AN EXEMPLAR APPROACH TO CONCEPTUAL COMBINATION

Despite the success of exemplar models of representation, the general approach in the study of the representation of conceptual combinations is based on pro-totypes. In this study, we evaluate the exemplar view in conceptual combina-tion, and compare it to the traditional prototype approach. For 10 complex con-cepts, typicality was predicted using an instantiation-based spatial exemplar model. The exemplar model’s predictions were compared to the predictions of five plausible prototype models. Results clearly indicated that the exemplar model provides the best predictions of typicality for the complex concepts, and little or no unique variance in the observed typicality gradient was accounted for exclusively by the prototype model. We find that an exemplar representa-tion of five to ten exemplars is optimal in the prediction of typicality, which is remarkably similar to earlier findings regarding simple, established concepts. Following the clear dominance of exemplar models in categorisation and con-cept research, the present study underlines the need of taking the exemplar approach to the next level, applying it in the more complex field of conceptual combination
