    Precursors of logical concepts in preverbal infants: the case of disjunctive syllogism

     

    A growing body of recent results suggests that infants perform sophisticated hypothesis testing. These findings are often considered as evidence for infants' flexibility to generate hypotheses about future uncertain events or for their ability to identify alternative hypotheses when a contradiction is detected. But are infants actually able to capture the relation between alternatives in logical terms? Studying the logical operators available for such purposes may contribute not only to our understanding of the origins of rationality but also regarding the nature of knowledge acquisition. Despite the relevance of this issue, given the presumed prolonged development of logical reasoning and its embeddedness into language, infant logic, till very recently was believed to have little or no psychological reality. Here I will present a series of experiments with preverbal infants - snapshots from a larger project targeting infants’ rational inferences - that aim to identify the precursors of logical concepts at a preverbal age. I will focus on different implementations of disjunctive syllogisms, cases that involve simple problems that range from rule extraction, to communicative and searching behavior and to preference attribution.
