在4个实验中，作者改变了虚拟环境中参与者运动的程度和性质，以检验行动对地理倾斜度估计的影响。以往的研究表明，人们会有意识地高估山坡倾斜度，但仍能准确地引导人们朝着山坡采取行动（D. R. Proffitt， M. Bhalla， R. Gossweiler, & J. Midgett, 1995）。相关研究表明，一个人的行为潜力可能影响对倾斜的感知，不同的表征可能独立地通知感知和运动反应。研究人员发现，在所有情况下，感知判断都被高估了，而运动调节更准确。虚拟环境允许操纵攀登模拟山丘所需的努力。与在平地上行走相比，以适当的视觉倾斜度行走导致对倾斜度的知觉高估增加，而视觉引导的动作仍然准确。
In 4 experiments, the authors varied the extent and nature of participant movement in a virtual environment to examine the influence of action on estimates of geographical slant. Previous studies showed that people consciously overestimate hill slant but can still accurately guide an action toward the hill (D. R. Proffitt, M. Bhalla, R. Gossweiler, & J. Midgett, 1995). Related studies suggest that one's potential to act may influence perception of slant and that distinct representations may independently inform perceptual and motoric responses. The authors found that in all conditions, perceptual judgments were overestimated and motoric adjustments were more accurate. The virtual environment allowed manipulation of the effort required to walk up simulated hills. Walking with the effort appropriate to the visual slant led to increased perceptual overestimation of slant compared with active walking with the effort appropriate to level ground, while visually guided actions remained accurate.
