许多视觉感知理论假设，在注意力被分配到场景之前，视觉信息是根据完形组织原则进行解析的。这一假设受到了实验的挑战，在实验中，参与者无法识别在主要任务显示的背景下发生的完形分组模式（A。麦克，B。唐河，巴西-地图马岛Kahn，& I. Rock，1992）。在本研究中，参与者报告了两条水平线中哪一条更长。背景中的点，如果分组，形成类似于庞佐错觉（实验1和2）或穆勒-莱尔错觉（实验3）的显示。尽管对这些模式的报道并不准确，但参与者在线条长度辨别任务中的反应明显受到这两种错觉的影响。这些结果表明，在没有注意力的情况下，完形分组确实会发生，但这样形成的模式可能不会在没有注意力的情况下编码在记忆中。
Many theories of visual perception assume that before attention is allocated within a scene, visual information is parsed according to the Gestalt principles of organization. This assumption has been challenged by experiments in which participants were unable to identify what Gestalt grouping patterns had occurred in the background of primary-task displays (A. Mack, B. Tang, R. Tuma, S. Kahn, & I. Rock, 1992). In the present study, participants reported which of 2 horizontal lines was longer. Dots in the background, if grouped, formed displays similar to the Ponzo illusion (Experiments 1 and 2) or the Muller-Lyer illusion (Experiment 3). Despite inaccurate reports of what the patterns were, participants' responses on the line-length discrimination task were clearly affected by the 2 illusions. These results suggest that Gestalt grouping does occur without attention but that the patterns thus formed may not be encoded in memory without attention.
