cognition
|
the mental activities associated with thinking, knowing, remembering and communicating
|
|
concept
|
a mental grouping of similar objects, events, ideas, or people, ie. chair
|
|
category hierarcheis
|
we organize concepts into category hierarchies to simplify things further.
|
|
what are the two ways we form concepts
|
by definition-all three sided geometric forms are triangles
by developing prototypes-a mental image or best example that incorporates all the features we associate with a category. |
|
algorithm
|
a methodical, logical rule or procedure that guarantees solving a particular problem.
|
|
heuristics
|
a simple thinking strategy that often allows us to make judgments and solve problems efficiently, usually speedier but also more error prone than algorithms
|
|
insight
|
sudden flashes of inspiration, sudden comprehension often leads to happy feelings. associated with a burst of activity in the right temporal lobe just above the ear.
|
|
confirmation bias
|
a tendency to search for information that confirms ones preconceptions, test that guess with examples that fit expectations
|
|
fixation
|
inability to see the problem from a fresh perspective, impdement to problem solving
|
|
what are two examples of fixation
|
mental set-predisposes how we think, we tend to approach a problem wiht the mindset of what has worked for us previously
functional fixedness-tendency to only tink of the familiar functions of objects |
|
representativeness heruistic
|
judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead one to ignore other relevant information, such as statistics or logic
|
|
Tversky and Kahneman
|
identified two heuristics of representativeness and availability
|
|
availability heristic
|
estimating the likelihood of events based on their availability in memory; if instances come readily to mind we presume such events are common
|
|
overconfidence
|
the tendency to be more confident than correct - to overestimate the accuracy of one's beliefs and judgments
|
|
what types of things are we likely to fear
|
what our ancestral history has prepared us to fear-yesterdays risks were snakes, lizards and spiders. along with confinement and heights and therefore flying
what we cannot control what is immediate what is most readily available in memory- images of airplane slicing into world trade center form indeleble memories. thousands of safe car trips have extinguished our anxieties about driving |
|
framing
|
the way an issue is posed; how an issue is framed can significantly affect decisions and judgments. Often used in sales and survey questions to support or reject a particular viewpoint
|
|
belief perseverance
|
clinging to ones initial conceptions after the basis on which they were formed ahs been discredited
|
|
language
|
our spoken, written, or signed words and the way we combine them to communicate meaning
|
|
phonemes
|
set of basic sounds, the smallest distinctive sound unit. english has about 40 other languages have half to more than twice that many
|
|
which phonemes carry more info vowels or consenants
|
consonants
|
|
morpheme
|
smallest unit of language that carries meaning in english a few morphemes are also phonemes such as I and a but most are combinations of two or more phonemes.
|
|
grammar
|
a system of rules (semantics and syntax)in a language that enables us to communicate with and understand others
|
|
semantics
|
set of rules we use to derive meaning from morphemes, words and even sentences. ie. adding ed to laugh means it happened in the past. also the study of meaning
|
|
syntax
|
the rules for combining words into grammatically sensible sentences in a given language.adjectives usually come before nouns. enables sentence they are hunting dogs. given context semantics will tell us what they in this sentence is referring to, dogs or people.
|
|
trace course of language acquisition
|
babbling stage- beginning at about 4 months, the stage of speech development in which the infant spontaneously utters various sounds at first unrelated to the household language.
one word stage-from about age 1-2 during which a child speaks mostly in single words two word stage- beginning around age 2 child speaks mostly two word statements telegraphic speech-early speech stage where child speaks like a telegram using mostly nouns and verbs and omitting auxiliary words |
|
in fantis means
|
not speaking
|
|
receptive language
|
ability to comprehend speech
|
|
productive language
|
ability to produce words
|
|
Skinner a behaiviorist believed that babies learned to talk through what method of learning
|
through operant learning, such as assosciation(of the sights of things with the sounds of words), imitation(of the words and syntax modeled by others), and reinforcement(wihg success, smiles and hugs when the child says something right) babies learn to talk in the same ways that animals learn to peck and press bars.
|
|
what happens when there is minimal reinforcement for speaking as is the case with hearing children of deaf parents. their exposure to spoken language is more passive eg. television
|
they learn spoken language more slowly but they learn to sign on a normal time frame
|
|
chomsky said skinners ideas were naive. what did he propose for how we learn language
|
behaivorists oversimplified language acquisition. he says language will naturally occur, given adequate nurture. there is a sort of universal grammar that underlies all human language. brains prewired. if not exposed to language a group of children will over time create their own with gestures, complete with grammar. We come equipped with a sort of witch box-a language acquisiton device-already in place. as we hear language, the switches get set for the language we are to learn.
|
|
surface structure of language
|
chomsky term for we grasp specifc phomenes, morphemes and sentences and the rules by wich we can combine them.
|
|
deep structure of language
|
the meanings of the language.
|
|
how does learning a second language early in life contrast to learning it later in life
|
brain cans reveal that adults who learned a second language early in life use the same patch of frontal lobe tissue. those who learned their second tongue after childhood display activity in a n adjacent brain area wile using their second language
|
|
linguistic determinism
|
whorf's hypothesis that language determines the way we think
|
|
can thinking about doing something make you better at it
|
yes, mental practice has been shown to be effective in many experiments.
|
|
which is more effective outcome simulation or process simulation
|
process simulation
|
|
what is the relation between thinking and language
|
language does influence our thinking but thinking also affects our language.
|
|
do animals think?
|
they form concepts, exhibit insight, use tools, use deception, and transmit cultural innovations. Suddendorf and Whiten(2001) estimate great apes mental accomplishments as very similar to that observed in 2 year old humans.
|
|
Do animals exhibit language?
|
definitely they have comprehension and communication.
but only humans can master the verbal or signed expression of complex rules of syntax |
