Differentiating stages of reward responsiveness: Neurophysiological measures and associations with facets of the behavioral activation system.

ABSTRACT: The Research Domain Criteria (RDoC) positive valence systems domain include multiple aspects of reward responsiveness with potential to elucidate the understanding of motivational and hedonic deficits in psychological disorders. There is a need for reliable and valid methods to delineate behavioral and biological processes underlying stages of reward responsiveness. Event-related potentials (ERPs) offer a promising method for examining the temporal dynamics of reward processing, but the literature has mainly focused on the feedback stage and often single components. We investigated the electrophysiological aspects of reward anticipation and initial response to reward using an ERP monetary incentive delay task in 114 emerging adults. Principal component analysis was used to derive temporall
