- Description:
- Many theories of categorization have included an intuitive role for our ability to detect and judge similarity. Yet, this important role of similarity processing has been disputed. This research adopts a model of similarity processing through structure mapping (Gentner, 1983) to explore its role in similarity processing and categorization. Relational...
