Abstract

Event-related potentials (ERPs) of error trials in choice tasks and Go/Nogo tasks are found to be considerably different from the ERPs of the correct trials: In error trial ERPs there is an additional negative(N-e) and an additional positive component (P-e) compared to correct trials. Amplitude and latency variation of both components in different experiments supports the hypothesis that these components reflect different aspects of error processing. The N-e is interpreted as a real-time correlate of error detection, as defined by a mismatch between cognitive representations of the erroneous response and the correct response. The variation of P-e with experimental variables is different from that of the N-e and it also from that of positive components in correct trials, and may therefore reflect an additional aspect of error processing, such as change of response strategies.
