A NEURAL SYSTEM FOR ERROR-DETECTION AND COMPENSATION

Humans can monitor actions and compensate for errors. Analysis of the human event-related brain potentials (ERPs) accompanying errors provid es evidence for a neural process whose activity is specifically associ ated with monitoring and compensating for erroneous behavior. This err or-related activity is enhanced when subjects strive for accurate perf ormance but is diminished when response speed is emphasized at the exp ense of accuracy. The activity is also related to attempts to compensa te for the erroneous behavior.
