A

an increase in a cell’s firing potential after brief, rapid stimulation; a neural basis for learning and memory.

31
Q

priming

A

the activation, often unconsciously, of particular associations in memory.

32
Q

encoding specificity principle

A

the idea that cues and contexts specific to a particular memory will be most effective in helping us recall it.

33
Q

mood-congruent memory

A

the tendency to recall experiences that are consistent with one’s current good or bad mood.

34
Q

serial position effect

A

our tendency to recall best the last (recency effect) and first (primacy effect) items in a list.

35
Q

anterograde amnesia

A

an inability to form new memories.

36
Q

retrograde amnesia

A

an inability to retrieve information from one’s past.

37
Q

proactive interference

A

the forward-acting disruptive effect of older learning on the recall of new information.

38
Q

retroactive interference

A

the backward-acting disruptive effect of newer learning on the recall of old information.

39
Q

repression

A

in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories.

40
Q

reconsolidation

A

a process in which previously stored memories, when retrieved, are potentially altered before being stored again.

41
Q

misinformation effect

A

occurs when misleading information has distorted one’s memory of an event.

42
Q

source amnesia

A

faulty memory for how, when, or where information was learned or imagined. (Also called source misattribution.) Source amnesia, along with the misinformation effect, is at the heart of many false memories.

43
Q

deja vu

A

that eerie sense that “I’ve experienced this before.” Cues from the current situation may unconsciously trigger retrieval of an earlier experience.

44
Q

cognition

A

all the mental activities associated with thinking, knowing, remembering, and communicating.

45
Q

concept

A

a mental grouping of similar objects, events, ideas, or people.

46
Q

prototype

A

a mental image or best example of a category. Matching new items to a prototype provides a quick and easy method for sorting items into categories (as when comparing feathered creatures to a prototypical bird, such as a robin).

47
Q

creativity

A

the ability to produce new and valuable ideas.

48
Q

convergent thinking

A

narrowing the available problem solutions to determine the single best solution.

49
Q

divergent thinking

A

expanding the number of possible problem solutions; creative thinking that diverges in different directions.

50
Q

algorithm

A

a methodical, logical rule or procedure that guarantees solving a particular problem. Contrasts with the usually speedier— but also more error-prone— use of heuristics.

51
Q

heuristic

A

a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than an algorithm.

52
Q

insight

A

a sudden realization of a problem’s solution; contrasts with strategy-based solutions.

53
Q

confirmation bias

A

a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence.

54
Q

fixation

A

in cognition, the inability to see a problem from a new perspective; an obstacle to problem solving.

55
Q

mental set

A

a tendency to approach a problem in one particular way, often a way that has been successful in the past.

56
Q

intuition

A

an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning.

57
Q

representativeness heuristic

A

estimating the likelihood of events in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information.

58
Q

availability heuristic

A

estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common.

59
Q

overconfidence

A

the tendency to be more confident than correct— to overestimate the accuracy of our beliefs and judgments.

60
Q

belief perseverance

A

clinging to one’s initial conceptions after the basis on which they were formed has been discredited.

61
Q

framing

A

the way an issue is posed; how an issue is worded can significantly affect decisions and judgments.

62
Q

language

A

our spoken, written, or signed words and the ways we combine them to communicate meaning.

63
Q

phonemes

A

in a language, the smallest distinctive sound unit.

64
Q

morphemes

A

in a language, the smallest unit that carries meaning; may be a word or a part of a word (such as a prefix).

65
Q

grammar

A

in a language, a system of rules that enables us to communicate with and understand others. Semantics is the language’s set of rules for deriving meaning from sounds, and syntax is its set of rules for combining words into grammatically sensible sentences.

66
Q

babbling stage

A

beginning around 4 months, the stage of speech development in which an infant spontaneously utters various sounds at first unrelated to the household language.

67
Q

one-word stage

A

the stage in speech development, from about age 1 to 2, during which a child speaks mostly in single words.

68
Q

two-word stage

A

beginning about age 2, the stage in speech development during which a child speaks mostly in two-word statements.

69
Q

telegraphic speech

A

early speech stage in which a child speaks like a telegram—“ go car”— using mostly nouns and verbs.

70
Q

aphasia

A

impairment of language, usually caused by left hemisphere damage either to Broca’s area (impairing speaking) or to Wernicke’s area (impairing understanding).

71
Q

Broca’s area

A

helps control language expression— an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech.

72
Q

Wernicke’s area

A

a brain area involved in language comprehension and expression; usually in the left temporal lobe.

73
Q

linguistic determinism

A

the strong form of Whorf’s hypothesis— that language controls the way we think and interpret the world around us.

74
Q

linguistic influence

A

the weaker form of “linguistic relativity”— the idea that language affects thought (thus our thinking and world view is “relative to” our cultural language).
