What is the Wason four card problem?
The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966. It is one of the most famous tasks in the study of deductive reasoning.
What does the Wason selection task prove?
One of the longest-running debates in modern psychology centers on the correct interpretation of the Wason Selection Task. Peter Wason originally designed the test to see if people applied logic that would disprove a hypothesis by falsifying it as well as by confirming it.
What is Wason’s card?
a reasoning task involving four cards, each with a letter on one side and a number on the other, and a rule supposedly governing their correlation (e.g., if the letter is a vowel, then the number is even).
When was the Wason abstract?
When the “abstract” version of the Wason four-card problem is compared to a “concrete” version of the problem (in which beer, soda, and ages are substituted for the letters and numbers), performance is better for the concrete task.
What are subjects asked in a typical Wason selection task?
The Wason selection test therefore evaluates subjects’ ability to find facts that violate a hypothesis, specifically a conditional hypothesis of the form If P then Q. In Wason’s test, four “facts” are presented in the form of cards.
Who Discovered confirmation bias?
Peter Wason
The phenomenon was first described as confirmation bias by Peter Wason in 1960. In what’s known as Wason’s Rule Discovery Test, he conducted an experiment in which participants were asked to find a rule that applied to a series of three numbers.
When the abstract version of the Wason four card problem is compared?
What is permission schema?
According to Cheng and Holyoak, this is due to the fact that the permission schema is defined by a set of production rules that give the same answers to problems of conditional inference as those of formal logic. In order to test this hypothesis specifically, 160 university students were given one of two tests.
