Much evidence suggests that visual motion can cause severe distortions in the perception of spatial position. In this study, we show that visual motion also distorts saccadic eye movements. Landing positions of saccades performed to objects presented in the vicinity of visual motion were biased in the direction of motion. The targeting errors for both saccades and perceptual reports were maximum during motion onset and were of very similar magnitude under the two conditions. These results suggest that visual motion affects a representation of spatial position, or spatial map, in a similar fashion for visuomotor action as for perception.
大量证据表明，视觉运动可导致空间位置感知出现严重扭曲。在本研究中，我们表明视觉运动也会扭曲扫视眼动。对视觉运动附近呈现的物体进行扫视的着陆位置在运动方向上存在偏差。扫视和感知报告的目标误差在运动开始时最大，并且在两种情况下大小非常相似。这些结果表明，视觉运动以类似的方式影响空间位置的表征或空间地图，无论是对于视觉运动动作还是对于感知。
