Amplitude changes in the auditory event related response reflect differences in linguistic content and the level of processing of spoken sentences. Thus, the neurophysiology of the cognitive processes underlying speech perception can be evaluated by noninvasive techniques. Semantically correct, semantically incorrect, and grammatically incorrect sentences were processed either semantically or syntactically by 25 subjects while their EEGs were recorded. The amplitude of the P250 component to each word varied with processing level. A slow positive wave appeared after semantically correct sentences regardless of the linguistic processing level. N480 and P780 components were observed following words which made the sentences incorrect.
听觉事件相关反应中的振幅变化反映了语言内容的差异以及口语句子的加工水平。因此，可以通过非侵入性技术评估言语感知背后认知过程的神经生理学。25名受试者在进行语义或句法加工时记录其脑电图，加工的句子包括语义正确、语义错误和语法错误的句子。每个单词的P250成分的振幅随加工水平而变化。无论语言加工水平如何，在语义正确的句子之后都会出现一个缓慢的正波。在使句子错误的单词之后观察到N480和P780成分。
