A single, unique target often pops out quickly and efficiently from a field of homogenous distractors in visual search. Pop out has helped shape theories of visual attention and feature integration as well as to identify basic features in human vision. Here we report a new phenomenon, false pop out, wherein one of the homogenous distractors competes with the singleton target to pop out, perhaps by breaking an overall grouping or pattern emerging from the display. We show the effect occurs with more than 1 type of stimulus, and we discuss the implications of such a counterintuitive finding for theories of visual search.
在视觉搜索中，单一、独特的目标通常能迅速且高效地从一组同质干扰物中凸显出来。这种凸显现象有助于塑造视觉注意力和特征整合的理论，同时也有助于识别人类视觉中的基本特征。在此，我们报告一种新现象——错误凸显，即其中一个同质干扰物与单一目标竞争以凸显出来，这可能是通过打破显示屏中出现的整体分组或模式来实现的。我们表明这种效应在不止一种类型的刺激中都会出现，并且我们讨论了这一违反直觉的发现对视觉搜索理论的影响。
