Sample Question 1 — Unit 0
After the school basketball team lost the championship game, a fan claimed, I knew they were going to lose all along because of their weak defense. This fan is demonstrating which error in thinking?
✓ Hindsight Bias
Overconfidence
Confirmation Bias
Sampling Bias
Explanation: Correct: Hindsight Bias. Hindsight bias is the tendency to believe, after learning an outcome, that one would have foreseen it (the I knew it all along phenomenon). The fan claiming they knew the outcome after the game ended fits this perfectly. Overconfidence is being more certain than correct, confirmation bias is seeking information that supports existing beliefs, and sampling bias is a flawed sampling process that produces an unrepresentative sample.
Sample Question 2 — Unit 0
A researcher is conducting a study on political beliefs. She only interviews people she knows agree with her and ignores data from opposition groups. Which obstacle to critical thinking is she displaying?
✓ Confirmation Bias
Hindsight Bias
Skepticism
Humility
Explanation: Correct: Confirmation Bias. Confirmation bias occurs when a person seeks out or only pays attention to information that confirms their preconceptions while ignoring contradictory evidence. Hindsight bias is predicting outcomes after they happen, skepticism is maintaining a doubting attitude, and humility is the willingness to accept when one is wrong.
Sample Question 3 — Unit 1
Identical twins Thomas and James were separated at birth and raised in different countries. Despite this, they both developed a specific phobia of snakes and share nearly identical personality traits. This scenario best supports the influence of:
✓ Heredity
Nurture
Sensory adaptation
Plasticity
Explanation: Correct: Heredity. Identical twins share 100% of their genes. Because they were raised in different environments (separated at birth), their shared phobia and nearly identical personality traits strongly suggest the influence of genetics (heredity) over their upbringing (nurture). Sensory adaptation is a reduction in sensitivity to a constant stimulus, and plasticity refers to the brain's ability to change and adapt.
Sample Question 4 — Unit 1
Researchers find that a specific gene increases the risk of depression, but only in individuals who experience high levels of stress during childhood. This finding highlights the concept of:
✓ Interaction of Heredity and Environment
Natural selection
Eugenics
All-or-nothing principle
Explanation: Correct: Interaction of Heredity and Environment. This finding perfectly illustrates how our genetics (the specific gene) and our environment (childhood stress) work together to influence behavior and mental health. Natural selection is the evolutionary process where traits that aid survival are passed down, eugenics is the controversial practice of selectively breeding humans, and the all-or-nothing principle refers to how a neuron either fires completely or does not fire at all.
Sample Question 5 — Unit 2
While watching a basketball game, Sarah is so focused on the players in white jerseys that she fails to notice a person in a gorilla suit walking across the court. This best illustrates:
✓ Inattentional blindness
Change blindness
Selective attention
The cocktail party effect
Explanation: Correct: Inattentional blindness. Inattentional blindness is failing to see visible objects when our attention is directed elsewhere, such as focusing so hard on the white shirts that you miss the gorilla. Change blindness is failing to notice a change in the environment, selective attention is the actual focusing of conscious awareness on a stimulus, and the cocktail party effect is hearing your name in a crowded room.
Sample Question 6 — Unit 2
Which Gestalt principle best explains why most people report seeing a circle and a rectangle in the image above?
✓ Closure
Figure and ground
Proximity
Similarity
Explanation: Correct Answer: Closure. This principle explains our tendency to fill in the gaps of a disconnected or incomplete figure to perceive a whole, recognizable shape. In an image of a circle and a rectangle made of broken lines, your brain automatically ignores the gaps and closes the shapes to identify them as a circle and a rectangle rather than a collection of random, unrelated lines.
Sample Question 7 — Unit 3
A researcher follows a group of infants from birth until age 20 to see how their temperament changes. This study best addresses which developmental theme?
✓ Stability and change
Nature and nurture
Discontinuous development
Continuous development
Explanation: Correct: Stability and change. The debate over stability and change examines whether early personality traits persist through life or if we become different persons as we age. Following infants to age 20 to track temperament directly studies this. Nature and nurture looks at genetics vs. environment, and continuous/discontinuous looks at whether development is a slow, gradual process or distinct stages.
Sample Question 8 — Unit 3
If a psychologist argues that a child’s personality is shaped entirely by their upbringing and environment rather than their DNA, they are taking a side in which debate?
✓ Nature and nurture
Continuous development
Lifespan development
Chronological development
Explanation: Correct: Nature and nurture. The nature vs. nurture debate focuses on the relative contributions of genetic inheritance (nature/DNA) and environmental factors (nurture/upbringing) to human development. Arguing that upbringing is entirely responsible is taking the nurture side. The other options refer to the speed, stages, or timeline of development rather than the root causes.
Sample Question 9 — Unit 4
Sarah fails her math test. If she has a pessimistic explanatory style, how is she most likely to explain this failure?
✓ I’m just not a math person; I’m never going to be good at anything academic.
The teacher made that test way too hard for anyone to pass.
I didn't study enough for this specific test because I was busy with work.
I was feeling sick that day, so I couldn't focus properly.
Explanation: Correct: I’m just not a math person; I’m never going to be good at anything academic. A pessimistic explanatory style attributes failures to internal (I'm not a math person), stable (never going to be good), and global (anything academic) factors. The other options attribute the failure to external (the teacher), unstable (didn't study enough), or specific (feeling sick) factors.
Sample Question 10 — Unit 4
When David sees a driver cut him off, he yells that the driver is reckless and selfish. Five minutes later, David cuts someone else off but blames it on being late for a job interview. This illustrates:
✓ The actor/observer bias
The self-fulfilling prophecy
Self-efficacy
Internal locus of control
Explanation: Correct: The actor/observer bias. The actor/observer bias is the tendency to attribute one's own actions to external causes (being late for an interview) while attributing others' actions to internal, dispositional causes (they are reckless and selfish). Self-fulfilling prophecy is a belief that causes itself to come true, self-efficacy is belief in one's own abilities, and internal locus of control is believing you control your fate.
Sample Question 11 — Unit 5
While hiking, Jonas spots a bear on the trail. His heart rate immediately spikes, his digestion slows, and he breaks into a sweat. According to the General Adaptation Syndrome, Jonas is currently in which stage?
✓ Alarm reaction phase
Resistance phase
Exhaustion phase
Immunosuppression phase
Explanation: Correct: Alarm reaction phase. According to Hans Selye's General Adaptation Syndrome (GAS), the alarm reaction is the first phase of the stress response. During this stage, your sympathetic nervous system is suddenly activated, mobilizing your body's resources (spiking heart rate, sweating) to meet the immediate threat. The resistance phase is the second stage where the body attempts to cope with the stressor, and the exhaustion phase is the final stage where reserves are depleted.
Sample Question 12 — Unit 5
Rather than studying for a difficult final exam, Marcus decides to play video games to distract himself from his anxiety about failing. This behavior is an example of:
✓ Emotion-focused coping
Problem-focused coping
Biofeedback
The flight-flight-freeze response
Explanation: Correct: Emotion-focused coping. Emotion-focused coping involves attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional needs related to the stress reaction. Marcus is ignoring the actual problem (the test) and instead distracting himself with video games to manage his feelings of anxiety. Problem-focused coping would involve directly tackling the stressor (e.g., actually sitting down to study), and biofeedback is a technique used to gain control over involuntary bodily functions.

💡 Getting the Most Out of This Quiz
Filter by unit while you're first learning material, then switch to "All Units" as your exam gets closer — cumulative practice does a much better job preparing you for how the real AP exam mixes topics together than only drilling one unit at a time. Always read the explanation after answering, even on questions you got right; AP Psych rewards being able to apply a concept to a new scenario, not just recognize a definition, and the explanations are where that skill actually gets built. With 783 questions in the pool, retaking the quiz with a different unit or topic combination will keep giving you fresh material. Once you're comfortable with individual questions, try switching to Question Sets mode — it practices stimulus-based questions grouped around a single study or scenario, exactly how a chunk of the real exam is structured.
