先前的研究表明，在说普通话的先天性失乐症患者中，只有一个亚群存在行为词汇声调感知障碍（声调失认症），而其余的失乐症患者则没有。本研究的目的是调查有或没有行为词汇声调缺陷的普通话失乐者词汇声调感知的分类性质。三组听众（对照组、纯无音乐者和患有音调失认症的无音乐者）参与了音调识别和辨别任务。测量了从升调到平调的基频物理连续体的分类感知（CP）指数。具体来说，刺激持续时间被控制在 100 和 200 毫秒。对于这两种刺激持续时间，所有组都表现出相似的分类边界。纯无音乐表现出与正常对照类似的尖锐的识别斜率和显着峰值的辨别功能。然而，在患有声调失认症的失乐症患者中并没有观察到词汇声调 CP 的这种基本特征。将步长从 20 Hz 扩大到 35 Hz 也无法在音调不可知论中产生任何辨别峰值。目前的研究表明，只有患有音调失认症的无音乐者表现出缺乏分类音调感知，而纯无音乐者则表现出典型的词汇声调CP，这表明音乐中音高处理的缺陷并不一定导致词汇声调CP的缺陷。先天性失乐症伴音调失认症与不伴音调失认症的不同表现，为音乐与言语感知关系的命题提供了新的视角。
Previous research suggests that within Mandarin-speaking congenital amusics, only a subgroup has behavioral lexical tone perception impairments (tone agnosia), whereas the rest of amusics do not. The purpose of the current study was to investigate the categorical nature of lexical tone perception in Mandarin-speaking amusics with and without behavioral lexical tone deficits. Three groups of listeners (controls, pure amusics, and amusics with tone agnosia) participated in tone identification and discrimination tasks. Indexes of the categorical perception (CP) of a physical continuum of fundamental frequencies ranging from a rising to level tone were measured. Specifically, the stimulus durations were manipulated at 100 and 200 ms. For both stimulus durations, all groups exhibited similar categorical boundaries. The pure amusics showed sharp identification slopes and significantly peaked discrimination functions similar to those of normal controls. However, such essential characteristics for the CP of lexical tones were not observed in amusics with tone agnosia. An enlarged step-size from 20 to 35 Hz was not able to produce any discrimination peaks in tone agnosics either. The current study revealed that only amusics with tone agnosia showed a lack of categorical tone perception, while the pure amusics demonstrated typical CP of lexical tones, indicating that the deficit of pitch processing in music does not necessarily result in the deficit in the CP of lexical tones. The different performance between congenital amusics with and without tone agnosia provides a new perspective on the proposition of the relationship between music and speech perception.
