The motor-cognitive model proposes that movement imagery additionally requires conscious monitoring owing to an absence of veridical online sensory feedback. Therefore, it is predicted that there would be a comparatively limited ability for individuals to update or correct movement imagery as they could within execution. To investigate, participants executed and imagined target-directed aiming movements featuring either an unexpected target perturbation (Exp. 1) or removal of visual sensory feedback (Exp. 2). The results of both experiments indicated that the time-course of executed and imagined movements was equally influenced by each of these online visual manipulations. Thus, contrary to some of the tenets of the motor-cognitive model, movement imagery holds the capacity to interpolate online corrections despite the absence of veridical sensory feedback. The further theoretical implications of these findings are discussed.
运动认知模型提出，由于缺乏真实的在线感觉反馈，运动想象额外需要有意识的监控。因此，预计个体在运动想象中更新或纠正运动的能力相对有限，因为他们可以在执行过程中进行。为了研究这一点，参与者执行和想象了具有以下两种特征的目标导向瞄准运动：（实验 1）出现意外目标干扰，或（实验 2）视觉感觉反馈被移除。这两个实验的结果都表明，执行和想象运动的时间进程都受到这两种在线视觉操作的同样影响。因此，与运动认知模型的某些原则相反，运动想象尽管缺乏真实的感觉反馈，但仍具有在线纠正的能力。讨论了这些发现的进一步理论意义。
