Perception is influenced by the perceiver's ability to perform intended actions. For example, when people intend to reach with a tool to targets that are just beyond arm's reach, the targets look closer than when they intend to reach without the tool (J. K. Witt, D. R. Proffitt, & W. Epstein, 2005). This is one of several examples demonstrating that behavioral potential affects perception. However, the action-specific processes that are involved in relating the person's abilities to perception have yet to be explored. Four experiments are presented that implicate motor simulation as a mediator of these effects. When a perceiver intends to perform an action, the perceiver runs a motor simulation of that action. The perceiver's ability to perform the action, as determined by the outcome of the simulation, influences perceived distance.
感知会受到感知者执行预期动作能力的影响。例如，当人们打算用工具够到超出手臂可及范围的目标时，这些目标看起来比他们打算不用工具够到时更近（J.K. 维特、D.R. 普罗菲特和W. 爱泼斯坦，2005）。这是表明行为潜能会影响感知的几个例子之一。然而，将人的能力与感知联系起来所涉及的特定动作过程尚未得到探索。本文呈现了四项实验，这些实验表明运动模拟是这些效应的中介因素。当感知者打算执行一个动作时，感知者会对该动作进行运动模拟。由模拟结果所决定的感知者执行该动作的能力会影响感知距离。
