现代技术逐步创造了这样的工作场所，在这些工作场所中，动作的执行和对其后果的观察在空间上是分开的。用户通过技术设备在遥远的空间进行操作的虚拟工作场所包括航空，应用医学工程和虚拟现实。当使用工具时，来自移动的手的本体感受/触觉反馈（近端动作效果）和来自工具的移动效果点的视觉反馈（诸如显示器上的移动光标）（远端动作效果）通常不对应或甚至冲突。如果近端和远端反馈对于控制工具的动作同样重要，则这种差异将是干扰的恒定来源。人类信息处理系统通过支持预期的远端动作效果而减弱或忽略近端动作效果来解决这个问题。这项研究提出了一个概述的实验，旨在在潜在的运动和认知过程和工具动作的视觉优势的局限性。主要的发现是，当转换是有效的意识自己的行动是相当低的。这在使用工具时似乎是有利的，因为它允许广泛的灵活的感觉运动适应，并且-可能更重要的是-它唤起了控制的感觉。因此，感知自己的近端动作效应的衰减是成功使用工具的重要前提。然而，整合不一致的感知-动作反馈的能力有局限性，尤其是但不仅限于复杂的转换。当视觉与本体感觉的特征重叠程度较低，且转换存在明显时，近端动作效应便开始发挥作用，并在工具动作中占据主导地位。总之，行动效果控制在理解工具转换的获取和应用的约束方面起着重要的作用。(C)2013爱思唯尔有限公司保留所有权利。
Modern technologies progressively create workplaces in which the execution of movements and the observation of their consequences are spatially separated. Challenging workplaces in which users act via technical equipment in a distant space include aviation, applied medical engineering and virtual reality. When using a tool, proprioceptive/tactile feedback from the moving hand (proximal action effect) and visual feedback from the moving effect point of the tool, such as the moving cursor on a display (the distal action effect) often do not correspond or are even in conflict. If proximal and distal feedback were equally important for controlling actions with tools, this discrepancy would be a constant source of interference. The human information processing system solves this problem by favoring the intended distal action effects while attenuating or ignoring proximal action effects. The study presents an overview of experiments aiming at the underlying motor and cognitive processes and the limitations of visual predominance in tool actions. The main findings are, that when transformations are in effect the awareness of one's own actions is quite low. This seems to be advantageous when using tools, as it allows for wide range of flexible sensorimotor adaptations and - may be more important - it evokes the feeling of being in control. Thus, the attenuation of perceiving one's own proximal action effects is an important precondition for using tools successfully. However, the ability to integrate discordant perception-action feedback has limits, especially, but not only, with complex transformations. When feature overlap between vision and proprioception is low, and when the existence of a transformation is obvious proximal action effects come to the fore and dominate action control in tool actions. In conclusion action-effect control plays an important role in understanding the constraints of the acquisition and application of tool transformations. (C) 2013 Elsevier Ltd. All rights reserved.
