事件相关电位和眼动追踪被用于研究句子理解中启动效应的本质。参与者阅读两个句子（一个启动句和一个目标句），这两个句子都具有困难且模糊的句子结构。启动句和目标句包含相同的动词或意义非常相近的动词。当动词重复时，启动效应显著。在事件相关电位实验中，在跟随含有相同动词的启动句的目标句中，P600的波幅降低，但在含有同义动词的启动句中则没有。在眼动追踪实验中，当目标句跟随含有相同动词的启动句时，消除歧义区域的总阅读时间减少，但当目标句跟随含有同义动词的启动句时则没有减少。动词重叠在简化的关系从句中极大地增强了启动效应这一事实可能表明动词论元结构在在线句法分析中起着重要作用。
Event-related potentials and eye tracking were used to investigate the nature of priming effects in sentence comprehension. Participants read 2 sentences (a prime sentence and a target sentence), both of which had a difficult and ambiguous sentence structure. The prime and target sentences contained either the same verb or verbs that were very close in meaning. Priming effects were robust when the verb was repeated. In the event-related potential experiment, the amplitude of the P600 was reduced in target sentences that followed prime sentences with the same verb but not in prime sentences with a synonymous verb. In the eye-tracking experiment, total reading times on the disambiguating region were reduced when the targets followed prime sentences with the same verb but not when targets followed prime sentences with a synonymous verb. The fact that verb overlap greatly boosted priming effects in reduced relative sentences may indicate that verb argument structures play an important role in online parsing.
