AP Psychology requires memorizing 400+ key terms across 9 units. Good notes organize terms by concept cluster, not just alphabetically, and link each term to a real-world application for FRQ scenarios.
Unit 1–2: Research Methods and Biological Bases
Independent vs. dependent variables, operational definitions, random assignment vs. random sampling, correlation ≠ causation. Neurons and neurotransmission, endocrine system, brain structures (hindbrain/limbic/cortex), neuroplasticity.
Unit 3–4: Sensation, Perception, and Consciousness
Absolute threshold, signal detection theory, sensory adaptation, Weber's Law, Gestalt principles, depth cues. Sleep stages (REM vs. NREM), sleep disorders, consciousness and drugs (depressants, stimulants, hallucinogens).
Unit 5: Learning
Classical conditioning (Pavlov): CS, UCS, UCR, CR, extinction, spontaneous recovery, generalization, discrimination. Operant conditioning (Skinner): reinforcement vs. punishment, schedules (fixed ratio fastest extinction). Observational learning (Bandura): vicarious reinforcement.
Unit 6–7: Cognition and Motivation
Memory encoding/storage/retrieval, proactive and retroactive interference, schemas, heuristics (representativeness, availability, anchoring), intrinsic vs. extrinsic motivation, Maslow's hierarchy, self-determination theory.
Unit 8–9: Emotion, Stress, and Social Psychology
James-Lange, Cannon-Bard, Schachter-Singer theories of emotion. Cognitive appraisal, coping styles, stress and immune function. Conformity (Asch), obedience (Milgram), bystander effect, fundamental attribution error, social facilitation.
