Abstract
During saccadic eye movements, images of external objects move rapidly across the retina. Small, unpredictable displacements imposed upon a target moving at saccadic velocity were detected with equal accuracy when (1) the retinal image velocity was caused by an eye movement, or (2) when the same velocity was produced during fixation (simulated saccadic conditions). The results provide no evidence of a specific non-visual suppression of vision during saccades, nor of any other compensatory modification of afferent visual inflow which might contribute to our sense of directional stability during saccades.
