A number of experiments were conducted to determine to what extent retinal image smearing during saccades provides information about the eye movement magnitude to the perceptual system. The technique involved obtaining measures of perceived movement when the total visual field was displaced in conjunction with saccadic eye movements. Trials with normal retinal smear were compared with trials on which smearing was greatly reduced or eliminated. The results are interpreted as showing that the absence of normal retinal smear during a saccade increases the uncertainty in the information available to the perceptual system and that this uncertainty results in a tendency to perceive smaller than veridical amounts of movement.
进行了多项实验，以确定扫视过程中视网膜图像模糊在多大程度上向感知系统提供有关眼球运动幅度的信息。该技术涉及在整个视野与眼球扫视运动一起移动时获取感知运动的测量值。将具有正常视网膜模糊的试验与视网膜模糊大大减少或消除的试验进行比较。结果被解释为表明扫视过程中正常视网膜模糊的缺失增加了感知系统可获得信息的不确定性，并且这种不确定性导致感知到的运动量小于实际运动量的倾向。
