| Abstract: | Identification of a fixated object in a visual display is facilitated by integrating information from a preview of that object in the periphery with information extracted on the subsequent foveal fixation (A. Pollatsek et al; see record 1985-16415-001). These experiments investigated the extent to which this integration is dependent on the spatial location of the information remaining constant. Two preview objects were presented in the periphery; Ss fixated that region and named a single target object that appeared in the same spatial location in which one of the two preview objects had been presented. Of primary interest was the facilitative effect when a preview object was identical to the target object as a function of whether they were in the same spatial location. Although there was a small effect of switching, there was still a substantial preview benefit even when the location of the identical object switched. There was also a preview benefit in conditions in which there were no eye movements and the preview and target objects were at least 5° apart. The process of object identification may be relatively insensitive to location information. Object information and location information coded fairly independently.
