Unit 4: Social Psychology and Personality
Explore Social Influences, Theories of Personality, Motivation & Emotion | AP® Psychology
Unlock the foundations of how we perceive others, form attitudes, navigate social settings, and express our unique personalities—with powerful models, clearly rendered math, and exam strategies!
📚 Unit Overview
Unit 4: Social Psychology and Personality investigates how people understand, influence, and relate to each other. You’ll also master personality theory, plus the math and science of motivation and emotion.
Study seven essential topics, from attribution and person perception to the diversity of personality models, motivation, and emotional processes—all with visual clarity and exam-ready organization.
🎯 Key Concepts You'll Master
- Attribution Theory: Internal vs. external causes (\( B = f(P, S) \)), fundamental attribution error
- Attitude Formation & Change: Cognitive dissonance theory, persuasion models, attitude-behavior links
- Social Situations: Conformity, obedience, group dynamics, social facilitation/inhibition (\( P = f(G,E) \))
- Personality Theories: Psychodynamic (Freud), humanistic (Maslow’s hierarchy), trait theory (Big Five: OCEAN), social-cognitive (Bandura: reciprocal determinism)
- Motivation: Drive-reduction, incentive, arousal theories (\( Y = k \sqrt{A} \)), Maslow’s hierarchy, goal orientation
- Emotion: Theories (James-Lange, Cannon-Bard, Schachter-Singer), emotion formulas (\( E = f(A,S,P) \)), facial feedback, stress responses
🎓 Learning Objectives
By the end of Unit 4, you will be able to:
- Explain how people interpret behavior using attribution models
- Analyze how attitudes form and change via cognitive, emotional, and behavioral routes
- Diagram social influences: conformity, group process, obedience
- Compare psychodynamic, humanistic, trait, and social-cognitive theories of personality
- Model motivational processes and relate behavior to key equations
- Describe and compare major emotion theories and formulas
- Apply concepts to MCQ and FRQ-style AP® Psychology questions

Attribution Theory and Person Perception
Dive into internal vs. external causes, fundamental attribution error, and classic person perception models (\( B = f(P, S) \)).
Explore Topic 4.1 →Attitude Formation and Attitude Change
Learn about cognitive dissonance, persuasion techniques, attitude-behavior consistency, and change mechanisms.
Explore Topic 4.2 →Psychology of Social Situations
Examine conformity, obedience, groupthink, facilitation/inhibition, and performance formulas (\( P = f(G, E) \)).
Explore Topic 4.3 →Psychodynamic and Humanistic Theories of Personality
Contrast Freud’s theory with Maslow and Rogers’ views, focusing on unconscious motives, self-actualization, and hierarchy of needs.
Explore Topic 4.4 →Social-Cognitive and Trait Theories of Personality
Study the Big Five (OCEAN), social-cognitive models (reciprocal determinism), and personality assessment strategies.
Explore Topic 4.5 →Motivation
Explore drive-reduction, incentives, Maslow’s hierarchy, goal orientation, and arousal formula (\( Y = k \sqrt{A} \)).
Explore Topic 4.6 →Emotion
Unpack James-Lange, Cannon-Bard, and Schachter-Singer theories; model emotions (\( E = f(A,S,P) \)), and analyze facial feedback.
Explore Topic 4.7 →🌟 Why Unit 4 Matters
Social psychology and personality highlight the science of social influence, individuality, and why we behave as we do. These concepts are core to exam success and understanding human diversity.
