a mental image or best example of a category. This provides a quick and easy way to categorize new stimuli
a methodical, logical rule or procedure that guarantees solving a particular problem. Not as fast as the use of heuristics, but more accurate
a simple thinking strategy that often allows us to make judgments and solve problems efficiently
a sudden and often novel realization of the solution to a problem; it contrasts with strategy-based solutions
a tendency 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
a tendency to think of only the familiar functions for objects, without imagining alternative uses
judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes. This may lead to ignorance of other relative 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 one's initial conceptions after the basis on which they were formed has been discredited
an effortless, immediate, automatic feeling or though, as contrasted with explicit, conscious reasoning

early speech stage in which a child speaks like a telegram ("go car") using mostly nouns and verbs
Skinner and Operant learning
the theory that language development comes from association (the sights of things with the sounds of words), imitation (of the words and syntax modeled by others), and reinforcement (smiles and hugs from parents when something is said correctly
Chomsky and inborn universal grammar
the theory that, given adequate nurture, language will occur naturally. This theory comes from the fact that children learn untaught words and grammar at an incredibly fast rate and they generate sentences they've never heard, some with errors like adding -ed to make things past tense
impairment of language, usually caused by left hemisphere damage to either Broca's area (speaking) or to Wernicke's area (understanding)
an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movement involved in speech
an area usually in the left temporal lobe that is involved in language comprehension and expression
