Chapter 6 Flashcards
computer metaphor
the idea that the brain is an information processing system like a computer
concepts
mental groupings of similar objects, ideas, or experiences
natural concepts
mental representations of objects and events drawn from our own experiences
prototype
an ideal or most representative example of a conceptual category
artificial concepts
concepts defined by rules, such as word definitions and mathematical formulas
concept hierarchies
levels of concepts, from the most general to the most specific, in which a more general level includes more specific concepts…the concept of animal includes dog, giraffe, and butterfly
intuition
the ability to make judgments without consciously reasoning
script
a cluster of knowledge about sequences of events and actions expected to occur in a particular setting
algorithms
problem-solving procedures and formulas that guarantee a correct outcome, if properly applied
heuristics
cognitive strategies or “rules of thumb” used as shortcuts to solve problems, these are not guaranteed
mental set
the tendency to respond to a new problem in a manner used for a previous problem
functional fixedness
the inability to perceive a new use for an object associated with a different purpose
hindsight bias
the tendency, after learning about an event, to “second guess” or believe that one could have predicted the event in advance
anchoring bias
a faulty heuristic caused by basing an estimate on a completely irrelevant quality
representativeness bias
a faulty heuristic strategy based on the assumption that, once people or events are categorized, that they all share the same features as other members of that category
base rate information
the probability of a characteristic appearing in the general population
availability bias
a faulty heuristic strategy that eliminates probabilities based on the availability of vivid mental images of an event
