本文采用事件相关电位研究方法探讨了汉语语篇加工中语境诱发的话题性的本质。话题是话语所表达的内容，是最突出的话语成分。我们测试了由主题和非主题问题组成的问答对，然后是不同的延续（主题连续性，主题转移，新主题）。在不同的位置测量ERPs，并显示，前一个初始信息处理的主题，影响N400和晚积极性效应一样。在非初始位置，新的区别是主导原则，也调节N400和后期积极性。因此，语言处理器利用一些核心操作进行信息处理，这些操作取决于特定位置的约束。(C)2012爱思唯尔爱尔兰有限公司保留所有权利。
We report an event-related potential study designed to explore the nature of context-induced topicality in Chinese discourse processing. Topic is what an utterance is about and represents the most prominent discourse element, which occurs sentence-initially in Chinese. We tested question-answer pairs consisting of topic and non-topic questions followed by different continuations (Topic-Continuity, Topic-Shift, Novel-Topic). ERPs were measured at distinct sentential positions and revealed that sentence-initially information processing is guided by topicality, which affects N400 and Late Positivity effects alike. In non-initial positions, the given-new distinction is the dominant principle, also modulating N400 and Late Positivity. The language processor hence utilizes a few core operations for information processing that depend on position-specific constraints. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
