Dissociation between categorization and similarity judgement: differential effect of causal status on feature weights

Show Summary Details

Preview

Given that most investigators agree that categorization can be based on an expanded definition of similarity, elucidating the mechanism underlying dissociations between similarity and categorization judgements becomes important. The purpose of this chapter is to introduce one way of distinguishing deep versus surface features and then show how this framework explains dissociations between categorization and similarity. First, the chapter reviews previous demonstrations of dissociations between similarity and categorization. Next, it presents a new set of evidence showing a specific mechanism by which dissociations between similarity and categorization occur.

Keywords: categorization; similarity judgement; dissociation; causal status; feature weights; non-causal condition
