Previously, we have shown that discrete and continuous rapid aiming tasks are governed by distinct visuomotor control mechanisms by assessing the combined visual illusion effects on the perceived and effective index of difficulty (ID). All participants were perceptually biased by the combined visual illusion before they performed the rapid aiming tasks. In the current study, the authors manipulated the order of performing perceptual and motor tasks to examine whether perceptual or motor experience with the illusory visual target would influence the subsequent perceived and effective ID in discrete and continuous tapping tasks. The results supported our hypothesis showing that perceptual experience with the illusory visual target in the discrete condition reduced the effective ID in the subsequent discrete tapping task, and motor experience with the illusory visual target in the continuous condition reduced the illusion effects on the perceived ID in the subsequent perceptual judgment task. The study demonstrates the coinfluence of perception and action, and suggests that perception and action influence one another with different magnitude depending on the spatial frame of reference used to perform the perceptuomotor task.
此前，我们通过评估视觉错觉对感知难度指数（ID）和有效难度指数的综合影响，表明离散和连续快速瞄准任务受不同的视觉运动控制机制支配。在执行快速瞄准任务之前，所有参与者都受到了综合视觉错觉的感知偏差影响。在当前研究中，作者操纵了感知任务和运动任务的执行顺序，以检验对虚幻视觉目标的感知或运动体验是否会影响后续离散和连续敲击任务中的感知难度指数和有效难度指数。结果支持了我们的假设，即离散条件下对虚幻视觉目标的感知体验降低了后续离散敲击任务中的有效难度指数，而连续条件下对虚幻视觉目标的运动体验降低了后续感知判断任务中错觉对感知难度指数的影响。该研究证明了感知与行动的相互影响，并表明感知和行动根据用于执行感知运动任务的空间参照系以不同程度相互影响。
