Exam Study Guide (OCR Document)
Overview
This study guide provides a complete summary of the most essential topics covered in an introductory
psychology course. It is designed to support students preparing for midterms, finals, AP exams, CLEP
exams, or foundational psychology assessments. The content is structured in clear sections, focusing on
concepts that frequently appear in academic tests.
1. Foundations of Psychology
What Is Psychology?
Psychology is the scientific study of behavior and mental processes. It integrates biological, cognitive,
emotional, and social perspectives to understand how humans think and act.
Major Approaches in Psychology
1. Biological Perspective: Focuses on brain structures, neurotransmitters, genetics.
2. Behavioral Perspective: Emphasizes observable behavior and conditioning (Pavlov, Skinner).
3. Cognitive Perspective: Examines thought processes, memory, problem solving.
4. Psychoanalytic Perspective: Based on Freud’s theories of unconscious drives.
5. Humanistic Perspective: Highlights free will, personal growth (Rogers, Maslow).
6. Sociocultural Perspective: How culture and environment influence behavior.
7. Evolutionary Perspective: Behavior as a result of natural selection.
Research Methods
• Experiments: Determine causal relationships; include independent and dependent variables.
• Correlational Studies: Examine relationships but do not show causation.
• Naturalistic Observation: Real-world behavior, minimal control.
• Case Studies: In-depth investigation of individuals.
• Surveys: Large data collection through self-report.
Key concept: Correlation does not imply causation.
2. Biological Bases of Behavior
Neurons and Neurotransmission
• Neuron: Basic unit of the nervous system.
• Neurotransmitters: Chemical messengers (dopamine, serotonin, acetylcholine, GABA).
• Action Potential: Electrical impulse that travels down a neuron.

, Major Brain Structures
• Frontal lobe: Decision-making, planning, personality.
• Parietal lobe: Sensory processing.
• Temporal lobe: Hearing, memory.
• Occipital lobe: Vision.
• Amygdala: Emotion, fear responses.
• Hippocampus: Memory formation.
• Hypothalamus: Hunger, thirst, body regulation.
Nervous System Divisions
• Central Nervous System (CNS): Brain + spinal cord.
• Peripheral Nervous System (PNS) including:
– Somatic: Voluntary movements.
– Autonomic: Involuntary functions (sympathetic vs. parasympathetic).
3. Sensation and Perception
Sensation
Detection of stimuli through sensory organs (eyes, ears, nose, skin).
Perception
Interpretation of sensory information by the brain.
Key Concepts
• Absolute threshold: Minimum stimulation needed to detect a stimulus.
• Difference threshold (JND): Minimum change to detect a difference.
• Top-down vs. bottom-up processing: Expectations vs. raw data.
• Gestalt principles: Proximity, similarity, closure, continuity.
4. Learning
Classical Conditioning (Pavlov)
Learning through association.
- UCS → UCR (food → salivation)
- CS → CR (bell → salivation)
Operant Conditioning (Skinner)
Learning through consequences.
- Reinforcement: Increases behavior.
- Punishment: Decreases behavior.
- Schedules of reinforcement: Fixed ratio, variable ratio, fixed interval, variable interval.
