句法加工是音乐理解的基础。虽然和声句法的加工已经得到了很好的研究，但对节奏句法加工的神经机制知之甚少。本研究探讨了节奏句法的神经加工以及长期音乐训练是否以及在多大程度上影响这种加工。14名音乐家和14名非音乐家听句法规则或句法不规则的节奏序列，并判断这些序列的完整性。与音乐家一样，非音乐家对句法不规则结尾也表现出P600效应，这表明音乐接触和对音乐的感知学习足以使非音乐家在后期处理节奏句法。然而，音乐家，而不是非音乐家，也表现出早期右前负性（ERAN）反应的句法不规则的结尾，这表明音乐训练只调节早期，而不是后期的节奏句法处理。这些发现首次揭示了音乐节奏句法加工的神经机制，对音乐认知的层次结构理论以及音乐句法加工与语言句法加工的比较研究具有重要意义。
Syntactic processing is essential for musical understanding. Although the processing of harmonic syntax has been well studied, very little is known about the neural mechanisms underlying rhythmic syntactic processing. The present study investigated the neural processing of rhythmic syntax and whether and to what extent long‐term musical training impacts such processing. Fourteen musicians and 14 nonmusicians listened to syntactic‐regular or syntactic‐irregular rhythmic sequences and judged the completeness of these sequences. Nonmusicians, as well as musicians, showed a P600 effect to syntactic‐irregular endings, indicating that musical exposure and perceptual learning of music are sufficient to enable nonmusicians to process rhythmic syntax at the late stage. However, musicians, but not nonmusicians, also exhibited an early right anterior negativity (ERAN) response to syntactic‐irregular endings, which suggests that musical training only modulates the early but not the late stage of rhythmic syntactic processing. These findings revealed for the first time the neural mechanisms underlying the processing of rhythmic syntax in music, which has important implications for theories of hierarchically organized music cognition and comparative studies of syntactic processing in music and language.
