为了安全有效地通过孔径，个体必须感知孔径的宽度相对于(1)人加物体系统的宽度和(2)他们（预期的）移动速度。本研究调查的是，与缺乏此类经验的运动员相比，有丰富经验的运动员在进行需要戴着垫肩穿过狭窄空间的运动时，对肩部旋转的控制是否有所不同。一组有不同运动比赛经验的运动员（美式足球、橄榄球和对照组运动员）进行了一项行为任务，他们在两个带垫肩或不带垫肩的假人之间奔跑或行走。他们还完成了一项心理物理任务，在这项任务中，他们报告了感知到的身体和垫肩的宽度。当跑过小孔时，踢美式足球的运动员表现出比对照组运动员更小的幅度和更晚的肩膀旋转。而在穿过孔洞时，没有发现这种差异。三组受试者对垫肩宽度的感知没有差异。这些发现表明，这种行为的表现是行动尺度的，是特定于任务的。(C) 2010 Elsevier B.V.版权所有
In order to pass through apertures safely and efficiently, individuals must perceive the width of the aperture relative to (1) the width of the person-plus-object system and to (2) their (anticipated) movement speed. The present study investigated whether athletes who have extensive experience playing sports that require running through narrow spaces while wearing shoulder pads control their shoulder rotations differently while performing this behavior than athletes who lack such experience. Groups of athletes with experience competing in different sports (American football, rugby, and control athletes) performed a behavioral task in which they ran or walked between two tucking dummies with or without wearing shoulder pads. They also performed a psychophysical task in which they reported perceived width of the body and shoulder pads. When running through the apertures, the athletes who played American football exhibited smaller magnitudes and later onset of shoulder rotations than control athletes. No such difference was found when walking through the apertures. There was no difference in perception of the width of the shoulder pads among three groups. These findings suggest that performance of this behavior is action-scaled and task-specific. (C) 2010 Elsevier B.V. All rights reserved.
