Personality and its Theories
Overview
Personality refers to the unique, relatively stable pattern of thoughts, feelings, and behaviours that distinguishes one individual from another. For Bihar TET, this topic bridges Child Development with classroom practice — understanding personality helps teachers recognise why children behave differently and how to support diverse learners.
The syllabus specifically requires knowledge of three major theorists: **Gordon Allport** (trait approach), **Raymond Cattell** (factor-analytic traits), and **Sigmund Freud** (psychoanalytic theory). Questions typically test definitions, key concepts from each theory, and practical applications in educational settings. Expect 2–4 questions on this topic, often comparing theories or asking about assessment methods.
Mastering this topic also supports answers on individual differences, emotional development, and inclusive education — making it a high-value area for Paper I and Paper II candidates.

Key Concepts
- **Personality** is the dynamic organisation within an individual of psychophysical systems that determine unique adjustment to the environment (Allport's definition).
- **Trait theories** assume personality consists of stable characteristics (traits) that can be identified, measured, and used to predict behaviour across situations.
- **Allport's trait hierarchy**: Cardinal traits (rare, dominating), central traits (5–10 core characteristics), and secondary traits (situation-specific preferences).
- **Cattell's 16 Personality Factors (16PF)**: Using factor analysis, Cattell identified 16 source traits underlying surface behaviours — measured through standardised questionnaires.
- **Freud's structure of personality**: Id (pleasure principle, unconscious desires), Ego (reality principle, mediator), and Superego (moral conscience, internalised values).
- **Freud's psychosexual stages**: Oral → Anal → Phallic → Latency → Genital — fixation at any stage affects adult personality.
- **Defence mechanisms** (Freud): Unconscious strategies like repression, denial, projection, and rationalisation that protect the ego from anxiety.
- **Nature vs Nurture in personality**: All three theorists acknowledge both heredity and environment, but differ in emphasis — Freud stresses early childhood experiences; trait theorists emphasise biological predispositions.
