The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966. [1] [2] [3] It is one of the most famous tasks in the study of deductive reasoning. [4] An example of the puzzle is: You are shown a set of four cards placed on a table, each of which has a number on one side and a color on the other.
A heuristic device is used when an entity X exists to enable understanding of, or knowledge concerning, some other entity Y. A good example is a model that, as it is never identical with what it models, is a heuristic device to enable understanding of what it models. Stories, metaphors, etc., can also be termed heuristic in this sense.
Ariadne's thread, named for the legend of Ariadne, is solving a problem which has multiple apparent ways to proceed—such as a physical maze, a logic puzzle, or an ethical dilemma—through an exhaustive application of logic to all available routes. It is the particular method used that is able to follow completely through to trace steps or ...
Heuristics (from Ancient Greek εὑρίσκω, heurískō, "I find, discover") is the process by which humans use mental shortcuts to arrive at decisions. Heuristics are simple strategies that humans, animals, [1] [2] [3] organizations, [4] and even machines [5] use to quickly form judgments, make decisions, and find solutions to complex problems.
Before Fiske and Taylor's cognitive miser theory, the predominant model of social cognition was the naïve scientist. First proposed in 1958 by Fritz Heider in The Psychology of Interpersonal Relations , this theory holds that humans think and act with dispassionate rationality whilst engaging in detailed and nuanced thought processes for both ...
The heuristic maps onto Rubinstein’s three-step model, according to which people first check dominance and stop if it is present, otherwise they check for dissimilarity. [2] To highlight Rubinstein’s model consider the following choice problem: I: 50% chance to win 2,000. 50% chance to win nothing. II: 52% chance to win 1,000. 48% chance to ...
Motivated reasoning (motivational reasoning bias) is a cognitive and social response in which individuals, consciously or sub-consciously, allow emotion-loaded motivational biases to affect how new information is perceived. Individuals tend to favor evidence that coincides with their current beliefs and reject new information that contradicts ...
In insight problems this usually occurs late in the puzzle. The second way that people attempt to solve these puzzles is the representational change theory. [14] The problem solver initially has a low probability for success because they use inappropriate knowledge as they set unnecessary constraints on the problem.
