我们报告的第一个记录的情况下，先天性失乐症。这种障碍是指不能用先前的脑损伤、听力损失、认知缺陷、社会情感障碍或缺乏环境刺激来解释的音乐残疾。这种音乐障碍是在一名中年妇女，以下简称莫妮卡，谁缺乏最基本的音乐能力，包括旋律的歧视和识别，尽管正常的听力和高于平均水平的智力，记忆力和语言技能。心理物理测试的结果表明，莫妮卡在检测音高变化方面有严重的困难。这些数据表明，音乐处理的困难可能会导致细粒度的歧视音高的问题，就像许多语言处理的困难产生的听觉时间分辨率的不足。
We report the first documented case of congenital amusia. This disorder refers to a musical disability that cannot be explained by prior brain lesion, hearing loss, cognitive deficits, socioaffective disturbance, or lack of environmental stimulation. This musical impairment Is diagnosed in a middle-aged woman, hereafter referred to as Monica, who lacks most basic musical abilities, including melodic discrimination and recognition, despite normal audiometry and above-average intellectual, memory, and language skills. The results of psychophysical tests show that Monica has severe difficulties with detecting pitch changes. The data suggest that music-processing difficulties may result from problems in fine-grained discrimination of pitch, much in the same way as many language-processing difficulties arise from deficiencies in auditory temporal resolution.
