以往的研究表明，使用一种工具在短时间内改变了身体图式中的近体空间知觉和臂长表征。然而，到目前为止，没有研究专门调查的影响工具使用的行动相关的知觉任务。我们在这里报告的一项研究评估的影响工具使用的感知可达空间的感知估计参考的工具或手。使用工具的远端对象导致的延伸的感知可达空间的工具，并减少了可达性估计的变化。工具的使用也扩大了感知的可达空间的手，但随之而来的可达性估计的可变性增加。这些研究结果表明，工具纳入代表手臂工具使用后，提高了预期的行动可能性的工具，而手的代表变得不那么准确。(C)2014爱思唯尔有限公司版权所有。
Previous studies have shown that using a tool modifies in a short time-scale both near-body space perception and arm-length representation in the body schema. However, to date no research has specifically investigated the effect of tool-use on an action-related perceptual task. We report here a study assessing the effect of tool-use on the perception of reachable space for perceptual estimates made in reference to either the tool or the hand. Using the tool on distal objects resulted in an extension of perceived reachable space with the tool and reduced the variability of reachability estimates. Tool use also extended perceived reachable space with the hand, but with a concomitant increase of the variability of reachability estimates. These findings suggest that tool incorporation into the represented arm following tool-use improves the anticipation of action possibilities with the tool, while hand representation becomes less accurate.
