This study was conducted to examine the changes in body sway induced by presentation of slant 60° visual angle and upright visual stimuli. In the preliminary experiment, participants observed an X-axis line, a Y-axis line or a cross-in upright or slant presentations. Results showed no increase in body sway under any conditions. In the main experiment, perspective stimuli constructed of lines by which observers perceived an extent of space or non-perspective stimuli by which they perceived a plane surface were presented. Results indicated that body sway increased only when the perspective stimuli were shown in the slant presentation. The results suggested that only presentation of slant figures which participants perceived an extent of space affects postural equilibrium.
