ERP记录从24名大学生，因为他们阅读的句子，已知不同的句法复杂性和工作记忆的要求，即对象和主题相关的句子。单词和多词分析都显示了由于句子类型的显着差异，而多词ERP也表明，句子类型的影响不同的好和差的henders。在单词水平上，客体关系句中两个动词的ERP在300 - 500 msec的词后出现左前负性，相对于那些主题关系动词，在多词水平上，缓慢的额叶正性特征的主题关系句，但不存在的客体关系句。这种缓慢的积极性似乎表明了加工或整合的容易程度，并且在良好的学习者中比在不良的学习者中更稳健。
ERPs were recorded from 24 undergraduates as they read sentences known to differ in syntactic complexity and working memory requirements, namely Object and Subject Relative sentences. Both the single-word and multiword analyses revealed significant differences due to sentence type, while multiword ERPs also showed that sentence type effects differed for Good and Poor comprehenders. At the single-word level, ERPs to both verbs in Object Relative sentences showed a left anterior negativity between 300 and 500 msec postword-onset relative to those to Subject Relative verbs, At the multiword level, a slow frontal positivity characterized Subject Relative sentences, but was absent for Object Relatives. This slow positivity appears to index ease of processing or integration, and was more robust in Good than in Poor comprehenders.
