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.
The Wason selection task provides evidence for the matching bias. [15] The test is designed as a measure of a person's logical thinking ability. [50] Performance on the Wason Selection Task is sensitive to the content and context with which it is presented. If you introduce a negative component into the conditional statement of the Wason ...
Congruence bias is the tendency of people to over-rely on testing their initial hypothesis (the most congruent one) while neglecting to test alternative hypotheses. That is, people rarely try experiments that could disprove their initial belief, but rather try to repeat their initial results. It is a special case of the confirmation bias.
This requires a different selection answer, as the 8, brown, and red cards must be turned over to guarantee equivalence. It is an implication in the article text: "if a card shows an even number on one face, then its opposite face shows a primary colour" The subtlety of implication is much of the point of the Wason selection task.
Deductive reasoning. Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and " Socrates is a man" to ...
Confirmation bias, a phrase coined by English psychologist Peter Wason, is the tendency of people to favor information that confirms or strengthens their beliefs or values and is difficult to dislodge once affirmed. [4] Confirmation biases are effects in information processing.
Jonathan St B. T. Evans (born 30 June 1948) [2] is a British cognitive psychologist, currently Emeritus Professor of Psychology at the University of Plymouth. [3] In 1975, with Peter Wason, Evans proposed one of the first dual-process theories of reasoning, an idea later developed and popularized by Daniel Kahneman.
Hawk-dove. An evolutionarily stable strategy (ESS) is a strategy (or set of strategies) that is impermeable when adopted by a population in adaptation to a specific environment, that is to say it cannot be displaced by an alternative strategy (or set of strategies) which may be novel or initially rare.
