Large-field visual motions induce postural sway. This postural sway contributes to stabilizing the posture in our everyday life. The purpose of this study was to investigate the spatio-temporal sensitivity of visually-induced postural sway. We presented a radial motion that was a simulation of observer's linear motion going through a cloud of dots. Heading direction was varied, and subject's postural sway was measured. In results, the direction of postural sway was qualitatively in the opposite direction to heading direction. This suggests that postural sway is basically consistent with heading direction. However, quantitatively the postural sway had an anisotropy between forward-backward axis and rightward-leftward axis: the sway in the latter axis was larger than in the former axis. Postural sway rapidly developed to 10% of maximum sway within 1-2[s], and gradually increased for 8-9[s]. This gradual development was characteristic of postural control in comparison with heading perception, which was very accurate with 500[ms] duration.
