Q

availability heuristic

A

drawing on personal experience or readily accessible examples that come to mind when trying to assess probability
often leads to the wrong conclusion because decision making can be skewed by recently learned information

25
biases
overconfidence bias belief perseverance confirmation bias framing
26
overconfidence bias
tendency to overestimate one's own capability or correctness
27
fluency
ease of processing that can contribute to overconfidence in the material
28
belief perseverance
ignoring or rationalizing information that disproves one's beliefs in order to maintain those beliefs
29
confirmation bias
tendency to seek out and favor information that supports existing beliefs
30
framing
manner in which information is presented is often capable of skewing decision making based on that information
31
initelligence
mental quality that describes the ability to acquire and use new information, solve problems and learn from experience
32
IQ
intelligence quotient | measure of intelligence based on a test that divides the test-taker's mental age by their physical age
33
theory of general intelligence
idea that there is one universal type of mental ability that allows for success in all fields each individual has different levels of this one general ability
34
G-Factor
the quantitative measure used in the theory of general intelligence
35
Sternberg's Triarchic Theory of Intelligence
there are 3 distinct categories of mental abilities that contribute to real world success: analytical, creative, and practical abilities
36
analytical intelligence
category of mental abilities that allows for effective problem solving and learning, and can be measured with an IQ test
37
creative intelligence
helps a person deal with novel situation by drawing on past experience and generate new ideas
38
practical intelligence
allows a person to adapt to their environment and to deal with ill-defined problems
39
emotional intelligence
ability to deal with emotionally charged problems or situations includes being aware of and controlling one's own personal emotions and how they are expressed, and handling interpersonal conflicts and emotional situations successfully
40
fluid intelligence
mental ability that allows a person to solve novel problems, reason through problems, and think abstractly and logically this tends to decrease with age
41
crystallized intelligence
the accumulation of knowledge through experience and the ability to apply this knowledge tends to increase with age
42
heritability
proportion of a trait or quality that is due to genes | often studied through twin studies to control for genetic and/or environmental differences
43
fixed mindset
belief that the amount of intelligence a person possesses cannot be changed over time or with practice and experience, and is biologically based
44
growth mindset
belief that the amount of intelligence a person possesses can be changed through experience and learning, rather than being biologically set
45
theory of primary mental abilities
there are 7 distinct categories of intelligence: verbal comprehension, reasoning, perceptual speed, numerical ability, spatial visualization, associative memory, word fluency
46
theory of multiple intelligences
Howard Gardner's idea that there are 7 independent mental abilities that encompass much more than what can be tested with an IQ test 7 abilties - visual-spatial, verbal-linguistic, bodily-kinesthetic, logical-mathematical, interpersonal, musical, intrapersonal, and naturalistic intelligence
47
cognitive dissonance
experience of discomfort due to one's conflicting and concurrently-held beliefs, or actions that conflict with one's held beliefs
48
language
systematic method of communication which can be verbal or non-verbal and has some standard and formalized rules
49
aphasia
any condition that affects language abilities
50
Broca's area
part of the frontal lobe (typically in the left hemisphere) that is responsible for the production of speech
51
Broca's (non-fluent) aphasia
condition characterized by an inability to produce speech reliably, despite being able to comprehend speech often caused by damage to the left frontal lobe
52
Wernicke's area
posterior part of the temporal lobe (typically in the left hemisphere) that is responsible for the comprehension of speech
53
Wernicke's (fluent) aphasia
condition characterized by the inability to comprehend speech while still being able to produce nonsense speech due to damage in the posterior portion of the left temporal lobe
54
global aphasia
inability to comprehend or produce speech | typically caused by damage to both Wernicke's and Broca's area
55
arcuate fasciculus
group of nerve fibers that connect Broca's area to Wernicke's area
56
conduction aphasia
speech impairment condition characterized by the inability to repeat things, despite full comprehension and ability to produce speech typically caused by damage to the arcuate fasciculus
57
agraphia
type of aphasia characterized by an inability to write
58
anomia
type of aphasia characterized by an inability to name objects
59
split brain patients
people who have had their corpus callosum surgically cut, usually to treat seizures results in impaired communication between the two hemispheres, including an inability to name objects presented to only the left visual field
60
contralateral organization
sensations that are stimulated on one side of the body are processed in the hemisphere opposite
61
linguistic universalism
thought precedes language, and language only exists to describe these thoughts
62
linguistic determinism
language determines and limits though
63
strong linguistic determinism (whorfian hypothesis)
theory that language completely controls and limits thought by giving it structure
64
weak linguistic determinism
theory that language influences, but does not completely determine, thought patterns through the way thought is structured
65
nativist theory of language development
Noam Chomsky's idea that the ability to learn language is innate and stored in the language acquisition device in the brain based on the idea that all languages share universal grammar that children are naturally able to pick up on, and these skills have a critical period after which they deteriorate
66
universal grammar
underlying principles or template that govern all languages and are innate to humans makes language easy to learn during the critical period
67
critical period
time in a child's life when they are the most capable of learning a language usually lasts from birth to age 8 or 9
68
language acquisition device
hypothetical part of the brain that (according to Chomsky) stores the basis of universal grammar and is responsible for learning language Chomsky thought this was only active from birth to age 8
69
learning theory of language acquisition
idea supported by Skinner and other behaviorists that children acquire language through reinforcement theory fails to account for the fact that children can produce words or sentences they have never heard
70
social interactionist approach to language development
humans are innately capable of learning language and choose to do so because of social factors and the desire to interact with others
