The faculty in the Brain & Cognitive Science (BCS) area of the Psychology department seek to understand the mental processes and structures that are involved in perceiving, learning, understanding, and acting in ones environment. The mental phenomena that we study include basic visual processes, categorization, decision making, spatial cognition, cognitive and motor skills, perception-action links, and higher-order cognition. We use a variety of methods, ranging from behavioral measurements (e.g., reaction time experiments) to mathematical modeling, to neurophysiological measurements (i.e. single-cell recording).
