a card. Some cards are used with adult males or females. Others are used with boys or girls. Still, others are used in some combinations. Twenty cards are appropriate for a subject, although a lesser number of cards (even five) have also been successfully used. The cards are presented one at a time. The subject is asked to tell a story describing the situation presented in the picture.

3. Sentence Completion Test:
This test makes use of a number of incomplete sentences. The starting part of the sentence is first presented and the subject has to provide an ending to the sentence. It is held that the type of endings used by the subjects reflects their attitudes, motivation and conflicts. The test provides subjects with several opportunities to reveal their underlying unconscious motivations. A few sample items of a sentence completion test are given below.

  • My father ________.
  • My greatest fear is ________.
  • The best thing about my mother is _________.
  • I am proud of ________.

Question 12:
Arihant wants to become a singer even though he belongs to a family of doctors. Though his family members claim to love him but strongly disapprove his choice
of career. Using Carl Rogers’ terminology, describe the attitudes shown by Arihant’s family.
Answer:
According to Carl Rogers’ terminology, People try to express their capabilities, potentials and talents to the fullest extent possible. There is an inborn tendency among persons that directs them to actualise their inherited nature. He made two assumptions about human behaviour. One is that behaviour is goal-directed and worthwhile. The second is that people (who are innately good) will almost always choose adaptive, self-actualising behaviour.

He noted that self was an important element in the experience of his clients. Thus, his theory is structured around the concept of self. The theory assumes that people are constantly engaged in the process of actualising their true self. He recognises the role of social influences in the development of self-concept. When social conditions are positive, self-concept and self-esteem are high. In contrast, when the conditions are negative, the self-concept and self-esteem are low.

Thus, Arihant’s family will disapprove his choice of career as they want to be a doctor to satisfy their self-concept. Arihant’s family will want him to pursue a career of their inherited nature and will become stubborn about it even though they love him, They will try their best to stop him from choosing the career of a singer which is not in their inheritance.

Long Questions With Answers

Question 1:
Notes on Piaget and Education.
Answer:
Piaget’s theory has had a major impact on education, especially during early childhood. Three educational principles derived from his theory continue to have a widespread influence on teacher training and classroom practices:

Discovery learning:
In a Piagetian classroom, children are encouraged to discover for themselves through spontaneous interaction with the environment. Instead of presenting ready-made knowledge verbally, teachers provide a rich variety of activities designed to promote exploration-art materials, puzzles, table games, dress-up clothing, building blocks, books, measuring tools, musical instruments and more.

Sensitivity to children’s readiness to learn:
A Piagetian classroom does not try to speed up development. Instead, Piaget believed that appropriate learning experiences build on children’s current thinking. Teachers watch and listen to their students, introducing experiences that enable them to practice newly discovered schemes and that are likely to challenge their incorrect ways of viewing the world. But teachers do not impose new skills before children indicate they are interested and ready.

Acceptance of individual differences:
Piaget’s theory assumes that all children go through the same sequence of development, but at different rates. Therefore, teachers must plan activities for individual children and small groups rather than just for the whole class. In addition, teachers evaluate educational progress by comparing each child to that child’s own previous development. They are less interested in how children measure up to normative standards, dr the average performance of same-age peers.

Question 2:
Discuss the Erikson’s theory: Initiative Versus Guilt.
Answer:
Erikson described early childhood as a period of‘ ‘vigorous unfolding.” Once children have a sense of autonomy, they become less contrary than they were as toddlers. Their energies are freed for tackling the psychological conflict of the preschool years: initiative versus guilt. As the word initiative suggests, young children have a new sense of purposefulness. They are eager to tackle new tasks, join in activities with peers and discover what they can do with the help of adults. And they also make strides in conscience development.

Erikson’s regarded play as a central means through which young children find out about themselves and their social world. Play permits preschoolers to try out new skills with little risk of criticism and failure. It also creates a small social organization of children who must cooperate to achieve common goals. Around the world, children act out family scenes and highly visible occupations-police officer, doctor and nurse. It is known Erikson’s theory builds on Freud’s psychosexual stages. In Freud’s well-known.

Oedipus and Electra conflicts, to avoid punishment and maintain the affection of parents, children form a superego, or conscience, by identifying with the same-sex parent. That is, they take the parent’s characteristics into their personality and as a result, adopt the moral and gender-role standards of their society. Each time the child disobeys standards of conscience, painful feelings of guilt occur.

For Erikson, the negative outcome of early childhood is an overly strict superego that causes children to feel too much guilt because they have been threatened, criticized, and punished excessively by adults. When this happens, preschoolers’ exuberant play and bold efforts to master new tasks break down. Although Freud’s Oedipus and Electra conflicts are no longer regarded as satisfactory explanations of conscience development.

Erikson’s image of initiative captures the diverse changes in young children’s emotional and social lives. The preschool years are, indeed, a time when children develop a confident self-image, more effective control over their emotions, new social skills, the foundations of morality and a clear sense of themselves as boy or girl.

Question 3:
What Makes Authoritative Child Rearing So Effective?
Answer:
Authoritative child-rearing seems to create an emotional context for positive parental influence. First, warm, involved parents who are secure in the standards they hold for their children provide models of caring concern as well as confident,’ self-controlled behavior.  Second, control that appears fair and reasonable to the child, not arbitrary, is far more likely to be complied with and internalized.

Finally, authoritative parents make demands and engage in autonomy granting that fits with their children’s ability to take responsibility for their own behavior. As a result, these parents let children know that they are competent individuals who can do things successfully for themselves, thereby fostering high self-esteem and cognitive and social maturity.

Question 4:
Characteristics of Adolescence.
Answer:
Like every important period during the life span, adolescence has certain characteristics that distinguish it from the periods that preceded it and the periods that will follow it. These characteristics are explained briefly below.

Adolescence is an important period:
As all periods in the life span are important, some are more important than others because of their immediate effects on attitudes and behavior, whereas others are significant because of their long-term effects. Adolescence is one of the periods when both the immediate effects and long-term effects are important. Some periods are important for their physical and some for their psychological effects. Adolescence is important for both. Accompanying these rapid and important physical developments, especially during the early adolescent period, rapid mental developments occur. These give rise to the need for mental adjustments and the necessity for establishing new attitudes, values and interests.

Adolescence is a transitional period:
Transition does not mean a break with or a change from what has gone before but rather a passage from one stage of development to another. This means that what has happened before will leave its mark on what happens now and in the future. Children, when they go from childhood to adulthood, must “put away childish things” and they must also learn new patterns of behavior and attitudes to replace those they have abandoned. However, it is important to realize that what happened earlier has left its mark and will influence these new patterns of behavior and attitudes.

The psychic structure of the adolescent has its roots in childhood and many of its characteristics that are generally considered as typical of adolescence appear and are already present during late childhood. The physical changes that take place during the early years of adolescence affect the individual’s behavioral level and lead to reevaluations and a shifting adjustment of values. During any transitional period, the individual’s status is vague and there is confusion about the roles the individual is expected to play.

The adolescent, at this time, is neither a child nor an adult. If adolescents behave like children, they are told to “act their age.” If they try to act like adults, they are often accused of being “too big for their behaviors” and are reproved for their attempts to act like adults. On the other hand, the ambiguous status of today’s adolescents is advantageous in that it gives them time to try out different lifestyles | and decide what patterns of behavior, values, and attitudes meet their needs best.

Adolescence is a period of change:
The rate of change in attitudes and behavior during adolescence parallels the rate of physical change. Dining early adolescence, when physical changes are rapid, changes in attitudes and behavior are also rapid. As physical changes slow down, so do altitudinal and behavioral changes.

There are five almost universal concomitants of the changes that occur during adolescence.

  • The first is heightened emotionality, the intensity of which depends on the rate at which the physical and psychological changes are taking place. Because these changes normally occur more rapidly during early adolescence, heightened emotionality is generally more pronounced in early than in late adolescence.
  • Second, the rapid changes that accompany sexual maturing make young adolescents unsure of themselves, of their capacities and of their interests. They have strong feelings of instability which are often intensified by the ambiguous treatment they receive from parents and teachers.
  • Third, changes in their bodies, their interests, and in the roles the social group expects them to play create new problems.To young adolescents, these may seem more numerous and less easily solved than any they have had to face before. Until they have solved their problems to their satisfaction, they will be preoccupied with them and with themselves.
  • Fourth, as interests and behavior patterns change, so do values. What was important to them as children seems less important to them now that they are near adults. For example, most adolescents no longer think that a large number of friends is a more important indication of popularity than friends of the type that are admired and respected by their peers. They now recognize quality as more important than quantity.
  • Fifth, most adolescents are ambivalent about changes. While they want and demand independence, they often dread the responsibilities that go with independence and Q their ability to cope with these responsibilities.

Adolescence is a Problem Age:
While every age has its problems, those of adolescence are often especially difficult for boys and girls to cope with. There are two reasons for this. First, throughout childhood, their problems were met and solved, in part at least, by parents and teachers. As a result, many adolescents are inexperienced in coping with problems alone. Second, because adolescents want to feel that they are independent, they demand the right of coping with their own problems, rebuffing attempts on the part of parents and teachers to help them.

Because of their inability to cope with problems alone as well as they believe they can, many adolescents find that the solutions do not always come up to their expectations. As Anna Freud has explained, “Many failures, often with tragic consequences in these respects, are due not to the individual’s incapacity as such but merely to the fact that such demands are made on him at a time in life when all his energies are engaged otherwise, namely, in trying to solve the major problem created for him by normal sexual growth and development”.

Adolescence is a Time of Search for Identity:
Throughout the gang age of late childhood, conformity to group standards, is far more important to older children than individuality. As was pointed out earlier, in dress, speech, and behavior older children want to be as nearly like their gang-mates as possible. Any deviation from the group standard is likely to be a threat to group belonging. In the early years of adolescence, conformity to the group is still important to boys and girls. Gradually, they begin to crave identity and are no longer satisfied to be like their peers in every respect, as they were earlier.

However, the ambiguous status of the adolescent in the Indian culture of today presents a dilemma that greatly contributes to the adolescent “identity crisis” or the problem of ego identity. The ways adolescents try to establish themselves as individuals is by the use of status symbols in the form of cars, clothes, hand-held music systems, mobile phones, net chat and other readily observable material possessions. They hope, in this way, to attract attention to them and to be recognized as individuals while, at the same time, maintaining their identity with the peer group.

Adolescence is a Dreaded Age:
Many popular beliefs about adolescents have definite evaluative connotations and unfortunately, many of them are negative. Acceptance of the cultural stereotype of teenagers as sloppy, unreliable individuals who are inclined toward destructiveness and antisocial behavior has led many adults who must guide and supervise the lives of young adolescents to dread this responsibility and to be unsympathetic in their attitudes toward, and treatment of, normal adolescent behavior.

Popular stereotypes have also influenced the self-concepts and attitudes of adolescents toward themselves. The cultural stereotypes have also functioned as mirrors held up to the adolescent by society reflecting an image of himself that the adolescent gradually comes to regard as authentic and according to which he shapes his behavior. The acceptance of this stereotype and the belief that adults have poor opinions of them make the transition into adulthood difficult. By so doing, it leads to much friction with their parents and places a barrier between them and their parents which prevents them from turning to their parents for help in solving their problems.

Adolescence is a Time of Unrealism:
Adolescents have a tendency to look at life through rose-tinted glasses. They see themselves and others as they would like them to.be rather than as they are. This is especially true of adolescent aspirations. These unrealistic aspirations, not only for themselves but also for their families and friends, are, in part, responsible for the heightened emotionality characteristic of early adolescence.

The more unrealistic their aspirations are, the more angry, hurt, and disappointed they will be when they feel that others have let them down or that they have not lived up to the goals they set for themselves. With increased personal and social experiences and with increased ability to think rationally, older adolescents see themselves, their families and friends, and life in general in a more realistic way: As a result, they suffer less from disappointment and disillusionment than they did when they were younger.

This is one of the conditions that contribute to the greater happiness of the older adolescent. As adolescence draws to a close, it is not uncommon for both boys and girls to be plagued by over-idealism of the single, carefree life that they will soon give up as they achieve the status of adults. Feeling that this period of their lives is happier than what they will face in adulthood, with its demands and responsibilities, there is a tendency to glamorize adolescence and to feel that a happy, carefree age has been lost forever.

Adolescence is the Threshold of Adulthood:
As adolescents approach legal maturity, they are anxious to shed the stereotype of teenagers and to create the impression that they are near adults. Dressing and acting like adults, are hot always enough. So, they begin to concentrate on behavior that is associated with the adult status-smoking, drinking, using drugs and engaging in sex, for example. They believe that this behavior will create the image they desire.

Question 5:
Developmental tasks of adolescence.
Answer:
All the developmental tasks of adolescence are focused on overcoming childish attitudes and behavior patterns and preparing for adulthood. The developmental tasks of adolescence require a major change in the child’s habitual attitudes and patterns of behavior. Consequently, few boys and girls can be expected to master them during the years of early adolescence. This is especially true of late maturers.

The most that can be hoped is that the young adolescent will lay the foundations on which to build adult attitudes and behavior patterns. A brief survey of the important developmental tasks of adolescence will serve to illustrate the extent of the changes that must be made and the problems that arise from these changes.
Fundamentally, the necessity for mastering the developmental tasks in the relatively short time that adolescents have, as a result of lowering the age of legal maturity to eighteen, is the reason for much of the stress that plagues many adolescents.

It may be difficult for adolescents to accept their physiques if, from earliest childhood, they have a glamorized concept of what they wanted to look like when they are grown up. It takes time to revise this concept and to learn ways to improve their appearance so that it will conform more to their earlier ideals. Acceptance of the adult-approved sex role is not too difficult for boys; they have been encouraged in this direction since early childhood.

But for girls, who as children were permitted or even encouraged to play an egalitarian role, learning what the adult-approved feminine role is and accepting it is often a major task requiring many years of adjustment. Because of the antagonism toward members of the opposite sex that often develops during late childhood and puberty, learning new relationships with members of the opposite sex actually means starting from scratch to discover what they are like and how to get along with them. Even developing new, more mature relationships with age-mates of the same sex may not be easy.

Achieving emotional independence from parents and other adults would seem, for the independence-conscious adolescent, to be an easy developmental task. However, emotional independence is not the same as independence of behavior. Many adolescents who want to be independent want and need the security that emotional dependence on their parents or some other adults gives. This is especially true for adolescents whose status in the peer group is insecure or who lack a close tie with a member of the peer group.

Economic independence cannot be achieved until adolescents choose an occupation and prepare for it. If they select an occupation that requires a long period, of training, there can be no assurance of economic independence even when they reach legal adulthood. They may have to remain economically dependent for several years until their training for their chosen vocations has been completed.

Schools and colleges put emphasis on developing intellectual skills and concepts necessary for civic competence. However, few adolescents are able to use these skills and concepts in practical situations. Those who are active in the extracurricular affairs of their schools and colleges get such practice, but those who are not active in this way because they must take after-school jobs or because they are not accepted by their peers are deprived of this opportunity.

Schools and colleges also try to build values that are in harmony with those held by adults; parents contribute to this development. When, however, the adult-fostered values clash with peer values, adolescents must choose the latter if they want the peer acceptance on which their social life depends. Closely related to the problem of developing values in harmony with those of the adult world the adolescent is about to enter is the task of developing socially responsible behavior.

Most adolescents want to be accepted by their peers, but they often gain this acceptance at the expense of behavior that adults consider socially irresponsible. If, for example, it is the “thing to do” to cheat or to help a friend during an examination, the adolescent must choose between adult and peer standards of socially responsible behavior. The trend toward earlier marriages has made preparation for marriage one of the most important developmental tasks of the adolescent years.

While the gradual relaxing of social taboos on sexual behavior has gone a long way toward preparing adolescents of today for the sexual aspects of marriage, they receive little preparation-at home, in school, or in college-for the other aspects of marriage and even less preparation for the duties and responsibilities of family life. This lack of preparation is responsible for one of the major pieces of “unfinished business” which the adolescent carries into adulthood.

Question 6:
Physical changes during adolescence.
Answer:
Growth is not complete when puberty ends,.nor is it entirely complete at the end of early adolescence. However, there is a slowdown of the pace of growth and there is more marked internal than external development. This cannot be so readily observed or identified as growth in height and weight or the development of secondary sex characteristics.

Variations in Physical Changes:
Like all ages, there are individual differences in physical changes. Sex differences are especially apparent. Even though boys start their growth spurt later than girls, their growth continues longer, with the result that, at maturity, they are usually taller than girls. Because boys’ muscles grow larger than girls’ muscles, at all ages after puberty boys surpass girls in strength, and this superiority increases with age.

Individual differences are also influenced by age of maturing. Late maturers tend to have slightly broader shoulders than those who mature early. The legs of early-maturing boys and girls tend to be stocky; those of late maturers tend to be more slender. Early-maturing girls weigh more, are taller, and have greater weight for their height than do late-maturing girls.

Effects of Physical Changes:
As physical changes slow down, the awkwardness of puberty and early adolescence generally disappear. This is because older adolescents have had time to gain control of their enlarged bodies. They are also motivated to use their newly acquired strength and this further helps them to overcome any awkwardness that appeared earlier.

Because strength follows growth in’ muscle size, boys generally show their greatest increase in strength after age fourteen, while girls show improvement up to this age and then lag, owing more to changes in interests than to lack of capacity. Girls generally attain their maximum strength at about seventeen, while boys do not attain their maximum strength until they are twenty-one or twenty-two.

Concerns about Physical Changes:
Few adolescents experience body-cathexis or satisfaction with their bodies. However, they do experience more dissatisfaction with some parts of their bodies than with other parts. This failure to experience body-cathexis is one of the causes of unfavorable self¬concepts and lack of self-esteem during the adolescent years. Some of the concerns adolescents have about their bodies are carry-overs of concerns they experienced during puberty and which, in the early years of adolescence, are based on conditions that still prevail.

Concern about normalcy, for example, will persist until the physical changes on the surface of the body have been completed and adolescents can be sure that their bodies conform to the norms for their sex groups. Similarly, concern about sex appropriateness, so all-pervading in puberty, continues until the primary and secondary sex characteristics have completed their growth and development and, thus, give adolescents an opportunity to. see if their bodies conform to the cultural standard of sex-appropriateness.

Awareness of social reactions to different body builds leads to concern in adolescents whose changing bodies fail to conform to the culturally approved standards. Knowing that social reactions to endomorphic builds in both boys and girls are less favorable than they are to ectomorphic and mesomorphic -builds leads to concern on the part of adolescents whose body builds tend toward endomorphy. For many girls, menstruation is a serious concern. This is because they suffer physical discomforts such as cramps, weight gain, headaches, backaches, swollen ankles and breast tenderness and experience emotional changes, such as mood swings, depression, restlessness, depression, and a tendency to cry without apparent reason.

Because menstruation is commonly referred to as “the curse,” it is not surprising that this unfavorable social reaction will color girls’ attitudes. Furthermore, knowing that boys do not experience any such form of physical discomfort also colors girls’ attitudes – unfavorably and encourages them to believe that they are martyrs.
Acne and other skin eruptions are a source of concern to both boys and girls. With the increase in the severity of acne, there is an increase in concern.

This concern is often as great for boys, as for girls because they realize that acne mars their chances for physical attractiveness and because they cannot use cosmetics to cover it up as girls can. The tendency toward obesity that plagues most pubescent boys and girls continues to be a source of concern during the early adolescent years. In most cases, however, with increase in height and with efforts to control their appetites and the eating of “junk food,” older adolescents start to slim down and look less obese than they did during the puberty fat period.

In addition, careful selection of clothing helps to create tb; illusion that they are more slender than they actually are. It is unusual for adolescents, boys or girls, not to be concerned about their physical attractiveness. Few are satisfied with their appearance and many are concerned about what they can do to improve it. The reason for concern comes from the realization of the role attractiveness plays in social relationships. Adolescents realize, even more than children do, that people treat those who are attractive more favorably than they do those who are less attractive. They are also aware of the important role attractiveness -plays in the choice for leadership.

Consequently, when they feel that they are less attractive than they had hoped to be when their growth was complete or nearly complete, they are concerned about what they can do to improve their looks. Few adolescents escape being “looks-conscious” to the point where they spend proportionally more time and thought on how to improve their looks than most adults consider justified.

Question 7:
Hypothetico-Deductive Reasoning.
Answer:
At adolescence, young people first become capable of hypothetico-deductive reasoning; When faced with a problem, they start with a general theory of all possible factors that might affect the outcome and deduce from it specific hypotheses (or predictions) “ about what might happen. Then they test these hypotheses in an orderly fashion to see which ones work in the real World. Notice how this form of problem-solving begins with possibility and proceeds to reality. In contrast, concrete operational children start with reality-with the most obvious predictions about a situation. When these are not confirmed, they cannot think of alternatives and fail to solve the problem.

Adolescents’ performance on Piaget’s famous pendulum problem illustrates this new approach. Suppose we present several school-age children and adolescents with strings of different lengths, objects of different weights to attach to the strings and a bar from which to hang the strings. Then we ask each of them to figure out what influences the speed with which a pendulum swings through its arc.
Formal operational adolescents come up with four hypotheses:

  • the length of the string,
  • the weight of the object hung on it,
  • how high the object is raised before it is released and
  • how forcefully the object is pushed.
    Then, by varying one factor at a time while holding all the others constant, they try out each possibility. Eventually, they discover that only string length makes a difference.

In contrast, concrete operational children experiment unsystematically. They cannot separate the effects of each variable. They may test for the effect of string length without holding weight constant, comparing, for example, a short, light pendulum with a long, heavy one. Also, school-age children fail to notice variables that are not immediately suggested by the concrete materials of the task-the height at which and forcefulness with which the pendulum is released.

Question 8:
What is Propositional Thought in adolescence?
Answer:
A second important characteristic of the formal operational stage is propositional thought. Adolescents can evaluate the logic of propositions without referring to real-world circumstances. In contrast, children can evaluate the logic of statements only by considering them against concrete evidence in the real world. In a study of propositional reasoning, a researcher showed children and adolescents a pile of tokens (plastic round coins) and asked whether statements about the tokens were t true, false, or uncertain.

In one condition, the researcher hid a token in her hand and presented the following propositions: “Either the token in my hand is green or it is not green:’ “The token in my hand is green and it is not green.” In another condition, the experimenter held either a red or a green token in full view and made the same statements.
School-age children focused on the concrete properties of the tokens. When the token was hidden from view, they replied that they were uncertain about both statements. When it was visible, they judged both statements to be true if the token was green and false if it was red.

In contrast, adolescents analyzed the logic of the statements. They understood that the “either-or” statement is always true and the “and” statement is always false, regardless of the poker token’s color. Although Piaget did not view language as playing a central role in children’s cognitive development, he acknowledged it is more important in adolescence. Abstract thought requires language-based systems of representation that do not stand for real things, such as those in higher mathematics. Secondary school students use these systems in algebra and geometry.

Question 9:
Social changes during adolescence.
Answer:
The most difficult developmental tasks of adolescence relates to social adjustments. These adjustments must be made to members of the opposite sex in a relationship that never existed before and to adults outside the family and school environments. To achieve the goal of adult patterns of socialization, the adolescent must make many new adjustments* the most important and, in many respects, the most difficult of which are those to the increased influence of the peer group, changes in social behavior, new social groupings, new values in friendship selection, new values in social acceptance and rejection and new values in the selection of leaders.

Increased Peer-Group Influence:
Because adolescents spend most of their time outside the home with members of the peer group, it is understandable that peers would have a greater influence on adolescent attitudes, speech, interests, appearance and behavior than the family has. Most adolescents, for example, discover that if they wear the same type of clothes as popular group members wear, their chances of acceptance are enhanced. Similarly, if members of the peer group experiment with alcohol, drugs, or tobacco, adolescents are likely to do the same, regardless of how they feel about these matters.

As adolescence progresses, peer-group influence begins to wane. There are two reasons for this. First, most adolescents want to become individuals in their own right and to be recognized as such. The search for identity discussed earlier in this chapter, weakens the influence of the peer group on the adolescent. The second reason for waning of peer-group influence is the result of the adolescent’s choice of peers as companions.

No longer are adolescents interested in large group activities, as was true during their childhood days. In adolescence, there is a tendency to narrow down friendships to smaller numbers though most adolescents want to belong to larger social groups for social activities. Because these social activities are less meaningful to adolescents than close, personal friendships, the influence of the larger social group becomes less pronounced than the influence of friends.

Changes in Social Behavior:
Of all the changes that take place in social attitudes and behavior, the most pronounced is in the area of heterosexual relationships. In a short period of time, adolescents make the radical shift from disliking members of the opposite sex to preferring their companionship to that of members of their own sex. Social activities, whether with members of the same sex or with the Opposite sex, usually reach their peak during the high-school years. As a result of broader opportunities for social participation, social insight improves among older adolescents. They are now able to judge members of the opposite sex as well as members of their own sex better than they could when they were younger. As a result, they make better adjustments in social situations and they quarrel less.

The greater the social participation of adolescents, the greater their social competency, as seen in their ability to dance, to canyon conversations, to play sports and games that are popular with agemates and to behave correctly in different social situations. As a result, they gain self-confidence which is expressed in poise and ease in social situations. Whether prejudice and discrimination will increase or decrease during adolescence will be greatly influenced by the environment in which adolescents find themselves and by the attitudes and behavior of their friends and associates.

Because adolescents, as a group, tend to be more “choosey” in the selection of associates and friends than they were as children, they find adolescents of different racial, religious, or socioeconomic backgrounds less congenial than those with similar backgrounds. However, they are more likely to ignore those they find uncongenial than to treat them in a way that expresses their feelings of superiority, as older children do.

New Social Groupings:
The gangs of childhood gradually break up at puberty and during early adolescence as the individual’s interests shift from the strenuous play activities of childhood tb the less strenuous and more formal social activities of adolescence. In their place come new social groupings. The social groupings Of boys as a rule are larger and more loosely knit while those of girls are smaller and more sharply defined.
The most common social groupings during adolescence are described below:

  • Close Friends:
    The adolescent usually has two or three close friends, or confidants. They are of the same sex and have similar interests and abilities. Close friends have a marked influence on one another, though they may quarrel occasionally.
  • Cliques:
    Cliques are usually made up of groups Of close friends. At first they consist of members of the same sex, but later include both boys and girls.
  • Crowds:
    Crowds made up of cliques and groups of close friends, develop as interest in parties and dating grows. Because crowds are large, there is less congeniality of interest among the members and thus a greater social distance between them.
  • Organized Groups:
    Adult-directed youth groups are established by schools and community organizations to meet the social needs of adolescents who belong to no cliques or crowds. Many adolescents who join such groups feel regimented and lose interest in them by the time they are sixteen or seventeen.

Gangs:
Adolescents who belong to no cliques or crowds and who gain little satisfaction from organized groups may join a gang. Gang members are usually of the same sex and their main interest is to compensate for peer rejection through antisocial behavior. There are changes in some of these social groupings as adolescence progresses. Interest in organized groups, whose activities are planned and to a large extent controlled by adults, wanes rapidly as independence-conscious adolescents present being told what to do. Only if the control of the activities of these groups is turned over to them, with minimum of adult advice and interference, will interest continue. Crowds tend to disintegrate in late adolescence and are replaced by loosely associated groups of couples. This is especially true of adolescents who go to work at the completion of high school.

At work they are in contact with people, of all ages, most of whom have friends and families of their own outside their jobs. Unless noncollege older adolescents have friends from their school days who live and work near enough to make contacts possible they may find themselves limited to a few friends connected with their work and out of touch with any group large enough to form a crowd. By contrast, the influence of the gang tends to increase as adolescence progresses. This influence is often expressed in violent behavior committed by gang members.

Adolescents want as friends those whose interests and values are similar to theirs, who understand them and make them feel secure and in whom they can confide problems and discuss matters they feel they cannot share with parents or teachers. Most adolescents claim they want “someone to be trusted, someone to talk to and someone who is dependable”. Because of these changed values, childhood friends will not necessarily be friends in adolescence. Nor are adolescents interested only in friends of their own sex. Interest in the opposite sex becomes increasingly stronger as adolescence progresses. As a result, by the end of adolescence, there is often a preference for friends of the opposite sex, though both boys and girls continue to have a few intimate friends of their own sex with whom they associate constantly.

Question 10:
What is Erikson’s theory: Identity versus Identity confusion?
Answer:
Erikson was the first to recognize identity as the major or personality achievement of adolescence and as a crucial step toward becoming a productive, happy adult. Constructing an identity involves defining who you are, what you value and the directions you choose to pursue in life. One expert described it as an explicit theory of oneself as a rational agent-one who acts on the basis of reason, takes responsibility for those actions, and can explain them.

This search for what is true and real about the self is the driving force behind many new commitments to sexual orientation; a vocation; interpersonal relationships; community involvement; ethnic group membership and moral, political, religious and cultural ideals. Erikson called the psychological conflict of adolescence identity versus identity confusion. Successful outcomes of earlier stages paves the way to its positive resolution.

Young people who reach adolescence with a weak sense of trust have trouble finding ideals to have faith in. Those with little autonomy or initiative do not engage in the active exploration required to choose among alternatives. And those who lack a sense of industry fail to select a vocation that matches their interests and skills.
Although the seeds of identity formation are planted early, not until adolescence do young people become absorbed in this task.

According to Erikson, in complex societies, teenagers experience an identity crisis—a temporary period of confusion and distress as they experiment with alternatives before settling on values and goals. Adolescents who go through a process of inner soul-searching eventually arrive at a mature identity. They sift through characteristics that defined the self in childhood and combine them with new commitments.

Then they mold these into a solid inner core that provides a sense of stability as they move through different roles in daily life. Once formed, identity continues to be refined in adulthood as people reevaluate earlier commitments and choices. Current theorists agree with Erikson that Qing of values, plans and priorities is necessary for a mature identity, but they no longer refer to this process as a “crisis”. For some young people, identity development is traumatic and disturbing, but for most it is not.

Exploration better describes the typical adolescent’s gradual, uneventful approach to identity formation. By trying out various life possibilities and moving toward making enduring decisions, young people forge an organized self-structure. Erikson described the negative outcome of adolescence as identity confusion. Some young people appear shallow and directionless, either because earlier conflicts have been resolved negatively or because society restricts their choices to ones that do not match their abilities and desires.

As a result, they are unprepared for the psychological challenges of adulthood. For example, individuals find it difficult to risk the self-sharing involved in
Erikson’s young adult stage-intimacy-if they do not have a firm sense of self (an identity) to which they can return.

Question 11:
What is adulthood?
Answer:
Introduction:
The word adult comes from the same Latin verb as the term adolescence-adolescere which means “to grow to maturity!” However, the word adult is derived from the past participle of the verb-adults -which means “grown, to full size and strength” or “matured.” Adults are, therefore, individuals who have completed their growth and are ready to assume their status in society along with other adults.

Various cultures have different ages at which children reach the adult status or the age of legal maturity, in most of the older cultures, they reached this status when their puberty growth was complete or nearly complete and when their sex organs had developed to the point where they were capable of procreation. Until recently, children were not considered legally adults until they reached the age of twenty-one years.

Question 12:
Characteristics of early adulthood.
Answer:
Early adulthood is a period of adjustments to new patterns of life and new social expectations. The young adult is expected to play new roles, such as that of spouse, parent, and breadwinner, and to develop new attitudes, interests and values in keeping with these new roles. These adjustments make early adulthood a distinctive period in the life span and also a difficult one.

It is especially difficult because, until now, most boys and girls have had someone’s parents, teachers, friends or others to help them make the adjustments they are faced with. Now, as adults, they are expected to make these adjustments for themselves. To avoid being considered “immature,” they hesitate to turn to others for advice and help when they find the adjustments too difficult to cope with successfully alone.

Early Adulthood is the “Settling-down Age”:
Childhood and adolescence are the periods of “growing up” and adulthood is the time for “settling down:” In past generations, it was assumed that when boys and girls reached the age of legal maturity, their days of carefree freedom were over and the time had come to settle down and assume the responsibilities of adult life. That meant settling into a line of work that would be the man’s career for the rest of his life, while the young woman was expected to assume the responsibilities of homemaker and mother- responsibilities that would be hers for the remainder of her life.

Today, it is recognized that “settling down” too early is often laying the foundations for discontent because of too early choices of careers or life-mates. Consequently, many young men try out different lines of work to see which meets their needs best and which will bring them lifelong satisfaction. While trying out different lines of work, many young men also try out different women to find out if they have the qualities they want for a lifelong spouse.

This trying out of different life patterns and different individuals to share their life patterns takes time. Consequently, young adults today usually start to settle down late than their parents did and much later than their grandparents did. The average adult of today has chosen a lifestyle and an individual to share that lifestyle by the early thirties, though many do so before then.

When adults of today start to settle down depends upon two factors. First, how soon they are able to find a lifestyle that meets their needs then and which they believe will meet their needs throughout life. A woman, who, since the days she played with dolls always wanted to be a wife and mother, will not need long after completing her education to choose these occupations as her life roles.

Similarly, a man who never wanted to be anything but a doctor will not have to go through the trial-and-error process to find a career that meets his needs as will his friends who frankly claimed, as Ijoys, that they did not know what they wanted to do when they reached the end of their schooling.

Early Adulthood Is the “Reproductive Age”:
Parenthood is one of the most important roles in the lives of most young adults. Those who were married during the latter years of adolescence concentrate on the role of. parenthood during their twenties and early thirties; some become grandparents before early adulthood ends. Those who do not marry until they have completed their education or have started their life careers do not become parents until they feel they can afford to have a family. This is often not until the early thirties. Also, if women want to pursue careers after marriage, they may put off having children until their thirties. For them, then, only the last decade of early adulthood is the “reproductive age.” For those who begin to have children early in adulthood or even in the closing years of adolescence and have large families, all of early adulthood is likely to be a reproductive age.

Early Adulthood is a “Problem Age”:
The early adult years present many new problems, different in their major aspects, from the problems experienced in the earlier years of life. With the lowering of the age of legal maturity to eighteen years, young adults have been confronted with many problems they are totally unprepared to cope with. While they are now able to vote, to own property, to marry without parental consent, and to do many things young people could not do when the age of legal maturity was twenty-one years, there is no Q about the fact that “this new-found freedom is creating unforeseen problems for the youthful adults and often for their parents, too”.There are many reasons why adjustment to the problems of adulthood is so difficult.

Three are especially common. First, very few young people have had any preparation for meeting the types of problems they are expected to cope with as adults. Education in high school and college provides only limited training for jobs, and few schools or colleges give courses in the common problems of marriage and parenthood. Even those who have had babysitting experience have limited preparation for parenthood because most babysitters are hired only for short times when parents are out of the home and their major responsibility is to keep the children safe and happy until the parents return. Second, just as trying to learn two or more skills simultaneously usually results in not learning any one of them well, so trying to adjust to two or more new roles simultaneously usually results in a poor adjustment to all of them.

It is difficult for a young adult to deal with the choice of a career and the choice of a mate simultaneously. Similarly, adjustment to marriage and parenthood makes it difficult for young adults to adjust to work if they marry while they are still students. Third and perhaps most serious of all, young adults do not have help in meeting and solving the problems that they had when they were younger. This is partly their own fault and partly that of their parents and teachers. Most young adults are too proud of their new status to admit that they cannot cope with it. So, they do not seek advice and help in meeting the problems this new status gives rise to. Similarly, most parents and teachers, having been rebuffed by adolescents who claimed they were capable of handling their own affairs, hesitate to offer help unless they are specifically asked to do so. That is why, as was stressed earlier, the shortening of adolescence has made the transition to adulthood especially difficult.

Early Adulthood is a Period of Emotional Tension:
When people are trying to get the lay of a new land in which they find themselves, they are likely to be emotionally upset. By the early or mid-thirties, most young adults have solved their problems well enough to become emotionally stable and calm. Should the heightened emotionality characteristic of the early years of adulthood persist into the thirties, it suggests that adjustments to adult life have not been satisfactorily made. When emotional tension persists into the thirties, it is generally expressed in worries. What young adults worry about will depend on what adjustment problems they are facing at the time and how much success or failure they are experiencing in meeting these problems. Their worries may be mainly concentrated on their work, because they feel they are not advancing as rapidly as they had hoped to, or their worries may be concentrated on marital or parenthood problems. When adults feel that they have not been able to cope with the problems in the major areas of their lives, they are often so emotionally disturbed that they contemplate or attempt suicide.

Early Adulthood is a Period of Social Isolation:
With the end of formal education and the entrance into the adult life pattern of work and marriage, associations with the peer groups of adolescents wane and, with them, opportunities for social contacts outside the home. As a result, for the first time since babyhood, even the most popular individual is likely to experience social isolation, or what Erikson has referred to as an “isolation crisis”. Many young adults, having become accustomed throughout childhood and adolescence to depending on peers for companionship, experience loneliness when responsibilities at home or at work isolate them from groups of their peers. Those who were most popular during their school and college days and who devoted much of their time to peer activities, find the adjustment to social isolation in adulthood especially difficult.

Whether the loneliness that comes from this isolation will be temporary or persistent depends on how quickly and how satisfactorily the young adult can establish new social contacts to replace those of school and college days. Isolation is intensified by a competitive spirit and a strong desire, to rise on the vocational ladder. To achieve success, they must compete with others thus replacing the friendliness of adolescence with the competitiveness of the successful adult-and they must also devote most of their energies to their work, which leaves them little time for the socialization that leads to close relationships. As a result, they become self-centered, which contributes to loneliness.

Early Adulthood is a time of commitments:
As young adults change their role from that of student and dependent, Characteristic of adolescence, to that of independent adult, they establish new patterns of living, assume new responsibilities and make new commitments. While these new patterns of living, new responsibilities and new commitments may change later, they form the foundations on which later patterns of living, responsibilities, and commitments will be established.

Early Adulthood is often a period of Dependency:
In spite of achieving the status of legal adulthood at age eighteen,- with the independence this status carries, many young adults are partially or totally dependent on others for varying lengths of time. This dependency may be on parents; on the educational institution they attend on part or total scholarship, or on the government for loans to finance their education.

Question 13:
Concepts of Adult Sex Roles Traditional Concepts.
Answer:

Traditional Concepts:
Traditional concepts of sex roles emphasize a prescribed pattern of behavior, regardless of individual interests or abilities. They emphasize masculine supremacy and intolerance toward any trait that hints of femininity or any work that is considered “woman’s work.”

  • Men:
    Outside the home, the man holds positions of authority and prestige in the social and business worlds; in the home, he is the wage earner, decision maker, adviser and disciplinarian of the children, and model of masculinity for his sons.
  • Women:
    Both in the home and outside, the role of the woman is other-oriented in that she gains fulfillment by serving others. She is not expected to work outside the home except in cases of financial necessity and then she does only work that serves others, such as nursing, teaching, or secretarial work.

Egalitarian Concepts:

Egalitarian concepts of sex roles emphasize the individuality and the egalitarian status of men and women. Roles should lead to personal fulfillment and not be considered appropriate for only one sex.

  • Men:
    In the home and outside, the man works with the woman in a companionship relationship; He does not feel “henpecked” if he treats his wife as art equal, nor does he feel ashamed if she has a more prestigious or remunerative job than he does.
  • Women:
    Both in the home and outside, the woman is able to actualize her own potential. She does not feel guilty about using her abilities and training to give her satisfaction, even if this requires employing someone else to take care of the home and children.

Erikson’S Theory: Intimacy Versus Isolation:

Erikson’s contributions have energized the study of adult personality development. His vision has influenced all contemporary theories. According to Erikson, adults move through three stages, each bringing both opportunity and risk-”a turning point for better or worse”. The psychological conflict of early adulthood is intimacy versus isolation, reflected in the young person’s thoughts and feelings about making a permanent commitment to an intimate partner.
In his definition of intimacy, Erikson stated that it should include
1. Mutuality of orgasm
2. with a loved partner
3. of the other sex
4. With whom one is able and willing to share a mutual trust
5. and with whom one is able and willing to regulate the cycles of work, procreation, and recreation.
6. so as to secure to the offspring, too, all the stages of satisfactory development Erikson pointed out, that sexual intercourse should not be assumed to be the most important aspect of intimacy between individuals. He was speaking here of far more than sexual intimacy. He was talking about the ability to relate one’s deepest hopes and fears to another person and to accept another’s need for intimacy in turn.

Those who have achieved the stage of intimacy are able to commit themselves to concrete affiliations and partnerships with others and have developed the “ethical strength to abide by such commitments, even though they may call for significant sacrifices and compromises”. This leads to solidarity between partners. Erikson was found quoting Freud’s response when asked what he thought a normal person should be able to do well: “Lieben und arbiten “to love and. to work.” To Freud, then sharing responsibility for mutual achievement and the loving feelings that result from them are the essence of adulthood. Erikson fully agreed with this.

Thus when Freud uses the term genitality to describe this same period he does not merely mean sexual intercourse; he is referring rather to the ability to share one’s deeply held values, needs, and secrets with another through the generosity that is so important in intimacy. The counterpart of intimacy is distantiation. This is the readiness all of us have to distance ourselves from others when we feel threatened by their behavior. Distantiation is the cause of most prejudices and discrimination. Propaganda efforts mounted by countries at war are examples of attempts to increase distantiation. It is what leads to isolation.

Most young adults vacillate between their desires for intimacy and their need for distantiation. They need social distance because they are not sure of their identities. They are always vulnerable to criticism, and since they can’t be sure whether the criticisms are true or not, they protect themselves by a “lone wolf ’ stance. Although intimacy may be difficult for some males today, Erikson believed that it used to be even more difficult for females.

“All this is a little more complicated with women, because women, at least in yesterday’s cultures, had to keep their identities incomplete until they knew their man”. Now that less emphasis occurs in the female gender role on getting married and pleasing one’s husband, and more emphasis is on being true to ones own identity, Erikson believed that both sexes have a better chance of achieving real intimacy.

Erikson believed that successful resolution of intimacy versus isolation prepares the individual for the middle adulthood stage, which focuses on Generativity-caring for the next generation and helping to improve society. In sum, both intimacy and Generativity emerge in early adulthood, with shifts in emphasis that differ among young people.

Question 14:
Middle Adulthood is a Time of Stress.
Answer:
Radical adjustments to changed roles and patterns of life, especially when accompanied by physical changes, always tend to disrupt the individual’s physical and psychological homeostasis and lead to a period of stress-a time when a number of major adjustments must be made in the home, business, and social aspects of their lives.
Categories of Stress in Middle Adulthood are:

  • Somatic stress, which is due to physical evidence of aging.
  • Cultural stress, stemming from the high value placed on youth, vigor, and success by the cultural group.
  • Economic stress, resulting from the financial burden of educating children and providing status symbols for all family members.
  • Psychological stress, which may be the result of the death of a spouse, the departure of children from the home, boredom with marriage, or a sense of lost youth and approaching death.

Most women experience a disruption in homeostasis during their forties, when normally they go through menopause and their last children leave home, thus forcing them to make radical readjustments in the pattern of their entire lives. For men, by contrast, the climacteric comes later-generally in the fifties-as does the imminence of retirement with its necessary role changes.

Long Questions With Answers

Question 1.
Describe the period of infancy.
Answer:
Infancy, or the period of the newborn, is, according to standard dictionaries, the beginning or the early period of existence as an individual rather than as a parasite in the mother’s body. Dictionaries also define an infant as a child in the first period of life.

According to Legal, standards, an infant is an individual who is a minor until reaching the age of legal maturity, which, in America today, is eighteen years. According to medical terminology, an infant is a young child, but no specific age limits are placed on when the individual ceases to be an infant and becomes a child.Many psychologists use the word infant in much the same way. as members of the medical profession do and, like them, fail to set an age limit on infancy.

This gives the period an ambiguous status in its lifespan. The word infant suggests extreme helplessness, and it will be limited to the first few weeks of life. During this period, the newborn’s complete helplessness gradually gives way to increasing independence. Further toddlerhood occupies the first two years of life following the brief two-week period of infancy. During the toddlerhood months, there is a gradual but pronounced decrease in helplessness. This does not mean that helplessness quickly disappears and is replaced by independence.

Instead, it means that every day, week and month the individual becomes more independent so that, when toddlerhood ends with the second birthday, the individual is a quite different person than when toddlerhood began. Because “baby” suggests too many people a helpless individual, it is becoming increasingly common to apply the label toddler to the individual during the second year of toddlerhood. A toddler is a baby who has achieved enough body control to be relatively independent.

Characteristics Of Infancy:

Each period in the life span is characterized by certain developmental phenomena that distinguish it from the periods that precede and follow it. While some of these phenomena may be associated with other periods, they appear in a distinctive form during infancy. Following are the five most important characteristics of this period.

Infancy Is the Shortest of All Developmental Periods:
Infancy begins with birth and ends when the infant is approximately two weeks old, by far the shortest of all developmental periods. It is the time when the fetus must adjust to life outside the uterine walls of the mother where it has lived for approximately nine months. According to medical criteria, the adjustment is completed with the fall of the umbilical cord from the navel; according to physiological criteria, it is completed when the infant has regained the weight lost after birth and according to psychological criteria.It is completed when the infant begins to show signs of developmental progress in behavior. Although most infants complete this adjustment in two weeks or slightly less, those whose birth has been difficult or premature require more time.
In spite of its shortness, infancy is generally subdivided into two periods: the period of the Partunate and the period of the neonate.

Period of the Partunate :
(from birth to fifteen to thirty minutes after birth): This period begins when the fetal body has emerged from the mother’s body and lasts until the umbilical cord has been cut and tied. Until this is done, the infant continues to be a parasite and makes no adjustments to the postnatal environment the environment outside the mother’s body.

Period of the Neonate :
(from the cutting and tying of the umbilical cord to approximately the end of the second week of postnatal life): The infant is now a separate, independent individual and is no longer a parasite. During this period, the infant must make adjustments to the new environment outside the mother’s body. Even in difficult births, it seldom takes more than forty-eight hours for the fetus to emerge from the mother’s body. By contrast, it requires approximately two weeks adjusting to the new environment outside the mother’s body.

Infancy Is a Time of Radical Adjustments :
Although the human life span legally begins at the moment of birth, birth is merely an interruption of the developmental pattern that started at the moment of conception. It is the graduation from an internal to an external environment. Like all graduations, it requires adjustments on the individual’s part. It may be easy for some infants to make these adjustments but so difficult for others that they will fail to do so. Miller has commented, “In all the rest of his life, there will never be such a sudden and Complete change of locale”.

Infancy Is a Plateau in Development:
The rapid growth and development which took place during the prenatal period suddenly come to a stop with birth. In fact, there is often a slight regression, such as loss of weight and a tendency to be less strong and healthy than at birth. Normally this slight regression lasts for several days to a week, after which the infant begins to improve. By the end of the infancy period, the infant’s state of development is usually back to where it was at the time of birth. The halt in growth and development, characteristic of this plateau, is due to the necessity for making radical adjustments to the postnatal environment.

Once these adjustments have been made, infants resume their growth and development. While a plateau in development during infancy is normal, many parents, especially those of firstborn children, become concerned about it and fear that something is wrong with their child. Consequently, the infancy plateau may become a psychological hazard, just as it is a potential physical hazard.

Infancy Is a Preview of Later Development :
It is not possible to predict with even reasonable accuracy what the individual’s future development will be on the basis of the development apparent at birth. However, the newborn’s development provides a clue as to what to expect later on.

Infancy Is a Hazardous Period :
Infancy is a hazardous period, both physically and psychologically. Physically, it is hazardous because of the difficulties of making the necessary radical adjustments to the totally new and different environment. The high infant mortality rate is evidence of this. Psychologically, infancy is hazardous because it is the time when the attitudes of significant people toward the infant are crystallized. Many of these attitudes were established during the prenatal period and may change radically after the infant is born, but some remain relatively unchanged or are strengthened, depending on conditions at birth and on the ease or difficulty with which the infant and the parents adjust.

Question 2.
How to do adjustments of infancy?
Answer:
Infants must make four major adjustments before they can resume their developmental progress. If they do not make them quickly, their lives will be threatened. While these adjustments are being made, there is no developmental progress. Instead, the infant remains on a plateau or may even regress to a lower stage of development, These adjustments are:

Temperature Changes:
There is a constant temperature of 100°F in the uterine sac, while temperatures in the hospital or home may vary from 60 to 70°F.

Breathing:
When the umbilical cord is cut, infants must begin to breathe on their own.

Sucking and Swallowing:
The infant must now get nourishment by sucking and swallowing, instead of receiving it through the umbilical cord. These reflexes are imperfectly developed at birth and the infant often gets less nourishment than is needed and thus loses weight.

Elimination:
The infant’s organs of elimination begin to work soon after birth; formerly, waste products were eliminated through the umbilical cord. Every newborn infant finds adjustment to postnatal life difficult at first. Some have trouble adjusting to temperature changes and develop colds, which may turn into pneumonia. Others find breathing difficult and must be given oxygen. Most choke when they attempt to suck and swallow and many regurgitate more than they are able to retain, in which case they get less nourishment than they need to grow or even to retain their birth weight. Few have any real trouble eliminating urine, but many have difficulties with fecal elimination.

Question 3.
What is Length of Gestation Period?
Answer:
The fourth condition that influences infants’ adjustments to postnatal life is the length of the gestation period. Very few infants are born exactly 280 days after conception. Those who arrive ahead of time are known as premature -often referred to in hospitals as “preemies”- while those who arrive late are known as postmature, or post-term babies.

Postmaturity occurs less often than in the past because it is now possible to induce labor when x-rays/scanning show that the fetus is large enough and well enough developed to adjust successfully to postnatal life. Induced labor is also used as a means of preventing possible birth complications and birth injuries, especially brain damage, which can result if the fetal head is allowed to grow too large.

It is now recognized that birth weight alone is not enough to determine prematurity. Instead, gestation age, body length, bone ossification, head circumference, irritability, reflex, nutritional state and neurological assessment are also used. When infants are 20 or more inches long and weigh 8 or more pounds, they are considered postmature. It they are less than 19 inches long and weigh 5 pounds 8 ounces or less, they are regarded as premature.

The more they deviate from the norm for their sex and racial group on the minus side, the more premature they are considered to be. On the other hand, the more they deviate on the plus side, the more postmature they are considered to be. Unless damaged at birth, the postmature infant usually adjusts more quickly and more successfully to the postnatal environment than the infant born at full term.

However, because the chances of birth damage increase as Postmaturity increases, the advantages that come from the speed and ease of adjustment are far outweighed by the possibilities of birth damage. Prematurely born babies usually experience complications in adjusting to the postnatal environment and these may have a serious effect on future adjustment. Furthermore, every difficulty that the normal, full-term infant faces in adjusting to the new environment is magnified in the case of the premature baby.

Question 4.
How the Toddlerhood is the True Foundation Age?
Answer:
While the whole of childhood, but especially the early years, are generally regarded as the foundation age, toddlerhood is the true foundation period of life because, at this time, many behavior patterns, many attitudes and many patterns of emotional expression are being established. Early scientific interest in the importance of these foundations came from the work of Freud, who maintained that personality maladjustments in adulthood had their origins in unfavorable childhood experiences.

Erikson also contended that “childhood is the scene of man’s beginning as man, the place where our particular virtues and vices slowly but clearly develop and make themselves felt.” According to Erickson, how babies are treated will determine whether they will develop “basic trust” or “basic distrust”-viewing the world as safe, reliable and nurturing or as full of threat, unpredictability and treachery. The first two years are critical in setting the pattern for personal and social adjustments. “Providing a rich social life for a twelve- to a fifteen-month-old child is the best thing you can do to guarantee a good mind”.

There are four reasons why foundations laid during the toddlerhood years are important. First, contrary to tradition, children do not outgrow undesirable traits as they grow older. Instead, patterns established early in life persist regardless of whether they are good or bad, harmful or beneficial. Second, if an undesirable pattern of behavior or unfavorable beliefs and attitudes have started to develop, the sooner they can be corrected the easier it will be for the child.

Third, because early foundations quickly develop into habits through repetition, they will have a lifelong influence on a child’s personal and social adjustments. And, fourth, because learning and experience play dominant roles in development, they can be directed and controlled so that the development will be along lines that will make good personal and social adjustments possible.

Question 5.
Notes on: Basic Trust versus Mistrust.
Answer:
Freud called the first year the oral stage and regarded gratification of the infant’s need for food and oral stimulation vital. Erikson accepted Freud’s emphasis on feeding, but he expanded and enriched Freud’s view. A healthy outcome during infancy, Erikson believed, does not depend on the amount of food or oral stimulation offered but rather on the quality of the caregiver’s behavior. A mother who supports her baby’s development relieves discomfort promptly and sensitively.

For example, she holds the infant gently during feedings, patiently waits until the baby has had enough milk, and weans when the infant shows less interest in the breast or bottle. Erikson recognized that no parent can be perfectly in tune with the baby’s needs. Many factors affect her responsiveness – feelings of personal happiness, current life conditions (for example, additional young children in the family) and culturally valued child-rearing practices.

But when the balance of care is sympathetic and loving, the psychological conflict of the year-basic trust versus mistrust is resolved on the positive side. The trusting infant expects the world to be good and gratifying, so he feels confident about venturing out and exploring it. The mistrustful baby cannot count on the kindness and compassion of others, so she protects herself by withdrawing from people and things around her.

Question 6.
Notes on: Autonomy versus Shame and Doubt.
Answer:
In the second year, during Freud’s anal stage, instinctual energies shift to the anal region of the body. Freud viewed toilet training, in which children must bring their anal impulses in line with social requirements, as crucial for personality development. Erikson agreed that the parent’s manner of toilet training is essential for psychological health. But he viewed it as only one of many important experiences for newly walking, talking toddlers. Their familiar refrains-” No!” and “Do it Myself’ -reveal that they have entered a period of budding selfhood.

Toddlers want to decide for themselves-not just in toileting but in other situations as well. The great conflict of toddlerhood, autonomy versus shame and doubt, is resolved favorably when parents provide young children with suitable guidance and reasonable choices. A self-confident, secure 2-year-old has been encouraged not just to use the toilet but to eat .with a spoon and to help pick up his toys. His parents do not criticize or attack him when he fails at these new skills. And they meet his assertions of independence with tolerance and understanding.

For example, they grant him an extra 5 minutes to finish his play before leaving for the grocery store and wait patiently while he tries to zip his jacket. According to Erikson, the parent who is over- or under-controlling in toileting is likely to be so in other aspects of the toddler’s life. The outcome is a child who feels forced and ashamed and doubts his ability to control his impulses and act competently on his own. In sum, basic trust and autonomy grow out of warm, sensitive parenting and reasonable expectations for impulse control starting in the second year.

Question 7.
State the Physical Hazards of infancy.
Answer:
Some of the physical hazards of infancy are of only temporary significance, while others can affect the individual’s entire life pattern. The most serious physical hazards are those relating to an unfavorable prenatal environment, a difficult and complicated birth, a multiple birth, postmaturity and prematurity and conditions leading to infant mortality.

Unfavorable Prenatal Environment:
As a result of unfavorable conditions in the prenatal environment, the infant may have difficulty adjusting to postnatal life. Excessive smoking on the part of the mother, for example, can affect the development of the fetus. Prolonged and intense maternal stress is another important factor, causing the infant to be tense and nervous.

Difficult and Complicated Birth:
A difficult or complicated birth frequently results in temporary or permanent brain damage. If the birth requires the use of instruments, as in the case where the fetus is so large that it has to be aided in its passage down the birth canal or if the fetus lies in a foot first or a transverse position, the chances of brain damage from the use of instruments to aid delivery are always present. A cesarean section or a precipitate birth, on the other hand, is likely to result in anoxia, a temporary loss of oxygen to the brain. If anoxia is severe, the brain damage will be far greater than if anoxia lasts for only a few seconds.

The more complicated the birth and the more damage there is to the brain tissue, the greater the effect on the infant’s postnatal life and adjustments. Severe and persistent brain damage will have adverse effects on all adjustments during infancy and often into childhood or even throughout life. The effects of brain damage are most frequently shown in uncoordinated behavior, hyperactivity, learning difficulties, and emotional problems. Multiple Birth Children of multiple births are usually smaller and weaker than singletons as a result of crowding during the prenatal period, which inhibits fetal movements. These babies tend to be born prematurely, which adds to their adjustment problems.

Postmaturity:
It is hazardous only when the fetus becomes so large that the birth requires the use of instruments or surgery, in which case the hazards are due to the conditions associated with birth rather than to postmaturity per se. One study of babies born more than three weeks after term reported that they experienced neonatal adjustment problems and were also socially maladjusted and required special schooling by the age of seven.

Prematurity:
Prematurity causes -more neonatal deaths than any other condition. Prematurely born infants are also especially susceptible to brain damage at birth because the skull is not yet developed enough to protect the brain from pressures experienced during birth. Anoxia is another common problem since the premature baby’s respiratory mechanism is not fully developed. The problems of adjustment every newborn infant must face are exaggerated in the premature.For example, they require nearly three times as much oxygen as full-term infants because their breathing is characterized by jerks and gasps.

They often have difficulty in expanding their lungs and muscular weakness makes breathing difficult. Because sucking and swallowing reflexes are underdeveloped, the premature infant will require special feeding with a medicine dropper or tube. The premature’s body temperature is not yet properly, controlled and special equipment is needed to duplicate as nearly as possible the constant temperature of intrauterine life.Infant Mortality UnQably the most serious of the physical hazards of infancy is infant mortality. The most critical times for death during the period of infancy are the day of birth (when two-thirds of all neonatal deaths occur and the second and third days after birth. Neonatal deaths have been reported to be most common during the months of June and July but, to date, no satisfactory explanation for this has been given.

The causes of infant mortality are numerous and varied.Some neonatal deaths are due to conditions that detrimentally affected the prenatal environment and thus impaired normal development. Some are the result of difficult and complicated births, such as those requiring the use of instruments or cesarean section. Some are the result of brain damage, anoxia, or excessive medication of the mother during labor. And some-but fewer than in the past are due to unfavorable conditions in the postnatal environment; a radical temperature change may cause pneumonia, for example, or a substitute for the mother’s milk may cause diarrhea or other digestive disturbances.

Question 8.
State Psychological Hazards of infancy.
Answer:
Even though psychological hazards tend to have less effect on the infant’s adjustment to postnatal life than physical hazards, they are nonetheless important because of their long-term effects. Psychological scars acquired during infancy can cause the individual lifelong adjustment problems. Relatively few of the potential psychological hazards of infancy have received more attention.

Traditional Beliefs about Birth Difficult births, for example, are believed to result in “difficult children” – those who are hard to handle and whose behavior tends to deviate from that of children born with a minimum of difficulty. For centuries it has been believed that children of multiple births have to be different and inferior to singletons and that premature are doomed to be physical and mental weaklings.

Time of birth on the future development of the child, while there is little scientific evidence to substantiate the belief that there is a “best time” to be born, there is evidence that, because the mother’s health plays an extremely important role during the prenatal period, any unfavorable condition during her pregnancy may and often does prove to be hazardous to her unborn child.

A baby who is born within a year after the birth of a sibling is subject to a less favorable prenatal environment than would have been the case had the interval between births been longer. The mother has not had time to recover fully from the previous birth, and such an infant tends to be lethargic at birth which affects postnatal adjustments. Throughout the early years of life, babies born soon after the birth of an older sibling are likely to receive less of their much-needed attention and stimulation because of the other demands on the mother’s time.

Helplessness To some parents the helplessness of the newborn infant is appealing while, to most, it is frightening, So long as the infants are in the hospital and under the care of doctors and nurses, parents are not too concerned about their helplessness. However, when they take them home from the hospital and assume responsibility for their care, infantile helplessness becomes a serious psychological hazard. The reason for this is that parents wonder if they are capable of assuming care of their newborn babies and this, in turn, makes them nervous and anxious.

Anxiety and insecurity are quickly transmitted to the infants through the way mothers handle them and this affects their postnatal adjustments. The helplessness of the newborn is more of a psychological hazard in the case of firstborns than of later-born children. By the time parents have had several children; they accept the helplessness of the newborn in a more relaxed way and are not so likely to be disturbed by it as they are for the firstborn infant.

The individuality of the Infant To most adults, being different is interpreted as being inferior. When parents steep themselves in child-care literature before the arrival of their first child, or when they set up norms of behavior based on what their earlier-born children did at different ages, they tend to judge a newborn infant in. these terms.

Parental concern is then expressed in their treatment of the infant. This, in turn, affects the infant’s adjustments to postnatal life and tends to increase the severity of the problems that concerned the parents. Under such conditions, the infant’s individuality becomes a psychological hazard which, unless parents accept individuality as normal, will play havoc with the adjustments made not only during infancy but also as childhood progresses.

Developmental Lag Some infants lag behind are those born prematurely or those who were injured at birth. Instead of regaining lost birth weight by the end of the first week or sooner, they may continue to lose weight or rest on a plateau with no improvement at all. Even worse, they may show such a pronounced lag that instead of being allowed to go home with their parents three to four days after birth, as is usual, they are kept in the hospital and may even have to have special nursing care.

Even a healthy, full-term infant may show developmental lag should there be some minor and temporary illness or should the mother’s milk be inadequate and the formula substituted is not suited to the infant’s needs. Plateau in Development Even though a plateau in development is normal immediately after birth, many first-time parents are unaware of this. As a result, they are concerned when their baby seems to be making no progress.

However, it often leaves some psychological obstacles, three of which are common and serious. First, it makes parents believe their infant is delicate and, as a result, should have extra care and attention. This encourages over protectiveness which, once developed, often persists as a habit. Second, it weakens parents’ confidence in their ability to assume full care of the infant after leaving the hospital . If by then the infant has not regained lost birth weight, this lack of confidence is greatly increased. And third, parents feel that they must handle the infant as little as possible and with great care to prevent further loss of weight or failure to gain weight. As a result, they deprive the infant of one of the essentials of development, stimulation of the different areas of the body.

Lack of Stimulation There is increasing scientific evidence that newborn infants need the stimulation of different areas of their bodies and of different sense organs if they are to develop as they should. This, of course, is not a “new-fangled idea” because, in the days when babies were born at home, they were picked up, rocked, talked to and sung to as part of their routine care.

Because it is customary today for babies to be born in hospitals, they are often deprived of the stimulation received by babies born at home or even by those whose mothers have them in their hospital rooms under the rooming-in plan. And, until very recently, premature infants were kept in isolettes or incubators where they received only the minimum of stimulation.

New-Parent Blues States of depression often called “new-parent blues,” are almost universal among new parents. These depressive states tend to be more pronounced in mothers than in fathers and in parents of first babies than in those who have already had one or more children. In new mothers, depressive states are partly physical and partly psychological. The glandular changes accompanying pregnancy and childbirth, fatigue from labor and childbirth and the generally weakened condition that persists even after normal childbirth all contribute to maternal states of depression.

For most fathers, new-parent blues are more psychological than physiological. They are often concerned about the extra expenses they must meet, especially if the mother must give up her job. Many men also are concerned about how the pattern of their lives will change as a result of parenthood and what effect this will have on their marital relationship. New-parent blues can and often do play havoc with the infant’s adjustments to postnatal life. The new baby senses the tensions of the parents, especially of the mother, and this makes it nervous and prone to crying. Many infants cry more after they get home than they did in the hospital.

Question 9.
Write the characteristics of early childhood.
Answer:
Just as certain characteristics of toddlerhood make it a distinctive period in the life span, so certain characteristics of early childhood set it apart from other periods. These characteristics are reflected in the names that parents, educators, and psychologists commonly apply to this period.

Names Used by Parents:
Early childhood is considered as a problem age or a troublesome age. While toddlerhood presents problems for parents, most of these centers around the baby’s physical care. With the dawn of childhood, behavior problems become more frequent and more troublesome than the physical-care problems of toddlerhood. As to why behavior problems dominate the early childhood years is that young children are developing distinctive personalities and are demanding independence which, in most cases, they are incapable of handling successfully.

In addition young children are often obstinate, stubborn, disobedient, negativistic, and antagonistic. They have frequent temper tantrums, they are often bothered by bad dreams at night and irrational fears during the day, and they suffer from jealousy. Due to these problems, early childhood seems less appealing age than toddlerhood to many parents. The dependency of the baby, so endearing to parents as well as to older siblings, is now replaced by resistance on the child’s part to their help and a tendency to reject demonstrations of their affection.

Furthermore, few young children are as cute as babies, which also make them less appealing. Early childhood is referred to the toy age because young children spend much of their waking time playing with toys. Studies of children’s play have revealed that toy play reaches its peak during the early childhood years and then begins to decrease when children reach school age. This, of course, does not mean that interest in playing with toys ends abruptly when the child enters school. Instead, with entrance into first grade, children are encouraged to engage in games and modified forms of sports, none of which require the use of toys. When alone, however, children continue to play with their toys well into the third or even fourth standard.

Names Used by Educators:
The early childhood years is referred as preschool age to distinguish it from the time when children are considered old enough, both physically and mentally, to cope with the work they will be expected to do when they begin their formal schooling Even when children go to nursery school or kindergarten, they are labeled preschoolers rather than school children. In the home, daycare center, nursery school, or kindergarten, the pressures and expectations young children are subjected to are very different from those they will experience when they begin their formal education in the first standard. The early childhood years, either in the home or in a, preschool, are a time of preparation.

Names Used by Psychologists:
A number of different names are used to describe the outstanding characteristics of the psychological development of children during the early years of childhood. One of the most commonly applied names is the pregang age, the time when children are learning the foundations of social behavior as a preparation for the more highly organized social life they will be required to adjust to when they enter first standard. Since the major development that occurs during early childhood centers around gaining control over the environment, many psychologists refer to early childhood as the exploratory age, a label that implies that children want to know what their environment is, how it works, how it feels and how they can be a part of it.

This includes people as well as inanimate objects. One common way of exploring in early childhood is by asking Qs: thus this period is often referred to as the Qing age. Imitation of the speech and actions of others are more pronounced during early childhood. For this reason, it is also known as the imitative age. However, in spite of this tendency, most children show more creativity in their play during early childhood than at any other time in their lives. For that reason, psychologists also regard it as the creative age.

Question 10.
State the developmental tasks of early childhood.
Answer:
Although the foundations of some of the developmental tasks young children are expected to master before they enter school are laid in toddlerhood, much remains to be learned in the relatively short four-year span of early childhood. When toddlerhood ends, all normal babies have learned to walk, though with varying degrees of proficiency; have learned to take solid foods and have achieved a reasonable degree of physiological stability.

The major task of learning to control the elimination of body wastes has been almost completed and will be fully mastered within another year or two. While most babies have built up a useful vocabulary, have reasonably correct pronunciation of the words they use, can comprehend the meaning of simple statements and commands, and can put together several words into meaningful Sentences, their ability to communicate with others and to comprehend what others say to them is still on a low level.

Much remains to be mastered before they enter school. Similarly, they have some simple concepts of social and physical realities, but far too few to meet their needs as their social horizons broaden and as their physical environment expands. Few babies know more than the most elementary facts about sex differences and even fewer understand the meaning of sexual modesty. It is questionable whether any babies, as they enter early childhood, actually know what is sex-appropriate in appearance and they have only the most rudimentary understanding of sex-appropriate behavior.

This is equally true of concepts of right and wrong. What knowledge they have is limited to home situations and must be broadened to include concepts of right and wrong in their relationships with people outside the home, especially in the neighborhood, in school, and on the playground. One of the most important and, for many young children, one of the most difficult of developmental tasks of early childhood, is learning to relate emotionally to parents, siblings, and other people.

The emotional relationships that existed during toddlerhood must be replaced by more mature ones. The reason for this is that relationships to others in . toddlerhood are based on babyish dependence on others to meet their emotional needs, especially their need for affection. Young children, however, must learn to give as well as to receive affection. In short, they must learn to be outer-bound instead of self-bound.

Question 11.
What are the influences on physical growth and health during childhood?
Answer:
While discussing growth and health in early childhood, heredity remains important, environmental factors continue to play crucial roles. Emotional well-being, good nutrition, relative freedom from disease and physical safety are essential.

Heredity and Hormones:
The impact of heredity on physical growth is evident throughout childhood. Children’s physical size and rate of growth are related to those of their parents. Genes influence growth by controlling the body’s production of hormones. The pituitary gland, located at the base of the brain, plays a critical role by releasing two hormones that induce growth. The first is growth hormone (GH), which from birth on is necessary for development of all body tissues except the central nervous system and genitals. Children who lack GH reach an average mature height of only 4 feet, 4 inches. When treated with injections of GH starting at an early age, these GH-deficient children show catch-up growth and then grow at a normal rate, reaching a height much greater than they would have without treatment.

The second pituitary hormone affecting children’s growth, thyroid-stimulating hormone (TSH), stimulates the thyroid gland (located in the neck) to release thyroxine, which is necessary for normal development of the nerve cells of the brain and for GH to have its full impact on body size. Infants born with a deficiency of thyroxine must receive it at once or they will be mentally retarded. At later ages, children with too little thyroxine grow at a below-average rate. By then, the central nervous system is no longer affected because the most rapid period of brain development is complete. With prompt treatment, such children catch up in body growth and eventually reach normal size.

Emotional Well-Being:
In childhood as in infancy, emotional well-being can have a profound effect on growth and health. Preschoolers with very stressful home lives (due to divorce, financial difficulties, or a change in their parents’ employment status) suffer more respiratory and intestinal illnesses and more unintentional injuries than others.
Extreme emotional deprivation can interfere with the production of GH and lead to psychosocial dwarfism, a growth disorder that appears between 2 and 15 years of age.

Typical characteristics include very short stature, decreased GH secretion, immature skeletal age and serious adjustment problems, which help distinguish psychosocial dwarfism from normal shortness. When such children are removed from their emotionally inadequate environments, their GH levels quickly return to normal and they grow rapidly. But if treatment is delayed, the dwarfism can be permanent.

Nutrition :
With the transition to early childhood, many children become unpredictable and choosy eaters. This decline in appetite is normal. It occurs because growth has slowed. Furthermore, preschoolers’ wariness of new foods may be adaptive. By sticking to “familiar foods, they are less likely to swallow dangerous substances when adults are not around to protect them. Parents need not worry about variations in amount eaten from meal to meal. Preschoolers compensate for a meal in which they ate little with a later one in which they eat more.

Even though they eat less, preschoolers need a high-quality diet. They require the same foods adults do-only smaller amounts. Fats, oils and salt should be kept to a minimum because of their link to high blood pressure and heart disease in adulthood. Foods high in sugar should also be avoided. In addition to causing tooth decay, they lessen young children’s appetite for healthy foods and increase their risk of being overweight and obese.

The social environment powerfully influences young children’s food preferences. Children tend to imitate the food choices of people they admire-adults as well as peers. A pleasant mealtime climate also encourages healthy eating. Repeated exposure to a new food (without any direct pressure to eat it) increases children’s acceptance. Sometimes parents bribe their children, saying, “Finish your vegetables and you can have an extra cookie.” This practice causes children to like the healthy food less and treat more. Too much parental control over children’s eating limits their opportunities to develop self-control.

Infectious Disease:
In well-nourished children, ordinary childhood illnesses have no effect on physical growth. But when children are undernourished, disease interacts with malnutrition in a vicious spiral, and the consequences for physical growth can be severe. Infectious Disease and Malnutrition. Illnesses such as measles and chicken pox, which typically do not appear until after age 3 in industrialized nations, occur much earlier. Poor diet depresses the body’s immune system, making children far more susceptible to disease. Of the 10 million annual worldwide deaths in children under age 5, 99 percent are in developing countries and 70 percent are due to infectious diseases. Disease, in turn, is a major cause of malnutrition and through it, hinders physical growth. Illness reduces appetite and limits the body’s ability to absorb foods. These outcomes are especially severe in children with intestinal infections.

In developing countries, diarrhea is widespread and increases in early childhood because of unsafe water and contaminated foods, leading to growth stunting and several million childhood deaths each year. Most growth retardation and deaths due to diarrhea can be prevented with nearly cost-free oral rehydration therapy (ORT), in which sick children are given glucose, salt, and water. Immunization  In industrialized nations, childhood diseases have declined dramatically during the past half-century, largely due to the widespread immunization of infants and young children. All children were guaranteed free immunizations, a program that has led to a steady improvement in early childhood immunization rates. The inability to pay for vaccines, however, is only one cause of inadequate immunization.

Misconceptions also contribute for example, the notion that vaccines do not work or that they weaken the immune system. Furthermore, some parents have been influenced by media reports suggesting that the measles-mumps-rubella vaccine has contributed to a rise in a number of children diagnosed with autism. Yet large-scale studies show no association between immunization and autism. Public education programs directed at increasing parental knowledge about the importance and safety of timely immunizations are badly needed. Diseases that spread most rapidly are diarrhea and respiratory infections the illnesses most frequently suffered by young children. The risk that a respiratory infection will result in otitis media, or middle ear infection, is almost double that of children remaining at home.

Childhood Injuries:
Unintentional injuries – auto collisions, pedestrian accidents, drownings, poisonings, firearm wounds, bums, falls, and swallowing of foreign objects-are the leading cause of childhood mortality in industrialized countries. Among injured children and youths who survive, thousands suffer pain, brain damage, and permanent physical disabilities. Auto and traffic accidents, drownings, and bums are the most common injuries during early childhood. Motor vehicle collisions are by far the most frequent source of injury at all ages, ranking as the leading cause of death among children more than 1-year-old.

Question 12.
Notes on Factors Related to Childhood Injuries.
Answer:
We are used to thinking of childhood injuries as “accidental.” But a close look reveals that meaningful causes underlie them and we can, indeed, do something about them. Individual differences exist in the safety of children’s behaviors. Because of their higher activity level and a greater willingness to take risks during play, boys are more likely to be injured than girls. Temperamental characteristics-irritability, inattentiveness, and negative mood are also related to childhood injuries. Children with these traits present special childrearing challenges. They are likely to protest when placed in auto seat restraints, to refuse to take a companion hand when crossing the street, and to disobey even after repeated adult instruction and discipline.

Poverty, low parental education, and more children in the home are also strongly associated with injury. Parents who must cope with many daily stresses often have little time and energy to monitor the safety of their youngsters. And their homes and neighborhoods pose further risks. Noise, crowding, and confusion characterize run-down, inner-city neighborhoods with few safe places to play. Poverty, rapid population growth, overcrowding in cities and heavy road traffic combined with weak safety measures are major causes. Safety devices, such as car safety seats and bicycle helmets, are neither readily available nor affordable in most developing countries. This indicates that besides reducing poverty and teenage pregnancy and upgrading the status of child care, additional steps must be taken to ensure children’s safety.

Preventing Childhood Injuries. Childhood injuries have many causes, so a variety of approaches are needed to control them. Laws prevent many injuries by requiring car safety seats, child-resistant caps on medicine bottles, flameproof clothing, and fenced-in backyard swimming pools.

Question 1:
What do mean by Life span development? Explain the same on today’s concept.
Answer:
Life Span Development or Developmental psychology is the branch of psychology that studies intraindividual changes and interindividual changes within these intraindividual changes. Its task, as La Bouvier has pointed out, is “not only description but also explication of age-related changes in behavior in terms of antecedent-consequent relationships”.

Developmental psychologists study developmental change covering the life span horn conception to death. By so doing, they attempt to give a complete picture of growth and decline. Others cover only a segment of the life span-childhood, adulthood, or old age. In this book, an attempt will be made to cover all segments and show the important developmental changes at different periods during the entire life span.

Siegel during the early years, as has explained, “Life span psychology was preoccupied with ages and stages. Investigators sought to learn the typical age at which various stages of development occurred”. The areas inr which research was mainly concentrated were those considered significant for human evolutional adaptation. For the most part, research studies were concentrated on preschool and school-age children and on adolescents. Only later did research extend downward, first to birth and then to conception and later upward, to adulthood, old age and finally to middle age.

The two major reasons for the uneven emphasis of developmental psychology,

The study of a particular period in the developmental pattern has been greatly influenced by the desire to solve some practical problem or problems associated with that period. Research in the area of middle age, for example, is an outgrowth of the realization that good adjustments in the latter years of life depend on how well one has adjusted to the physical; and psychological changes, that normally occur in the middle years.

Since the focus of interest in life span psychology has changed over the years, there are gaps in our knowledge of the different developmental phenomena characteristic of the different periods. These gaps are also due in part to difficulties in studying the different patterns of behavior characteristic of a given period, especially difficulties in getting representative samplings of subjects of a given age and in finding a suitable method for the study of behavior patterns.

The reason for the uneven emphasis is that it is – harder to study people at some stages of life than at others. Getting middle-aged and elderly subjects, for example, is far more difficult than getting preschool or school-age children or even adolescents.

Life Span psychologists have six major objectives:

  • to find out what are the common and characteristic age changes in appearance, in behavior, in interests, and in goals from one developmental period to another;
  • to find out when these changes occur;
  • to find out what causes them;
  • to find out how they influence behavior;
  • to find out whether they can or cannot be predicted and
  • to find out whether they are individual or universal.

Question 2:
Discuss the early approaches towards Life span development.
Answer:
Early forerunners of the scientific study of development were baby biographies, journals kept to record the early development of a child. One early journal, published in 1787 in Germany, contained Dietrich Tiedemann’s (1897/1787) observations of his son’s sensory, motor, language and cognitive behavior during the first 21/2 years. Typical of the speculative nature of such observations was Tiedemann’s erroneous conclusion, after watching the infant suck more on a cloth tied around something sweet than on a nurse’s finger, that sucking appeared to be “not instinctive, but acquired”.

It was Charles Darwin, the originator of the theory of evolution, who first emphasized the developmental nature of infant behavior. In 1877 Darwin published notes on his son Doddy’s sensory, cognitive and emotional development, during his first twelve months. Darwin’s journal gave “baby biographies” scientific respectability; about thirty more were published during the next three decades.

By the end of the nineteenth century, several important trends in the western world were preparing the way for the scientific study of development. Scientists had unlocked the mystery of conception and were arguing about the relative importance of “nature” and “nurture” (inborn characteristics and experiential influences). The discovery of germs and immunization made it possible for many more children to survive infancy.

Laws protecting children from long workdays let them spend more time in school and parents and teachers became more concerned with identifying and meeting children’s developmental needs. The new science of psychology taught that people could understand themselves by learning what had influenced them as children. Still, this new discipline had far to go.

For example, adolescence was not considered a separate period of development until the early twentieth century, when G. Stanley Hall, a pioneer in child study, published a popular (though unscientific) book called Adolescence (1904/1916). Hall also was one of the first psychologists to become interested in aging. In 1922, at age 78, he published Senescence: The Last Half of Life. Six years later, Stanford University opened the first major scientific research unit devoted to aging. But not until a generation later did the study of aging blossom.

Since the late 1930s a number of important long-term studies discussed in the second half of this book, such as those of K. Warner Schaie, George Vaillant, Daniel Levinson and Ravenna Helson, have focused on intelligence and personality development in adulthood and old age.

Question 3:
Explain the meaning and development of changes.
Answer:
Development means a progressive series of changes that occur as a result of maturation and experience. As Van den Daele has pointed out, “development implies qualitative change”. This means that development does not consist merely of adding inches to one’s height or of improving one’s ability. Instead, it is a complex process of integrating many structures and functions.

There are two essentially antagonistic processes in development take place simultaneously throughout life – growth, or evolution and atrophy, or involution. Both begin at conception and end at death. In the early years, growth predominates, even though atrophic changes occur as early as embryonic life. In the latter part of life, atrophy predominates, though growth does not stop; hair continues to grow and cells continue to be replaced. With aging, some parts of the body and mind change more than others.

The human being is never static. From conception to death, change is constantly taking place in physical and psychological capacities. As Piaget has explained, structures are “far from being static and given from the start.” Instead, a maturing organism undergoes continued and progressive changes in response to experiential conditions and these result in a complex network of interaction.

As development is continuous, as Bower has pointed out, in the sense that it is a cyclic process with competencies developing and then disappearing, only to appear at a later age, it is not continuous in the sense that it increases constantly but rather in a series of waves with whole segments of development reoccurring repetitively. Bower has explained, newborns walk if held and then this ability disappears only to reappear at eight or ten months of age.

He explains that the “various explanations of repetitive processes in development thus seem to differ depending on the specific repetition to be explained. What all the explanations have in common, however, is that they preserve the assumption that psychological growth, in spite of its apparent reversals, is a continuous and additive process”. When regression to an earlier stage occurs, there is usually a cause for it, as in the regression to the awkwardness that occurs with the rapid growth at puberty.. ‘

The pattern of change resembles a bell-shaped curve, rising abruptly at the start and then flattening out during the middle years, only to decline slowly or abruptly in old age. It is important to recognize that at no time can this pattern be represented by a straight line, though plateau periods of short or long duration may occur in the development of different capacities.

Question 4:
What is the Goal of Life span Changes?
Answer:
It is to enable people to adapt to the environment in which they live. To achieve this goal, self-realization, or, as it is sometimes called, ‘Self-actualization,” is essential. However, this goal is never static. It may be considered an urge-the urge to do what one is fitted to do, the urge to become the person, both physically and psychologically, that one wants to be.

The way people express this urge depends on the individual’s innate abilities and training, not only during the early, formative years of childhood but also as he or she grows older and comes under greater pressures to conform to social expectations. Since self-realization plays an important role in mental health, people who ‘make good personal and social adjustments must have opportunities to express their interests and desires in ways that give them satisfaction but, at the same time, conform to accepted standards. Lack of these opportunities will result in frustrations and generally negative attitudes toward people and toward life in general.

Question 5:
Discuss Researches on Life span Change.
Answer:
Research on developmental changes during childhood and adolescence has been far more extensive than studies of changes that occur during the later years. Among the reasons for this uneven emphasis is the fact that the many prevailing traditional beliefs about children and adolescents have acted as a spur to researchers, who have set up studies designed to prove or disprove these beliefs.

Traditional beliefs concerning the post-adolescent years are less numerous and have had less impact on the direction of research. Further, developmental changes occurring at middle age were regarded as purely physiological and, therefore, outside the scope of psychological research. Changes occurring in old age affected a relatively small percentage of the population and were thus considered less important than changes that occur during the early years. It is now recognized that changes occurring at any developmental stage are worthy of study.

The most important incentive to research about developmental changes has been the nature-nurture controversy which has raged for decades. How important a role maturation based on genetic factors plays in bringing about developmental changes as compared with environmental pressures and experiences has been the focal point of interest and many research studies have been devoted to trying to find a satisfactory solution to this controversy.

The research on developmental changes at all stages has been the emergence of a large number of new theories about the causes and effects of such changes. These theories are not always backed up by adequate evidence and a great deal of research is motivated by the desire to substantiate or refute material that has widespread acceptance in the field.

Any new theory can lead to controversy and experimentation, but of all theories, none have provided a more powerful incentive to research than Piaget’s developmental theories, especially his theories about cognitive development. Other views that have inspired numerous studies are Kohlberg’s stages of moral development and Gesell’s stages of equilibrium and disequilibrium.

Question 6:
Attitudes toward Life span Changes
Answer:
Changes of a physical or psychological nature are constantly taking place; many people are only vaguely aware of them unless they occur abruptly or markedly affect the pattern of their lives. The changes of old age, for example, usually occur at a much slower pace than those of childhood or adolescence. However, they still require readjustments on the part of all individuals. But, when individuals can make these adjustments relatively slowly, they themselves or others may not be conscious of them.

Thus when changes are rapid, on the other hand, the individual is only too well aware of them, as are others. During the puberty growth spurt at the end of childhood and the beginning of adolescence, such comments as “My, how you have grown since last saw you!’’ are evidence of how others notice these changes. Similarly, in senescence, when the downward movement begins to accelerate, the elderly are aware of the fact that their health is “failing” and that their minds are “slipping.” Constant readjustment to these changes is necessary in the scheduled pattern of their lives.

They must slow down as the incapacities and infirmities of old age catch up with them and they must frequently forgo some of the activities that formerly played important roles in their lives. As there is, a tendency for most people to regard the past as better than the present. And even though most children look forward to the day when they will be “teenagers,” when that time comes they often long for the carefree days of their childhood.

Similarly, many men who look forward to retirement wish, when the mandatory age for retirement arrives, that they could go back to earlier years when their usefulness and prestige were recognized by the social group. As and when people become aware of the changes taking place in them, they develop definite attitudes toward these changes. Whether these attitudes will be favorable or unfavorable depends on a number of factors, the most important of which are described below.

Question 7:
Write the aspects that influence attitudes toward Life span changes.
Answer:

Appearance:
Developments that improve one’s appearance are welcome and lead to favorable attitudes while those that detract from one’s appearance are resisted and every possible attempt is made to camouflage them.

Behavior:
As and when behavior changes are disconcerting, as during puberty and senescence, they affect attitudes toward the changes unfavorably. The reverse is true when changes are favorable, as occurs, for example, when the helplessness of babyhood gradually gives way to the independence of childhood.

Cultural Stereotypes:
From mass media, people learn cultural stereotypes associated with different ages and they use these stereotypes to judge people of those ages.

Cultural Values:
Each culture has certain values associated with different ages. Because maximum productivity is associated with young through early middle-age adulthood, attitudes toward this age group are more favorable than attitudes toward other ages.

Role Changes:
Attitudes toward people of different ages are greatly influenced by the roles they play. When people change their roles to less favorable ones, as in the case of retirement or widowhood, social attitudes toward them are less sympathetic.

Personal Experiences:
Personal experiences have a profound effect on an individual’s attitude toward developmental changes. Since the authority and prestige of middle-aged executives decreases as they approach retirement their attitudes toward aging are, for example, unfavorably affected. These attitudes are intensified by unfavorable social attitudes.

Question 8:
What are the Obstacles in Studying Life-Span Development?
Answer:
All studies of the Life span are beset by obstacles in varying degrees. The five most common and most serious of these are discussed below.

Representative Samples of Subjects:

The first obstacle scientists encounter in studying development during the life span is securing representative samples of subjects at different age levels, although it is relatively easy to get representative samples of subjects from among schoolchildren and college students. In the case of newborn infants, however, researchers often meet with strong parental objections.

Getting older adolescents and young adults who are not attending school to volunteer as subjects is also difficult because they may not be available for study at any one particular place. This difficulty increases with advancing age, which is why so many of the studies relating to the latter years of life have been made on men and women living in institutions, people who unQably are not representative of the general population.

Recruiting young adults, middle-aged adults, or the elderly as voluntary participants in experiments has likewise been a difficult task, even when they are paid for their time. Many persons shy away from any testing programme, partly because of a lack of personal interest but mainly because they are afraid they will not do well and, as a result, create an unfavorable impression. Relying on those who are willing to participate may be creating a bias just as using institutional cases does.

Establishing Rapport with Subjects:

The second obstacle scientists encounter in studying development during the lifespan is establishing rapport with subjects at different age levels. There is no guarantee that scientists will be able to elicit the information they are seeking from any group unless they are able to establish rapport with their subjects. Therefore, there is no guarantee that the data they obtain is as accurate or as comprehensive as it might have been had a better relationship existed between subjects and experimenters.

The reason for this is that obtaining information from subjects of any age is extremely difficult because most people resent having a stranger pry into their personal affairs. Even schoolchildren and college students, who often take tests or fill out Qnaires as part of their classroom work* show their resentment by being uncooperative or even by falsifying the information they give. This is even truer of adults of all ages. Their resentment at participating in a scientific study may be partially overcome if they are paid to do so, but they tend to regard the experimenter as an invasion of privacy.

As a result, it is questionable whether data obtained from many studies is a true picture of the involved individuals’ attitudes, feelings and values. Only when good rapport can be established with the subjects and when there is evidence of cooperation on their part can great confidence be placed in the results of these studies.

Methodology:

The third obstacle scientists encounter in studying development during the life span is securing a satisfactory method. This is because no one method can be used satisfactorily for studying people at all ages or for investigating all areas of development. Some of the methods that must be resorted to, for lack of better ones, are of dubious scientific value.

Because of the wide age range of subjects and the variety of different areas of development that must be studied to give a composite picture, assorted methods have had to be used. Some have been borrowed from medicine, from the physical sciences and from related social sciences, especially anthropology and sociology. Some have made use of laboratory settings and others of the naturalistic settings of the home, school, community, or work environment. Some are regarded as reliable, while others, especially the retrospective and introspective techniques, are of questionable value.

Regardless of the method used, most of the studies have been cross-sectional comparisons of the same abilities at different stages of development. As such, they do not give evidence about developmental trends or about intraindividual variability. Nor is it possible, when using cross-sectional comparisons, to assess the relative behaviour constellations of individuals at an early age and similar behavior in adult life. One of the most serious problems connected with the cross-sectional approach is that it is almost impossible to get comparable groups of subjects for study at different age levels.

This can bias the result of studies, especially studies of old age. When mental abilities are studied using the cross-sectional approach, mental decline is reported to be far greater than when the same mental abilities are studied using the longitudinal approach. This, in turn, has given scientific backing to the popular belief that mental decline in old age is not only great but also universal.

Another serious problem associated with the cross-sectional approach is that it does not take into consideration cultural changes which always play a major role in the patterns of physical and mental development. This results in a tendency to interpret any change that may appear as an age change. Cultural changes affect values, among other things. A comparison of adolescents of today with members of the older generation showed that the latter tend to disapprove more strongly of extravagance than adolescents do.

This might be interpreted to mean that members of the older generation have become rigid with age. In reality, the difference is one of cultural values. When members of the older generation were growing up, high value was placed on prudent spending of money and on having a nest egg for the proverbial rainy day. Today, adolescents are growing up in a culture dominated by the philosophy of “earn more and spend more”. Because of the rapid change in cultural values taking place at the present time, children often consider their parents’ values old-fashioned.

Accuracy of Data Obtained:

The fourth obstacle scientists encounter in studying development during the life span is ensuring that the data obtained from the studies will be accurate. Inaccuracies may result when a biased sampling of subjects gives a false picture of the normal developmental pattern at a particular age. This can happen, for example, when institutionalized elderly people are used for the study and the subjects try to present as favorable a picture of them as they can and either consciously or unconsciously, distort their introspective or retrospective reports.

It can also occur when the only method available for studying a certain area of development is less than satisfactory. In the measurement of intelligence, it is still questionable if the results are accurate for the first two years of life. There is even controversy about the accuracy of intelligence tests for older age levels. Observational techniques for the study of behavior during the preschool years are Qed for accuracy because of the tendency of observers to draw inferences from their study of children’s behavior and speech.

Ethical Aspects of Research:

The fifth obstacle scientists encounter in studying development during the lifespan involves the ethical aspects of research. Today there is a growing trend to take this into account and it has been a stumbling block to certain kinds of studies, which, in the past, were made without consideration of their fairness to the subjects studied. With the trend nowadays toward considering the rights of subjects, emphasis in being placed on asking their consent to participate in experiments, or, for the very young, the consent of their parents or guardians.

Such consideration also applies to high school and college students; they no longer are expected to take time from their studies to participate in experiments unless they are paid to, do so. Thus there is a tendency to bias the sampling because only those who need the money or those who feel that the money is worth their while are willing to accommodate the researcher.

Question 9:
Write characteristics of the pre-natal period.
Answer:
In spite of the fact that the first developmental period in the life span is next to the shortest of all-the shortest is the period of the newborn or infancy- it is in many respects one of the most, if not the most, important periods of all. This period, which begins at conception and ends at birth, is approximately 270 to 280 days in length, or nine calendar months.

Although it is relatively short, the prenatal period has six important characteristics, each of which has a lasting effect on development during the life span. They are as follows:

The hereditary endowment, which serves as the foundation for later development, is fixed, once and for all, at this time. While favorable or unfavorable conditions, both before and after birth may and probably will affect too. some extent the physical and psychological traits that make up this hereditary endowment, the changes will be quantitative, not qualitative.

Favorable conditions in the mother’s body can foster the development of hereditary potentials while unfavorable conditions can stunt their development, even to the point of distorting the pattern of future development. At few, if any other times in the life span are hereditary potentials so influenced by environmental conditions as they are during the prenatal period.

The sex of the newly created individual is fixed at the time of conception and conditions within the mother’s body will not affect it, as is true of the hereditary endowment. Except when surgery is used in sex transformation operations, the sex of the individual, determined at the time of conception, will not change. Such operations are rare and only partially successful.

Proportionally greater growth and development take place during the prenatal period than at any other time throughout the individual’s entire life. During the nine months before birth, the individual grows from a microscopically small cell to an infant who measures approximately twenty inches in length and weighs, on average, 7 pounds. It has been estimated that weight during this time increases eleven million times. Development is likewise phenomenally rapid. From a cell that is round in shape, all the bodily features, both external and internal, of the human being develop at this time. At birth, the newly born infant can be recognized as human even though many of the external features are proportionally different from those of an older child, an adolescent, or an adult.

The prenatal period is a time of many hazards, both physical and psychological. While it cannot be claimed that it is the most hazardous period in the entire life span-many believe that infancy’s more hazardous-it certainly is a time when environmental or psychological hazards can have a marked effect on the pattern of later development or may even bring development to an end.

The prenatal period is the time when significant people form attitudes toward newly created individuals. These attitudes will have a marked influence on the way these individuals are treated, especially during their early, formative years. If the attitudes are heavily emotionally weighted, they can and often do play havoc with the mother’s homeostasis and, by so doing, upset the conditions in the mother’s body that are essential to the normal development of the newly created individual.

Question 10:
What is the importance of conception?
Answer:
At the time of conception, four important conditions are determined that influence the individual’s later development. What role each of these conditions plays in the individual’s development will explain why the time of conception is probably the most important period in the life span.

Hereditary Endowment:

The first important happening at the time of conception is the determination of the newly created individual’s hereditary endowment. The contributions to this endowment from both parents and from both maternal and “paternal ancestors. Because the hereditary endowment is determined once and for all at the time of conception, its importance is far greater than it Would be if it were subject to later change.

The determination of hereditary endowment affects later development in two ways. First, heredity places limits beyond which individuals cannot go. If prenatal and postnatal conditions are favorable and if people are strongly motivated, they can develop their inherited physical and mental traits to their maximum potential, but they can go no further. Montagu has stressed, “Where we control the environment, we to some extent control heredity. Heredity, it has been said, determines what we can do and environment what we do do”.

The second important thing about the hereditary endowment is that it is entirely a matter of chance: there is no known way to control the number of chromosomes from the maternal or paternal side that will be passed on to the child. Scheinfeld has pointed out that the birth of a given individual depends on the union of a particular ovum with a particular sperm.

Sex:
Determination of the individual’s sex happens during conception. It is known that the sperm cell-that is, the father-determines the sex of a child. At conception, the zygote receives 23 chromosomes from the sperm and 23 from the ovum. (Figure 1 and 2)They align themselves in pairs: 22 pairs are autosomes, or nonsex chromosomes; the twenty-third pair is sex chromosomes, which determine if the new human being will be male or female. In females, this pair is called XX; in males, it is called XY.

The X is a relatively long chromosome, whereas the Y is short and carries little genetic material. When gametes are formed in males, the X and Y chromosomes separate into different sperm cells. In females, all gametes carry an X chromosome. Therefore, the sex of the new organism is determined by whether an X-bearing or a Y-bearing sperm fertilizes the ovum.

Sex depends on the kind of spermatozoon that unites with the ovum. Once the male and female cells have united, nothing can be done to change the sex of the newly formed individual. Whether this individual is male or female will have a lifelong effect on the individual’s patterns of behavior and personality.
There are three reasons why the sex of an individual is important to lifelong development.

First, each year children come under increasing cultural pressures from parents, teachers, their peer group and society at large to develop attitudes and behavior patterns that are considered appropriate for members of their sex. Children who learn to behave in ways that are considered appropriate for their sex are assured of social acceptance. By contrast, children who fail to conform are subjected to criticism and social ostracism.

Second, learning experiences are determined by the individual’s sex. In the home, at school and in playgroups, children learn what is considered appropriate for members of their sex. A boy who learns to play girls’ games is labeled a “sissy” and girls who prefer boys games are known as “tomboys.”Third and perhaps most important of all, is the attitude of parents and other significant family members toward individuals because of their sex.

Studies of sex preferences for offspring have revealed that the traditional preference for a boy, especially for the firstborn, still persists. Strong preferences for a child of a given sex have marked influences on parents’ attitudes, which in turn affect their behavior toward the child and their relationships with the child. Number of Offspring:

The third important happening at the time of conception or shortly thereafter is the determination of the number of offspring there will be. While most humans are singletons, multiple births also occur. Meredith has reported that out of 80 births is twins, 1 out of every 9,000 is triplets and 1 out of every 570,000 is quadruplets. There are more frequent multiple births among blacks and fewer among Chinese, Japanese and other Mongoloid- race groups than there are among whites.

When a ripe ovum is fertilized by one spermatozoon, the result will be a singleton, unless the fertilized ovum (zygote) splits into two or more distinct parts during the early stages of cell cleavage. When this happens, the result will be identical (uniovular) twins, triplets, or other multiple births. If two or more ova are released simultaneously and are fertilized by different spermatozoa, the result will be nonidentical {also called biovular or fraternal) twins, triplets, or other multiple births.

Approximately one-third of all twins are identical. Because the chromosomes and genes of the two or more zygotes from which individuals of nonidentical multiple births develop are not the same, their mental and physical make-ups are different. By contrast, those of identical multiple births come from the same zygote and consequently, they have the same assortment of chromosomes and genes. Children of identical multiple births are always of the same sex, while those of nonidentical multiple births may be of the same or opposite sex. Effects on Development:

Most studies of the effects of multiple births on development have been limited to twins for the reason that triplets, quadruplets and other multiple births occur very infrequently and the mortality rates among them are much higher than among twins, thus making studios of them difficult if not impossible.

However, there is reason to assume that the effects of multiple birth on triplets, quadruplets, and other multiples is much the same as on twins though the former feel these effects to a greater extent. The reason that multiple births affect the pattern of development is not only that there are differences in heredity but that both the prenatal environment and the postnatal environment of singletons are different from those of children of multiple births. This contributes to different patterns of development, different patterns of behavior and differences in personality.

Question 11:
Write Some Common Developmental Characteristics of Twins.
Answer:
Developmental lag: In physical, mental, motor, and speech development, twins tend to lag behind singletons of the same age. Log in motor and speech development may be due to brain damage or to prematurity but it is more likely to be due to parental over-protectiveness.

Physical Development:
Twins tend to be smaller, age for age, than singletons. This is generally due to the fact that they are premature. They also suffer from brain damage and other physical defects more often than singletons.

Mental Development:
Mental similarities between identical twins are much greater than between nonidentical twins and this persists into old age. Identical twins also show strong similarities in terms of special abilities, such as musical and artistic aptitudes.

Social Development:
Twins tend to compete for adult attention, to imitate each other’s speech and behaviour and to depend on each other for companionship during the preschool years. As they grow older, sibling rivalry and competition develop. One twin usually takes on the role of leader, forcing the other into the role of follower. This affects their relationships with other family members and with outsiders.

Personality Development:
Many twins have difficulty in developing a sense of personal identity. This is especially true of identical twins and of nonidentical twins of the same sex. Others enjoy the close relationship of twinship and the attention they receive as a result of their similarity in appearance. This leads to self-satisfaction and self-confidence.

Behavior Problems:
Behavior problems have been reported to be more common among twins than among singletons of the same age. It is thought that this is a result of the way twins are treated, both at home and outside the home. Behavior problems have also been reported to be more common among nonidentical than among identical twins. It has been suggested that this is because rivalry is stronger between nonidentical than identical twins. Long-Term Effects of Twinship Those that have been made rarely go beyond the tenth year of the twins’ lives have indicated the following long-term effects. There is a tendency for the developmental lag in physical development to end before children reach puberty and often much earlier.

Generally, the firstborn twin continues to be larger, brighter, and better adjusted socially throughout the childhood years. The smaller the twins at birth, the longer the developmental lag tends to persist. The mutual dependency or “twinning relationship” so common among young twins and the one-sided dependency of the smaller on the larger twin generally give way to social relationships similar to those of singletons before the twins enter school. Those who attend daycare centers or preschools tend to abandon these patterns of dependency earlier than twins whose environment is limited to the home. F rate mal twins are more vulnerable to external pressures and to have less support from the twinship relationship than do identical twins not only when they are young but also as they grow older.

Question 12:
What are the hazards during the prenatal period?
Answer:
At no other time during the life span are there more serious hazards to the development-or hazards” of a more serious nature than during the relatively short period before birth. These may be physical or psychological. Physical hazards have received more scientific attention because they are more easily recognized.
However, psychological hazards are sometimes as serious as physical hazards since they affect the attitudes of significant people toward the developing child. Furthermore, they often intensify physical hazards.

Physical Hazards :
Each of the three major subdivisions of the prenatal period involves particular physical hazards. While these do not affect all individuals by any means, they do occur with some. frequency and can be serious enough to affect the development of the individual throughout life. Davis and
(a) Common Physical Hazards during the Prenatal Period :
Period of the Zygote

Starvation:
The zygote will die of starvation if it has too little yolk to keep it alive until it can lodge itself in the uterine wall or if it remains too long in the tube.

Lack of Uterine Preparation:
Implantation can not occur if, as a result of glandular imbalance, the uterine walls are not prepared in time to receive the zygote.

Implantation in the Wrong Place:
If the zygote becomes attached to a small fibroid tissue in the uterine wall or to the wall of the Fallopian tube, it can not get nourishment and will die. Period of the Embryo:

Miscarriages:
Falls, emotional shocks, malnutrition, glandular disturbances, vitamin deficiency, and serious diseases, such as pneumonia and diabetes, can cause the embryo to become dislodged from its place in the uterine wall, resulting in a miscarriage. Miscarriages that are due to unfavorable conditions in the prenatal environment are likely to occur between the tenth and eleventh weeks after conception.

Developmental Irregularities:
Maternal malnutrition vitamin and glandular deficiencies excessive use of drugs, alcohol, and tobacco, and diseases, such as diabetes and German measles, interfere with normal development, especially that of the embryonic brain. Period of the Fetus:

Miscarriages:
Miscarriages are always possible up to the fifth month of pregnancy; the most vulnerable time is when the woman’s menstrual period would normally occur.

Prematurity:
Fetuses who weigh less than 2 pounds 3 ounces have less chance of surviving than heavier fetuses and a greater chance of developing malformations.

Complications of Delivery:
Maternal stress affects uterine contractions and is likely to lead to complications during birth.

Developmental Irregularities:
Any of unfavorable environmental conditions present during the period of the embryo will also affect the development of fetal features and retard the whole pattern of fetal development.

Conditions Influencing Physical Hazards:
Certain conditions have been found to increase the likelihood that physical hazards will occur or accentuate them. The first of these conditions is the timing of their appearance. It has been recognized by doctors for many years that if the mother-to-be contracts rubella during the first trimester of pregnancy the chances of developmental irregularities in her unborn child, especially in the form of an eye or a malformation of the heart, will occur. Female hormones, such as estrogen and progestin, when taken in the early stages of pregnancy may disturb the normal cardiovascular development of the fetus and cause congenital heart diseases.

It is reported that the second and third lunar months, when the heart is developing rapidly, are the most serious times. This is not true if these hormones are taken after the fourth lunar month. The second condition that increases the likelihood of physical hazards is if the condition is intense or greater than is normal. Some conditions that are known to affect the developing child during the prenatal period are described below others are suspected of affecting development. Maternal malnutrition can play havoc with normal development, especially the development of the fetal brain. Excessive smoking and drinking are detrimental to normal development, especially during the periods of the embryo and fetus. This is true also of taking drugs. Maternal age has been reported to be a condition that intensifies the possibility of physical hazards during the prenatal period.

The reason for this is that as women approach menopause, they frequently have endocrine disorders which slow down the development of the embryo and fetus, causing such developmental irregularities as cretinism, Down’s syndrome, heart malformations and hydrocephalus all of which involve physical and mental defects. The incidence of Down’s syndrome increases as age advances in women. Older women also tend to have smaller babies and to have more complications at birth than do younger women. While paternal age may likewise cause developmental irregularities or stillbirths, this is likely to happen only when paternal age is over sixty years.

Certain kinds of work are more likely to disturb prenatal development than others. Chemicals and other hazards faced by women working in such places as hospitals, beauty parlors and factories may be responsible for the increasing number of birth defects and miscarriages during recent years. Multiple births are more hazardous than single births. Fetuses of multiple births are crowded during the prenatal period and this inhibits the normal fetal activity essential for development. Prematurity is also more likely in the case of multiple births, as is the possibility of developmental irregularities. Because multiple births are more common among blacks than among whites, this may account in part for the higher infant mortality rate and the greater incidence of developmental irregularities among blacks than among whites.
