This study investigated the interaction of prosody and thematic fit/plausibility information during the processing of sentences containing temporary early closure (correct) or late closure (incorrect) syntactic ambiguities using event-related potentials (ERPs). Early closure sentences with congruent and incongruent prosody were presented where the temporarily ambiguous NP was either a plausible or an implausible continuation for the subordinate verb (e.g. "While the band played the song/beer pleased all the customers."). N400 and P600 components were examined at critical points in each condition. The CPS was examined in sentences with congruent prosody. Prosodic and thematic fit cues interacted immediately (N400-P600) at the implausible NP (), when it was paired with incongruent prosody. Incongruent prosody paired with a plausible NP () resulted in garden-path effects (N400-P600) at the critical verb (). These findings provide strong evidence that prosodic and thematic fit/plausibility cues interact to aid the parser in syntactic structure building.
本研究使用事件相关电位（ERP），调查了在处理包含临时早期闭合（正确）或晚期闭合（不正确）句法歧义的句子过程中，韵律与主题契合度/合理性信息之间的相互作用。呈现了具有一致和不一致韵律的早期闭合句子，其中临时歧义的名词短语（NP）对于从属动词而言，要么是合理的延续，要么是不合理的延续（例如，“当乐队演奏歌曲/啤酒取悦了所有顾客。”）。在每种条件下的关键点处，对N400和P600成分进行了检查。在韵律一致的句子中对CPS进行了检查。当不合理的NP与不一致的韵律配对时，韵律和主题契合线索在该不合理的NP处立即（N400 - P600）相互作用。不一致的韵律与合理的NP配对，在关键动词处产生了花园路径效应（N400 - P600）。这些发现提供了强有力的证据，表明韵律和主题契合/合理性线索相互作用，以帮助句法分析器构建句法结构。
