Abstract

It is well known that vision makes an important contribution to the control of goal-directed movements. However, task performance can be maintained when vision is interrupted, such as when a goalkeeper faces a free kick in soccer and the ball moves behind teammates and opposing players. To maintain behavior, it is necessary to process the visual information available from intermittent samples. In this review, we consider the performance and learning effects of intermittent vision in tasks such as aiming, reaching and grasping, goal-directed locomotion and ball-catching. We review research that finds both interocular and intraocular integration contribute to continuous upper limb control with intermittent visual pickup/sampling. Recent work using intermittent visual presentation (i.e., stroboscopic vision) to facilitate learning of general and task-specific visual-motor skills indicates that training/learning protocols that challenge, but don’t alter, the visual-motor processing associated with a specific visual-motor task can be effective. In this theoretical context, we discuss methodological and design factors that could impact the effectiveness of future training studies.

摘要

众所周知，视觉对目标导向运动的控制做出了重要贡献。但是，当视线被打断时，任务性能可以保持不变，例如当守门员在足球比赛中面对任意球并且球在队友和对方球员身后移动时。为了保持行为，有必要处理间歇样本中可用的视觉信息。在这篇综述中，我们考虑了间歇性视觉在瞄准、伸手和抓握、目标导向运动和接球等任务中的表现和学习效果。我们回顾了研究发现眼间和眼内整合有助于通过间歇性视觉拾取/采样进行连续上肢控制。最近使用间歇性视觉呈现的工作（即，频闪视觉）以促进一般和特定任务的视觉运动技能的学习表明，挑战但不改变与特定视觉运动任务相关的视觉运动处理的训练/学习协议可能是有效的。在这个理论背景下，我们讨论了可能影响未来培训研究有效性的方法论和设计因素。
