 | Term | Definition |
| |
Cognition |
process whereby we acquire and use knowledge; key elements: reviewing the past, contemplating the future, thinking about possibility; thinking |
| |
language |
a flexible system of communication using sounds, rules, gestures, or symbols to convey information; is semantic (meaningful)-gives detailed information; displacement-allows communication over time; productive-create new words to communicate |
| |
phonemes |
basic sound units; indicates change in meaning; universal; 45 phonemes in English, up to 85 in other languages; string together to create morphemes; examples:/s/, /z/, /ch/, /th/, /k/, etc. |
| |
morphemes |
smallest meaningful units of speech; simple words, suffixes, prefixes; examples: red, hot, calm, -ed, pre- |
| |
surface structure |
the particular words and phrases used to make up a sentence |
| |
deep structure |
the underlying meaning of a sentence |
| |
grammar |
language rules; determines how sounds and words can be combined; used to communicate meaning within a language; has two components: syntax and semantics; meaning is often determined by word order; Noam Chomsky; allows people to make transformation from surface to deep structure in sentences |
| |
semantics |
criteria for assigning meaning to the morphemes in a language; influenced by Noam Chomsky; content of language; evidence by surface and deep structure |
| |
syntax |
Noam Chomsky; system of rules that governs how words are combined/arranged to form meaningful phrases and sentences; determined by word order |
| |
image |
nonverbal; visual, auditory, olfactory; mental representations; Einstein felt that scale in visualizing abstract concepts lead to insights; can be manipulated mentally (Shepard and Metzler) geometric patterns |
| |
concept |
mental categories; classifying objects, people, or experiences; can be modified to better manage experience; example-dogs, books, cars<-- objects in world; fast, strong, interesting<-- things, people, events |
| |
information retrieval |
the idea that language affects our ability to store and retrieve information as well as our ability to think about things; evidence by linguistic determinism; pulled info from long-term memory |
| |
prototype |
Rosch; mental model; model that contains the most typical features of concept; example: cat-pale, whiskers, meow, clause, for, ears |
| |
Idealized Cognitive Model (ICM) |
Rosch; expands on prototypes; concept + schema; example: mother |
| |
problem representation |
first step in problem-solving; interpreting or defining a problem |
| |
trial and error |
problem-solving strategy; best if there are limited choices; takes time to try all approaches; try one approach, fail; and another until you succeed; guarantees a solution |
| |
algorithm |
problem-solving strategy; step by step method that guarantees a solution; must be appropriate for the problem to be use; math is a good example |
| |
heuristic |
problem-solving strategy; rule of Tom; does not guarantee a solution; simplifies a problem so a solution may be found; four types: hillclimbing, subgoals, means-end analysis, and working backward |
| |
hillclimbing |
a heuristic; each set move to progressively closer to a final goal; simple; example: balancing a budget, reduce expenses to a smaller deficit |
| |
subgoals |
a heuristic; break problem into smaller, more manageable pieces; example: Hobbits and Orcs problem |
| |
means-end analysis |
a heuristic; probably most use; combines hillclimbing and subgoals; analyze a difference between the current situation and the desired outcome, then do something to reduce the difference; does not preprint detours from final goal; example: pitcher's strategy with best batter-ultimate goal-to win game and keep batters off the base, a walk the best batter to eliminate more runs |
| |
working backward |
a heuristic; used when means end analysis strays from goal; begin with goal and work backwards towards the "givens"; used when goal has more information than the givens and when the operations involved work two ways; example: $100 to spend, buy one item and subtract $100 to determine how much is left |
| |
set |
mental set; tendency to perceive and approach problems in certain ways; determines what information we retrieved from memory to help us find a solution (includes heuristics and algorithms); flexibility comes from multiple sites to choose from (switch or abandon sets); pandered by function fixedness |
| |
functional fixedness |
a hindrance to problem-solving; "assigning" an object in one function (which is how we form concepts); seeing a limited number of uses for an object; example: what can use a pencil for? A brick? |
| |
Tactic of elimination |
problem-solving strategy; less all possible solutions then discard all solutions that seem to lead in the wrong direction |
| |
visualizing |
basic building blocks of thought; diagramming a course of action |
| |
divergent thinking |
thinking outside the box; generating as many unique answers as possible |
| |
convergent thinking |
only one answer; answers are narrow in focus; example: math problems |
| |
compensatory model |
a rational decision making model; choices are rated on various criteria (attractive criteria offset or compensate for unattractive features); example: buying a car-1. Higher price, better gas mileage 2. Lower price, lower mpg which do you buy ? |
| |
noncompensatory model |
decision making model; where criteria is not so rational; example: car buying-hinges on car color |
| |
representativeness |
heuristic; decision making model; new situation judged on its resemblance to a stereotypical model; example: you buy an expensive clothes and they fall apart, he judged anything inexpensive to be cheap therefore it is representative of the quality |
| |
availability |
decision-making heuristic; judgment or decision is based on information that is most easily retrieved; type of: Subway Effect-law of nature that you are situation seldom occurs and we adjust accordingly (the other line his faster, until you give in it) |
| |
confirmation bias |
decision-making heuristic; tendency to look for evidence in support of a believe and to ignore evidence to disprove the believe; seeing patterns of cause and effect when there is any pattern; example: AIDS, chocolate and acne |
| |
linguistic-relativity hypothesis |
Benjamin Whorf; thinking patterns based on specific languages; evidence by linguistic determinism |
| |
figurative language |
expressive language; smiles and metaphors |
| |
telegraphic speech |
early speech; stage of one and two-year-olds that omits nonessential words; often used by primates; example: more milk! |
| |
Framing |
perspective or phrasing of information used to make a decision; studies on survival and mortality framing |
| |
hindsight bias |
tendency to view outcomes as inevitable and predictable after we know the outcome, and believe that we could have predicted what happened; "I knew it all along" |
| |
linguistic determinism |
idea of the patterns of thinking are determined by the specific language one speaks; Benjamin more; example: Hopi language as to nouns for "flies"-one for birds and one for everything else; Dani limited color terminology-light/dark |
| |
counterfactual thinking |
thinking about alternative realities and things that never happened; what ifs |
