Mondor and Bryden [8] (Neuropsychologia 29, 1179-1190, 1991) reported that the normal Right Ear Advantage for the identification of verbal material presented dichotically could be largely eliminated if subjects were cued to attend to and report from only one ear on each trial. In these experiments, the ear to be attended was cued by presentation of a tone to that ear only prior to each dichotic trial. The present series of studies were undertaken to determine whether this lateralized tone cue exerted its effect by orienting attention or by alerting the subject of the forthcoming trial. Results revealed that for both the right and left ears the facilitating effect of the cue was dependent on the accuracy of the location information it conveyed. Thus, the precueing technique originally employed by Mondor and Bryden as a means of controlling the contribution of attention to ear advantages was validated. It is concluded that the precueing technique provides a powerful means for specification of the extent to which attentional factors and hemispheric functional capabilities contribute to ear asymmetries.
蒙多尔和布赖登[8]（《神经心理学》第29卷，第1179 - 1190页，1991年）报告称，如果在每次试验中提示受试者只关注并报告一只耳朵，那么在双耳分听呈现言语材料时正常的右耳优势会在很大程度上被消除。在这些实验中，在每次双耳分听试验之前，仅通过向那只耳朵呈现一个音调来提示要关注的耳朵。进行本系列研究是为了确定这种单侧音调提示是通过引导注意力还是通过提醒受试者即将进行的试验来发挥作用。结果显示，对于右耳和左耳，提示的促进作用都取决于它所传达的位置信息的准确性。因此，蒙多尔和布赖登最初采用的预提示技术作为一种控制注意力对耳优势贡献的手段得到了验证。得出的结论是，预提示技术为明确注意力因素和半球功能能力对耳不对称性的贡献程度提供了一种有力手段。
