A Bayesian Model of Perceived Head-Centered Velocity during Smooth Pursuit Eye Movement
During smooth pursuit eye movement, observers often misperceive velocity. Pursued stimuli appear slower (Aubert-Fleishl phenomenon [1, 2]), stationary objects appear to move (Filehne illusion [3]), the perceived direction of moving objects is distorted (trajectory misperception [4]), and self-motion veers away from its true path (e.g., the slalom illusion [5]). Each illusion demonstrates that e...
متن کاملCompensation for equiluminant color motion during smooth pursuit eye movement.
Motion perception is compromised at equiluminance. Because previous investigations have been primarily carried out under fixation conditions, it remains unknown whether and how equiluminant color motion comes into play in the velocity compensation for retinal image motion due to smooth pursuit eye movement. We measured the retinal image velocity required to reach subjective stationarity for a h...
متن کاملDirection and extent of perceived motion smear during pursuit eye movement
Smooth pursuit eye movements superimpose additional motion on the retinal image of untracked visual targets, potentially leading to the perception of motion smear and a distortion of the perceived direction of motion. Previously, we demonstrated an attenuation of perceived motion smear when the untracked target moves in the opposite direction of an ongoing pursuit eye movement. In this study, t...
متن کاملSpeed Discrimination of Distal Stimuli during Smooth Pursuit Eye Motion
We evaluated the hypothesis that smooth pursuit eye movements affect speed discrimination thresholds of distal stimuli because they alter the retinal image speed. Subjects judged speed differences of sine-wave gratings while they simultaneously pursued a superimposed moving bar. Speed discrimination thresholds were measured, under conditions of controlled eye movements, for grating speeds of 0....
متن کاملSuppression of motion-produced smear during smooth pursuit eye movements
Humans make smooth tracking eye movements to keep the image of a moving target on the foveal region of the retina and, thereby, maintain acute vision. Although the images of physically stationary background stimuli sweep across the retina during smooth pursuit eye movements, non-pursued targets are usually perceived to be neither moving nor smeared. The lack of perceived movement of background ...
