ABSTRACT

Causal or deep features of concepts have been found to play an important role in categorization judgments. Individuals are more likely to categorize based on a matching cause than matching effects. Causal features can be characterized as those that give rise to or explain the surface features of a concept, such as perceptual or behavioral attributes. The present research explored how the presence of shared deep and surface features affects other types of induction, specifically, the projection of new attributes or information to a novel case. Further, deep-feature matches were judged to be more similar, and had a greater impact on categorization judgments, in that a novel disease was more likely to be classified as an instance of the known disease when it had a matching deep versus a matching surface feature.
