Previous research has investigated the degree of congruency in gaze metrics between action execution (AE) and motor imagery (MI) for similar manual tasks. Although eye movement dynamics seem to be limited to relatively simple actions toward static objects, there is little evidence of how gaze parameters change during imagery as a function of more dynamic spatial and temporal task demands. This study examined the similarities and differences in eye movements during AE and MI for an interception task. Twenty-four students were asked to either mentally simulate or physically intercept a moving target on a computer display. Smooth pursuit, saccades, and response time were compared between the two conditions. The results show that MI was characterized by higher smooth pursuit gain and duration while no meaningful differences were found in the other parameters. The findings indicate that eye movements during imagery are not simply a duplicate of what happens during actual performance. Instead, eye movements appear to vary as a function of the interaction between visuomotor control strategies and task demands.
先前的研究已经调查了在执行动作 (AE) 和运动想象 (MI) 时，相似手动任务之间注视指标的一致性程度。虽然眼动动力学似乎仅限于针对静态物体的相对简单的动作，但很少有证据表明在想象中，注视参数如何随着更动态的空间和时间任务需求而变化。本研究考察了在执行动作和想象期间，眼动在拦截任务中的异同。要求二十四名学生在计算机显示器上进行精神模拟或物理拦截移动目标。在两种情况下比较了平滑追踪、扫视和反应时间。结果表明，MI 的特点是平滑追踪增益和持续时间更高，而其他参数则没有明显差异。研究结果表明，想象过程中的眼动并不是实际执行过程的简单复制。相反，眼动似乎随着视觉运动控制策略和任务需求之间的相互作用而变化。
