This study investigated the effect of information within visual fields on postural control. Thirty-six undergraduate and graduate students participated in the experiment. The body sway was measured while participants watched static visual stimuli presented in the central visual field, the peripheral visual field, and the full visual field. Squares that differed in sizes were used as stimuli to provide similar visual information in each visual field. The result showed that body sway was reduced when the stimulus was presented in the peripheral visual field relative to when it was presented in the central visual field. This result suggests that information of the peripheral visual field may play an important role in postural control.
