Recent research has suggested that there is a component of the event-related brain potential, the error-related negativity (ERN), that is associated with error detection and remedial actions such as error inhibition, immediate error correction, or error compensation. The present experiment used a go/no-go task to define more precisely the functional significance of this component. In this task, an ERN was observed for incorrect responses on go trials (errors of choice) and for responses on no-go trials (errors of action). Because errors of action cannot be corrected immediately by executing another response, these results indicate that the process manifested by the ERN is not dependent on immediate error correction. Other aspects of the data converge in suggesting that the ERN process is more closely related to error detection and that the connections between detection and remedial actions may depend on the task situation.
最近的研究表明，事件相关脑电位的一个成分，即错误相关负波（ERN），与错误检测及诸如错误抑制、即时错误纠正或错误补偿等补救行动有关。本实验采用了一个Go/No-Go任务来更精确地界定该成分的功能意义。在这个任务中，对于Go试验中的错误反应（选择错误）以及No-Go试验中的反应（行动错误）都观察到了ERN。由于行动错误无法通过执行另一个反应立即得到纠正，这些结果表明，ERN所体现的过程并不依赖于即时错误纠正。数据的其他方面也都表明，ERN过程与错误检测的关系更为密切，并且检测与补救行动之间的联系可能取决于任务情境。
