Peter Wason was the grandson of Eugene Wason, [2] and the son of Eugene Monier and Kathleen (Woodhouse) Wason. [3] Wason married Marjorie Vera Salberg in 1951, and the couple had two children, Armorer and Sarah. [3] His uncle was Lieutenant General Sydney Rigby Wason. Peter Wason endured his schooling, which was marked by consistent failure. [2]
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 THOG problem is one of cognitive psychologist Peter Wason's logic puzzles, constructed to show some of the weaknesses in human thinking. You are shown four symbols a black square; a white square; a black circle; a white circle; and told by the experimenter "I have picked one colour (black or white) and one shape (square or circle).
In Peter Wason's initial experiment published in 1960 (which does not mention the term "confirmation bias"), he repeatedly challenged participants to identify a rule applying to triples of numbers. They were told that (2,4,6) fits the rule. They generated triples, and the experimenter told them whether each triple conformed to the rule. [3]: 179
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.
Peter Wason and Jonathan St B. T. Evans suggested dual process theory in 1974. [4] In Evans' later theory, there are two distinct types of processes: heuristic processes and analytic processes. He suggested that during heuristic processes, an individual chooses which information is relevant to the current situation.
The ease with which people make conditional inferences is affected by context, as demonstrated in the well-known selection task developed by Peter Wason. Participants are better able to test a conditional in an ecologically relevant context , e.g., if the envelope is sealed then it must have a 50 cent stamp on it compared to one that contains ...
