Journal ArticleDOI
On the conflict between logic and belief in syllogistic reasoning.
TL;DR: A conflict between logic and belief is observed throughout, but at several levels of extent; even subjects who focus primarily on the conclusion are influenced to an extent by the logic.
Journal ArticleDOI
Dual processes in reasoning
P. C. Wason,J. St B. T. Evans +1 more
TL;DR: In this article, the introduction of negatives into the sentences used in a deductive problem affected behavior in a systematic way which was independent of the logical structure of the problem, and the subjects were asked to justify their responses when reasoning about such sentences.
Journal ArticleDOI
Facilitation of reasoning by realism: Effect or non‐effect?
TL;DR: In this article, a series of five experiments was performed comparing abstract and thematic materials in Wason's (1966) selection task, and none of the experiments showed any facilitation of performance on thematic rules.
Journal ArticleDOI
Matching bias in the selection task.
J. St B. T. Evans,J. S. Lynch +1 more
TL;DR: This paper found that subjects tend to match rather than alter named values when constructing verifying and falsifying cases of conditional rules and that this tendency might explain the responses normally observed in Wason's (1968, 1969) selection task.
Journal ArticleDOI
