从历史上看，感知分组与物理原理相关。本文报道了一个新的发现，社会信息合作，而不是竞争关系，可以驱动感知分组的对象在动态追逐。特别地，每个关系都是用人类生成的追逐运动构建的（即，两个捕食者和一个猎物），和它的知觉分组的作用进行了检查分组引起的效应-注意的后果。结果表明：（1）由于捕食者之间的合作关系，捕食者被感知为一个群体，注意力在群体内自动扩散，从而促进了对目标出现在未被提示的捕食者身上的反应;（2）注意力对竞争性捕食者的影响与任何控制低水平运动模式的条件都没有区别，甚至包括不包含分组因素的随机运动条件。这些发现将知觉分组扩展到社会领域，这意味着社会信息在早期知觉阶段就参与了视觉认知。
Historically, perceptual grouping is associated with physical principles. This article reports a novel finding that social information—cooperative but not competitive relationships—can drive perceptual grouping of objects in dynamic chase. Particularly, each relationship was constructed with human-generated chasing motions (i.e., two predators and one prey), and its role on perceptual grouping was examined by grouping-induced effect—attentional consequences. The results showed that: (1) Predators can be perceived as a group due to their cooperative relationship, causing attention to automatically spread within grouped predators, thus the response to target appearing on uncued predator is also facilitated; and (2) The attentional effect on competitive predators has no difference from any condition which controls low-level motion patterns, even including the random-motion condition wherein no grouping factor was contained. These findings extend perceptualgrouping into the social field, implying that social information gets involved in visual cognition at an early perceptual stage.
