Abstract
A large body of literature in reading indicates that “visual” information extracted from an eye fixation is not used to help encoding text on subsequent fixations. Moreover, similar experiments in object recognition and experiments in detecting changes in static scenes both indicate that little visual information is used even with non-symbolic stimuli. In contrast, experiments dealing with the perception of both simple rotary and complex biological motion indicate that quite accurate visual information must be maintained across fixations. This suggests that there may be a fundamentally different way in which motion and static information are retained and integrated across fixations.
