This study investigated the role of action constraints related to an object as regards allocentric distance estimation in extrapersonal space. In two experiments conducted in both real and virtual environments, participants intending to push a trolley had to estimate its distance from a target situated in front of them. The trolley was either empty (i.e., light) or loaded with books (i.e., heavy). The results showed that the estimated distances were larger for the heavy trolley than for the light one, and that the actual distance between the participants and the trolley moderated this effect. This data suggests that the potential mobility of an object used as a reference affects distance estimation in extrapersonal space. According to embodied perception theories, our results show that people perceive space in terms of constraints related to their potential actions.
本研究调查了与物体相关的行动限制在个人空间以外的空间中以自我为中心的距离估计方面所起的作用。在真实环境和虚拟环境中进行的两项实验中，打算推一辆手推车的参与者必须估计手推车与位于他们前方的目标之间的距离。手推车要么是空的（即轻的），要么装满了书（即重的）。结果表明，重手推车的估计距离比轻手推车的估计距离更大，并且参与者与手推车之间的实际距离调节了这种效应。这些数据表明，用作参考的物体的潜在移动性会影响个人空间以外的空间中的距离估计。根据具身认知理论，我们的结果表明，人们根据与他们潜在行动相关的限制来感知空间。
