本研究获得了言语加工的事件相关脑电位效应，并与句子阅读的类似效应进行了比较。三、两个实验的口语句子在句尾或句中位置呈现语义违反。对于这些违反，获得的N400效应非常类似于在阅读中获得的N400效应。然而，言语中的N400效应之前是较早的负性（N250）。这种消极性在书面输入中并不常见。早期效应被解释为基于上下文预期的单词形式与基于语音信号生成的激活单词候选者的实际队列之间的不匹配的表现。(C)2000爱思唯尔科技有限公司版权所有。
In this study, event-related brain potential effects of speech processing are obtained and compared to similar effects in sentence reading. III two experiments spoken sentences were presented with semantic violations in sentence-final or mid-sentence positions. For these violations N400 effects were obtained that were very similar to N400 effects obtained in reading. However, the N400 effects in speech were preceded by an earlier negativity (N250). This negativity is not commonly observed with written input. The early effect is explained as a manifestation of a mismatch between the word forms expected on the basis of the context, and the actual cohort of activated word candidates that is generated on the basis of the speech signal.
