EXTENDED ABSTRACT - In this research we examine the use of categories in reasoning, or more specifically, how individuals use information about one set of categories to make inferences about (or generalize to) another category. In particular we focus on the nonmonotonicity phenomenon (Osherson et al. 1990), examining how information about a competitor’s product can weaken inferences about a brand’s products under different conditions. We examine this category-based induction phenomenon in a pair of studies that investigated some of the factors, including the similarity of the competitor’s product and the type of attribute information, that might mediate the effect.
