语义是语言的一个关键特征，但音乐是否能激活与语义处理相关的大脑机制尚不清楚。我们比较了语言和音乐中的语义加工，考察了语义启动效应，以行为测量和脑电(EEG)测量的事件相关脑电位(ERP)的N400分量为指标。人类受试者在听到一个口头句子或一段音乐节选后，被呈现在视觉上的目标词。与主句语义无关的目标词比前面有语义相关句的目标词产生的N400更大。此外，语义上不相关的音乐前置的目标词与相关的音乐前置的目标词相比，显示出相似的N400效应。语言和音乐的N400启动效应在时间进程、强度或神经产生方面没有差异。我们的结果表明，音乐和语言都可以启动一个词的意义，音乐作为语言可以决定语义加工的生理指标。
Semantics is a key feature of language, but whether or not music can activate brain mechanisms related to the processing of semantic meaning is not known. We compared processing of semantic meaning in language and music, investigating the semantic priming effect as indexed by behavioral measures and by the N400 component of the event-related brain potential (ERP) measured by electroencephalography (EEG). Human subjects were presented visually with target words after hearing either a spoken sentence or a musical excerpt. Target words that were semantically unrelated to prime sentences elicited a larger N400 than did target words that were preceded by semantically related sentences. In addition, target words that were preceded by semantically unrelated musical primes showed a similar N400 effect, as compared to target words preceded by related musical primes. The N400 priming effect did not differ between language and music with respect to time course, strength or neural generators. Our results indicate that both music and language can prime the meaning of a word, and that music can, as language, determine physiological indices of semantic processing.
