Abstract

During normal vision the world is continuously scanned by a sequence of saccadic eye movements that shift the direction of gaze from two to six times each second. When viewing a stationary field, perceptual information is derived from the retinal images formed during fixational pauses. Eye position during fixation determines the portion of the visual scene that is available for processing and the duration of each fixation defines the time required for processing that information before the next saccade. Thus, the recording of eye movements provides an objective behavioral index of visual processing. Since visual scanning behavior is observed in the alert human subject from birth, oculomotor behavior provides a unique index of visual processing that can be observed throughout life.
