Mismatch negativity, an index of automatic cerebral activity in response to novel stimuli, was used to determine the onset of morphosyntactic processing in French. Stimuli were four two-word sentences made up of a pronoun (first or second person) and a verb (first or second person). Verb forms differed only in the inflectional suffix, which made the sentences either syntactically correct or incorrect. The mismatch negativity response was found to be modulated by the grammaticality of the agreement relation at 50-140 ms after inflection onset, corroborating the previous finding that morphosyntactic processing occurs early and out of the focus of attention. The role of the pronoun-suffix association probabilities in determining the observed timing of morphosyntactic processing is discussed.
失匹配负波是大脑对新异刺激自动产生的活动指标，用于确定法语中形态句法加工的起始时间。刺激材料为四个由代词（第一或第二人称）和动词（第一或第二人称）构成的双词句子。动词形式仅在屈折后缀上有所不同，这使得句子在句法上要么正确要么错误。研究发现，在屈折开始后50 - 140毫秒，失匹配负波反应受到一致关系语法性的调节，这证实了之前的研究结果，即形态句法加工在早期就会发生且处于注意力焦点之外。本文还讨论了代词 - 后缀关联概率在确定形态句法加工观察到的时间中的作用。
