DESCRIPTION
This comprehensive AP Psychology exam review is designed to strengthen advanced
understanding of the major concepts, theories, research methods, and applications
assessed in AP Psychology. It contains 100+ challenging practice questions and answers
with concise rationales covering biological, cognitive, developmental, social, personality,
clinical, and research domains. Questions emphasize application, interpretation,
experimental reasoning, and scenario-based decision-making rather than simple
memorization. It is suitable for AP Psychology students, advanced high-school learners,
instructors, tutors, and students seeking rigorous exam preparation. Expect realistic
distractors, interdisciplinary scenarios, research interpretation, and higher-order
reasoning. Purchase and instantly get a downloadable and editable PDF.
QUESTIONS 1–150
Question 1
A researcher randomly assigns participants to either sleep for eight hours or remain
awake for 24 hours before completing a memory task. Which feature most directly
allows the researcher to make a causal inference?
,A. Random sampling
B. Random assignment
C. Correlational analysis
D. Operational definition
🔴 Correct Answer: B. Random assignment.
🔵 Explanation: Random assignment helps distribute preexisting participant differences
across experimental conditions, allowing differences in outcomes to be attributed more
confidently to the manipulated variable.
Question 2
A psychologist defines "academic stress" as the score obtained on a standardized 20-
item stress questionnaire. This definition is best described as:
A. A confounding variable
B. An operational definition
C. A placebo effect
D. A sampling bias
🔴 Correct Answer: B. An operational definition.
🔵 Explanation: An operational definition specifies exactly how an abstract construct is
measured or manipulated in a study.
Question 3
A study finds that students who spend more time exercising tend to report lower stress.
Which conclusion is justified?
A. Exercise causes stress reduction.
B. Stress causes students to exercise less.
C. Exercise and reported stress are negatively correlated.
D. Exercise eliminates psychological stress.
🔴 Correct Answer: C. Exercise and reported stress are negatively correlated.
🔵 Explanation: A correlation establishes an association, not causation. The negative
direction means higher exercise levels are associated with lower reported stress.
Question 4
A researcher wants a sample that accurately represents students from every grade level
at a school. Which sampling strategy is most appropriate?
A. Convenience sampling
B. Stratified random sampling
C. Volunteer sampling
D. Case-study sampling
,🔴 Correct Answer: B. Stratified random sampling.
🔵 Explanation: Stratified sampling divides the population into relevant subgroups and
randomly samples from each, improving representation of those subgroups.
Question 5
A statistically significant result is obtained with p < .05. Which interpretation is most
appropriate?
A. The hypothesis has a 95% probability of being true.
B. The finding proves causation.
C. The observed result would be relatively unlikely under the null hypothesis.
D. Ninety-five percent of participants showed the predicted effect.
🔴 Correct Answer: C. The observed result would be relatively unlikely under the null
hypothesis.
🔵 Explanation: A p-value concerns the probability of obtaining results at least as extreme
as those observed assuming the null hypothesis is true; it does not establish the probability
that the hypothesis itself is true.
Question 6
A psychologist observes children interacting on a playground without manipulating
their environment. Which method is being used?
A. Naturalistic observation
B. Experimental manipulation
C. Double-blind procedure
D. Meta-analysis
🔴 Correct Answer: A. Naturalistic observation.
🔵 Explanation: Naturalistic observation involves systematically observing behavior in its
normal setting without experimentally manipulating variables.
Question 7
A participant changes behavior because they know they are being observed. This is
most directly an example of:
A. Observer bias
B. Reactivity
C. Random assignment
D. Regression toward the mean
🔴 Correct Answer: B. Reactivity.
🔵 Explanation: Reactivity occurs when awareness of observation alters a participant's
behavior.
, Question 8
Which situation best illustrates an independent variable?
A. Depression score measured after treatment
B. Number of correct answers on a memory test
C. Type of therapy assigned to participants
D. Participants' age at the beginning of the study
🔴 Correct Answer: C. Type of therapy assigned to participants.
🔵 Explanation: The independent variable is the variable deliberately manipulated or
assigned by the researcher.
Question 9
A researcher finds that two variables have a correlation of −0.91. What does this
indicate?
A. A strong positive causal relationship
B. A weak negative relationship
C. A strong negative linear relationship
D. No meaningful relationship
🔴 Correct Answer: C. A strong negative linear relationship.
🔵 Explanation: Correlations close to −1 indicate strong inverse linear associations.
Question 10
Which research design is particularly useful for studying rare psychological conditions in
depth?
A. Case study
B. Randomized controlled trial
C. Cross-sectional survey
D. Laboratory experiment
🔴 Correct Answer: A. Case study.
🔵 Explanation: Case studies provide intensive examination of an individual, group, or
unusual condition and can generate detailed clinical or theoretical insights.
Question 11
Damage to the hippocampus would most directly interfere with:
A. Formation of many new explicit memories
B. Regulation of heartbeat
C. Production of insulin
D. Basic spinal reflexes
