Locating Biomarkers in OCD Through Behavioral Tasks

Subjects that have a diagnosis of OCD will participate in a clinical interview and cognitive tasks, during which they will be exposed to their individual OC stressors or will be asked to make decisions related to information value and quantity while measuring neural activity and filming facial reactions. This will assist investigators to look for biomarkers of that change. This study offers a unique opportunity to develop biomarkers for key domains of OCD, and other neuropsychiatric disorders, that are grounded in brain neurocircuitry at the individual-patient level. Subjects will participate in a clinical interview (Day 1), and then tasks+EEG (Day 2). Day 1 will be 4 hours or less, and Day 2 will be 2.5 hours or less.
