| Abstract: | Six experiments are reported dealing with the types of information integrated across eye movements (EMs) in picture perception. A line drawing of an object was presented in peripheral vision, and the 12 Ss (members of the university community) made an EM to it. During the saccade, the initially presented picture was replaced by another that the S was instructed to name as quickly as possible. The relation between the stimulus on the 1st fixation and the stimulus on the 2nd fixation was varied. Across experiments, there was about 100–230 msec facilitation when the pictures were identical compared with a control condition in which only the target location was specified on the 1st fixation. This finding implies that information about the 1st picture facilitated naming the 2nd picture. When the pictures represented the same concept (e.g., 2 pictures of a horse), there was a 90-msec facilitation effect that could have been the result of either the visual or conceptual similarity of the pictures. However, when the pictures had different names, only visual similarity produced facilitation; there appeared to be inhibition from the competing names. Results of all experiments are consistent with a model in which the activation of both the visual features and the name of the picture seen on the 1st fixation survive the saccade and combine with the information extracted on the 2nd fixation to produce identification and naming of the 2nd picture.
