研究发现，动词体对事件知识的激活有影响，有4个新的结果。首先，事件的常见位置(例如，竞技场)被标记在具有不完成体的动词之后(例如，是滑冰)，而不是具有完成体的动词(例如，曾经滑冰)。其次，与完成体的句子片段相比，人们产生的处所介词短语更多地作为完成体的句子片段的补语。第三，N400成分对处所名词的幅度随体和典型性的不同而不同，对于预期位置较高的非完成句，其幅度最小，对于位置较低的非完成句，其幅度最大。第四，介词短语在完成体之后的额面持续负性的幅度比不完成体之后的大。综上所述，这些发现表明，事件知识和语言流之间存在着动态的相互作用。
The authors show that verb aspect influences the activation of event knowledge with 4 novel results. First, common locations of events (e.g., arena) are primed following verbs with imperfective aspect (e.g., was skating) but not verbs with perfect aspect (e.g., had skated). Second, people generate more locative prepositional phrases as completions to sentence fragments with imperfective than those with perfect aspect. Third, the amplitude of the N400 component to location nouns varies as a function of aspect and typicality, being smallest for imperfective sentences with highly expected locations and largest for imperfective sentences with less expected locations. Fourth, the amplitude of a sustained frontal negativity spanning prepositional phrases is larger following perfect than following imperfective aspect. Taken together, these findings suggest a dynamic inter-play between event knowledge and the linguistic stream.
