Abstract
The beginning of a saccade triggers a step in target position, and then the target is extinguished 1–300 msec later. A primary saccade follows with normal accuracy, and approximately normal latency. A corrective saccade to the invisible target is possible if the target is lit during the early part of the prior primary saccade. Clearly, important visual stimulation can occur during saccades, and the interaction of retinal and eye position information is such that saccades are goal-directed. The only finding reminiscent of perceptual “saccadic suppression” and mislocation effects is that a target which steps to a position ahead of a saccade is sometimes ignored.
