C. Brendan Clark Ph.D.

My research focuses on cooperation, trust, and fairness. I am interested in measuring these aspects of social behavior through behavioral economic assessments with the goals of determining which patterns are more successful in different environments and learning how these social behaviors differ in those with mental illnesses. The majority of my work has been done with individuals in the criminal justice system; however, I have recently begun working with Major Depressive Disorder, Antisocial Personality Disorder, and Anxiety Disorders.

Research Interests: Cooperation, Behavioral Economics, Personality Disorders, and Criminal Justice
