关于目标运动的信息如何在眼球运动中体现的问题可以通过以下方式得到回答。之前被教导跟踪视觉目标的猴子，在目标开始移动后，会接触到速度以不同间隔瞬时变化的目标。扫视和平滑追踪眼球运动都可以通过目标运动的前 90 毫秒期间引入的目标速度的变化来改变。目标速度的变化可能会影响仅 50 毫秒后发生的眼跳的大小。扫视眼球运动的时间间隔短至 20 毫秒。这些结果表明，扫视和平滑追踪眼球运动都是基于连续处理的信息。
The question of how information concerning the motion of targets becomes manifested in eye movements was answered in the following way. Monkeys, previously taught to track visual targets, were exposed to targets whose velocity was instantaneously changed at varying intervals after the onset of target movement. Both saccadic and smooth pursuit eye movements could be altered by changes in target velocity introduced during the first 90 msec of target movement. A change in the velocity of the target could affect the size of a saccade occurring only 50 msec later. Saccadic eye movements occurred with intersaccadic intervals as short as 20 msec. These results indicate that both saccadic and smooth pursuit eye movements are based on continuously processed information.
