在视觉中，全局（整体）特征通常在局部（细节）特征之前处理（“全局优先效应”）。然而，在听觉域中，全局和局部处理之间的区别不太清楚。本研究的目的是调查：（一）定向与分散注意力的影响，（二）音乐训练对16名成年音乐家和16名非音乐家的听觉全局-局部处理的影响。研究人员向参与者展示了短的九音旋律，每个旋律由三个三音序列（三音单元）组成。在一项“定向注意”任务中，参与者被要求关注全局或局部音高模式，并必须确定音高模式是上升还是下降。在“分散注意力”任务中，参与者判断目标模式（向上或向下）是否存在。总体而言，全球结构被认为是更快，更准确地比本地结构。无论注意力是否指向特定水平或在水平之间划分，都观察到全局优先效应。总体而言，音乐家比非音乐家表现得更准确，但非音乐家表现出更明显的全球优势。这项研究提供了证据的听觉全局优先效应在注意任务，并与音乐体验相关的听觉全局-局部处理的差异。(C)2012年美国声学学会。[http：//dx.doi.org/10.1121/1.4747009]
In vision, global (whole) features are typically processed before local (detail) features ("global precedence effect"). However, the distinction between global and local processing is less clear in the auditory domain. The aims of the present study were to investigate: (i) the effects of directed versus divided attention, and (ii) the effect musical training on auditory global-local processing in 16 adult musicians and 16 non-musicians. Participants were presented with short nine-tone melodies, each comprised of three triplet sequences (three-tone units). In a "directed attention" task, participants were asked to focus on either the global or local pitch pattern and had to determine if the pitch pattern went up or down. In a "divided attention" task, participants judged whether the target pattern (up or down) was present or absent. Overall, global structure was perceived faster and more accurately than local structure. The global precedence effect was observed regardless of whether attention was directed to a specific level or divided between levels. Musicians performed more accurately than non-musicians overall, but non-musicians showed a more pronounced global advantage. This study provides evidence for an auditory global precedence effect across attention tasks, and for differences in auditory global-local processing associated with musical experience.
