During a saccade, the image of the environment moves rapidly across the retina. However, due to saccadic suppression, our perception of motion is attenuated and our visual sensitivity is suppressed. We explored whether the extent of saccadic suppression depends on the type of image transformation. Participants observed three-dimensional scenes and made a vertical or horizontal saccade to follow a target object. During this saccade, the entire scene was translated or rotated along one of the canonical directions. After each trial, participants indicated the direction of the scene change in a forced-choice task. Change detectability depended on the magnitude and type of transformation. During vertical or horizontal saccades, users were least sensitive to vertical or horizontal translations, respectively, and most sensitive to rotations along the roll axis. We conclude that saccadic suppression affects natural image transformations that occur during whole body and head movement through our environment.
