The analysis of eye movements during motor imagery has been used to understand the influence of covert motor processes on visual-perceptual activity. There is evidence showing that gaze metrics seem to be affected by motor planning often dependent on the spatial and temporal characteristics of a task. However, previous research has focused on simulated actions toward static targets with limited empirical evidence of how eye movements change in more dynamic environments. The study examined the characteristics of eye movements during motor imagery for an interception task. Twenty-four participants were asked to track a moving target over a computer display and either mentally simulate an interception or rest. The results showed that smooth pursuit variables, such as duration and gain, were lower during motor imagery when compared to passive observation. These findings indicate that motor plans integrate visual-perceptual information based on task demands and that eye movements during imagery reflect such constraint.
对运动想象过程中眼动的分析已被用于理解隐蔽运动过程对视觉感知活动的影响。有证据表明，注视指标似乎常受运动计划的影响，而运动计划往往取决于任务的时空特征。然而，以往的研究主要集中在对静态目标的模拟动作上，关于在更动态的环境中眼动如何变化的实证证据有限。该研究考察了拦截任务的运动想象过程中眼动的特征。24名参与者被要求在电脑显示屏上追踪一个移动目标，并在心里模拟拦截或休息。结果表明，与被动观察相比，运动想象过程中的平滑追踪变量，如持续时间和增益，较低。这些发现表明，运动计划根据任务需求整合视觉感知信息，且想象过程中的眼动反映了这种限制。
