目前的研究采用事件相关电位（ERP）来检查在分类照应词解析过程中词汇语义和话语信息整合的时间过程。构建的场景包括三个潜在的前因。照应词在语义上是不明确的，因为两个潜在的先行词是照应词的范例。最后的句子用正确的（联想相关的/上下文合适的）、不正确的（联想相关的/上下文不合适的）或控制先行词（联想不相关的/上下文不合适的）来解析照应词。我们检查了 N400 分量的幅度，这被认为反映了照应词后面几个点的语义整合的难易程度。当文本在照应词后面提到正确的先行词时，会唤起最小的 N400；中间的 N400 是由不正确的先行词引起的，最大的 N400 是通过在照应词之后恢复控制先行词来引起的。结果表明，在模棱两可的照应词之后，读者能够使用词汇语义和语篇层面的信息将先行词在语义上整合到其更大的语篇上下文中。
The present studies employed event-related potentials (ERPs) to examine the time course for the integration of lexico-semantic and discourse information during the resolution of categorical anaphors. Scenarios were constructed to include three potential antecedents. Anaphors were semantically ambiguous in that two of the potential antecedents were exemplars of the anaphor. Final sentences resolved the anaphor with the correct ( associatively related/contextually appropriate), incorrect ( associatively related/contextually inappropriate), or control antecedent ( associatively unrelated/contextually inappropriate). We examined the amplitude of the N400 component, which is thought to reflect the ease of semantic integration, at several points following the anaphor. The smallest N400 was evoked when the text referred back to a correct antecedent following an anaphor; an intermediate N400 was evoked by incorrect antecedents and the largest N400 was evoked by reinstating the control antecedent following an anaphor. Results demonstrated that, following an ambiguous anaphor, readers are able to use both lexico-semantic and discourse-level information to semantically integrate an antecedent into its larger discourse context.
