当通过小孔时，人们会将他们的动作调整到与肩同宽，并转动肩膀或避开被认为太小而不能直线通过的小孔。携带比身体更宽的物体会产生一个人加物体的系统，个人必须考虑到这个系统，才能安全地通过小孔。本研究旨在确定个体是否将其临界点扩展到最宽的水平维度（肩部或物体宽度）。出现了两种反应：快速适应者通过保持一致的临界点来适应人加物体系统，而不管物体是否被携带，而慢速适应者在适应回到原始临界点之前最初增加了他们的临界点（高估）。研究结果表明，个人可以解释身体宽度的增加，通过缩放动作的大小，对象的宽度，但人们以不同的速度适应。
ABSTRACT When passing through apertures, individuals scale their actions to their shoulder width and rotate their shoulders or avoid apertures that are deemed too small for straight passage. Carrying objects wider than the body produces a person-plus-object system that individuals must account for in order to pass through apertures safely. The present study aimed to determine whether individuals scale their critical point to the widest horizontal dimension (shoulder or object width). Two responses emerged: Fast adapters adapted to the person-plus-object system by maintaining a consistent critical point regardless of whether the object was carried while slow adapters initially increased their critical point (overestimated) before adapting back to their original critical point. The results suggest that individuals can account for increases in body width by scaling actions to the size of the object width but people adapt at different rates.
