电视技术的发展使得研究视觉反馈在运动控制中的作用的新方法成为可能。在使用特殊视盘记录和回放系统的两项实验中，研究了在目标定向运动期间受试者看到自己的手延迟 66 毫秒的影响。与棱镜产生的空间扭曲反馈相比，观察到的这种视觉延迟反馈的效果得出了三个主要结论：（a）尽管两种改变的反馈引起了行为相似性（过调），但每种反馈在视觉运动控制环路中的作用是不同的； (b) 对两种改变的反馈的适应和后效是基于不同的控制机制。 (c) 手部控制中视觉信息的处理和使用所需的时间比以前的实验表明的要少。
Developments in television technology have made possible new approaches to the study of the role of visual feedback in motor control. In two experiments using a special videodisc recording and playback system, the effects of delaying for 66 msec a subject's view of his own hand during a target-directed movement was investigated. The observed effects of such visually delayed feedback compared to spatially distorted feedback produced by prisms led to three major conclusions: (a) despite the behavioral similarity (overshooting) induced by the two kinds of altered feedback, the role of each in the visual-motor control loop is different; (b) adaptation to and the after effect of the two kinds of altered feedback are based on different control mechanisms (c) the processing and use of visual information in hand control requires less time than previous experiments have indicated.
