When two visual patterns moving in opposite directions are superimposed on the same depth plane, they appear to have two transparent surfaces moving independently (transparent motion). Additionally, the direction of the slow phase of optokinetic nystagmus (OKN) corresponds to the direction of motion that dominates the perceptual appearance. This study examines whether pupil changes correspond to the luminance of the dominated objects related to the transition of the slow-phase direction in OKN following objects. Stimuli consisted of two random dot patterns of different luminance that moved in opposite directions. The results showed that pupil size changed in accordance with the luminance of the pattern in the slow phase of OKN immediately after OKN transition. This suggests that pupil size is modulated with OKN in transparent motion.

瞳孔反应由透明运动中的视动眼球震颤调节
当两个方向相反的视觉图案叠加在同一深度平面上时,它们看起来有两个独立移动的透明表面(透明运动)。此外,视动性眼球震颤 (OKN) 的慢相方向对应于支配感知外观的运动方向。本研究检查瞳孔变化是否对应于与 OKN 跟随物体中慢相方向转变相关的主导物体的亮度。刺激由两个不同亮度的随机点图案组成,它们向相反的方向移动。结果表明,在OKN过渡后,瞳孔大小随OKN慢相中图案的亮度而变化。这表明瞳孔大小是在透明运动中用 OKN 调制的。
