In a previous study, the pattern of ear superiority displayed by nonmusicians in a task where dichotically presented target melodies have to be recognized among four probes was found to be correlated with subjects' descriptions of their operating modes: those who reported focusing on critical local differences in pitch tended to show right ear advantage (REA) and the others LEA. The purpose of the present study was to examine if laterality patterns can be affected by treatments designed to induce particular strategies. Treatments supposed to orient toward analytic processing, advising attention to critical notes, with (Experiment 2) or without (Experiment 1) the additional task of reporting their location, produced the expected shift toward REA. To the contrary, treatments supposed to orient toward holistic processing, advising attention to overall contour or requesting aesthetic judgments (Experiment 1), failed to produce the expected shift toward LEA. The result can be attributed either to a basic difference in susceptibility to strategic control between the different operating modes or, more simply, to ineffectiveness of the present holistically oriented treatments.
在之前的一项研究中，研究人员发现，在一项需要在四个探测音中识别两耳分听呈现的目标旋律的任务中，非音乐家表现出的耳优势模式与受试者对其操作模式的描述相关：那些报告专注于音高关键局部差异的人往往表现出右耳优势（REA），而其他人则表现出左耳优势（LEA）。本研究的目的是检验偏侧性模式是否会受到旨在诱导特定策略的处理的影响。旨在引导进行分析处理、建议关注关键音符的处理方式，在有（实验2）或没有（实验1）报告音符位置这一额外任务的情况下，都产生了预期的向REA的转变。相反，旨在引导进行整体处理、建议关注整体轮廓或要求进行审美判断的处理方式（实验1），未能产生预期的向LEA的转变。这一结果要么可归因于不同操作模式在对策略控制的敏感性上存在根本差异，要么更简单地说，可归因于当前以整体为导向的处理方式无效。
