先天性失语症是一种神经遗传性疾病，会影响说英语和法语等非声调语言的人的音高处理。我们评估了这种音乐障碍是否存在于说普通话的人中，他们使用音高来改变单词的意思。使用蒙特利尔失调症评估小组，我们测试了117名自称没有音乐问题的说普通话的健康年轻人和22名报告有音乐困难的人，他们的得分比说普通话但没有失调症的人的平均值低两个标准差。这22名失语者表现出与非声调语言失调者相似的音乐障碍模式，表现出比节奏处理更明显的旋律缺陷。此外，近一半的受试者在辨别和识别普通话词汇声调方面存在缺陷。其中6人表现出明显的障碍，表现出可以被称为词汇声调失认的症状，但音调产生正常。我们的结果表明，说普通话等声调语言的人可能会经历音高障碍，尽管他们很早就接触到了与语音相关的音高对比。观察到的音乐障碍和词汇音调困难之间的联系表明，定义先天性失忆的音调障碍并不是音乐或文化特有的，而是相当普遍的。
Congenital amusia is a neurogenetic disorder that affects the processing of musical pitch in speakers of non-tonal languages like English and French. We assessed whether this musical disorder exists among speakers of Mandarin Chinese who use pitch to alter the meaning of words. Using the Montreal Battery of Evaluation of Amusia, we tested 117 healthy young Mandarin speakers with no self-declared musical problems and 22 individuals who reported musical difficulties and scored two standard deviations below the mean obtained by the Mandarin speakers without amusia. These 22 amusic individuals showed a similar pattern of musical impairment as did amusic speakers of non-tonal languages, by exhibiting a more pronounced deficit in melody than in rhythm processing. Furthermore, nearly half the tested amusics had impairments in the discrimination and identification of Mandarin lexical tones. Six showed marked impairments, displaying what could be called lexical tone agnosia, but had normal tone production. Our results show that speakers of tone languages such as Mandarin may experience musical pitch disorder despite early exposure to speech-relevant pitch contrasts. The observed association between the musical disorder and lexical tone difficulty indicates that the pitch disorder as defining congenital amusia is not specific to music or culture but is rather general in nature.
