Shape-Independent Processing of Biological Motion

Show Summary Details

This chapter reviews evidence from numerous studies of inversion effects and preattentive processing that converge in suggesting that the visual system exploits its sensitivity to gravity-defined dynamics to detect the ballistic movements typical of limbed terrestrial animals in locomotion. It is proposed that a local visual filter may be sufficient to detect the gravity-defined dynamics of the most important types of animate motion. This local motion processing mechanism is thought to reflect both innate and learned component processes.

Keywords: biological motion; local motion; animate agency; inversion effects; animacy detection; gravitational acceleration; innate mechanisms; experience dependent mechanisms; periphery; attention
