AP® Psychology Cheat Sheets: Units, Flashcards, Quiz & Exam Guide

Unit 2: Cognition

Unit 2 studies how people perceive, think, remember, solve problems, and understand intelligence. The unit is heavily connected to everyday experience, which makes it easier to learn if you create personal examples. When you misread a message because you expected a different word, you are using top-down processing. When you remember the beginning and ending of a list better than the middle, you are seeing the serial position effect. When you think plane crashes are common because you recently saw one in the news, you are using the availability heuristic.

Perception is the interpretation of sensory information. Bottom-up processing begins with raw sensory input. Top-down processing uses prior knowledge and expectations. Gestalt psychologists argued that the mind organizes stimuli into meaningful wholes. Figure-ground separates an object from its background. Proximity groups nearby items. Similarity groups items that look alike. Closure fills gaps. Continuity favors smooth patterns. These principles explain why perception is active organization, not passive recording.

Depth perception depends on cues. Binocular cues require both eyes. Retinal disparity compares the slightly different images received by each eye. Convergence uses the inward movement of the eyes when focusing on nearby objects. Monocular cues can be used with one eye. Linear perspective makes parallel lines seem to meet in the distance. Interposition occurs when one object blocks another. Relative size, texture gradient, relative height, and motion parallax also support depth perception.

Thinking involves concepts, prototypes, schemas, and problem-solving strategies. Concepts are mental categories. A prototype is the best example of a category. A schema is a mental framework that organizes information. Schemas make thinking efficient, but they can also distort memory and perception. For example, a restaurant schema helps you know what to expect when entering a restaurant, but it might also make you remember details that did not actually happen.

Heuristics are shortcuts. They are useful because they save time, but they can produce bias. The availability heuristic estimates likelihood based on how easily examples come to mind. The representativeness heuristic judges likelihood based on similarity to a prototype. Anchoring occurs when the first piece of information influences later judgment. Framing occurs when the wording of a choice changes decisions. These concepts often appear in scenario-based questions.

Memory includes encoding, storage, and retrieval. The Atkinson-Shiffrin model describes sensory memory, short-term memory, and long-term memory. Sensory memory is brief. Short-term memory is limited. Working memory emphasizes active processing. Long-term memory includes explicit and implicit systems. Explicit memory includes episodic memory for personal events and semantic memory for facts. Implicit memory includes procedural memory, priming, and conditioned associations.

Encoding strategies affect later retrieval. Elaborative rehearsal is stronger than maintenance rehearsal because it adds meaning. Chunking groups information. Mnemonics provide retrieval cues. Self-reference connects material to the learner. The levels-of-processing framework says deeper semantic processing creates stronger memory than shallow processing. Retrieval can be improved by cues, context, and state. Context-dependent memory works best when the retrieval environment matches the encoding environment. State-dependent memory works best when internal states match.

Forgetting is not always a simple loss of stored information. Encoding failure means the information was never stored effectively. Storage decay means traces weaken over time. Retrieval failure means the memory may exist but cannot be accessed. Proactive interference occurs when old information disrupts new learning. Retroactive interference occurs when new information disrupts old learning. Memory construction errors occur when the brain fills gaps, changes details, or incorporates misleading information.

Intelligence is another major topic. Spearman's \(g\) factor suggests a general mental ability. Gardner's multiple intelligences theory argues for distinct intellectual abilities. Sternberg's triarchic theory emphasizes analytical, creative, and practical intelligence. Intelligence tests should be judged by reliability, validity, standardization, and fairness. Standardization creates comparison norms. Reliability asks whether the test is consistent. Validity asks whether the test measures what it claims to measure.

Unit 3: Development and Learning

Unit 3 combines lifespan development with learning. Developmental psychology studies how people change physically, cognitively, and socially over time. Learning psychology studies how experience changes behavior. These topics connect naturally because development affects what people can learn, and learning experiences shape development.

Developmental research often uses cross-sectional and longitudinal designs. A cross-sectional study compares different age groups at the same time. It is faster but can be affected by cohort differences. A longitudinal study follows the same individuals over time. It gives stronger evidence of development within individuals, but it takes longer and may suffer from attrition. On the exam, know which design fits a research question and what its limitations are.

Piaget's theory explains cognitive development through stages. In the sensorimotor stage, infants learn through sensory and motor interaction and develop object permanence. In the preoperational stage, children use symbols and language but show egocentrism and struggle with conservation. In the concrete operational stage, children think logically about concrete objects and understand conservation. In the formal operational stage, adolescents can reason abstractly and hypothetically. Even though modern research has revised parts of Piaget's theory, the stages remain important AP® vocabulary.

Vygotsky emphasized social learning and culture. The zone of proximal development is the range of tasks a learner can complete with help but not yet independently. Scaffolding is temporary support from a more knowledgeable person. This theory is useful for explaining tutoring, guided practice, and collaborative learning. A student learning a difficult concept with a teacher's hints is working in the zone of proximal development.

Social-emotional development includes attachment, parenting, identity, morality, and relationships. Ainsworth studied attachment styles using the strange situation. Secure attachment is associated with using the caregiver as a safe base. Avoidant attachment shows limited distress and limited contact seeking. Anxious-resistant attachment shows intense distress and difficulty being comforted. Disorganized attachment shows inconsistent or confused behavior. Harlow's work with monkeys showed the importance of contact comfort.

Language development typically moves from babbling to one-word speech to telegraphic speech to more complete sentences. Chomsky argued that humans have an innate capacity for language. Critical periods suggest that certain developmental windows are especially important for language acquisition. The AP® exam may ask students to connect language development to nature, nurture, social interaction, or cognitive development.

Learning begins with classical conditioning. In classical conditioning, an organism learns an association between stimuli. A neutral stimulus becomes a conditioned stimulus after being paired with an unconditioned stimulus. The conditioned stimulus then produces a conditioned response. Acquisition is the learning phase. Extinction occurs when the conditioned stimulus no longer produces the conditioned response after repeated presentation without the unconditioned stimulus. Spontaneous recovery is the reappearance of the conditioned response after a pause.

Operant conditioning focuses on consequences. Reinforcement increases behavior. Punishment decreases behavior. Positive means something is added. Negative means something is removed. Therefore, positive reinforcement adds a desirable stimulus to increase behavior, while negative reinforcement removes an aversive stimulus to increase behavior. Positive punishment adds an aversive stimulus to decrease behavior, while negative punishment removes a desirable stimulus to decrease behavior. This distinction is one of the most common AP® Psychology traps.

Schedules of reinforcement affect response patterns. Fixed-ratio schedules reinforce after a set number of responses. Variable-ratio schedules reinforce after an unpredictable number of responses and produce high, steady responding. Fixed-interval schedules reinforce the first response after a set time period and often create a scalloped response pattern. Variable-interval schedules reinforce after unpredictable time intervals and produce steady responding.

Observational learning occurs when people learn by watching others. Bandura's research showed that children can imitate modeled behavior, especially when the model is rewarded, admired, or similar to the observer. Observational learning includes attention, retention, reproduction, and motivation. This concept can explain aggression, prosocial behavior, academic habits, fears, and social norms.

Unit 4: Social Psychology and Personality

Unit 4 explains how social situations, attitudes, groups, and personality affect behavior. Social psychology is powerful because it shows that behavior is often shaped by context more than people expect. Personality psychology asks why individuals show stable patterns of thought, emotion, and behavior. Together, these topics help students explain both situational influence and individual differences.

Attribution theory is central. People make dispositional attributions when they explain behavior through internal traits and situational attributions when they explain behavior through external circumstances. The fundamental attribution error is the tendency to overestimate dispositional causes and underestimate situational causes when explaining others' behavior. Actor-observer bias occurs when people explain their own behavior through situations but others' behavior through dispositions. Self-serving bias occurs when people credit themselves for success and blame outside factors for failure.

Attitudes include thoughts, feelings, and behavioral tendencies. Cognitive dissonance occurs when attitudes and actions conflict, creating discomfort. People reduce dissonance by changing attitudes, changing behavior, or rationalizing. Persuasion can use the central route or peripheral route. Central-route persuasion uses logic, evidence, and careful processing. Peripheral-route persuasion uses cues such as attractiveness, emotion, repetition, or credibility without deep analysis.

Conformity and obedience are classic social influence concepts. Conformity involves changing behavior to match group pressure. Asch's line studies demonstrated conformity under social pressure. Obedience involves following authority commands. Milgram's obedience studies demonstrated that ordinary people may comply with authority even when uncomfortable. The exam often asks students to distinguish conformity from obedience and to identify factors that increase each.

Group processes include social facilitation, social loafing, deindividuation, group polarization, and groupthink. Social facilitation improves performance on easy or well-learned tasks in the presence of others but may impair difficult tasks. Social loafing is reduced effort in a group. Deindividuation is reduced self-awareness in group situations. Group polarization strengthens initial group opinions. Groupthink occurs when the desire for harmony suppresses realistic evaluation and dissent.

Prejudice, stereotypes, and discrimination are related but distinct. A stereotype is a belief about a group. Prejudice is an attitude or feeling toward a group. Discrimination is behavior directed at a group. In-group bias favors one's own group. Out-group homogeneity is the tendency to see members of other groups as more similar than they are. The just-world phenomenon is the belief that people get what they deserve, which can lead to blaming victims.

Personality theories explain consistent patterns. Psychodynamic theory emphasizes unconscious motives and conflict. Freud's id seeks immediate pleasure, the superego represents moral rules, and the ego negotiates between desires, morality, and reality. Defense mechanisms reduce anxiety, but they can distort reality. Examples include denial, projection, displacement, rationalization, repression, reaction formation, and sublimation.

Humanistic theories emphasize growth, self-concept, and personal meaning. Rogers emphasized unconditional positive regard, genuineness, and empathy. Social-cognitive theory emphasizes reciprocal determinism, where personal factors, behavior, and environment influence one another. Self-efficacy is a person's belief in their ability to succeed in a specific situation. Trait theory describes personality through stable dimensions. The Big Five traits are openness, conscientiousness, extraversion, agreeableness, and neuroticism.

Motivation and emotion are also included in this unit. Drive-reduction theory focuses on reducing internal tension and maintaining homeostasis. Arousal theory suggests that people seek an optimal level of arousal. Incentive theory emphasizes external rewards. Self-determination theory distinguishes intrinsic motivation from extrinsic motivation and emphasizes autonomy, competence, and relatedness. Emotion includes physiological arousal, expressive behavior, and conscious experience.

Unit 5: Mental and Physical Health

Unit 5 connects stress, health, psychological disorders, diagnosis, treatment, and ethics. The central idea is that mental and physical health are influenced by biological, psychological, and sociocultural factors. A disorder cannot be fully understood through one lens alone. A person experiencing depression, for example, may be affected by neurotransmitter activity, genetic vulnerability, cognitive patterns, social support, stress, culture, and access to treatment.

Stress is the process by which people perceive and respond to challenging or threatening events. Eustress can be motivating, while distress can be harmful. General adaptation syndrome includes alarm, resistance, and exhaustion. Prolonged stress can contribute to immune suppression, hypertension, and other health problems. Coping strategies are often problem-focused or emotion-focused. Problem-focused coping attempts to change the stressor. Emotion-focused coping attempts to manage feelings about the stressor.

Positive psychology studies strengths and well-being. Important ideas include resilience, gratitude, optimism, flow, meaning, and posttraumatic growth. This perspective does not deny suffering; it asks what helps people adapt, recover, and thrive. In an AP® context, positive psychology may appear in stress, coping, motivation, therapy, or health behavior questions.

Psychological disorders are often described through dysfunction, distress, and deviance, but culture matters. A behavior that is unusual in one culture may be normal in another. The DSM and ICD are classification systems. Classification can improve communication and treatment planning, but labels can also create stigma. The biopsychosocial model considers biological, psychological, and sociocultural influences. The diathesis-stress model says that a vulnerability may lead to disorder when combined with stress.

Major disorder categories include neurodevelopmental disorders, schizophrenia spectrum disorders, depressive disorders, bipolar disorders, anxiety disorders, obsessive-compulsive and related disorders, trauma- and stressor-related disorders, dissociative disorders, eating disorders, and personality disorders. AP® Psychology does not require students to diagnose real people. It asks students to recognize defining features and apply concepts carefully to scenarios.

Schizophrenia involves symptoms such as delusions, hallucinations, disorganized speech, disorganized behavior, and negative symptoms. Delusions are false beliefs. Hallucinations are false sensory experiences. Negative symptoms involve reductions in normal behavior, such as flat affect or reduced speech. Depressive disorders involve persistent low mood or loss of interest. Bipolar disorders involve manic or hypomanic episodes. Anxiety disorders involve excessive fear, worry, or avoidance.

Treatment approaches include psychodynamic, humanistic, behavioral, cognitive, cognitive-behavioral, group, family, and biomedical therapies. Psychodynamic therapy seeks insight into unconscious conflicts. Humanistic therapy emphasizes empathy and unconditional positive regard. Behavioral therapy changes maladaptive behaviors through learning principles. Cognitive therapy changes maladaptive thought patterns. Cognitive-behavioral therapy combines thought and behavior change. Biomedical treatments include medication and other biological interventions.

Ethics are essential in both research and treatment. Psychologists should avoid harm, gain informed consent, protect confidentiality, use deception only when justified, debrief participants, and respect human dignity. In therapy, psychologists should maintain boundaries, use evidence-based care, respect culture, and protect confidentiality except in specific safety situations. For FRQs, ethical guidelines must be connected to the study or treatment scenario.

Research methods appear throughout the course but are especially important for the current AP® Psychology exam. Experiments manipulate an independent variable and measure a dependent variable. Random assignment helps create equivalent groups and supports causal conclusions. Random sampling helps generalize to a population. Correlational research measures relationships but cannot prove causation. Surveys, case studies, naturalistic observations, and archival research can provide useful evidence but have limitations.

AP® Psychology FRQ Strategy

The current AP® Psychology free-response section contains two question types: the Article Analysis Question and the Evidence-Based Question. These questions are not simply vocabulary prompts. They require students to apply psychology concepts, evaluate research, interpret data, and write evidence-based explanations. Strong answers are direct, specific, and tied to the prompt.

The Article Analysis Question gives a summarized peer-reviewed source. Students may need to identify a research method, explain a variable, interpret a statistic, discuss an ethical guideline, evaluate generalizability, or apply findings. The biggest mistake is writing generic definitions that do not connect to the article. If the prompt asks about a variable, name the variable in the study. If it asks about an ethical guideline, explain how the guideline applies to the participants or procedure.

The Evidence-Based Question gives multiple summarized sources on a common topic. Students must build an argument using evidence. A strong answer does three things: makes a clear claim, uses specific evidence from the source summaries, and explains how the evidence supports the claim. Do not simply copy a detail from a source. You need to connect the evidence to the argument.

Concept application requires precision. If a prompt asks how social loafing might affect a group project, do not only define social loafing. Explain that an individual may put in less effort because responsibility is diffused across group members. If a prompt asks how the availability heuristic could affect risk perception, explain that a person may overestimate a risk because examples come easily to mind.

Data interpretation requires careful wording. A positive correlation means two variables tend to increase together. A negative correlation means one variable tends to increase as the other decreases. A correlation close to zero means little or no linear relationship. Stronger correlations are closer to \(1\) or \(-1\), while weaker correlations are closer to \(0\). Never say that a correlation proves one variable caused another.

Ethics questions often ask students to connect a guideline to a study. Informed consent means participants know enough about the study to decide whether to participate. Confidentiality protects personal information. Debriefing explains the study after participation, especially when deception was used. Right to withdraw means participants can leave without penalty. Protection from harm means researchers minimize physical and psychological risk.

Use short, clean paragraphs. Each paragraph should answer one part of the prompt. Avoid long introductions. Avoid repeating the question. Avoid vague language such as “it affects them” or “this causes behavior.” Name the behavior, the concept, and the link between them. If you use a term, apply it immediately.

FRQ sentence pattern: “This is an example of [term] because [specific evidence from the scenario] shows [psychological explanation].”

How to Study AP® Psychology With This Cheat Sheet

AP® Psychology has a large vocabulary load, but memorization alone is not enough. A student who can define “operant conditioning” may still lose points if they cannot distinguish reinforcement from punishment in a scenario. A student who can name “random assignment” may still lose points if they confuse it with random sampling. The best study method is active recall plus application.

1. Start with one unit card. Read one cheat-sheet card and underline terms you cannot explain without looking.
2. Turn each term into an example. For every weak term, write one real-life example. Example: “negative reinforcement is when I buckle my seatbelt to stop the car alarm.”
3. Use the flashcards. Say the answer out loud before revealing it. If you miss the card, write the term in a mini notebook with a personal example.
4. Take the quiz without notes. Do not worry about the score at first. Missed questions show what to review.
5. Practice research interpretation daily. Identify the independent variable, dependent variable, sample, population, correlation direction, and ethical issue in short study scenarios.
6. Write AP-style explanations. Use the sentence pattern: term, scenario evidence, psychological explanation.
7. Estimate score readiness. After a timed practice set, use the AP Psychology score calculator to estimate performance.

A seven-day review plan can be simple. Day 1: Unit 1 biology, brain, sleep, sensation. Day 2: Unit 2 cognition and memory. Day 3: Unit 3 development and learning. Day 4: Unit 4 social psychology and personality. Day 5: Unit 5 mental health, treatment, and stress. Day 6: research methods and formulas. Day 7: mixed quiz, flashcards, and FRQ practice. If you have less time, focus on research methods, conditioning, memory, social psychology, and disorders because those topics frequently require application rather than simple recall.

The most efficient AP® Psychology review cycle is: define, apply, compare, retrieve, and write. If you can do those five things for each major term, you are preparing for both multiple choice and free response.
