ROLES OF OBJECT-FILE REVIEW AND TYPE PRIMING IN VISUAL IDENTIFICATIONWITHIN AND ACROSS EYE FIXATIONS

Dynamic visual identification was investigated in 4 experiments. In Ex periments 1 and 2, 2 perceptual objects (2 frames, each containing a l etter or 1 containing a letter and the other a plus sign) were preview ed in the periphery. A saccade brought these objects to central vision . During the saccade the display was changed so that 1 frame contained a letter and the other a plus sign, and the subject identified the le tter by naming it aloud as rapidly as possible. In Experiment 3, the r etinal events of Experiments 1 and 2 were simulated. In Experiment 4, both the preview and the target were presented centrally within a sing le fixation. In all experiments both object-specific and nonspecific p review benefits were observed. These results support a theory in which the preview benefits observed during visual identification arise from 2 processes, object file review and type priming.
