***Predictions*** 1. Due to increased stimulus contrast, longer movement distance and duration, we expect task performance to be higher than in preceding experiments and significantly above chance. 2. Localization performance will be better, the lower the spatial frequency of the applied stimulus: d'(SF=0.5) > d'(SF=1) > d'(SF=2). 3. Gabor orientation relative to the retinal trajectory of the Gabor (resulting from eye movement and stimulus movement) can be described in four factor levels: horizontal, vertical, orthogonal, and parallel. We predict that gratings parallel to their retinal movement trajectory will be discriminated best and orthogonal orientations worst, as they should lead to more conspicuous motion streaks (Alais et al., 2011). 4. Correct responses will have shorter reaction times. **References** Alais, D., Apthorp, D., Karmann, A., Cass, J. (2011).
