all the mental activities associated with thinking, knowing, remembering, and communicating
a mental image or best example of a category. provides a quick and easy method for sorting items into categories
a methodical, logical rule of procedure that guarantees solving a particular problem; contrast with the usual speedier --but also more error prone - use of heuristics
a simple thinking strategy that often allows us to make judgments and solve problems efficiently: usually speedier but more error prone than algorithms ("rule of thumb")
a sudden, often novel realization of a solution to a problem; it contrasts with a strategy-based solution
a tendancy to search for information that supports our preconceptions and to ignore or distort contradictory evidence
a tendency to approach a problem in one particular way, often a way that has been successful in the past
the tendency to think of things only in terms of their usual function; the impediment to problem-solving
judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information
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
the tendency to be more confident than correct - to overestimate the accuracy of our beliefs and judgments
clinging to ones initial conceptions after the basis on which they were formed has been discredited
the way an issue is posed; how an issue is framed can significantly affect decisions and judgments
in a language, the smallest unit that carries meaning; may be a word, or part of a word (such as a prefix)
the set of rules by which we derive meaning from morphemes, words, and sentences in a given language; also, the study of meaning
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
the stage in speech development, from about age 1-2, during which a child speaks mostly in single words
beginning at about age 2, the stage in speech development during which a child speaks mostly two word statements
impairment of language, usually caused by left hemisphere damage, either to Broca's area (impairing speech) or to Wernicke's area (impairing understanding)
controls language experssion - an area of the frontal lobe, usually in left hemisphere, that directs the muscle movements involved in speech
controls language reception - a brain area involved in language comprehension and expression; usually in the left temporal lobe
A mental representation that has some of the physical characteristics of an object; it is analogous to the object.
the tendency for one's preexisting beliefs to distort logical reasoning, sometimes by making invalid conclusions seem valid, or valid conclusions seem invalid
"father of language research" - humans have a universal grammar device that predisposes us to learn language. [deep structure = true meaning, surface structure = grammar of learned language]
The theory that we act to reduce the discomfort we feel when two of our thoughts are inconsistent. For example, when our awareness of our attitudes and our actions clash, we can reduce the resulting dissonance by changing our attitudes.
times during which certain environmental influences can have an impact on the development of the infant
reasoning in which a conclusion is reached by stating a general principle and then applying that principle to a specific case (The sun rises every morning; therefore, the sun will rise on Tuesday morning.)
defining attribute model
The idea that a concept is characterized by a list of features that are necessary to determine if an object is a member of the category.
deriving general principles from particular facts or instances ("Every cat I have ever seen has four legs; cats are four-legged animals").
The worldview of a culture is shaped and reflected by the language its members speak.
the apprehension experienced by members of a group that their behavior might confirm a cultural stereotype
