Structure implicative des propriétés, conséquences pour l'étude de la catégorisation

We show how the notion of implication between properties and the relevance principle shed new light on the results of Rosch and her colleagues (1975, 1976). To uncover our hypotheses, concerning relationships between properties, participants were asked to respond to propositions linking properties A and B, relative to birds, of the type “If A, can it generally be said that B?” Results show that some properties are linked one to the other (quasi-equivalence, quasi-implication, or quasi-independence) and that these implicative links can be summarized by an implicative graph. The resulting property structure has a predictive character for participant response times.
