The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing

The analysis of response-locked event-related potential (ERP) waveforms from several experiments points to the existence of a neural system involved in processing information associated with errors in choice reaction time tasks. The experiments included a sentence verification task, a Sternberg memory search task, and two letter discrimination tasks. In all these experiments, a negative-going deflection (the error-related negativity, or ERN) in the event-related brain potential began around the time of error onset and peaked about 100 msec later. It ranged in amplitude from 3 to 10 microvolts, was bilaterally symmetrical, and had a scalp distribution maximal at central and frontal electrode sites. The ERN was not evident on correct trials.
