The paper reports an electrophysiological (EEG) study investigating how language is involved in perception-action relations in musically trained and untrained participants. Using an original backward priming paradigm, participants were exposed to muted point-light videos of violinists performing piano or forte nuances followed by a congruent vs. incongruent word. After the video presentation, participants were asked to decide whether the musician was playing a piano or forte musical nuance. EEG results showed a greater P200 event-related potential for trained participants at the occipital site, and a greater N400 effect for untrained participants at the central site. Musically untrained participants were more accurate when the word was semantically congruent with the gesture than when it was incongruent. Overall, language seems to influence the performance of untrained participants, for which perception-action couplings are less automatized.
本文报告了一项关于电生理学（EEG）的研究，该研究旨在探讨音乐训练和非训练参与者的感知-动作关系中语言是如何参与其中的。研究采用原创的反向启动范式，让参与者观看一段静音的小提琴家演奏钢琴或强音的点光视频，之后呈现一个与视频内容一致或不一致的单词。在视频呈现后，参与者被要求判断音乐家演奏的是钢琴还是强音音乐的细微差别。EEG 结果显示，在枕叶部位，受过训练的参与者的 P200 事件相关电位更大，而在中央部位，未受过训练的参与者的 N400 效应更大。当单词与手势在语义上一致时，未受过音乐训练的参与者的表现更准确，而当单词与手势不一致时，他们的表现则较差。总的来说，语言似乎影响了未受过训练的参与者的表现，因为他们的感知-动作耦合不太自动化。
