In two experiments, one with instrumental and one with synthesized tunes, 20 musicians and 20 non-musicians were requested to identify popular melodies presented dichotically. When the tempo of the melodies is fast enough to render their identification difficult, a right-ear advantage appears in the former group and a left-ear advantage in the latter, a pattern observed with both types of stimuli. It is suggested that these lateralization effects depend not only on the level of competence of the subjects, as hypothesized by Bever and Chiarello (Science, Vol. 185, pp. 537-539, 1974), but also on the musical features of the stimuli.
在两项实验中，一项使用器乐演奏的曲调，另一项使用合成曲调，要求20名音乐家和20名非音乐家辨别以双耳分听方式呈现的流行旋律。当旋律的节奏快到足以使其辨别变得困难时，前一组（音乐家）出现右耳优势，而后一组（非音乐家）出现左耳优势，两种类型的刺激都观察到了这种模式。研究表明，这些偏侧化效应不仅取决于受试者的能力水平，正如贝弗和基亚雷洛所假设的那样（《科学》，第185卷，第537 - 539页，1974年），还取决于刺激的音乐特征。
