Developmental changes in the reward positivity: An electrophysiological trajectory of reward processing

Children and adolescents learn to regulate their behavior by utilizing feedback from the environment but exactly how this ability develops remains unclear. To investigate this question, we recorded the event-related brain potential (ERP) from children (8–13 years), adolescents (14–17 years) and young adults (18–23 years) while they navigated a “virtual maze” in pursuit of monetary rewards. The amplitude of the reward positivity, an ERP component...
