Under orthographic projection, biological motion point-light walkers offer no cues to the order of the dots in depth: Views from the front and from the back result in the very same stimulus. Yet observers show a bias toward seeing a walker facing the viewer (Vanrie, Dekeyser, & Verfaillie, 2004). Recently, we reported that this facing bias strongly depends on the gender of the walker (Brooks et al., 2008). The goal of the present study was, first, to examine the robustness of the effect by testing a much larger subject sample and, second, to investigate whether the effect depends on observer sex. Despite the fact that we found a significant effect of figure gender, we clearly failed to replicate the strong effect observed in the original study. We did, however, observe a significant interaction between figure gender and observer sex.
在正交投影下，生物运动的点光行走者没有提供关于深度上点的顺序的线索：从正面和背面看到的视图会产生完全相同的刺激。然而，观察者在看到行走者面对观察者时存在一种偏向（范里、德凯泽和韦尔法伊利，2004年）。最近，我们报告称这种朝向偏向很大程度上取决于行走者的性别（布鲁克斯等人，2008年）。本研究的目的，首先是通过测试一个大得多的受试者样本，来检验该效应的稳健性，其次是调查该效应是否取决于观察者的性别。尽管我们发现了人物性别的显著效应，但我们显然未能重复在原始研究中观察到的强烈效应。不过，我们确实观察到了人物性别与观察者性别之间的显著交互作用。
