事件相关脑电位(ERPs)被用来研究语义因素(生命性)如何以及何时影响对一个复杂句法结构的早期分析，即宾语相关句子。我们对比了两种对象相关类型的电生理和行为反应，这两种类型在句法和词汇上是相同的，只是在构成有生命和无生命的名词的顺序上有所不同[无生命(有生命的)和有生命的(无生命的)]。从40名受试者中记录了30个I(A)和30个A(I)句中每个单词的事件相关电位，这些句子是在一组不同的句子类型中随机出现的，以供理解。事件相关电位对早期名词有生命操作的影响被观察到，从最初的名词开始，延伸到主句动词之后。我们将包括N400、P600和左前部负波在内的电生理效应的时序和多发性解释为语义和句法的证据，也许还有其他类型的信息，在结构分析和消息水平计算的早期被用于理解。
Event-related brain potentials (ERPs) were used to investigate how and when a semantic factor (animacy) affects the early analysis of a difficult syntactic structure, namely, object relative sentences. We contrasted electrophysiological and behavioral responses to two object relative types that were syntactically and lexically identical and varied only in the order of the component animate and inanimate nouns [Inanimate (Animate) vs. Animate (Inanimate)]. ERPs were recorded from 40 subjects to each word of 30 I(A) and 30 A(I) sentences that occurred randomly among a set of various other sentence types read for comprehension. ERP effects to the early noun animacy manipulation were observed beginning with the initial noun and extending past the main clause verbs. We interpret the timing and multitude of electrophysiological effects, including the N400, P600, and left-anterior negativity, as evidence that both semantic and syntactic, and perhaps other types of information, are used early during structural analysis and message-level computations as needed for comprehension.
