感知自我中心距离不仅是与之相关的光学变量的函数，而且是人们执行预期动作的当前生理潜力的函数。在一组实验中，我们发现，随着与行走相关的努力的增加，感知距离增加，如果感知者打算走的程度，但如果感知者打算扔。相反，随着与投掷相关的努力的增加，如果人们打算向目标投掷，则感知距离增加，但如果他们打算步行，则不会增加。感知距离将世界的几何形状与我们的行为目标以及我们身体实现这些目标的潜力结合起来。
Perceiving egocentric distance is not only a function of the optical variables to which it relates, but also a function of people's current physiological potential to perform intended actions. In a set of experiments, we showed that, as the effort associated with walking increases, perceived distance increases if the perceiver intends to walk the extent, but not if the perceiver intends to throw. Conversely, as the effort associated with throwing increases, perceived distance increases if people intend to throw to the target, but not if they intend to walk. Perceiving distance combines the geometry of the world with our behavior goals and the potential of our body to achieve these goals.
