People are able to rapidly extract summary statistical information about common patterns, or ensembles, that may exist in a scene, such as repeated textures or colors. Here we examined the extent to which such an ensemble perception can occur in the absence of focal visual attention using a method that has some advantages over methods previously used to study the issue. In particular, we assessed the extent to which ensembles can be processed without attention by measuring the indirect effect of a to-be-ignored ensemble on judgments of an attended ensemble. The results show that ensembles outside the focus of attention do influence judgments of attended ensembles when the to-be-ignored ensemble contains summary statistics that match a sought-for target category. Thus, an attentional control setting for specific summary statistical information permits the processing of ensembles outside of focal attention, facilitating the rapid perception of visual scenes.
人们能够快速提取场景中常见模式或集合的总结统计信息，例如重复的纹理或颜色。在这里，我们使用一种方法来研究在没有焦点视觉注意的情况下这种集合感知是否会发生，该方法相对于之前用于研究该问题的方法具有一些优势。特别是，我们通过测量被忽略的集合对注意力集合的判断的间接影响，来评估在没有注意的情况下集合可以在多大程度上被处理。结果表明，当要忽略的集合包含与目标类别匹配的总结统计信息时，即使注意力集中在其他集合上，注意力之外的集合也会影响对注意力集合的判断。因此，特定总结统计信息的注意力控制设置允许处理焦点注意力之外的集合，从而促进视觉场景的快速感知。
