Ideal representations in a similarity space


The present study provides an empirical evaluation of the ideal representation view of concept representation. We compared the ideal representation view with the more established exemplar and prototype views both in common taxonomic categories and in ad hoc categories. All three views are modeled based on underlying spatial similarity representations. Results suggest that the ideal representation is the better representation in ad hoc categories, and that the exemplar model is the better representation in the common taxonomic categories.
