Abstract Individual differences in reward responsiveness can be reliably measured at the neurophysiological level using the reward positivity (RewP) event-related potential (ERP). Alterations in reward responsiveness impact physical and psychological health. In particular, prior research indicates that a reduced RewP prospectively predicts depressive symptoms. However, it remains unclear whether RewP can be modified through intervention or prevention. The present study examined the effects of a ...

Exposure to social stress is a well-established risk factor for the development and recurrence of depression. Reduced neural responsiveness to monetary reward has been associated with greater symptoms following stress exposure. It remains unclear whether reduced reward responsiveness serves as a mediator or moderator of the effects of stress on internalizing symptoms or whether similar patterns emerge with responses to social reward. We addressed this issue by measuring lifetime stress exposure ...
