Pupil responses and optokinetic nystagmus (OKN) are known to vary with the brightness and direction of motion of attended stimuli, as well as gaze position. However, whether these processes are controlled by a common mechanism remains unclear. In this study, we investigated how OKN latency relates to pupil response latency under two conditions: gaze shifts (eye movement) and attention shifts (covert attention without eye movement). As a result, while OKN showed consistent temporal changes across both gaze and attention conditions, pupillary responses exhibited distinct patterns. Moreover, the results revealed no significant correlation between pupil latency and OKN latency in either condition. These findings suggest that, although OKN and pupillary responses are influenced by similar attentional processes, their underlying mechanisms may differ.
已知瞳孔反应和视动性眼震（OKN）会随着所关注刺激的亮度、运动方向以及注视位置而变化。然而，这些过程是否由共同机制控制仍不清楚。在本研究中，我们调查了在两种情况下OKN潜伏期与瞳孔反应潜伏期之间的关系：注视转移（眼球运动）和注意力转移（无眼球运动的隐蔽注意力）。结果显示，虽然OKN在注视和注意力两种情况下均呈现出一致的时间变化，但瞳孔反应表现出不同的模式。此外，结果表明在任何一种情况下，瞳孔潜伏期与OKN潜伏期之间均无显著相关性。这些发现表明，尽管OKN和瞳孔反应受相似的注意力过程影响，但其潜在机制可能不同。
