It has been proposed that the ability to make sense of other agents' behavior relies on the activation of internal mechanisms that map action perception onto action execution. In this study we explored the constraints on this ability introduced by eyeheight-scaled information in the optic array. Short and tall participants provided maximum overhead reaching judgments for themselves and another participant. Perceptual information was manipulated by changing the participants' optically specified eyeheight. Observers were modestly accurate in perceiving maximum overhead reach for themselves and for another actor whose action capabilities differed. Perceived maximum overhead reach increased for both self- and other-judgments when the perceiver's eyeheight was increased. The results suggest an important role of perceptual information that has gone unrecognized in existing accounts of action understanding and prediction.
有人提出，理解其他主体行为的能力依赖于内部机制的激活，这些机制将动作感知映射到动作执行上。在本研究中，我们探讨了视觉阵列中与眼睛高度相关的信息对这种能力的限制。高矮不同的参与者对自己和另一名参与者的最大头顶够物高度进行了判断。通过改变参与者视觉上确定的眼睛高度来操纵感知信息。观察者在感知自己和动作能力不同的另一个行为者的最大头顶够物高度时，准确性一般。当感知者的眼睛高度增加时，自我判断和对他人的判断中，感知到的最大头顶够物高度都会增加。研究结果表明，在现有的动作理解和预测理论中未被认识到的感知信息起着重要作用。
