To explore the relationship between the processing of melodic and rhythmic patterns in speech and music, we tested the prosodic and musical discrimination abilities of two "amusic" subjects who suffered from music perception deficits secondary to bilateral brain damage. Prosodic discrimination was assessed with sentence pairs where members of a pair differed by intonation or rhythm, and musical discrimination was tested using musical-phrase pairs derived from the prosody of the sentence pairs. This novel technique was chosen to make task demands as comparable as possible across domains. One amusic subject showed good performance on both linguistic and musical discrimination tasks, while the other had difficulty with both tasks. In both subjects, level of performance was statistically similar across domains, suggesting shared neural resource for prosody and music. Further tests suggested that prosody and music may overlap in the processes used to maintain auditory patterns in working memory.
为了探究言语和音乐中旋律与节奏模式处理之间的关系，我们测试了两名“失歌症”受试者的韵律和音乐辨别能力，这两名受试者因双侧脑损伤而存在音乐感知缺陷。我们通过句子对评估韵律辨别能力，其中一对句子的成员在语调或节奏上存在差异，并且使用从句子对的韵律中衍生出的音乐短语对来测试音乐辨别能力。选择这种新颖的技术是为了使不同领域的任务要求尽可能具有可比性。一名失歌症受试者在语言和音乐辨别任务上均表现良好，而另一名在两项任务上都存在困难。在两名受试者中，不同领域的表现水平在统计学上相似，这表明韵律和音乐共享神经资源。进一步的测试表明，韵律和音乐在用于维持工作记忆中听觉模式的过程中可能存在重叠。
