Clinical Psychophysiology

Research Summary:

Psychophysiological approaches to human emotion and cognition. Currentstudies utilize event-related brain potential (ERP) components to study cognitive characteristics of patients with anxiety disorders such as OCD and social phobia.  Specifically, we use error-related negativity (ERN) to study response and error monitoring in adult and pediatric OCD patients and the P300 to study attribution biases in social phobia.  In our newest set of experiments, we are exploring the utility of late positive potentials (LPP) and more traditional autonomic nervous system measures to study self-regulation of positive and negative emotional reactions to emotion-provoking pictures.  Much or our work with anxiety patients is done in collaboration with Edna Foa at the Center for the Treatment and Study of Anxiety at the University of Pennsylvania.
