Madhya Pradesh Board Class 12 Psychology — NCERT Solutions

Given/Context: The question asks about the psychological characterisation and definition of intelligence.

Answer:

Psychologists have defined and characterised intelligence in several ways:

1. General Definition: Intelligence refers to an individual's capacity to understand the world, think rationally, and use resources effectively when faced with challenges or demands of life.

2. Psychometric Approach: Early psychologists like Binet and later Spearman characterised intelligence as a measurable set of abilities. Spearman proposed a two-factor theory — a general factor ($g$) underlying all intellectual tasks, and specific factors ($s$) for particular tasks.

3. Multiple Abilities View: Thurstone identified Primary Mental Abilities (verbal comprehension, numerical ability, spatial ability, etc.), suggesting intelligence is not a single entity but a cluster of distinct abilities.

4. Information-Processing Approach: Sternberg defined intelligence as the mental processes used to plan and solve problems. Das described it through the PASS model (Planning, Attention-Arousal, Simultaneous, Successive processing).

5. Multiple Intelligences (Gardner): Howard Gardner characterised intelligence as eight distinct types of abilities (linguistic, logical-mathematical, spatial, musical, bodily-kinaesthetic, interpersonal, intrapersonal, naturalist).

6. Emotional Intelligence (Goleman): Intelligence also includes the ability to perceive, manage, and regulate emotions in oneself and others.

Conclusion: In summary, psychologists characterise intelligence as a multi-dimensional construct involving cognitive abilities, problem-solving skills, adaptability, and even emotional competence. It is both a product of heredity and environment.

Given/Context: The question asks about the relative contributions of heredity (nature) and environment (nurture) to intelligence.

Answer:

The debate over nature vs. nurture is one of the oldest in psychology. Both factors contribute significantly to intellectual development.

Role of Heredity (Nature):

• Studies on twins show that identical twins (MZ twins) reared apart have more similar IQ scores than fraternal twins (DZ twins) reared together, indicating a strong genetic component.
• Adopted children's IQ scores correlate more strongly with their biological parents than with their adoptive parents.
• Heritability estimates suggest that genetics accounts for approximately 50–70% of the variance in IQ scores in adults.

Role of Environment (Nurture):

• Children raised in enriched, stimulating environments tend to score higher on intelligence tests.
• Studies show that malnutrition, poverty, lack of education, and poor healthcare can significantly lower intellectual performance.
• The Flynn Effect — the steady rise in average IQ scores across generations worldwide — is attributed to environmental improvements (better nutrition, education, healthcare), not genetic changes.
• Early childhood interventions (e.g., Head Start programmes) have been shown to raise IQ scores in disadvantaged children.

Interaction of Nature and Nurture:

• Intellectual development is best understood as a complex interplay of genetic potential and environmental conditions.
• A child may be born with high genetic potential, but without a supportive environment, that potential may not be realised.
• Conversely, a rich environment can help a child with average genetic endowment achieve higher intellectual performance.

Conclusion: Neither heredity nor environment alone determines intelligence. It is the dynamic interaction between the two that shapes an individual's intellectual capacity. Most psychologists today agree that both nature and nurture are essential and inseparable contributors to intelligence.

What is Self?

The self refers to the totality of an individual's conscious experiences, ideas, thoughts, and feelings with regard to herself or himself. It is the awareness of one's own identity — who one is, what one values, and how one relates to others and the world.

The self has several components:

• Personal self – one's private identity, unique traits, and inner experiences.
• Social self – how one presents oneself in social situations.
• Relational self – identity defined through relationships with others.

Indian Notion of Self vs. Western Notion:

Conclusion: The Western notion emphasises individuality, autonomy, and self-expression, whereas the Indian notion emphasises interconnectedness, duty (dharma), and spiritual transcendence of the ego-self.

Delay of Gratification:

Delay of gratification refers to the ability to resist an immediate, smaller reward in order to obtain a larger, more valuable reward at a later time. It is a form of self-regulation or self-control — the capacity to manage one's impulses and defer immediate pleasure for long-term benefit.

Example: A student who resists watching television and instead studies for an examination is delaying gratification.

The concept was famously studied by Walter Mischel through the Marshmallow Test, in which young children were offered one marshmallow immediately or two marshmallows if they waited.

Importance for Adult Development:

1. Academic and professional success: Children who could delay gratification were found to have better academic performance, higher SAT scores, and greater professional achievements in adulthood.

2. Emotional regulation: The ability to delay gratification is linked to better emotional control, lower levels of frustration, and greater resilience under stress.

3. Social competence: Individuals who can delay gratification tend to be more socially skilled, cooperative, and better at maintaining relationships.

4. Health and well-being: It is associated with healthier lifestyle choices — avoiding substance abuse, maintaining a balanced diet, and exercising regularly.

5. Goal-directed behaviour: It enables individuals to set long-term goals and work persistently towards them, which is essential for adult achievement and fulfilment.

Conclusion: Delay of gratification is a critical component of self-regulation and is considered a strong predictor of positive outcomes across multiple domains of adult life.

Given/Concept: Stress is a central concept in health psychology. It is neither purely a stimulus nor purely a response but an ongoing transactional process.

Definition: Stress is a dynamic, ongoing transactional process between an individual and the environment, in which the individual perceives environmental demands as taxing or exceeding his/her resources and endangering his/her well-being.

Key points:

• Stress arises when there is a mismatch between the demands placed on a person and the resources available to meet those demands.
• The individual's appraisal (cognitive evaluation) of the situation determines whether it is experienced as stressful.
• Stress involves emotional, physiological, cognitive, and behavioural responses.

Examples from daily life:

1. Examination stress: A student who has not prepared well perceives the upcoming board exam as threatening, leading to anxiety, sleeplessness, and inability to concentrate.
2. Work overload: An employee given multiple deadlines simultaneously feels overwhelmed, experiences headaches and irritability.
3. Traffic jam: Being stuck in heavy traffic when already late for an important meeting causes frustration and physiological arousal (increased heart rate).
4. Family conflict: Frequent arguments at home create chronic psychological stress affecting both mental and physical health.

Conclusion: Stress is an unavoidable part of life; what matters is how an individual appraises and copes with the stressful situation.

Symptoms of Stress:

Stress manifests across four dimensions:

Sources (Stressors) of Stress:

1. Life Events: Major changes in life such as death of a loved one, divorce, marriage, job loss, or moving to a new city. Holmes and Rahe's Social Readjustment Rating Scale (SRRS) identified such events as significant stressors.

2. Everyday Hassles: Minor day-to-day irritants such as traffic jams, misplacing keys, arguments with colleagues, financial worries, and household chores. Though small individually, their cumulative effect is significant.

3. Traumatic Events: Extreme, overwhelming events such as natural disasters (floods, earthquakes), accidents, war, or assault that exceed normal coping capacity.

4. Physical and Environmental Stressors: Noise, pollution, extreme temperatures, overcrowding, and natural calamities.

5. Psychological Stressors: Frustration, conflict (approach-approach, avoidance-avoidance, approach-avoidance), internal pressures, and perceived threats.

6. Social Stressors: Interpersonal conflicts, social isolation, discrimination, and peer pressure.

Conclusion: Stressors vary widely in nature and intensity; their impact depends on the individual's appraisal and available coping resources.

Given/Concept: Depression and mania are the two poles of mood disorders. Depression involves a persistent low mood, while mania involves an abnormally elevated mood.

Symptoms of Depression:

• Persistent sad, anxious, or 'empty' mood
• Loss of interest or pleasure in activities once enjoyed (anhedonia)
• Feelings of hopelessness, worthlessness, or excessive guilt
• Fatigue and decreased energy
• Difficulty concentrating, remembering, or making decisions
• Insomnia or hypersomnia (sleeping too much)
• Changes in appetite — significant weight loss or gain
• Psychomotor agitation or retardation (restlessness or slowed movements)
• Recurrent thoughts of death or suicide

Symptoms of Mania:

• Abnormally elevated, expansive, or irritable mood
• Inflated self-esteem or grandiosity
• Decreased need for sleep (feels rested after only 3 hours)
• More talkative than usual; pressure to keep talking
• Flight of ideas — racing thoughts
• Distractibility
• Increase in goal-directed activity (social, occupational, or sexual)
• Excessive involvement in pleasurable activities with high potential for painful consequences (e.g., unrestrained spending, reckless driving)

Conclusion: Depression and mania represent opposite extremes of mood. When both occur in the same individual (alternating), the condition is called Bipolar Disorder.

Psychotherapy is a voluntary relationship between the client and the therapist whose purpose is to help the client solve psychological problems. It is a corrective and helping process that aims at changing maladaptive behaviours, reducing personal distress, and helping the client adapt better to the environment. It is used for problems like anxiety, phobias, depression, relationship difficulties, and other psychological disorders.

Its scope is broad because it includes many different approaches, such as psychodynamic therapy, behaviour therapy, cognitive therapy, humanistic-existential therapy, and alternative therapies. Psychotherapy can help with emotional problems, faulty habits, distorted thinking, and difficulties in social, marital, and occupational adjustment.

The therapeutic relationship or alliance is central to psychotherapy. It is a confidential, interpersonal, dynamic, and professional relationship. The client trusts the therapist and can freely discuss personal problems. The therapist shows acceptance, empathy, genuineness, warmth, and unconditional positive regard. The therapist must keep strict confidentiality and must not exploit the client’s trust. This relationship is important because it becomes the vehicle for change and helps healing occur.

Definition of Attitude:
An attitude is a learned predisposition to respond in a consistently favourable or unfavourable manner with respect to a given object, person, group, issue, or event. It represents a combination of thoughts, feelings, and behavioural tendencies directed towards something.

Components of an Attitude (A-B-C Model):

An attitude has three interrelated components:

1. Affective Component (A — 'A' for Affect/Feeling):

• This refers to the emotional or feeling aspect of an attitude.
• It involves the positive or negative feelings a person has towards the attitude object.
• Example: Feeling happy and excited about environmental conservation.

2. Behavioural Component (B — 'B' for Behaviour):

• This refers to the tendency or predisposition to act in a certain way towards the attitude object.
• It is the action-oriented component.
• Example: Actively participating in cleanliness drives or recycling activities.

3. Cognitive Component (C — 'C' for Cognition/Thought):

• This refers to the beliefs, thoughts, and knowledge a person holds about the attitude object.
• It includes what a person knows or believes to be true.
• Example: Believing that pollution is harmful to health and the environment.

Interrelation of Components:
All three components are interrelated. A change in one component often leads to a change in the others. For instance, if a person gains new knowledge (cognitive) about the dangers of junk food, their feelings (affective) and behaviour (behavioural) towards junk food may also change.

Conclusion: Attitudes are complex mental states that guide our perceptions, feelings, and actions towards objects, people, or situations in our social world.

Given/Concept: Groups can be classified on different bases. Two important classifications are: (i) Formal vs. Informal groups, and (ii) Ingroups vs. Outgroups.

Formal and Informal Groups:

Ingroups and Outgroups:

Contrast Summary: Formal vs. Informal is about how the group is formed (deliberately vs. naturally), whereas Ingroup vs. Outgroup is about the psychological sense of belonging and identity (us vs. them).

Conclusion: Both classifications show that groups differ in their origin, structure, and the psychological impact they have on members' behaviour and attitudes.
