A monaural study of music perception was conducted on 77 right-handed subjects from a university population. The musical ability of each subject was classified in two ways, according to years of training and by total score for three tests of musical achievement [melody (sequence and excerpt), harmony, and rhythm]. Analysis indicated that subjects with more years of training showed a right-car dominance for recognition of excerpts but those with high scores had no such dominance. Both groups with either low scores or no formal training had a right-ear dominance for recognition of sequences. Correlations of scores from each ear within subjects and between tests indicated that perception of pitch tended to be more accurate in the same car. For all classifications of subjects no ear dominance was found for harmony and rhythm tests. These results suggest that the measurement of hemispheric asymmetry of music perception is dependent upon the criteria chosen for classification of subjects, in this case, training and achievement.
对来自大学人群的77名右利手受试者进行了音乐感知的单耳研究。根据训练年限和音乐成就三项测试（旋律（序列和片段）、和声和节奏）的总分，以两种方式对每个受试者的音乐能力进行了分类。分析表明，训练年限较长的受试者在识别片段时表现出右耳优势，但得分高的受试者则没有这种优势。得分低或未接受过正规训练的两组受试者在识别序列时均表现出右耳优势。受试者双耳得分之间以及测试之间的相关性表明，在同一耳中，音高感知往往更准确。对于所有受试者分类，在和声和节奏测试中均未发现耳优势。这些结果表明，音乐感知半球不对称性的测量取决于为受试者分类所选择的标准，在本研究中即训练和成就。
