Research Interests

The goal of my research is to understand the mechanisms involved in the development of psychosis and to use that understanding to improve our ability to predict and prevent future psychosis. Most social-cognitive models of psychosis have included two specific components: Aberrant salience (i.e., the unusual or incorrect assignment of significance or importance to stimuli, which is thought to be associated with dopamine dysregulation; Kapur, 2003) and self-processing (i.e., the way in which an individual processes information related to the self). My research program focuses on: (a) defining and measuring the constructs of aberrant salience and psychotic-like experiences; (b) examining the relations between self-processing and psychotic and psychotic-like experiences; and (c) investigating the interaction between aberrant salience and self-processing in psychosis. My research uses questionnaire and interview assessments of psychotic symptoms, basic social cognitive neuroscience tasks to measure aberrant salience and self-processing, experimental psychopathology paradigms to understand normal and abnormal belief formation, and advanced statistical techniques to examine the factor structure of psychotic-like experiences.
