The relationship among baseline pupil size, fixation stability, and inhibitory control were examined in this study. Participants performed a baseline eye measure in which they were instructed to stare at a fixation dot on screen for 2 min. Following the baseline eye measure, participants completed an antisaccade task to measure inhibitory control ability. We found a correlation between baseline pupil size variability and inhibitory control, as well as between fixation stability and inhibitory control. We showed that participants with better inhibitory control exhibited larger variability in pupil size, and those with better fixation stability showed superior inhibitory control ability. Overall, our results indicate that there are significant correlations between inhibitory control and baseline pupil size, as well as between inhibitory control and fixation stability.
本研究考察了基线瞳孔大小、注视稳定性和抑制控制之间的关系。参与者进行了基线眼动测量，他们被指示在屏幕上的注视点注视 2 分钟。在基线眼动测量之后，参与者完成了反扫视任务以测量抑制控制能力。我们发现基线瞳孔大小变异性与抑制控制之间以及注视稳定性与抑制控制之间存在相关性。我们表明，抑制控制能力更好的参与者表现出更大的瞳孔大小变异性，而注视稳定性更好的参与者表现出更高的抑制控制能力。总体而言，我们的结果表明抑制控制与基线瞳孔大小之间以及抑制控制与注视稳定性之间存在显著相关性。
