Abstract
Subjects were exposed to angular decelerations of between 1 and 50 deg/sec’ (1) in total darkness, (2) in view of a dim subject-stationary fixation light, or (3) inside an illuminated subject-stationary striped cylinder (conflict stimulation). Vestibularly induced eye movements led to the oculogyral illusion of object motion. This phenomenon can be distinguished from that of the sensation of self-rotation. At the end of deceleration, the initial velocity of self-rotation sensation is similar during all three stimulus conditions, but is reduced in duration with the conflict stimulus. Differences of interpretation in the literature concerning these phenomena can be explained on the basis of the failure to distinguish between the oculogyral illusion and sensation of self-motion and the inability to fully suppress vestibular eye movements.
