25
Telegraphic speech
lacking function morphemes; consists mainly of content words
26
Theory of language acquisition: Behaviourist/Skinner
learning of specific verbal responses through conditioning, imitation
27
Theory of language acquisition: Nativist/Chomsky
- Learning the rules of language - Language Acquisition Device (LAD)
28
Theory of language acquisition: Interactionist explanations
- social interactions and experience on top of innate ability
29
Interactionist Explanations of Language Learning
- View that social experience interacts with innate, biological language abilities (bridges gap btw nativist and enviro approaches) - Parents tailor verbal interactions with their children to simplify language acquisition process (speak slower, clearer, more simply) - no exposure to language = no language
30
Broca's Area
related to aphasia
31
Aphasia
inability or difficulty in producing or comprehending language - Broca's patient could only say "tan" after head trauma - related to left-lower frontal lobe trauma
32
Wernicke's Area
- Patient could produce words, but not sentences - left temporal lobe trauma - responsible for speech comp
33
Important findings from Broca's and Wernicke's Areas
1. there seemed to be an area of the brain controlling speech production 2. there seemed to be an area of the brain controlling speech comprehension 3. language production appeared to be controlled by the left hemisphere
34
Right hemisphere
contributes to language processing and comprehension -with some capacity for processing verbal meaning
35
Bilingualism
- cognitive development slowed in early studies - same language development either way, with different (dis)advantages - learning second language increases ability of left parietal lobe to handle linguistic demands - tends to have later onset of Alzheimer's than monolinguals
36
Linguistic relativity hypotheses
- Sapir-Whorf hypothesis (1897-1941) - Language shapes the nature of thought - research leads us to doubt theory (color perception study)
37
Wharf
was partially correct - language can partly influence thought (when verbal rules help solve problems)
38
concept
mental representation that groups or categorizes shared features of related objects, events, or stimuli
39
necessary condition
something that must be true of the object to belong to the category
40
sufficient condition
something that, if it is true of the object, proves it belongs to the category
41
prototype theory
new objects classified by comparing them to the "best" or "most typical" member of a category
42
exemplar theory
category judgements are made by comparing a new instance with stored memories for some other category cases
43
Prototype
most common, or typical, form a word assumes when we imagine it
44
exemplar
a thing that serves as a goo example of a category member
45
Rational choice theory
decisions made by determining how likely something is to happen, judging the value of the outcome and them multiplying the two - tricky cuz people can estimate frequency but not probability - performance varies with how the problem is described
46
framing effects
people give different answers to the same problem depending on how the problem is phrased
47
prospect theory
people choose to take on risks when evaluating potential losses and avoid risks when evaluating potential gains
48
heuristic
short-cut rules that are applied to solve problems - may not lead to accurate solutions but work to provide quick, efficient solutions when they do work
49
algorithm
well-defined sequence of procedures or rules that guarantees a solution to a problem
50
availability heuristic
we estimate frequencies of events based on how hard it is to think of them - Items more readily available in memory are judged as having occurred more frequently
51
representative heuristic
problem solver mentally compares something to our stored prototype of an event, object, or person - assume something belongs to a category because it seems like the prototype
52
conjunction fallacy
think that two events are more likely to occur together than either as an individual event
53
sunk-cost fallacy
people make decisions about a current situation based on what they have previously invested in the situation
54
confirmation bias
people only pay attention to evidence that supports their original position - ignore disconfirming evidence
55
optimism bias
people believe that, compared with other individuals, they are more likely to experience positive events and less likely to experience negative events in the future
56
belief bias
judgements about whether to accept conclusions depend more on how believable the conclusions are than on whether the arguments are logically valid
57
syllogistic reasoning
determining whether a conclusion follows from two statements that are assumed to be true (belief-laden and neutral trials)
58
means-end analysis
keep the end goal in mind while reaching for means to reduce the differences between the current situation and the desired goal 1. analyze the goal state 2. analyze the current state 3. list the differences between the states 4. reduce the list of differences by - direct means - generating a subgoal - finding a similar problem having a known solution
59
analogical problem solving
find a similar problem with a known solution and applying that solution to the current problem - successful solutions are more likely if participants have faced a similar problem before
60
mental set
expectation of how to solve a problem
61
negative effects of experience
mental set influences how we approach a problem based on expectations - can lead to fixations -- narrows our ability to think of novel solutions
62
functional fixedness
tendency to view an object as only having one function, the one that is commonly used for, and neglecting to see other possible uses
