当被试在选择反应时间任务中犯错误时出现的事件相关电位称为“错误负性”（Ne， ERN），是反应监测的标志。通过引入响应概率偏差，我们证明了Ne对响应期望很敏感。我们进一步表明，正确反应（Ne-like， CRN）引起的小负性对反应期望也很敏感：在意外反应中，前者减少，后者增加，以至于两个分量的幅度在同一幅度内。尽管Ne对响应预期的敏感性与考虑Ne的当前模型是兼容的，但Ne和类Ne的共同敏感性支持了它们反映功能相似的监测过程的观点。
The event-related potential called "Error Negativity" (Ne, ERN), which appears when subjects commit errors in choice reaction time tasks, is a marker of response monitoring. By introducing a response probability bias, we show that the Ne is sensitive to response expectancy. We further show that the small negativity evoked by correct responses (Ne-like, CRN) is also sensitive to response expectancy: On unexpected responses, the former decreases while the latter increases to such an extent that the amplitudes of the two components are in the same range of magnitude. Although the sensitivity of the Ne to response expectancy is compatible with the current models accounting for the Ne, the common sensitivity of the Ne and the Ne-like supports the idea that they reflect functionally similar monitoring processes.
