几个时间和空间因素影响性别识别的步行者描绘时，没有熟悉的线索，作为一个动态的点光显示。在时间参数中，动态刺激的持续时间必须长于1.6 s，但2.7 s是完全足够的。考虑到步行者的速度，识别阈值似乎大致为2步周期。刺激的呈现速率必须接近正常，这可能是因为非正常速率改变了表观重力，模糊了输出和能量守恒之间的正常关系。在空间因素中，为了准确识别，必须保持关节信息的离散性。显然，有关步行者肩部和臀部的信息才是最重要的。刺激显示的颠倒产生了意想不到的效果，即颠倒了大多数步行者的明显性别。当颠倒呈现时，男性步行者看起来像女性，女性步行者看起来像男性。
Several temporal and spatial factors affect gender recognition of a walker when portrayed, without familiarity cues, as a dynamic point-light display. Among temporal parameters, the duration of the dynamic stimulus must be longer than 1.6 s, but that 2.7 s is fully adequate. Given the speed of walkers, the recognition threshold appears to be roughly 2 step cycles. Presentation rate of the stimulus must be near to normal, perhaps because nonnormal rates alter apparent gravity and obscure the normal relationship between output and conservation of energy. Among spatial factors, the discreteness of the joint information must be maintained for accurate recognition. It is apparently the information about the shoulder and the hip of a walker that is of primary importance. Inversion of the stimulus display produces the unexpected effect of reversing the apparent sex of most walkers. When presented upside down, male walkers appear female and female walkers appear male.
