Recent work has identified the anterior cingulate cortex (ACC) as a key component in a neural system involved in reinforcement learning and error processing. According to a recent theory, the ACC is activated by the impact of dopaminergic reward prediction signals that are elicited when the basal ganglia detect unexpected response errors or negative feedback (Holroyd & Coles, 2002; Psych Review). This theory suggests that performance errors and negative feedback should give rise to activation of a common area in ACC. To test this prediction, we conducted an fMRI experiment in which participants performed a probabilistic learning task. This task allowed a within-subject comparison of the neural activation associated with speeded response errors and that associated with unpredicted negative feedback. Consistent with our prediction, the results revealed a common area in dorsal ACC that was more active following incorrect responses than following correct responses, and more active following negative feedback than following positive feedback. The same ACC area also responded strongly on correct trials associated with high response conflict. Response errors also engaged the pre-SMA, but this area was not differentially engaged by negative feedback. Negative feedback was associated with reduced activity in basal ganglia and orbitofrontal cortex. The finding that response errors and negative feedback activate a common area in dorsal ACC is consistent with the view that scalp-recorded electrophysiological negativities observed following errors and negative feedback (i.e., error-related negativities) are generated in the same region in ACC.
