Abstract:
Action errors can occur when routine responses are triggered inappropriately by familiar cues. Here, EEG was recorded as volunteers
performed a ?go/no-go? task of long duration that occasionally and unexpectedly required them to withhold a frequent,
routine response. EEG components locked to the onset of relevant go trials were sorted according to whether participants erroneously
responded to immediately subsequent no-go trials or correctly withheld their responses. Errors were associated with a
significant relative reduction in the amplitude of the preceding P300, that is, a judgement could be made bout whether a responseinhibition
error was likely before it had actually occurred. Furthermore, fluctuations in P300 amplitude across the task formed a
reliable associate of individual error propensity, supporting its use as a marker of sustained control over action.
