This study compared the latencies of visually induced postural change and self-motion perception under identical visual conditions. The results showed that a visual roll stimulus elicits postural tilt in the direction of scene motion and an increase in postural instability several seconds before the subject begins to perceive illusory self-motion (vection) in the opposite direction. Postural and vection latencies correlate highly with one another, but bear little relationship with the magnitude of either sway or vection.
本研究在相同视觉条件下比较了视觉诱发的姿势变化潜伏期和自我运动感知潜伏期。结果表明，在受试者开始感知到相反方向的虚幻自我运动（运动错觉）前几秒，视觉横滚刺激会引发姿势向场景运动方向倾斜以及姿势不稳定性增加。姿势潜伏期和运动错觉潜伏期高度相关，但与摇摆或运动错觉的幅度关系不大。
