A Functional Neuroimaging Study Of Self-Regulatory Control In Adults With Gambling And Obsessive-Compulsive Disorders, Nidhi Parashar

Dissertations, Theses, and Capstone Projects

Objective: Recent findings suggest phenomenological similarities across gambling and obsessive-compulsive disorders. The key similarity between the disorders is the failure to inhibit or control a repetitive behavior (or urges to engage in a behavior) and intrusive thoughts. Our current understanding of the neural pathophysiological mechanisms linking gambling and obsessive-compulsive disorders is limited. Thus, the aim of the present study was to examine the functioning of frontostriatal brain regions that support self-regulatory control in adults with gambling and obsessive-compulsive disorders.

Methods: The study compared functional magnetic resonance imaging blood oxygen level dependent response in 19 adults with pathological gambling (PG), …

Stereotype Threat As An Explanation For Sexual Risk Taking Behavior In Gay Men: A Multi-Study Exploration Of Mechanisms, Inna Saboshchuk

Stereotype threat is a hindrance in performance that occurs when an individual’s awareness of negative stereotypes associated with his/her group results in inadvertent conforming to that stereotype. Stereotype threat research has been conducted on myriad group and domain identifications but gay men are strikingly absent from the stereotype threat literature. One of the most prevalent stereotypes about gay men indicates they are sexually promiscuous and that this promiscuity is linked to HIV infection. In a series of three research projects, a theoretical model proposing stereotype threat as a mechanism for sexual risk taking behavior in gay men is tested. In …
