Research Interests


My research is organized around the development and testing of formal mathematical and computer-simulation models of category learning and representation. The main competing models that drive the research include exemplar-storage and retrieval models as well as abstract rule-based models. Tests of the models have involved studying detailed relations between categorization performance and other fundamental cognitive processes, including identification, old-new recognition, similarity judgment, and the development of automaticity.
