Other Abstract

Human visual system is tuned to the motion of biological entities, which provides potentially vital information for survival. It has been demonstrated that observers can readily recognize the action, gender and identity information conveyed by pointed-light biological motion. However, more exploration should be spread into the mechanism of biological motion.

Our studies indicate:

Firstly, process and integration of multiple properties in biological motion Observers showed better direction discrimination when the walker walked at a fast pace which was not simply due to the difference of motion cycles. Also, observer's sex and walker's gender affected direction discrimination interactively. However, walking direction did not influence the gender perception.

Second, cross modality in biological motion. Olfaction provided information to perceive a walker's gender, moreover with a dissociate effect on observer's gender and sexual orientation, which suggested a cross-modality between olfactory and vision in biological motion perception.

Last, specificity of local motion and its influence on biological motion. Walking direction sensitivity could be enhanced by increasing the feet motion speed alone, so long as its direction was consistent with that of the other body parts. 'These findings highlighted the role of the fact in biological motion perception.
