目的：第二生殖性失音症是一种音高加工的神经遗传性疾病。它的语言后果已分别检查语音语调和词汇语调。然而，在汉语这样的声调语言中，语调和词汇语调的处理在在线语音感知过程中是相互作用的。音高障碍是否以及如何影响在线语音感知过程中的语言音高加工尚不清楚。方法采用语调（疑问句与陈述句）和词汇语调（升调2与降调4）识别任务，使用同一组句子对该问题进行研究，比较普通话音乐和匹配对照的行为和事件相关电位测量结果。我们特别关注没有行为词汇音调缺陷的音乐（大多数，即纯音乐）。结果纯音乐被试在词汇语调测试中表现较差，但在句子语调和语调识别中表现较差。与对照组相比，纯音乐在音调任务中具有较大的N400振幅，而在语调任务中具有较小的P600振幅。结论音高障碍对纯音乐在句子加工过程中的声调和语调加工均有影响，而纯音乐的词汇声调加工在单词测试中是完整的。
PurposeCongenital amusia is a neurogenetic disorder of musical pitch processing. Its linguistic consequences have been examined separately for speech intonations and lexical tones. However, in a tonal language such as Chinese, the processing of intonations and lexical tones interacts with each other during online speech perception. Whether and how the musical pitch disorder might affect linguistic pitch processing during online speech perception remains unknown.MethodWe investigated this question with intonation (question vs. statement) and lexical tone (rising Tone 2 vs. falling Tone 4) identification tasks using the same set of sentences, comparing behavioral and event-related potential measurements between Mandarin-speaking amusics and matched controls. We specifically focused on the amusics without behavioral lexical tone deficits (the majority, i.e., pure amusics).ResultsResults showed that, despite relative to normal performance when tested in word lexical tone test, pure amusics demonstrated inferior recognition than controls during sentence tone and intonation identification. Compared to controls, pure amusics had larger N400 amplitudes in question stimuli during tone task and smaller P600 amplitudes in intonation task.ConclusionThese data indicate that musical pitch disorder affects both tone and intonation processing during sentence processing even for pure amusics, whose lexical tone processing was intact when tested with words.
