Cognition in AP Psychology: How We Think, Solve Problems, and Use Language

Concept

A mental grouping of similar objects, events, or people that helps organize information and speed up thinking.

Prototype

A mental “best example” of a category that you compare new items to when classifying them (can bias judgments toward what seems typical).

Creativity

The ability to produce ideas that are both novel (original) and useful (effective/appropriate).

Convergent Thinking

Thinking style that narrows options to find a single best solution; useful for accuracy (e.g., many multiple-choice problems).

Divergent Thinking

Thinking style that expands options by generating many possible solutions; useful for originality (e.g., brainstorming).

Problem Solving

The cognitive process of working toward a goal when the solution is not immediately obvious, often involving representing the problem, testing strategies, and revising.

Algorithm

A step-by-step procedure that guarantees a correct solution if applied correctly, but may be slow and mentally costly.

Heuristic

A simple, efficient rule-of-thumb strategy that often helps solve problems but does not guarantee a correct answer and can produce errors.

Insight

A sudden realization of a problem’s solution (“aha” moment), often resulting from restructuring how the problem is represented.

Mental Set

A tendency to approach a problem using a method that worked in the past, even when a different strategy is needed.

Functional Fixedness

A type of fixation where you see objects only in terms of their typical functions, making it harder to use them in novel ways.

Dual Processing

The idea that thinking operates in two modes: a fast, automatic, intuitive mode and a slower, deliberate, analytical mode.

Availability Heuristic

Judging the likelihood of an event based on how easily examples come to mind (often influenced by vividness or media coverage rather than statistics).

Representativeness Heuristic

Judging the probability that something belongs to a category based on how closely it matches a prototype, sometimes leading people to ignore base rates.

Anchoring Effect

When an initial piece of information (often a number) strongly influences later judgments because people don’t adjust far enough away from the “anchor.”

Confirmation Bias

The tendency to seek or interpret information in ways that support existing beliefs while downplaying or ignoring contradictory evidence.

Framing

A decision-making effect where the way an issue is posed (e.g., “90% survival” vs. “10% mortality”) changes judgments and choices.

Wernicke’s Area

A brain region associated with language comprehension; damage can cause fluent but nonsensical speech and impaired understanding (Wernicke’s aphasia).

Broca’s Area

A brain region associated with language production; damage can cause slow, effortful speech with reduced grammar (Broca’s aphasia).

Phoneme

The smallest distinctive sound unit in a language (sounds are language-specific).

Morpheme

The smallest unit that carries meaning (e.g., “cat,” “un-,” “-ed,” “-s”).

Syntax

Rules for arranging words into grammatically correct sentences (sentence structure).

Semantics

Rules for deriving meaning from words and sentences; word order can change meaning (e.g., “dog bit man” vs. “man bit dog”).

Telegraphic Speech

Early speech stage where children use mostly nouns and verbs and omit smaller function words (e.g., “Doggie go park”).

Critical Period (Language Acquisition)

A time window (especially early childhood) when language is most easily learned to native-like levels; later learning is typically harder, not impossible.
