註釋

The world is perceived to be stable, even though we move our eyes. Perceived stability is disrupted, however, if the eye is moved passively by gently pressing on one with a Finger. The present series of studies explores the nature of perceptual stability during saccades, the kind of eye movement made when looking from one object to another. Saccades are high velocity eye movements; they are highly stereotypic and usually last less than 100 msec. They are interesting because they might be expected to disrupt perceptual stability, yet they do not. The first study deals with changes in perceived direction associated with saccades. There are two theories concerning the role of a centrally originating corollary discharge in readjusting perceived direction. One theory states that perceived direction is readjusted continuously and slowly, while the other states that the readjustment is discrete and abrupt.
