Thinking/cognition Flashcards
Concepts
Mental groupings of similar objects, events, ideas, or people.
Cognition
The mental activities associated with thinking, knowing, remembering, and communicating.
Prototypes
Mental image or best example of a category
Algorithm
Problem solving method
Heuristics
A simple thinking strategy that often allows us to make judgements and solve problems efficiently; usually speedier but also more error-prone than algorithms.
Insight
A sudden and often novel realization of the solution to a problem. (All of a sudden the answer comes to you)
Confirmation Bias
A tendency to search for information that confirms ones preconceptions.
Fixation
The inability to see a problem from a new perspective; an impediment to problem solving.
Functional fixedness
Inability to solve a problem, because it is viewed only in terms of usual function (activity)
Mental set
A tendency to approach a problem in a particular way, often a way that has been successful in the past
Representativeness heuristic
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. (Example on 401-402
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.
Availability heuristic
Overconfidence
The tendency to be more confident than correct- to overestimate the accuracy of ones beliefs and judgements
Framing
The way an issue is posed; how an issue is framed can significantly affect decisions and judgements.
Belief bias
The tendency for ones preexisting beliefs to distort logical reasoning, sometimes by making invalid conclusions seem valid, or valid conclusions seem invalid.
Belief perseverance
Clinging to ones initial conceptions after the basis on which they were formed has been discredited.
Language
Our spoken, written, or signed words and the ways we combine them to communicate meaning.
Phoneme
In a language, the smallest distinctive sound unit.
Morpheme
In a language, the smallest unit that carries meaning; may be a word or a part of a word (such as prefix)
Grammar
In a language, a system of rules that enables us to communicate with and understand others.
Semantics
The set of rules by which we derive meaning from morphemes, words, and sentences in a given language; also, the study of meaning
Syntax
The rules for combining words, into grammatically sensible sentences in a given language.
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 house hold language
One word stage
The stage in speech development, from about age 1-2 during which a child speaks mostly in single words
Two word stage
Beginning about age 2 the stage in speech development during which a child speaks mostly two words statements
Telegraphic speech
Early speech stage in which a child speaks like a telegram– “go car”- using mostly nouns and verbs and omitting auxiliary words.
Noam Chomsky
Language comes naturally
Linguistic determinism
Whorf’s hypothesis that language determines the way we think
