通过对比不同句法复杂程度的句子与违反句法的句子的事件相关电位（ERPs），研究了句法复杂程度和句法修复的关系。先前的研究表明，句法加工的这两个方面都反映在后期的肯定性中（P600）。然而，本实验的结果表明，虽然两个加工方面都诱发了一个后期正性，但它们在分布上是不同的。与修复相关的阳性反应在阴性反应前表现为中央-顶叶分布，而与复杂性相关的阳性反应则表现为前额-中央头皮分布。这些数据表明，P600不是一个单一的现象。此外，这种分布差异强烈表明，不同的神经结构导致了句法修复和句法整合困难这两个方面的加工，在处理句法复杂句时最为明显。
Aspects of syntactic complexity and syntactic repair were investigated by comparing the event-related (brain) potentials (ERPs) for sentences of different syntactic complexity to those containing a syntactic violation. Previous research had shown that both aspects of syntactic processing are reflected in a late positivity (P600). Results from the present reading experiment demonstrate, however, that although both processing aspects elicit a late positivity they are different in distribution. The repair-related positivity preceded by a negativity displayed a centroparietal distribution, whereas the complexity-related positivity showed a frontocentral scalp distribution. These data indicate that the P600 is not a unitary phenomenon. Moreover, the distributional differences strongly suggest that different neural structures underlie the two aspects of processing, namely syntactic repair and syntactic integration difficulties, most evident when processing syntactically complex sentences.
