Feedback-related neurophysiology in children and their parents: Developmental differences, familial transmission, and relationship to error-monitoring.

The feedback negativity (FN) and reward positivity (RewP) are event-related brain potentials (ERPs) that follow the presentation of negative and positive feedback information, respectively, and have become the focus of recent research on psychopathology because of their associations with symptom severity of and risk for depression. We advanced our understanding of these feedback-related ERPs by examining developmental differences, familial transmission, and associations with error-monitoring ERPs. Parents and their children completed parallel, developmentally-tailored guessing and go/no-go tasks while feedback- and error-related ERPs were measured. We found that the Δ FN and RewP amplitudes increased with age and were larger in males than females among the child participants. The RewP also demonstrated familial transmission between fathers and their children. Finally, the FN and RewP were associated with error-related ERPs in children and adults, albeit in different ways. The current findings demonstrate that the FN and RewP have promise as developmentally-sensitive neural markers of reward and action monitoring processes associated with risk for psychopathology.
