最近的ERP研究报告称，不可信的动词-论元组合可能会引发中央-顶叶P600效应(例如，“丰盛的一餐正在吞噬……”；Kim&Osterhout，2005)。这种诱发条件不涉及明显的句法异常，与P600以前的报道不同。Kim和Osterhout(2005)将这种P600效应归因于结构再加工，当句法线索不能支持语义上有吸引力的解释时(‘Meal’作为‘吞噬’的施事)，句法线索被压倒，因此句子被认为是句法上的错误形式。目前的研究重复了这样的发现，还发现在这种句法-语义冲突的情况下改变句法线索(例如，“丰盛的一餐会吞噬……”)。影响冲突的结果。当句子包含需要多个形态合成步骤才能“修复”的句法线索时，P600被消除。这些句子在300-600毫秒(Lan)引起广泛的左前部负波。我们从句法线索对再加工的“抵抗”来解释P600波幅的降低。我们推测，局域网络可能是由于难以检索到同时满足句法和语义线索的分析而产生的，当句法线索足够强大，足以抵抗相反的语义线索时，就会产生这种情况。这种效应模式与部分独立但高度互动的句法和语义加工流是一致的，这些加工流通常是协同操作的，但可以竞争对口译的影响。(C)2011 Elsevier Inc.保留所有权利。
Recent ERP studies report that implausible verb-argument combinations can elicit a centro-parietal P600 effect (e.g., "The hearty meal was devouring ..."; Kim & Osterhout, 2005). Such eliciting conditions do not involve outright syntactic anomaly, deviating from previous reports of P600. Kim and Osterhout (2005) attributed such P600 effects to structural reprocessing that occurs when syntactic cues fail to support a semantically attractive interpretation ('meal' as the Agent of 'devouring') and the syntactic cues are overwhelmed; the sentence is therefore perceived as syntactically ill-formed. The current study replicated such findings and also found that altering the syntactic cues in such situations of syntax-semantics conflict (e.g., "The hearty meal would devour ...") affects the conflict's outcome. P600s were eliminated when sentences contained syntactic cues that required multiple morphosyntactic steps to "repair". These sentences elicited a broad, left-anterior negativity at 300-600 ms (LAN). We interpret the reduction in P600 amplitude in terms of "resistance" of syntactic cues to reprocessing. We speculate that the LAN may be generated by difficulty retrieving an analysis that: satisfies both syntactic and semantic cues, which results when syntactic cues are strong enough to resist opposing semantic cues. This pattern of effects is consistent with partially independent but highly interactive syntactic and semantic processing streams, which often operate collaboratively but can compete for influence over interpretation.
