既可用作名词又可用作动词的单词会产生句法歧义区域，这可能会给听者带来处理挑战。然而，声学特性，如持续时间，在这些词的名词和动词使用之间是不同的，并且听众可以使用这些差异来促进歧义处理。在这项研究中，我们用动词代替了名词的歧义词，以确定这些操作是否影响了N400事件相关电位，这是与语义违规，或P600组件，这是与句法歧义。结果表明，名词/动词多义词之间的声学差异减轻这些词被认为是模棱两可的程度，虽然结果并不表明是否取代一个与其他产生的意义侵犯。名词/动词多义词的时长差异可能影响其在流利言语中的加工。
Words that can be used as both noun and verb create regions of syntactic ambiguity that could create processing challenges for listeners. However, acoustic properties, such as duration, differ between noun and verb uses of such words, and listeners may use these differences to facilitate ambiguity processing. In this study, we replaced noun uses of ambiguous words with verb uses to determine whether these manipulations affected the N400 event-related potential, which is associated with semantic violations, or the P600 component, which is associated with syntactic ambiguity. The results suggest that the acoustic differences between noun/verb polysemes mitigate the extent to which these words are perceived as ambiguous, although the results do not indicate whether replacing one with the other produces a meaning violation. Durational differences in noun/verb polysemes may affect their processing in fluent speech.
