最近的研究表明，身体被用来衡量环境的程度。我们质疑身体是否被用来通过真实的动作（实验1和2）来测量高度，或者从单一角度对动作和程度做出判断（实验3和4）。首先，参与者在自然或穿着鞋子或头盔的情况下走过障碍物。参与者需要一个更大的安全边际（在较低的高度低头）时，他们被提高。在后续的实验中，参与者在视觉上匹配障碍物的高度，并判断他们是否可以在穿鞋或戴头盔的情况下从障碍物下行走。只有头盔减少视觉匹配的估计，动作判断没有什么不同时，更高。最后一个实验表明，匹配估计值的变化可能是由于缺乏戴头盔的经验。总的来说，结果表明，感知的高度是缩放的身体，当身体的高度被改变，经验可能会温和的重新缩放的高度。
Recent research shows that the body is used to scale environmental extents. We question whether the body is used to scale heights as measured by real actions (Experiments 1 and 2), or judgments about action and extent made from a single viewpoint (Experiments 3 and 4). First, participants walked under barriers either naturally or when wearing shoes or a helmet. Participants required a larger margin of safety (ducked at shorter heights) when they were made taller. In follow-up experiments, participants visually matched barrier heights and judged whether they could walk under them when wearing shoes or a helmet. Only the helmet decreased visually matched estimates; action judgments were no different when taller. The final experiment suggested that the change in matched estimates may have been due to lack of experience wearing the helmet. Overall, the results suggest that perceived height is scaled to the body and that when body height is altered, experience may moderate the rescaling of height.
