The information that is combined across fixations may be different for static and moving objects

A large body of literature in reading indicates that "visual" information e xtracted from an eye fixation is not used to help encoding text on subseque nt fixations. Moreover. similar experiments in object recognition and exper iments in detecting changes in static scenes both indicate that little visu al information is used even with non-symbolic stimuli. In contrast, experim ents dealing with the perception of both simple rotary and complex biologic al motion indicate that quite accurate visual information must be maintaine d across fixations. This suggests that there may be a fundamentally differe nt way in which motion and static information are retained and integrated a cross fixations.
