UNIT 5 Solving Problems and Making Decisions
Term | Definition |
---|---|
algorithm | a methodical, logical rule or procedure that guarantees solving a particular problem. Contrasts with the usually speedier-but also more error-prone-use of heuristics. |
heuristics | a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than an algorithm. |
insight | a sudden realization of a problem's solution; contrasts with strategy-based solutions. |
confirmation bias | a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence. |
fixation | in cognition, the inability to see a problem from a new perspective; an obstacle to problem solving. |
mental set | a tendency to approach a problem in one particular way, often a way that has been successful in the past. |
intuition | an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning. |
representativeness heuristic | estimating the likelihood of events in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information. |
availability heuristic | 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. |
overconfidence | the tendency to be more confident than correct-to overestimate the accuracy of our beliefs and judgments. |
belief perseverance | clinging to one's initial conceptions after the basis on which they were formed has been discredited. |
framing | the way an issue is posed; how an issue is worded can significantly affect decisions and judgments. |
