Content Knowledge for Psychology Licensure
This domain tests the breadth of psychology required for licensure: biological bases, sensation/perception, learning, memory, cognition, development, social, personality, motivation/emotion, abnormal, treatment, and research methods/ethics. The exam rewards integrated understanding and applied reasoning, not isolated fact recall. It emphasizes applying concepts to clinical, educational, and research scenarios.
Core Rules and Concepts
- Biological bases: Neurotransmitters (dopamine-reward/motor; serotonin-mood/sleep; GABA-inhibition) and structures (amygdala-fear; hippocampus-memory consolidation; prefrontal cortex-executive control).
- Sensation/perception: Absolute threshold (detect 50% of time), Weber’s law (JND proportional to stimulus), Gestalt principles (proximity, similarity, closure).
- Learning: Classical conditioning (CS+US→CR), operant conditioning (reinforcement increases behavior; punishment decreases), schedules of reinforcement (fixed/variable, ratio/interval).
- Memory/cognition: Working memory (limited capacity), long-term memory (explicit/implicit), encoding specificity; heuristics (availability, representativeness) and biases; problem solving (algorithms vs heuristics; confirmation bias).
- Development: Piaget’s stages (sensorimotor, preoperational, concrete operational, formal operational) and Erikson’s psychosocial crises; know ages and hallmark abilities.
- Social/personality: Fundamental attribution error, conformity (Asch), obedience (Milgram), cognitive dissonance; Big Five (OCEAN); defense mechanisms.
- Motivation/emotion: Intrinsic vs extrinsic motivation; Yerkes-Dodson law (moderate arousal often optimal for complex tasks).
- History/systems: Structuralism (Wundt/Titchener), functionalism (James), behaviorism (Watson/Skinner), psychoanalysis (Freud).
- Abnormal/treatment: DSM-5-TR criteria require duration, impairment, and exclusion; CBT targets maladaptive thoughts; SSRIs are first-line for many anxiety/depressive disorders.
- Research methods/ethics: Reliability (consistency), validity (accuracy), internal validity (causal inference), external validity (generalizability); informed consent, debriefing, IRB approval.
Worked Example
A study finds r = .45 between daily screen time and anxiety in adolescents. A candidate concludes screen time causes anxiety. Reasoning: correlation does not establish causation; a third variable (e.g., poor sleep) could explain both; temporal precedence is unknown. A randomized controlled trial or longitudinal design with covariates is needed before causal claims.
Traps That Cost Marks
- Confusing negative reinforcement (removing aversive stimulus to increase behavior) with punishment.
- Equating OCD (obsessions/compulsions) with OCPD (pervasive perfectionism).
- Ignoring base rates in diagnostic reasoning.
- Assuming reliability guarantees validity.
- Applying DSM criteria without checking duration/impairment.
