In the research reported here, we found evidence of the cheerleader effect-people seem more attractive in a group than in isolation. We propose that this effect arises via an interplay of three cognitive phenomena: (a) The visual system automatically computes ensemble representations of faces presented in a group, (b) individual members of the group are biased toward this ensemble average, and (c) average faces are attractive. Taken together, these phenomena suggest that individual faces will seem more attractive when presented in a group because they will appear more similar to the average group face, which is more attractive than group members' individual faces. We tested this hypothesis in five experiments in which subjects rated the attractiveness of faces presented either alone or in a group with the same gender. Our results were consistent with the cheerleader effect.
在本研究报告中，我们发现了啦啦队效应的证据——人们在群体中比在独处时看起来更有吸引力。我们提出，这种效应是通过三种认知现象的相互作用产生的：（a）视觉系统自动计算群体中呈现的面孔的整体表现，（b）群体中的个体成员偏向于这种整体平均值，以及（c）平均面孔是有吸引力的。这些现象表明，当个体面孔出现在群体中时，它们会显得更有吸引力，因为它们会更类似于更有吸引力的平均群体面孔，而不是群体成员的个体面孔。我们在五个实验中测试了这个假设，实验中被试对单独呈现或与相同性别的群体一起呈现的面孔的吸引力进行了评分。我们的结果与啦啦队效应一致。
