Psychophysical approach to effects of active observation on the temporal aspects of visual information processing

我们进行了心理物理实验，以了解观察者对刺激变化的主动控制如何影响视觉感知的时间方面。当观察者使用计算机鼠标控制刺激运动时，我们发现，随着手部运动和刺激运动之间特定的方向关系的学习，或者它们之间的方向一致，时空错觉显著减少。我们的结果表明，主动手部运动的本体感觉信号有助于对伴随着主动手部运动的视觉刺激的视觉加工。

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.
