Multiple systems of category learning are behaviorally and neurally dissociable. Declarative memory guides learning of rules via hypothesis testing. Procedural memory guides learning of skills by associating percepts with specific motor responses.

Principled method to construct models of behavior constrained by neurophysiology.

GRT is a multidimensional extension of signal detection theory, useful for studying whether multiple perceptual elements interact as we make decisions about them.

During initial learning we can distinguish between declarative and procedural mechanisms, but these differences disappear with extended training. Quicker and more direct neural pathways take over as automaticity develops.

Dynamical Neuroscience is an interdisciplinary field that is focused on the study of how the nervous system generates perception, behavior and cognition. It is a computational approach that goes beyond traditional structure/function correlations. Its subdisciplines include molecular and cellular biology, genetics, computer science, artificial intelligence, nonlinear systems, statistical processes, physics and aspects of psychology. The UCSB campus has superb standing faculty in all of these academic disciplines. For more information  click here.

Undergraduates have the opportunity to participate as a Research Assistant (RA) by enrolling in PSY 99 or PSY 199. Please contact Yi-Wen for current openings and briefly introduce yourself, including your skills and knowledge that might be relevant to our research. A strong background in math, statistics and programming is a plus.
