Transsaccadic memory and integration during real-world object perception

What is the nature of the information that is preserved and combined across saccadic eye movements during the visual analysis of real-world objects? The two experiments reported investigated transsaccadic memory and transsaccadic integration, respectively. In the critical condition, participants were presented with one set of contours from an object during one fixation and with a complementary set of contours during the next fixation. In Experiment 1, participants could at best inconsistently detect contour changes across the saccade. In Experiment 2, a change in visible contour had no influence on object identification. These results suggest that a veridical representation of object contour is neither consistently preserved nor integrated across a saccade.
