Q

prototype theory of classifications

A

objects are put into concepts by comparing them to the prototype (rather than seeing if it fits the rules)

Q

heuristic

A

general rule-of-thumb strategy that only might work, lowers the number of possible solutions (eg break a problem into subgoals, or work backwards from a goal)

Q

2 stage model of intuition

A

intuition includes the guiding stage (unconscious perception of a pattern of information) and an integrative stage (the representation of the pattern become conscious)

Q

functional fixedness

A

interferes with problem-solving, only view objects as functioning in the usual way, prevents seeing full range of objects use

Q

additive model

A

generate a list of important factors, then rate each alternative on an arbitrary scale, add up scores- highest is the winner

23
Q

availability heuristic

A

estimate the likelihood of an event based on other instances of the event in memory

24
Q

representativeness heuristic

A

estimate events likelihood by comparing how similar it its essential features are to that events prototype

25
language
system for combining arbitrary symbols to produce meaningful statements
26
belief-bias effect
obstacle to logical thinking, people only accept evidence that conforms to their beliefs
27
confirmation-bias effect
obstacle to logical thinking, search for information that confirms a belief
28
fallacy of positive instances
obstacle to logical thinking, the tendency to remember uncommon events (coincidences) that confirm beliefs
29
overestimation effect
obstacle to logical thinking, overestimation of the rarity of an event
30
symbols
sounds, written words, formalized gestures (ASL) required for language, meaning is shared by others who speak the same language
31
syntax
set or rules for combining words, unaware of rules but its clear when their violated
32
generative
an infinite number of new phrases can be generated
33
displacement
can communicate meaningfully about ideas/objects not physically present
34
whortan hypothesis
linguistic relativity hypothesis, differences among languages cause different thought processes
35
bilingualism
fluency in 2 or more languages, cognitive benefits (eg attention control, taking perspectives of others in social situations)
36
animal cognition
comparative cognition, study aspects of animal behavior (eg can acquire some language aspects)
37
intelligence
capacity to think rationally, act purposefully, and deal effectively with the environment
38
Alfred Binet
test for French government focused on elementary mental abilities (eg memory and attention) that you didn't learn in school
39
mental age
mental level differs from a childs chronological age
40
Lewis Terman
Standford-Binet Intelligence Test: intelligence quotient (IQ), mental age/chronological age * 100, spread by the army alpha (written) and beta (oral) tests
41
David Wechsler
Wechsler Adult Intelligence Scale (WAIS), combined scores of performance score (nonverbal subjects) and verbal score, believe intelligence involved many mental abilities
42
achievement tests
measure knowledge in a particular area
43
aptitude test
assess capacity to benefit from education, predict ability to learn certain types of information
44
3 requirements of a scientifically acceptable test
standardization, reliability, validity
45
standardization
tests are given to a large number of subjects of a particular group, the scores of the group determine the standards/norm (usually normal curve)
46
reliability
consistently produces similar scores on different occasions
47
validity
test measures what its supposed to
48
Charles Spearman
general mental capacity is the core of many different mental abilities, g factor
49
general intelligence (g factor)
responsible for overall performance on tests of mental ability, intelligence is a single measure of general cognitive ability, therefore IQ is accurate
50
Louis L. Thurstone
intelligence is 7 primary mental abilities, the g factor is the overall average of the 7 and is less important
51
Howard Gardner
different mental abilities biologically distinct and controlled by different brain regions, (like Thurstone) mental abilities independent of each other, therefore can't be measured as 1 intelligence, an intelligence is the ability to solve problems or create products
52
Robert Sternberg
intelligence is a broad quality, triarchic theory of intelligence
53
triarchic theory of intelligence
successful intelligence involves analytic (learn to solve problems, creative (deal with new situation by drawing existing skills), and practical (adapt to environment) intelligence
54
heritability
percent variation in a population due to heredity, accepted heritability estimate is 50% (50% of differences in IQ scores are due to genetics)
55
Flynn Effect
the general improvement in average IQ scores in different cultures/countries, showed importance of environment on IQ
56
Claude Steele's stereotype threat
members of a group that are aware of a negative stereotype about their group will fear they will be judged in terms of that stereotype or confirm that stereotype
57
stereotype lift
awareness of positive expectations can improve task performance
