最近的研究表明，人们对人们对范围内外空间的反应的神经系统差异和行为差异。本研究也证明了感知差异。通过有或没有工具，可以通过有或没有工具来操纵可及性。在2个条件下，参与者要么持有工具，要么在相同的距离内提出目标。与没有该工具的目标相比，持有该工具的目标距离内的目标距离被压缩。这些结果表明，可达性是感知的度量。第三实验发现，当感知者打算到达时，可达性只会影响感知的距离。这些实验表明，作者以我们在其中行动的意图和能力来感知环境。
Recent research demonstrates neurologic and behavioral differences in people's responses to the space that is within and beyond reach. The present studies demonstrated a perceptual difference as well. Reachability was manipulated by having participants reach with and without a tool. Across 2 conditions, in which participants either held a tool or not, targets were presented at the same distances. Perceived distances to targets within reach holding the tool were compressed compared with targets that were beyond reach without it. These results suggest that reachability serves as a metric for perception. The 3rd experiment found that reachability only influenced perceived distance when the perceiver intended to reach. These experiments suggest that the authors perceive the environment in terms of our intentions and abilities to act within it.
