| Research Abstract |
We conducted psychophysical experiments to understand how observers' active control of stimulus change affects temporal aspects of visual perception. When observers controlled the stimulus movement by the use of a computer mouse, we found a significant reduction of the spatio-temporal illusions, with the learning of a specific directional relationship between hand movements and stimulus movements, or with directional consistency between them. Our results suggest that the proprioceptive signal of active hand movement would facilitate the visual processing for the concomitant visual stimulus, which is concomitant to the active hand movement.
