MCAT Cognition and Problem Solving Practice Questions

By StudyStore · Published 2026-11-02 · 8 original questions · about 12 min

Free MCAT cognition practice questions on Piaget's stages, heuristics, biases, problem-solving barriers, decision making and intelligence theories, with full explanations.

Quick concept primer

Cognition questions usually hand you a short scenario and ask you to name the process at work. For development, match the child's age and error to a Piaget stage: sensorimotor (object permanence develops), preoperational (egocentrism, no conservation), concrete operational (conservation, logic about real objects) and formal operational (abstract and hypothetical reasoning). For problem solving and judgment, decide whether the person used a shortcut (a heuristic), held on to a belief despite evidence (a bias), or got stuck on one way of seeing an object or method (fixation).

Intelligence questions test who proposed what: Spearman's general factor g, Gardner's multiple intelligences, Sternberg's triarchic theory, and the split between fluid and crystallized intelligence. The 6B Cognition, Memory and Consciousness pack adds flashcards and more questions across attention, memory, sleep and language, and the free sampler lets you try the format first.

Traps: the availability heuristic is about ease of recall, while representativeness is about matching a prototype. Confirmation bias is seeking supporting evidence; belief perseverance is keeping a belief after its evidence is discredited. Functional fixedness concerns an object's usual use, while a mental set concerns a habitual strategy.

Question 1

A researcher pours juice from a short, wide cup into a tall, narrow cup while a child watches. The child now insists the tall cup holds more juice. The child also cannot yet explain the scene from the viewpoint of a doll seated across the table. Which Piaget stage best fits this child?

  1. Preoperational
  2. Sensorimotor
  3. Concrete operational
  4. Formal operational
Show answer and explanation

Answer: A. Preoperational

Failing conservation of liquid volume and showing egocentrism are the classic markers of the preoperational stage, roughly ages 2 to 7. Sensorimotor infants are still building object permanence, concrete operational children pass conservation tasks, and formal operational thinking adds abstract reasoning.

Question 2

After watching several news reports about shark attacks, a traveler rates swimming in the ocean as far more dangerous than driving to the beach, even though she knows driving causes many more deaths each year. Which process best explains her judgment?

  1. Representativeness heuristic
  2. Anchoring
  3. Availability heuristic
  4. Belief perseverance
Show answer and explanation

Answer: C. Availability heuristic

She judges risk by how easily vivid examples come to mind, which is the availability heuristic. Representativeness involves matching a case to a prototype, anchoring involves adjusting too little from a starting value, and belief perseverance involves clinging to a belief after its evidence is discredited.

Question 3

In a lab task, volunteers must mount a small lamp on a corkboard wall using only a box of pushpins and some matches. In one condition the pins are inside the box; in the other the pins sit next to an empty box. Results:

ConditionSolved within 10 minutesTotal participants
Pins inside box2050
Pins beside empty box4350

By how many percentage points did the solution rate differ, and what best explains the difference?

  1. 23 points; mental set
  2. 46 points; confirmation bias
  3. 23 points; functional fixedness
  4. 46 points; functional fixedness
Show answer and explanation

Answer: D. 46 points; functional fixedness

The rates are 20/50 = 40 percent and 43/50 = 86 percent, a gap of 46 points. When the box holds pins, people see it only as a container and miss its use as a shelf, which is functional fixedness. A mental set is a habitual strategy, not a fixed view of an object's use, and 23 is the raw count difference, not a percentage.

Question 4

A school psychologist in 1920 tests a girl who is 12 years old. Her test results match what most 9-year-olds achieve. Under the early ratio formula, IQ equals mental age divided by chronological age, times 100. What IQ would she be given?

  1. 133
  2. 75
  3. 97
  4. 300
Show answer and explanation

Answer: B. 75

Her mental age is 9 and her chronological age is 12, so 9 divided by 12, times 100, gives 75. A score of 133 comes from inverting the ratio (12/9), 97 comes from subtracting the 3-year gap from 100, and 300 comes from multiplying the gap by 100.

Question 5

Gardner's theory of multiple intelligences includes all of the following EXCEPT:

  1. emotional intelligence
  2. bodily-kinesthetic intelligence
  3. interpersonal intelligence
  4. musical intelligence
Show answer and explanation

Answer: A. emotional intelligence

Emotional intelligence, the ability to perceive and manage emotions, was developed by other researchers and is not one of Gardner's intelligences. Bodily-kinesthetic, interpersonal and musical intelligence are all on Gardner's list, along with linguistic, logical-mathematical, spatial, intrapersonal and naturalist, among others.

Question 6

Two groups of patients read about the same surgery. One group is told that 92 of every 100 patients are alive a year later; the other is told that 8 of every 100 patients die within a year. The first group is much more likely to choose surgery. This is an example of:

  1. the sunk cost effect
  2. the representativeness heuristic
  3. the framing effect
  4. overconfidence
Show answer and explanation

Answer: C. the framing effect

The two descriptions give identical outcomes (92 survive, 8 die), yet the survival wording draws more acceptance, which defines the framing effect. Sunk cost involves past investment, representativeness involves prototype matching, and overconfidence involves overrating the accuracy of one's own judgments.

Question 7

A student believes a supplement improves his memory because of a study he read. Later he learns the study was retracted for fabricated data, but he keeps taking the supplement and still says it works. Which term best describes this?

  1. Confirmation bias
  2. Hindsight bias
  3. Mental set
  4. Belief perseverance
Show answer and explanation

Answer: D. Belief perseverance

Keeping a belief after the evidence that created it has been discredited is belief perseverance. Confirmation bias would mean actively seeking out supporting evidence, hindsight bias means thinking an outcome was predictable after the fact, and a mental set is a habitual problem-solving approach.

Question 8

A cognitive aging study compares adults aged 25 and 70 on two tests: solving novel abstract puzzles under time pressure, and defining vocabulary words. Which pattern is most consistent with the distinction between fluid and crystallized intelligence?

  1. Both scores fall by a similar amount in the older group
  2. Puzzle scores are lower in the older group, while vocabulary scores are similar or higher
  3. Vocabulary scores are lower in the older group, while puzzle scores are similar
  4. Neither score differs, because intelligence is fixed after adolescence
Show answer and explanation

Answer: B. Puzzle scores are lower in the older group, while vocabulary scores are similar or higher

Fluid intelligence, fast reasoning about new problems, tends to decline with age, while crystallized intelligence, accumulated knowledge such as vocabulary, holds steady or rises into later adulthood. The other options reverse or erase this well-established pattern.
