音乐对语言加工的影响——来自ERP的证据

ERP Evidence for the Effect of Music on Language Processing

向音乐人和非音乐人分别同时呈现句末词有无词类范畴违反的句子,和结尾和弦有无和弦句法违反的和弦序列,并采用ERP(event-related potential,事件相关电位)技术观察被试音乐加工对句子加工的影响。结论是,汉语句子和和弦序列的句法整合加工之间似乎共享神经资源。这两种句法整合加工机制性质相同,能相互促进。音乐训练对语言和音乐句法整合加工的神经资源共享性有调节作用。

In order to examine the influence of music processing on sentence reading in Chinese,an ERP(event-related potentials)study was conducted on a group of musicians and a cohort of non-musicians,in which the language and music stimuli were presented simultaneously.The language stimuli were Chinese sentences which ended with number-classifier-noun collocations or number-classifier-verb clusters,and the music stimuli were chord sequences which ended with in-key or out-of-key chords.The out-of-key chords elicited larger early right anterior negativity(ERAN),syntactic category violation in sentence reading resulted in larger N400 and P600,and only the amplitude of P600 was affected by musical syntactic processing.In comparison with the non-musicians,the musicians had a larger ERAN and an attenuated P600,and their distributions of N400 and P600 were more left-oriented.In conclusion,the processing of Chinese number-classifier-noun collocations and that of chord sequences share the syntactic integration resources by enrolling two interactive neural mechanisms,which could be modulated by music training.
