Abstract: Abrupt scene changes are frequently encountered in movies, but how the processing of the novel scene influences subsequent viewing is not well understood. In this thesis, we conducted a series of experiments to investigate the phenomenon of rapid scene processing after a scene change. Previous studies have observed that initial saccades following a scene change were re-oriented to the scene?s center (e.g., Tatler, 2007), implying that the saccades were under the influence of the novel scene. However, we found that this was not necessarily so. Initial saccades could sometimes be under the influence of the previous scene. Further, initial saccades could be influenced by changes in the scene, as well as changes in the overall luminance of the scene. Our results also suggest a link between the re-orientation of initial saccades and the magnitude of scene change: initial saccades were more likely to be re-oriented to the center when the scene change is larger. Large scene changes (10?30%) increased the re-orienting of eye movements to the center; small scene changes (1%) did not, despite viewers? awareness of the change. Our results are discussed in relation to the rapid processing of novel scene information.
