Theories of Personality – Comprehensive Bullet-Point Notes

Personality: Core Definition and Related Constructs

• Personality (A-B-C framework): unique, relatively stable patterns of
  • Affect (feelings)
  • Behavior (actions)
  • Cognition (thoughts)
• Embedded concepts
  • Character → social/moral value judgments on behavior ("good/ bad")
  • Temperament → biologically-based, enduring emotional reactivity present at birth (e.g., a "naturally grouchy" infant)
• Interaction statement: Temperament + Character ⇢ shape and color overall personality

Grand Theoretical Families

• Psychodynamic (Freud ➝ Neo-Freudians): unconscious forces & early experience
• Behavioral (Watson, Skinner): learned stimulus–response habits
• Social-Cognitive (Bandura, Rotter): reciprocal interaction of learning, cognition, and environment
• Humanistic (Rogers, Maslow): conscious growth, freedom, self-actualization
• Trait / Dispositional (Allport ➝ Big 5): describe, measure, and predict via stable characteristics

Psychodynamic Perspective (Freud)

Historical Context

• Victorian era sexual repression ➝ heavy social constraints; many clientele = upper-class women reporting hysteria/sexual conflict ➝ shaped theory

Structure of the Mind

• Conscious – current awareness (thoughts, perceptions)
• Pre-conscious – easily retrievable memories
• Unconscious – vast store of repressed thoughts, desires, memories; primary driver of behavior and dreams

Structural Model of Personality

• Id ("It")
  • Entirely unconscious; innate at birth
  • Operates on Pleasure Principle (immediate gratification, survival instincts, libido)
  • Imagery: devil on shoulder saying “I want it NOW.”
• Superego ("Over-I")
  • Moral compass internalized from parents/culture; contains Conscience
  • Operates on Morality Principle (strives for perfection; produces pride or guilt)
• Ego ("I")
  • Mostly conscious executive/mediator; develops during toddlerhood
  • Operates on Reality Principle (delay gratification until safe/ appropriate)

Psychic Energy, Endopsychic Conflict, & Anxiety

• Limited reservoir of "psychic energy" $E_{psy}$ shared by id–ego–superego → constant competition
• Conflicts create anxiety (e.g., $\text{Id}: “rob the bank” \; vs \; \text{Superego}: “that is wrong”$)
• Defense Mechanisms (Table 13.1) = unconscious distortions mobilized by Ego to reduce anxiety
  • Denial, Repression, Rationalization, Projection, Reaction Formation, Displacement, Regression, Identification, Compensation, Sublimation
  • Example: Displacement—after boss reprimands, Sandra fights with spouse (safer target)

Psychosexual Stages & Potential Fixations

Neo-Freudians: Key Revisions

• Carl Jung
  • Added Collective Unconscious—shared species memory; contains Archetypes (Anima/Animus, Shadow, Persona, etc.)
• Alfred Adler
  • Driving force = Inferiority ➝ Striving for Superiority; introduced Birth-Order Theory (1st born overachievers, middles competitive, babies pampered)
• Karen Horney
  • Rejected penis envy; proposed Womb Envy & Basic Anxiety (hostile world); described Neurotic Coping Styles (clingy, aggressive, detached)
• Erik Erikson
  • 8 Psyco-social crises across lifespan (emphasis on social rather than sexual factors)

Contemporary Evaluation

• Empirical support: existence of unconscious processing & certain defenses
• Critiques: non-falsifiable, small biased sample (wealthy Viennese women), overemphasis on sexuality

Learning Views of Personality

Strict Behaviorism (Watson, Skinner)

• Personality = bundle of Habits (conditioned S-R bonds)
  • Classical conditioning: Little Albert’s learned fear
  • Operant conditioning: Skinner box—reinforcement histories produce traits (e.g., "outspoken" = history of social reinforcement for talking)
• Limitation: ignores cognition & social context

Social-Cognitive Approach

Bandura: Reciprocal Determinism & Self-Efficacy

• Triadic causation: Behavior ↔ Environment ↔ Personal/Cognitive factors (Figure 13.2)
• Self-Efficacy: belief in one’s capability for a behavior in a context (distinct from self-esteem)
  • High $SE$ → persistence & adaptive coping

Rotter: Social Learning Theory

• Behavior chosen via Expectancy (subjective probability of outcome) & Reinforcement Value (desirability)
• Locus of Control (LoC)
  • Internal: outcomes = personal control ➝ proactive coping, better health
  • External: outcomes = luck/fate ➝ learned helplessness risk

Evidence & Critique

• Strong experimental backing for modeling, expectancies, and $SE$
• Critics: still underestimates unconscious / biological influences; lab emphasis may reduce ecological validity

Humanistic (Third-Force) Perspective

Core Propositions (Rogers, Maslow)

• Humans possess Free Will and innate drive toward Self-Actualization (fulfilling capacities)
• Development hinges on Self-Concept accuracy & congruence

Rogers’ Constructs

• Real Self (current traits/ abilities) vs Ideal Self (aspirations shaped by significant others)
  • Large incongruence ⇒ anxiety, neurotic behavior (Figure 13.3)
• Positive Regard
  • Unconditional PR: acceptance w/o strings ⇒ fosters congruence & Fully Functioning Person
  • Conditional PR: worth only if conditions met ⇒ fosters "conditions of worth" & defensiveness

Appraisal

• Contributions: client-centered therapy; positive psychology roots
• Criticisms: overly optimistic, difficult to test objectively (self-actualization operationalization)

Trait Approaches

Allport

• Catalogued $\approx 200$ dictionary traits; viewed as neurologically based dispositions

Cattell

• Employed Factor Analysis ➝ distilled to 16 Source Traits (16PF inventory)
  • Distinction:
  • Surface Traits (observable: "shy, quiet")
  • Source Traits (underlying: "introversion")

Five-Factor Model ("Big 5" / O.C.E.A.N.)

1. Openness – inventive/curious vs. conventional
2. Conscientiousness – organized/dependable vs. careless
3. Extraversion – outgoing/energetic vs. reserved
4. Agreeableness – friendly/compassionate vs. antagonistic
5. Neuroticism – sensitive/nervous vs. secure

• Traits are statistically independent; predict diverse life outcomes (job success, health, relationships)
• Trait-Situation Interaction: situational cues modulate trait expression (e.g., introvert acting sociably at work)

Biological Bases / Heritability (Learning Objective 13.12-13.13)

• Twin & Adoption Studies show $h^{2} \approx 0.40-0.60$ for major traits
  • Monozygotic twins raised apart still correlate > dizygotic together ⇒ genetic influence
• Genes set range; environment funnels expression (gene–environment correlation & interaction)

Measuring Personality in Practice

Interviews (often psychoanalytic & humanistic)

• Structured or unstructured conversation; susceptible to Halo Effect & deliberate deception

Behavioral Assessments (behavioral / social-cognitive clinicians)

• Direct Observation, Rating Scales, Frequency Counts, role-plays
• Issues: observer bias, reactivity (Hawthorne effect), poor generalization across settings

Personality Inventories (trait theorists)

• Objective, standardized items (T/F, Likert)
  • 16PF, NEO-PI-3 (Big 5), MMPI-2-RF (clinical patterns), MBTI (Jungian types)
• Built-in validity scales reduce but do not eliminate faking

Projective Tests (psychoanalytic tradition)

• Ambiguous stimuli → projection of unconscious material
  • Rorschach inkblots
  • TAT picture stories
• Problems: scoring subjectivity, low reliability/validity, cultural bias; still valuable for ice-breaking or hypothesis generation

Integrative Review & Practical Connections

• No single model fully explains personality; contemporary consensus favors biopsychosocial integration:
  • Bio: genetic temperaments, brain systems (e.g., dopamine ➝ extraversion)
  • Psycho: cognitive schemas, defense use
  • Social: family style, culture, learning history
• Ethical / applied implications
  • Hiring & clinical decisions must weigh test validity & fairness (e.g., avoid sole reliance on MBTI for selection)
  • Personality understanding informs therapeutic match, classroom management, leadership, marketing
• Philosophical note: tension between determinism (id, conditioning, genes) and free will (humanistic choice); exam essays may invite you to reconcile

Quick Study Checklist

• Draw Freud’s topographic & structural models; practice matching defense mechanisms to scenarios
• Be able to sequence psychosexual stages with ages and fixations
• Diagram Bandura’s triadic reciprocity and give one classroom or workplace example
• Memorize Big 5 definitions and high/low descriptors; think of a celebrity exemplar for each
• Contrast unconditional vs. conditional positive regard; link to parenting styles
• List strengths/weaknesses of each assessment method (reliability, validity, bias)
• Review twin-study methodology: $r<em>{MZ} > r</em>{DZ}$ logic for heritability estimation
