Two experiments were conducted to show that the IF … THEN … rules used in the different versions of Wason's (1966) selection task are not psychologically—though they are logically—equivalent. Some of these rules are considered by the participants as strict logical conditionals, whereas others are interpreted as expressing a biconditional relationship. A deductive task was used jointly with the selection task to show that the original abstract rule is quite ambiguous in this respect, contrary to… 

Selection Task with Conditional and Biconditional Sentences: Interpretation and Pattern of Answer

The results showed that the responses to the selection task widely depended on the sentence interpretation and that conditional and biconditional sentences were interpreted, at least in part, in analogous way.

Evolutionary Psychology and Human Reasoning: Testing the Domain-Specificity Hypothesis through Wason Selection Task

A between-subjects study with 640 participants showed that the better performance in the selection task with deontic rules is independent of the content of the rule and is associated to the "reasoning from" task.

Testing Massive Modularity Hypothesis through the Selection Task: Content of Rules, Forms of Reasoning, or Pragmatic Expectations? Formal, Content, and Pragmatic Aspects in Human Reasoning

"reasoning from" tasks were better performed than "reasoning about" tasks, regardless of the content of the rule and the type of expectation, and the putative effect of pragmatic expectation on the participants' performance was examined.

Putting Context Dependent Human Logical Reasoning into the Right Context

The approach presented in this paper is in conflict with an interdisciplinary field that has developed over the course of more than a hundred years, and represents a fight that is reminiscent of David and Goliath.

Learning Logic: examining the effects of context ordering on reasoning about conditionals

The results suggest that context ordering influences learners’ reasoning and the importance of sequencing for learning to reason about conditionals, and propose the symbolic–intuitive–abstract–counter intuitive–symbolic ordering.

Massive modularity? The relationship between context-relevance, information encapsulation and functional specialization

In this article, I discuss the debate between domain-specificity and content-generality in regard to the human mind. My main objective is to argue that the human mind can both be understood as a

Les canons de la rationalité: essai de classification des points de vue dans le débat sur les biais cognitifs et la rationalité humaine

EnglishThis paper attempts to classify the different points of view regarding the question of cognitive biases and human rationality. Various epistemological positions are distinguished, from a

Students’ use of formalisations for improved logical reasoning

ABSTRACT Logical reasoning as part of critical thinking is becoming more and more important to prepare students for their future life in society, work, and study. This article presents the results of

Logical Misconceptions with Conditional Statements in Early Undergraduate Mathematics

Abstract We explore student performance on True-False assessments with statements in the conditional form “If P then Q” in order to better understand how students process conditional logic and to see



Misinterpretation of conditional statements in Wason's selection task

Two experiments using the experimental paradigm introduced by Gebauer and Laming in which subjects are given six problems in succession use the subset of cards selected by each subject as an indication of how the rule is understood and, when that selection is consistent throughout all six problems, a basis for evaluating the accuracy of the subject's reasoning according to three independent criteria.

Pragmatic Reasoning With a Point of View

Abstract Cheng and Holyoak (1985) proposed that realistic reasoning in deontic contexts is based on pragmatic schemas such as those for assessing compliance with or violation of permission and

Matching bias in conditional reasoning : Do we understand it after 25 years ?

The history of research and theorising on the problem in the subsequent 25 years is reviewed, including the effects of linguistic form, realistic content, and explicit negation on the matching bias on the specific processing-negations account.

Pragmatic versus syntactic approaches to training deductive reasoning

A little logic goes a long way: basing experiment on semantic theory in the cognitive science of conditional reasoning

It is concluded that semantic analyses have more direct benefits for psychological investigation than is usually credited, and conversely, that the extraordinary pragmatic circumstances of psychological experiments yield much thought provoking data for semantic analysis.

The task-specific nature of domain-general reasoning

Reasoning about a Rule

It is argued that the subjects did not give evidence of having acquired the characteristics of Piaget's “formal operational thought,” and it is suggested that the difficulty is due to a mental set for expecting a relation of truth, correspondence, or match to hold between sentences and states of affairs.

Reasoning about Conditional Promises and Warnings: Darwinian Algorithms, Mental Models, Relevance Judgements or Pragmatic Schemas?

It is proposed that reasoning about social contracts, such as conditional promises and warnings, is under the control of a compound schema made of two pragmatic schemas (Cheng & Holyoak, 1985),

Does Reasoning Occur on the Selection Task? A Comparison of Relevance-based Theories

Does reasoning occur on the Wason selection task, or are card selections determined purely on the basis of heuristic processes? To answer this question two relevance-based theories of reasoning are
