This study examines feedback-driven event-related potentials during conditional discrimination learning in a matching-to-sample task. By analyzing EEG responses to programmed consequences, we found that feedback presentation elicits distinct neural activity in the frontal regions. Moreover, differences in ERP latency and amplitude between correct and incorrect feedback were linearly related to participants’ test performance. These results offer insight into how the brain supports learning and the formation of conditional discrimination.
