  1. Implicit learning in rule induction and problem solving.Aldo Zanga & Jean-Fran - 2004 - Thinking and Reasoning 10 (1):55 – 83.
    Using the Chinese Ring Puzzle, we studied the effect on rule discovery of having to plan actions or not in order to reach a goal state. This was done by asking participants to predict legal moves as in implicit learning tasks and by asking participants to make legal moves as in problem-solving tasks. Our hypothesis was that having a specific goal state to reach has a dual effect on rule discovery. The first effect is positive and related to feedback from (...)

  2. Modus tollens, modus shmollens: Contrapositive reasoning and the pragmatics of negation. Jean-Fran - 2007 - Thinking and Reasoning 13 (2):207 – 222.
    The utterance of a negative statement invites the pragmatic inference that some reason exists for the proposition it negates to be true; this pragmatic inference paves the way for the logically unexpected Modus Shmollens inference: “If p then q ; not- q ; therefore, p.” Experiment 1 shows that a majority of reasoners endorse Modus Shmollens from an explicit major conditional premise and a negative utterance as a minor premise: e.g., reasoners conclude that “the soup tastes like garlic” from the (...)

  3. Defective truth tables and falsifying cards: Two measurement models yield no evidence of an underlying fleshing-out propensity. Jean-Fran - 2008 - Thinking and Reasoning 14 (3):231 – 243.
    Using a latent variable modelling strategy we study individual differences in patterns of answers to the selection task and to the truth table task. Specifically we investigate the prediction of mental model theory according to which the individual tendency to select the false consequent card (in the selection task) is negatively correlated with the tendency to judge the false antecedent cases as irrelevant (in the truth table task). We fit a psychometric model to two large samples ( N = 486, (...)
