It has recently been shown that perceived motion, in the absence of any appropriate retinal motion, is a sufficient stimulus to generate smooth pursuit eye motions. This raises the question of whether perceived motion is necessary for pursuit. In three experiments we obtained a negative answer to this question: retinal motion always governed pursui...

The normal relation between retinal image displacement and saccadic eye movement was experimentally altered by moving a stimulus vertically up or down contingent upon a subject's horizontal saccades. For half the subjects the stimulus moved up with a rightward and down with a leftward saccade, while for the other subjects the reverse was the case....

... al targets at the time of a saccade in order to assess whether peri-saccadic compression of space (systematic mislocalization of visual targets toward the saccade target ) was focussed around the intended saccade target or the actual saccade endpoint. Their results showed that the focus of compression shifts with adaptation, to the actual endpoint. Mack, Fendrich, and Pleune (1978) showed that the threshold for detecting the direction of motion of a visual target was aVected by adaptation. When horizontal saccades were adapted to acquire a vertical component, the detection threshold increased for motion in the direction of the amplitude shift and decreased for opposite motion. A study using a discrimination task s ...
... Contrary to the studies mentioned so far, several studies have suggested that visual motion signals are dissociated from perception and pursuit eye movements (Barton, Sharpe, & Raymond, 1996;Gegenfurtner, Xing, Scott, & Hawken, 2003;Hawken & Gegenfurtner, 2001;Mack, Fendrich, & Pleune, 1979;Spering & Carrasco, 2012;Spering & Gegenfurtner, 2007;Spering, Pomplun, & Carrasco, 2011;Tavassoli & Ringach, 2010; for reviews, see Spering & Carrasco, 2015). Other studies have suggested dissociations between motion perception and ocular following response for the same visual motion information (Bostrom & Warzecha, 2010;Glasser & Tadin, 2014;Simoncini, Perrinet, Montagnini, Mamassian, & Masson, 2012; for reviews, see Spering & Carrasco, 2015). ...
