与步行相比，使用轮椅移动需要更大的空间。两个实验被用来测试非残障成年人估计轮椅使用的空间需求的能力。参与者从远处判断不同宽度的门状孔口是否可以通过。实验一表明，参与者低估了轮椅使用的空间需求，但高估了步行的空间需求。实验2表明，经过8天的穿孔练习后，他们的低估有所改善，但并未完全消除。对轮椅在练习条件下的表现的分析表明，低估可能是由于参与者在握住轮椅手环时对手的位置的误解所致。讨论了这些发现的理论和实践意义。
Locomotion using a wheelchair requires a wider space than does walking. Two experiments were conducted to test the ability of nonhandicapped adults to estimate the spatial requirements for wheelchair use. Participants judged from a distance whether doorlike apertures of various widths were passable or not passable. Experiment I showed that participants underestimated the spatial requirements for wheelchair use but overestimated the spatial requirements for walking. Experiment 2 showed that their underestimation improved but was not completely eliminated after 8 days of practice passing through apertures. Analyses of wheelchair performance in the practice condition showed that the underestimation may have arisen from misperception of the positions of the hands when the participants were grasping the wheelchair hand-rims. The theoretical and practical implications of these findings are discussed.
