Synthetic versions of human walkers were generated by computer as point-light displays. Previously it had been determined that the natural gaits of males and females differ according to the extent of movement at the shoulder and the hip. These movements were measured and then used to synthesize the stimuli used in the present study. These stimuli are shown here to be identified by untrained viewers as male when the shoulder movement is greater than the hip movement, and female when the configuration is reversed. Because of the coherence of the display lights representing the shoulder and hip are not necessary for gender recognition, although they do increase performance level. Hypernormality and heavy-footedness in gait are also discussed. Finally, all results are linked to an underlying biomechanical invariant, the center of moment.
人类行走者的合成版本由计算机生成为点光显示。此前已经确定，男性和女性的自然步态根据肩部和臀部的运动程度而有所不同。测量了这些运动，然后用于合成本研究中使用的刺激。这里显示，当肩部运动大于臀部运动时，未经训练的观察者将这些刺激识别为男性，而当配置相反时则识别为女性。由于代表肩部和臀部的显示灯的连贯性对于性别识别不是必需的，尽管它们确实会提高表现水平。还讨论了步态中的超常态和沉重感。最后，所有结果都与一个潜在的生物力学不变量——力矩中心相关联。
