摘要
Two-dimensional eye movements were recorded while observers used ballistic arm movements to localize targets presented during smooth pursuit. Mean position of responses was 2′ arc (SE = 3′ arc) from a target when localizations depended solely on eye position. Next, observers accurately struck an untracked target seen moving in the peripheral retina showing that eye position cues were used to compensate for retinal image motion caused by pursuit of other objects. Finally, observers used the method of adjustment to veridically set the path of a target to show that accurate localizations were not restricted to a motor task. These results show that observers are sensitive to changes in the position of the pursuing eye. © 1979.
