During a pursuit eye movement made across a stationary stimulus, that stimulus is often perceived as moving slightly in the direction opposite to the eyes (Filehne illusion). The illusion is generally thought to increase in strength when the stimulus is made visible only briefly. In two experiments the illusion was indeed observed with young subjects. However, with older subjects brief stimulus presentations yielded a strong inverted Filehne illusion (the stimulus appeared to move in the same direction as the eyes). This age dependency of the Filehne illusion is caused by an increase of only the threshold for stimulus motion in the direction opposite to the eyes. No such effect happens with the threshold for stimulus motion in the same direction as the eyes. These findings can be explained if we assume that with increasing age it takes more time to properly register retinal image velocity within the perceptual system.
在对静止刺激进行追踪眼动期间，该刺激通常会被感知为朝着与眼睛相反的方向轻微移动（费尔内错觉）。一般认为，当刺激仅短暂可见时，这种错觉的强度会增加。在两项实验中，确实在年轻受试者身上观察到了这种错觉。然而，对于年长受试者，短暂呈现刺激会产生强烈的反向费尔内错觉（刺激似乎朝着与眼睛相同的方向移动）。费尔内错觉的这种年龄依赖性是由仅与眼睛相反方向的刺激运动阈值增加所导致的。与眼睛相同方向的刺激运动阈值则没有这种效应。如果我们假设随着年龄增长，在感知系统中正确记录视网膜图像速度需要更多时间，那么这些发现就可以得到解释。
