目前的ERP研究检查了音乐和音调语言中音高处理的神经基础，这些语言的短语以一致或不一致的音高结尾。在声调语言中，如中文，音高是词汇相关的，因为它可以改变单词的含义，因此可以假设在这种情况下音高信息的处理不同于音乐音高。中国女音乐家被选为听众，因为她们对音乐和音调语言有充分的了解。音高违规在这两个领域都与一个正面分布的晚期正分量（LPC）。除了唤起语言条件的N400之外，LPC所揭示的音高处理对于音调语言是左侧化的，对于音乐是右侧化的。我们提出，我们的数据可能意味着不同的大脑资源参与音高处理取决于其功能是否是词汇，如在音调语言，如中文，或音乐的性质。
The current ERP study examined the neural substrates for pitch processing in music and in tonal language with phrases ending in either congruous or incongruous pitches. In a tonal language, like Chinese, pitch is lexically relevant as it can change the meaning of words, and it could therefore be hypothesized that pitch information under this condition is processed differently from musical pitch. Female Chinese musicians were chosen as listeners for their ample exposure to music and a tonal language. Pitch violations in both domains were associated with a frontally distributed late positive component (LPC). In addition to evoking an N400 for language condition, pitch processing as revealed by the LPCs is left lateralized for tonal language and right lateralized for music. We propose that our data may imply different brain resources engaging in pitch processing depending on whether its function is lexical, as in a tonal language like Chinese, or musical in nature.
