Grouping operations offer an effective mechanism by which to structure complex visual scenes. Among the various principles that support element integration, closure may be regarded as a main factor in shape extraction. In five experiments, we investigated the impact of grouping by closure on search for target configurations made up of collinearly arranged corner junctions. Systematic variations in the configuration of distractor elements were explored to investigate how the figural information of distractors interferes with target detection. The results showed no search interference for distractor configurations that were open forms. By contrast, distractors making up closed forms reduced the efficiency of search performance, indicating closure as a major contributor to form detection in multielement configurations. In conclusion, the effects reported may be considered to arise from mechanisms of unit formation that support the rapid extraction of salient regions to guide search.
分组操作提供了一种构建复杂视觉场景的有效机制。在支持元素整合的各种原则中，封闭性可被视为形状提取的一个主要因素。在五项实验中，我们研究了通过封闭性进行分组对搜索由共线排列的角连接组成的目标构型的影响。我们探索了干扰元素构型的系统变化，以研究干扰物的图形信息如何干扰目标检测。结果表明，对于开放形式的干扰物构型没有搜索干扰。相比之下，构成封闭形式的干扰物降低了搜索性能的效率，这表明封闭性是多元素构型中形状检测的主要因素。总之，所报告的这些效应可能被认为是由支持快速提取显著区域以指导搜索的单元形成机制引起的。
