The Influence Of Depressive Symptoms On Frn Amplitude: An Eeg Study, Jonathan Burton
The Influence Of Depressive Symptoms On Frn Amplitude: An Eeg Study, Jonathan Burton
USC Aiken Psychology Theses
Background: Individuals diagnosed with depression demonstrate differences in neural activation patterns detectable using electroencephalogram (EEG). One of these differences has been specifically linked with the event-related potential (ERP) component called feedback-related negativity (FRN). In participants diagnosed with depression, the FRN has been shown to have larger amplitudes in response to negative feedback. However, previous research has only specifically looked at the difference of this amplitude between groups, specifically those with and those without a diagnosis of depression. Objective: The goal of the current study was to examine whether a continuous range of depressive symptoms in participants can predict FRN amplitudes, …

Numerous studies have implicated the interaction of psychological distress and risky sexual behaviors in the increased risk of disease transmission, however, several studies have not found this association. It has been suggested that there may be curvilinear relationship between psychological distress and risky sexual behaviors but this theory has yet to be tested. The …
