Q130 - Personality: Determinants and Development (7 Marks)

1. Definition of Personality

Personality is sum total of ways in which an individual reacts and interacts with others. It is dynamic, organised, relatively stable pattern of traits, motives, values and behaviours.

• Robbins: “Sum total of ways in which an individual reacts and interacts with others”
• Gordon Allport: “Dynamic organization within the individual of psychophysical systems that determine unique adjustments to environment”

Includes both observable behaviour and inner cognitive-affective structures.

2. Nature / Characteristics

• Unique & stable, yet can change with major experiences
• Influences behaviour, perception, motivation
• Product of heredity + environment
• Can be measured (Big Five, MBTI, 16PF)

3. Determinants of Personality

Personality = Heredity × Environment × Situation. Major determinants:

A. Heredity / Biological Factors

• Genetic transmission: physique, temperament, intelligence, sex, nervous system
• Twin studies show 40-50% variance due to heredity
• Hormones, neurotransmitters affect emotionality
• Physique (Kretschmer, Sheldon) links body type to temperament, though weak

B. Environment – Most Significant

1. Family: Parental style, birth order, socio-economic status. Authoritarian vs democratic parenting shapes confidence
2. Socialisation: School, peers, religion
3. Culture: Collectivist (India) vs Individualist (USA) shapes values; e.g., “jugaad” adaptability
4. Work Experience & Organisation: Role, success/failure, organisational culture modifies traits (e.g., military discipline)
5. Life Experiences: Trauma, achievements, migration

C. Situational Factors

• Personality expressed differently per situation (e.g., introvert becomes assertive as union leader)
• Trait activation theory: Situation triggers latent trait. Personality is not fully fixed – interactionist view (Lewin: $B = f(P, E)$)

4. Development of Personality - Major Theories (Brief)

Theory	View of Development
Psychoanalytic (Freud)	Id-Ego-Superego, oral-anal-phallic-latency-genital stages; early childhood critical
Social Learning (Bandura)	Observation, reinforcement, self-efficacy; personality learned
Trait Theories (Allport, Cattell, Big Five)	5 broad traits: OCEAN – Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism – relatively stable, predicts job performance (Conscientiousness best predictor)
Erikson’s Psychosocial	8 stages (trust vs mistrust ... integrity vs despair) – lifelong development
Heredity vs Development: Continuity and change – core traits stable after 30, but skills/roles evolve with experience

5. Determinants vs Development - Linkage

Heredity sets potential, environment actualises it through social learning and reinforcement. Example: Child with high intellectual potential (heredity) becomes engineer only if family/school provides education (environment) and given opportunities (situation).

6. Organisational Implications

• Person-Job fit: Conscientiousness → quality jobs; Extraversion → sales
• Holland’s Person-Job fit – 6 types (RIASEC) match vocation
• Training can shape attitudes, but core traits hard to change → select personality, train skill

Conclusion for 7M: Define personality, list heredity + 4-5 environmental factors with 1-line example, add situational factor, mention Big Five as measure. Diagram: Three concentric circles – Core (heredity) → Environment → Situation influencing personality, or simply formula $Personality = Heredity + Environment + Situation$.
