Predictions made for Experiments 1 ([https://osf.io/bhrt5/][1]) and 2 ([https://osf.io/vgbnq/][2]) remain our working hypotheses. We further predict: 1. Perceived amount of smear (indicated by motion filter length) will increase with presentation duration, as long as presentation offsets occur prior to saccade offset. As presentation offsets approach or exceed saccade offsets, post-saccadic masking should occur, reducing the perceived amount of smear. 2. Whereas in previous experiments colored images (compared to grayscale images) elicited enhanced scene matching performance - most likely simply because more information to solve the task was available - it is unlikely that, using a subjective measure, grayscale images should elicit a larger amount of perceived smear than color images. 3. We expect that there will be different masking time courses for full-field and aperture scenes. Specifically, we expect more efficient masking (i.e., a faster reduction of motion-filter length as presentation offsets fall in the post-saccadic interval) for full-field than for aperture stimuli. Following this hypothesis, we also expect steeper masking time courses at larger aperture SDs. 4. We predict that the perceived direction of motion smear will be directly related to the inducing saccade's direction. While overall accurate (as the direction judgment could also be influenced by extra-retinal signals), the precision with which the angle is reported by observers will decrease with increasing presentation durations, and presentation offsets after saccade offset, due to masking. 5. We predict that the length of the adjusted motion filter will be strongly correlated with the distance that the eye travels while the screen is illuminated. This relationship is expected to be stronger for aperture stimuli (especially those with smaller SDs), as those could produce more distinctive motion streaks.
