本研究采用事件相关脑电位实验研究了话语中句子加工过程中指称因素和结构因素的相互作用。受试者阅读以“大卫告诉那个女孩.”开头的（荷兰语）句子。“在短篇小说的上下文中，为一个关键的单数名词短语（“女孩”）引入了一个或两个所指对象。波形显示，在280毫秒内发生的关键名词后，读者已经确定是否名词短语有一个独特的所指在早期的话语。此外，这一参考信息立即被用于分析句子的其余部分，这是一个补充条款（“.会有一些访客”）和一个关系从句（“.一直在电话上挂断的人”）。一个一致的模式P600/SPS的影响引起的各种随后的消歧显示，一个双指话语背景下，导致解析器最初追求的关系从句替代在更大程度上比一个单指的情况下。总之，研究结果表明，在话语中的句子处理过程中，信息的结构和参考来源在一个词一个词的基础上相互作用。(C)北京：科学出版社.
An event-related brain potentials experiment was carried out to examine the interplay of referential and structural factors during sentence processing in discourse. Subjects read (Dutch) sentences beginning like "David told the girl that..." in short story contexts that had introduced either one or two referents for a critical singular noun phrase ("the girl"). The waveforms showed that within 280 ms after onset of the critical noun the reader had already determined whether the noun phrase had a unique referent in earlier discourse. Furthermore, this referential information was immediately used in parsing the rest of the sentence, which was briefly ambiguous between a complement clause ("...that there would be some visitors") and a relative clause ("...that had been on the phone to hang up"). A consistent pattern of P600/SPS effects elicited by various subsequent disambiguations revealed that a two-referent discourse context had led the parser to initially pursue the relative-clause alternative to a larger extent than a one-referent context. Together, the results suggest that during the processing of sentences in discourse, structural and referential sources of information interact on a word-by-word basis. (C) 1999 Academic Press.
