在三个实验中，目标和掩蔽刺激短暂闪烁，而观察者视觉跟踪一个移动的点。掩蔽刺激更有效时，他们似乎是在同一个地方的目标，但刺激视网膜的不同部分比当他们刺激视网膜的相同部分，但出现位移，因为干预追求眼球运动。因此，在追求眼球运动过程中的视觉掩蔽依赖于刺激的表观位置，而不是它们的视网膜位置，这与以前的研究不一致，在扫视眼球运动过程中的视觉掩蔽。这种明显的冲突可以用视觉掩蔽在跟踪和扫视运动中的功能意义来解释：扫视眼球运动后的视网膜位置掩蔽可能会擦除先前的图像，而追踪眼球运动期间的明显位置掩蔽可能会使移动目标更加可见。
In three experiments, targets and masking stimuli were briefly flashce while observers visually tracked a moving dot. Masking stimuli were more effective when they appeared to be in the same place as the target but stimulated different parts of the retina than when they stimulated the same parts of the retina but appeared displaced because of of an intervening pursuit eye movement. Visual masking during pursuit eye movements thus depended on the apparent position of the stimuli, not their retinal positions as such, which is in disagreement with previous studies of visual masking during saccadic eye movements. The apparent conflict can be explained in terms of the functional significance of visual masking in tracking and saccardic movements: Retinal position masking after saccadic eye movements may erase previous images, and apparent position masking during pursuit eye movements may make moving targets more visible.
