Gratitude has been shown to reduce economic impatience. In particular, individuals induced to experience heightened gratitude are more willing to choose delayed larger rewards over immediate smaller rewards (i.e., they have lower discounting rates) than those in a neutral condition. Using the event-related potential (ERP) method, we investigated the relation between gratitude level and neurophysiological correlates. Of interest was motivated information processing, as indexed by the P3 component. Participants were administered a gratitude or a neutral mood induction followed by a temporal discounting task (choosing between a fixed immediate reward versus a future reward that varied across trials) while electroencephalogram …

Rumination is a construct that cuts across a variety of disorders, including anxiety and depression. It has been associated with deficits in cognitive control thought to confer risk for psychopathology. One aspect of cognitive control that is especially relevant to the content of ruminative thoughts is error processing. We examined the relation of rumination and 2 electrophysiological indices of error processing, error related negativity (ERN), an early index of error detection, and error positivity (Pe), a later index of error awareness. Consistent with prior work, ERN was negatively correlated with anxiety (i.e., more anxious individuals were characterized by larger ERNs). …
