Our laboratory is currently exploring interactions between perceptual and conceptual learning, methods for learning abstract concepts using computer simulations, the perception of similarity and analogy, and group behavior from a complex systems perspective.

Most of my current research interests involve the representation and learning of concepts. I conduct psychological experiments on people's acquisition of visually presented concepts, interactions between developing concepts, the influence of concepts on perception, and concept specialization/differentiation. I develop computer simulations (often times, neural network models) to model concept formation and the two-way interaction between our conceptual and perceptual systems.

In other lines of research, I study judgment, decision making, and comparison processes involving similarity and analogy. I am also interested in educational applications of cognitive psychology.
