Event-related potentials were recorded from 13 scalp locations while participants read sentences containing a syntactic ambiguity. In Experiment 1, syntactically disambiguating words that were inconsistent with the "favored" syntactic analysis elicited a positive-going brain potential (P600). Experiment 2 examined whether syntactic ambiguities are resolved by application of a phrase-structure-based minimal attachment principle or by word-specific subcategorization information. P600 amplitude was a function of subcategorization biases rather than syntactic complexity. These findings indicate that such biases exist and can influence the parser under certain conditions and that P600 amplitude is a function of the perceived syntactic well-formedness of the sentence.
在参与者阅读包含句法歧义的句子时，从13个头皮位置记录与事件相关的电位。在实验1中，与“偏好”句法分析不一致的句法消除歧义的单词引发了正向脑电位（P600）。实验2研究了句法歧义是通过应用基于短语结构的最小附着原则还是通过特定单词的次范畴化信息来解决的。P600波幅是次范畴化偏好的函数，而不是句法复杂性的函数。这些发现表明，这种偏好是存在的，并且在某些条件下会影响句法剖析器，而且P600波幅是句子感知到的句法合格性的函数。
