We investigated whether speakers can use an internal channel to monitor their speech for taboo utterances and prevent these from being spoken aloud. Therefore event-related potentials were measured while participants carried out the SLIP task. In this task, speech errors were elicited that could either result in taboo words (taboo-eliciting trials) or neutral words (neutral-eliciting trials). In taboo-eliciting trials, there was an augmented negative wave around 600 ms after the pronunciation cue even though there were no overt errors. This component has previously been interpreted as reflecting conflict. These results indicate that taboo utterances can indeed be detected and corrected internally.
我们研究了说话者是否可以使用内部通道来监控他们的言语以避免说出禁忌词，并防止这些词被大声说出。因此，在参与者执行 SLIP 任务时测量了事件相关电位。在这个任务中，引发了可能导致禁忌词（禁忌诱发试验）或中性词（中性诱发试验）的言语错误。在禁忌诱发试验中，尽管没有明显的错误，但在发音提示后约 600 毫秒出现了增强的负波。这个成分以前被解释为反映冲突。这些结果表明，禁忌词确实可以被内部检测和纠正。
