    The processing of negations in conditional reasoning: A meta-analytic case study in mental model and/or mental logic theory.Walter J. Schroyens, Walter Schaeken & Géry D'Ydewalle - 2001 - Thinking and Reasoning 7 (2):121-172.
    We present a meta-analytic review on the processing of negations in conditional reasoning about affirmation problems (Modus Ponens: “MP”, Affirmation of the Consequent “AC”) and denial problems (Denial of the Antecedent “DA”, and Modus Tollens “MT”). Findings correct previous generalisations about the phenomena. First, the effects of negation in the part of the conditional about which an inference is made, are not constrained to denial problems. These inferential-negation effects are also observed on AC. Second, there generally are reliable effects of (...)

    Working memory and everyday conditional reasoning: Retrieval and inhibition of stored counterexamples.Wim De Neys, Walter Schaeken & Géry D'Ydewalle - 1995 - Thinking and Reasoning 11 (4):349-381.
    Two experiments examined the contribution of working memory (WM) to the retrieval and inhibition of background knowledge about counterexamples (alternatives and disablers, Cummins, ) during conditional reasoning. Experiment 1 presented a conditional reasoning task with everyday, causal conditionals to a group of people with high and low WM spans. High spans rejected the logically invalid AC and DA inferences to a greater extent than low spans, whereas low spans accepted the logically valid MP and MT inferences less frequently than high (...)

    Strategies during complex conditional inferences.Kristien Dieussaert, Walter Schaeken, Walter Schroyens & Gery D'Ydewalle - 2000 - Thinking and Reasoning 6 (2):125 – 160.
    In certain contexts reasoners reject instances of the valid Modus Ponens and Modus Tollens inference form in conditional arguments. Byrne (1989) observed this suppression effect when a conditional premise is accompanied by a conditional containing an additional requirement. In an earlier study, Rumain, Connell, and Braine (1983) observed suppression of the invalid inferences "the denial of the antecedent" and "the affirmation of the consequent" when a conditional premise is accompanied by a conditional containing an alternative requirement. Here we present three (...)

    Conditional reasoning with negations: Implicit and explicit affirmation or denial and the role of contrast classes.Walter Schroyens, Niki Verschueren, Walter Schaeken & Gery D'Ydewalle - 2000 - Thinking and Reasoning 6 (3):221 – 251.
    We report two studies on the effect of implicitly versus explicitly conveying affirmation and denial problems about conditionals. Recently Evans and Handley (1999) and Schroyens et al. (1999b, 2000b) showed that implicit referencing elicits matching bias: Fewer determinate inferences are made, when the categorical premise (e.g., B) mismatches the conditional's referred clause (e.g., A). Also, the effect of implicit affirmation (B affirms not-A) is larger than the effect of implicit denial (B denies A). Schroyens et al. hypothesised that this interaction (...)

    Truth table tasks: The relevance of irrelevant.Géry D'Ydewalle, Walter Schaeken, Kristien Dieussaert, Walter Schroyens & Aline Sevenants - 2008 - Thinking and Reasoning 14 (4):409-433.
    Two types of truth table tasks are used investigating mental representations of conditionals: a possibilities-based and a truth-based one. In possibilities tasks, participants indicate whether a situation is possible or impossible according to the conditional rule. In truth tasks participants evaluate whether a situation makes the rule true or false, or is irrelevant with respect to the truth of the rule. Comparing the two-option version of the possibilities task with the truth task in Experiment 1, the possibilities task yields logical (...)

    International Perspectives on Psychological Science, Ii: The State of the Art.Paul Bertelson, Paul Eelen & Gery D'Ydewalle - 1994 - Psychology Press.
    The essays appearing in these two volumes are based on Keynote and State-of-the-Art Lectures delivered at the XXVth International Congress of Psychology, in Brussels, July 1992. The Brussels Congress was the latest in a series of conferences which are organized at regular intervals under the auspices of the International Union of Psychological Science, the main international organization in the field of Scientific Psychology. The first of those meetings took place in Paris in 1889. An important function of the International Congresses (...)
