在音高和词汇音调的加工中，认知资源共享的程度仍然不确定。测试普通话助兴者对普通话词汇声调的类别感知，可以提供对这一问题的深入了解。在本研究中，一组15个amusic普通话说话人识别和区分普通话声调连续在单独的块。所用的声调连续体是从高声调到中升调和从高声调到高降调。这两个声调连续统是在自然语言和非语言类比的背景下产生的。与对照组相比，失乐症的参与者对跨越语音或非语言类似物分类边界的辨别对没有改善，表明缺乏分类感知。在音乐组中缺乏对普通话音调的分类感知表明，音乐中的音高缺陷可能是领域普遍的，这表明音乐音高和词汇音调的处理可能共享某些认知资源和/或过程（Patel 2003，2008，2012）。
The degree to which cognitive resources are shared in the processing of musical pitch and lexical tones remains uncertain. Testing Mandarin amusics on their categorical perception of Mandarin lexical tones may provide insight into this issue. In the present study, a group of 15 amusic Mandarin speakers identified and discriminated Mandarin tones presented as continua in separate blocks. The tonal continua employed were from a high-level tone to a mid-rising tone and from a high-level tone to a high-falling tone. The two tonal continua were made in the contexts of natural speech and of nonlinguistic analogues. In contrast to the controls, the participants with amusia showed no improvement for discrimination pairs that crossed the classification boundary for either speech or nonlinguistic analogues, indicating a lack of categorical perception. The lack of categorical perception of Mandarin tones in the amusic group shows that the pitch deficits in amusics may be domain-general, and this suggests that the processing of musical pitch and lexical tones may share certain cognitive resources and/or processes (Patel 2003, 2008, 2012).
