先天性失乐症是一种神经发育障碍，可能会影响音乐音调和词汇声调的处理。在本研究中，我们检查了三组普通话母语听众的声调轮廓变化的恰显差异（JND）：有（音调不可知论者）和没有词汇声调困难（纯无乐者）的无音乐者，以及匹配的对照组。音调不可知论者的 JND 明显大于正常对照组，而纯无音乐论者的表现与对照组相当。这些结果表明，只有那些具有行为词汇音调缺陷的无音乐人士可能在音高轮廓辨别方面受到心理物理损害。
Congenital amusia is a neuro-developmental disorder that may affect the processing of both music pitch and lexical tone. In the present study, the just-noticeable differences (JNDs) of tone pitch contour change were examined for three groups of Mandarin-native listeners: amusics with (tone agnosics) and without lexical tone difficulties (pure amusics), and matched controls. Tone agnosics showed significantly larger JNDs than normal controls, while pure amusics performed comparably with the controls. These results suggest that only those amusics with behavioral lexical tone deficits might be psychophysically impaired in pitch contour discrimination.
