What are personality theories?

Personality refers to the patterns of thought, feeling and behavior that stay relatively consistent across time and situations. Gordon Allport (1937) defined it as "the dynamic organization within the individual of those psychophysical systems that determine his unique adjustments to his environment." Personality theories try to explain what these differences consist of, where they come from and whether they can change.

Major approaches

Psychoanalytic

Freud explained personality through conflicts among the id, ego and superego, the unconscious and early childhood experience. Neo-Freudians such as Jung, Adler and Erikson placed more weight on social factors and lifespan development.

Trait

Trait theories describe personality along measurable dimensions. Allport and Odbert extracted about 18,000 personality-related words from an English dictionary; Cattell used factor analysis to arrive at 16 factors; Eysenck proposed extraversion, neuroticism and psychoticism. Today's dominant model is the Big Five (openness, conscientiousness, extraversion, agreeableness, neuroticism), standardized in Costa and McCrae's NEO inventories.

Humanistic

Rogers and Maslow saw people as growth-oriented and placed the self-concept and the actualizing tendency at the center of personality.

Social-cognitive

Bandura proposed reciprocal determinism among person, behavior and environment, along with self-efficacy. Walter Mischel's 1968 critique that behavior varies greatly across situations sparked the person-situation debate; he later proposed the cognitive-affective personality system (CAPS), which treats personality as stable "if-then" patterns.

Criticisms and debates

  • Psychoanalytic claims are hard to test empirically.
  • Trait models describe how people differ better than they explain why.
  • Twin studies typically estimate the heritability of personality traits at roughly 40-50%, pointing to both genetic and environmental influences.
