Abstract
Investigating the effects of stimulus frequency on tilt and translation motion perception during constant velocity off-vertical axis rotation (OVAR), the findings were compared to those of stimulus frequency's effects on eye movements. Dynamic linear acceleration alters the amount of both self-motion perception and eye movements in the absence of any sensory data (from the canal or vision). Contrary to eye movements, the phase of perceived tilt and translation motion is unaffected by stimulus frequency. The finding that distinguishing tilt and translation linear acceleration stimuli requires distinct brain processing from eye motions and motion perception
