dc.description.abstractThe current study examined differences in the levels of two event-related potentials (ERPs), error-related negativity (ERN) and medial frontal negativity (MFN), in patients with a primary diagnosis of obsessive-compulsive disorder (OCD) and control participants. It was hypothesized that OCD participants would show more negative ERN and MFN peaks than control participants would. Participants performed a gambling task and a version of the Eriksen Flanker Task (Eriksen & Eriksen, 1974) while their neural activity was recorded using an electroencephalogram (EEG). Although a small sample size (n = 2 for both Control and OCD groups) did not allow for statistical analysis, promising preliminary data have been found to support hypotheses that OCD participants did show more negative ERN and MFN peaks as well as a longer latency in comparison to control patients. These findings support previous research that suggests the OCD is caused by an over-active error signaling system (e.g., Pitman, 1987).en_US
