This article illustrates a dissociation between the perceived attributes of an object and the ability of those attributes to guide the deployment of attention in visual search. Orientation is an attribute that guides search. Thus, a vertical line will "pop out" amid horizontal distractors. Amodal completion can create perceptually convincing oriented stimuli when two elements appear to form a complete object partially hidden behind an occluder. Previous work (e.g., Rensink & Enns, Vision Research, 38, 2489-2505, 1998) has shown a preattentive role for amodal completion in search tasks. Here, we show that orientation based on perceptually compelling amodal completion may fail to guide attention. The broader conclusion is that introspection is a poor guide to the capabilities of our internal search engine.
本文阐述了物体的感知属性与这些属性在视觉搜索中引导注意力分配能力之间的分离。方向是一种引导搜索的属性。因此，一条垂直线会在水平干扰物中“突显出来”。当两个元素似乎形成一个部分隐藏在遮挡物后面的完整物体时，非模态完成可以创建在感知上令人信服的有方向的刺激。先前的研究（例如，Rensink和Enns，《视觉研究》，第38卷，第2489 - 2505页，1998年）已经表明非模态完成在搜索任务中具有前注意作用。在这里，我们表明基于感知上令人信服的非模态完成的方向可能无法引导注意力。更广泛的结论是，内省对于我们内部搜索引擎的能力而言是一个不可靠的指导。
