The purpose of this study was to investigate the effect of music ear training upon the auditory discrimination abilities of 30 institutionalized trainable mentally retarded (TMR) adolescents. Subjects were 15 TMRs enrolled in choir and 15 TMRs who were not choir members. The hypothesis was that music ear training incorporated in choir rehearsals would enhance auditory discrimination abilities, as measured by the Goldman-Fristoe-Woodcock Test of Auditory Discrimination. An analysis of variance revealed significantly more errors in auditory discrimination by the TMR adolescents not enrolled in choir. Results of t tests comparing the scores of TMR choir members to Goldman-Fristoe-Woodcock test norms for the same chronological age revealed significantly more errors by the choir members. However, t tests comparing the performance of TMR choir members and Goldman-Fristoe-Woodcock test norms for normal subjects of the same mental age revealed significantly more errors by normal subjects.
本研究的目的是调查音乐听力训练对30名在机构中接受训练的可训练智力迟钝（TMR）青少年听觉辨别能力的影响。受试者为15名参加唱诗班的TMR青少年和15名非唱诗班成员的TMR青少年。假设是，纳入唱诗班排练的音乐听力训练将提高听觉辨别能力，这通过戈德曼-弗里斯托-伍德科克听觉辨别测试来衡量。方差分析显示，未参加唱诗班的TMR青少年在听觉辨别方面的错误明显更多。将TMR唱诗班成员的分数与相同实际年龄的戈德曼-弗里斯托-伍德科克测试标准进行比较的t检验结果显示，唱诗班成员的错误明显更多。然而，将TMR唱诗班成员的表现与相同心理年龄的正常受试者的戈德曼-弗里斯托-伍德科克测试标准进行比较的t检验显示，正常受试者的错误明显更多。
