ABSTRACT
It is a common observation that the visual world remains phenomenally clear and stable in spite of the frequent and rapid saccadic eye movements that we make in looking from one object to another in the visual field. Visual perception seems to extend continuously through long intervals of time, even though a complete relocation of the visual field must take place every time we make a saccade. The stability and clarity of the scene in the face of retinal image motion during sacca des is to be distinguished from the related problem of stability in the face of changes in position on the retina, or local sign, of images which are viewed in the successive fixational pauses between saccades. These two aspects of phenomenal stability mayor may not be accomplished by the same mechanisms. This question will be discussed below by Dr. Ethel Matin, and later on by the contributors to Part N.
