Gender Discrimination in Biological Motion Displays Based on Dynamic Cues

摘要: Studies of human locomotion have found that male and female walkers differ in terms lateral body sway, with males tending to swing their shoulders from side more than hips, females hips shoulders. Experiments reported here demonstrate naive viewers can identify the gender figure a biological motion display very reliably when contains gender-specific sway. Sensitivity is high even for displays containing only fraction step cycle. This dynamic cue dominates structural cues based on torso shape (`centre-of-moment9) are set opposition. It mediated by differences velocity shoulder hip dots, not positional dots during
