In two different experiments, subjects reported on the visual direction of a flash presented during a voluntary saccade relative to the visual direction of a stimulus viewed prior to the saccade. Under the conditions of the first experiment the report given by the subject was primarily determined by the relative retinal positions of the two stimuli. In the second experiment evidence was obtained for precisely timed shifts in local signs which are due to proprioceptive compensation for changes in ocular position during the saccade.
