    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 (...)

    The relevance of selecting what's relevant: A dual process approach to transitive reasoning with spatial relations.Eef Ameel, Niki Verschueren & Walter Schaeken - 2007 - Thinking and Reasoning 13 (2):164 – 187.
    The present paper focuses on the heuristic selection process preceding the actual transitive reasoning process. A part of the difficulty of transitive reasoning lies in the selection of the relevant problem aspects. Two experiments are presented using the paradigm introduced by Markovits, Dumas, and Malfait (1995), in which children were asked to make “higher than” inferences about arrays of coloured blocks. In order to discriminate between genuine transitive inference and a simple strategy of relative position, Markovits et al. interspersed white (...)
