ABSTRACT

Research has shown that observers often spontaneously extract a mean representation from multiple faces/objects in a scene even when this is not required by the task. This phenomenon, now known as ensemble coding, has so far mainly been based on data from Western populations. This study compared East Asian and Western participants in an implicit ensemble-coding task, where the explicit task was to judge whether a test face was present in a briefly exposed set of faces. Although both groups showed a tendency to mistake an average of the presented faces as target, thus confirming the universality of ensemble coding, East Asian participants displayed a higher averaging tendency relative to the Westerners. To further examine how a cultural default can be adapted to global or local processing demand, our second experiment tested the effects of priming global or local processing orientation on ensemble coding via a Navon task procedure. Results revealed a reduced tendency for ensemble coding following the priming of local processing orientation. Together, these results suggest that culture can influence the proneness to ensemble coding, and the default cultural mode is malleable to a temporary processing demand.

平均身份提取中的文化差异:全球与本地加工方向的作用

摘要

研究表明,即使任务不需要,观察者也经常自发地从场景中的多个面部/对象中提取均值表示。到目前为止,这种现象现在称为集合编码,主要是基于西方人群的数据。这项研究将东亚和西方参与者在隐式整体编码任务中进行了比较,其中显式任务是判断在短暂暴露的面孔集中是否存在测试面孔。尽管两组都显示出将平均出现的面孔误认为是目标的趋势,从而确认了整体编码的普遍性,但相对于西方人,东亚参与者表现出更高的平均趋势。为了进一步研究文化默认值如何适应全球或本地处理需求,我们的第二个实验通过Navon任务程序测试了启动全局或局部处理方向对合奏编码的影响。结果显示,在启动局部加工方向后,合奏编码的趋势降低。总之,这些结果表明,文化可能会影响合奏编码的倾向,默认文化模式可适应临时的处理需求。
