Conferences 2008 - C. Bosc-Mine

Context effects in the complementary inference



Speaker : Christelle Bosc-Miné (IUFM d'Amiens)

Date: 8 november 2007

Summary:

Complementary inferences depend on the part-whole relation and are of special interest among deductive inferences since they play a decisive role in arithmetic additive problem solving. Conditions underlying the achievement of these inferences have been studied among 10 years old children in a simplified version of Mastermind, associated to a response program aimed at placing the participants in comparable situations. Three situations were compared: a non thematic situation, close to the usual version of Mastermind, an irrelevant thematic situation, relying on a narrative structure in which the semantic properties of the situation were not relevant for the complementary inference; and a relevant thematic situation, in which the part-whole dimension was made salient by the introduction of two exclusive categories. In accordance with our hypotheses, the complementary inferences were seldom achieved in the first two conditions (22 %, 11 %), and frequently in the third one (44 %). These results suggest that complementary inferences are facilitated by the realistic nature of the problem situations only if the semantic properties of the situations make salient a structure adapted to the application of the inference.
