AP Psychology Unit 2: Cognition

Unit 2 covers cognition: memory, thinking, problem-solving, judgement and language. Heuristics and biases are the highest-yield content here, and they are always tested through a scenario rather than a definition.

What 288 questions on it look like

This is the largest unit in AP Psychology by practice volume — 288 questions against the subject's other units. Weight your revision accordingly.

It spans 8 CED topics, which is wide enough that "I've studied this unit" is not a meaningful statement. Track your accuracy by topic, not by unit.

100% of the questions come with a figure — a graph, diagram or data display. Reading the figure correctly is most of the work before any content knowledge applies.

From the bank

Three real cognition questions

Drawn from the practice pool, not from the mock papers.

Perception · Concept Application · with figure

A student reads a blurry word in a sentence as 'bank' when the surrounding sentence is about money, but reads the same blurry word as 'bank' near a paragraph about a river. What process is influencing perception?

  1. AExpectations from surrounding context guide interpretation of ambiguous sensory input.correct
  2. BAbsolute threshold increases because the letters become physically brighter.
  3. CRetinal disparity allows the student to judge distance with two eyes.
  4. DProcedural memory stores the motor steps for pronouncing words.
Why A is correct

The item tests top-down processing: prior knowledge and context shape perception.

top-down processing explains the evidence in "A student reads a blurry word in a sentence as 'bank' when the surrounding sentence is about money, but reads...". The credited option, "Expectations from surrounding context guide interpretation of ambiguous sensory input", is supported because The same stimulus is interpreted with help from context and expectations. "Procedural memory stores the motor steps for pronouncing words" is a real-looking alternative, but Procedural memory concerns skills and habits, not interpreting an ambiguous word; "Absolute threshold increases because the letters become physically brighter" also fails because The physical brightness is not described as changing. The aim is to connect the concrete evidence to the psychological mechanism, then reject choices that shift the process, time frame, or research logic away from the scenario pattern.

Common mistakes. "Absolute threshold increases because the letters become physically brighter" should be crossed out for this reason: The physical brightness is not described as changing. "Procedural memory stores the motor steps for pronouncing words" is no safer, because procedural memory concerns skills and habits, not interpreting an ambiguous word.

Thinking, Problem-Solving, Judgments, and Decision-Making · Concept Application · with figure

After seeing news coverage of a plane crash, a traveler overestimates the danger of flying even though she has read that severe car accidents are more common. Which cognitive shortcut best explains the judgment?

  1. AConfirmation bias, because she is searching only for evidence supporting a prior belief.
  2. BThe availability heuristic, because a vivid example is easier to bring to mind.correct
  3. CFunctional fixedness, because she cannot imagine a new use for an object.
  4. DAlgorithmic reasoning, because she is following a guaranteed step-by-step rule.
Why B is correct

The traveler relies on mental availability rather than base-rate information.

"After seeing news coverage of a plane crash, a traveler overestimates the danger of flying even though she has..." details toward availability heuristic, not just a familiar Cognition label. The credited option, "The availability heuristic, because a vivid example is easier to bring to mind", is supported because The vivid crash example is mentally available and distorts probability judgment. "Confirmation bias, because she is searching only for evidence supporting a prior..." is a real-looking alternative, but The scenario does not describe selectively searching for supporting evidence; "Functional fixedness, because she cannot imagine a new use for an object" also fails because No object-use problem is involved. The aim is to connect the concrete evidence to the psychological mechanism, then reject choices that shift the process, time frame, or research logic away from the scenario pattern.

Common mistakes. confirmation bias and functional fixedness are not interchangeable with availability heuristic. One fails because the scenario does not describe selectively searching for supporting evidence; the other fails because no object-use problem is involved.

Introduction to Memory · Concept Application · with figure

A server repeats a six-digit table number silently while walking across a restaurant. When another customer asks a question, the server loses the number before entering it. Which memory system was most directly overloaded?

  1. AImplicit memory, because the number was stored as an unconscious skill.
  2. BLong-term potentiation, because synapses permanently stopped changing.
  3. CWorking memory: active maintenance was interrupted.correct
  4. DFlashbulb memory, because the event was emotionally shocking and durable.
Why C is correct

The interruption disrupts temporary active maintenance.

working memory is the mechanism that makes "A server repeats a six-digit table number silently while walking across a restaurant." coherent. The credited option, "Working memory, because brief active maintenance was interrupted by a competing task", is supported because The server was actively maintaining information briefly, which fits working memory. "Long-term potentiation, because synapses permanently stopped changing" is a real-looking alternative, but Long-term potentiation concerns neural strengthening, not losing a just-repeated number; "Flashbulb memory, because the event was emotionally shocking and durable" also fails because The situation is ordinary and temporary, not a vivid durable event. The aim is to connect the concrete evidence to the psychological mechanism, then reject choices that shift the process, time frame, or research logic away from the scenario pattern.

Common mistakes. "Long-term potentiation, because synapses permanently stopped changing" answers a different issue from the one being tested. "Flashbulb memory, because the event was emotionally shocking and durable" also drifts, since the situation is ordinary and temporary, not a vivid durable event.

FAQ

Cognition questions

What is the difference between availability and representativeness?

Availability judges likelihood by how easily examples come to mind. Representativeness judges it by how well a case matches a stereotype, ignoring base rates.

How is memory tested?

Through the stage that failed — encoding, storage or retrieval — given a described situation.
