In this paper, we explore how observers of a reach-to-grasp action can identify and distinguish between the agent and patient (i.e. target) of the action. We investigate the hypothesis that there is a characteristic sequential structure to the observer's pattern of saccades, with the agent being fixated first, and then the target. We report an experiment which indicates that this sequence of saccades, while not ubiquitous, is overwhelmingly more likely than chance. The experiment also sheds some light on the mechanisms which allow the observer to saccade from the agent of the action to the target.
在本文中，我们探讨了伸手抓握动作的观察者如何识别并区分该动作的施动者和受动者（即目标）。我们研究了这样一个假设：观察者的眼跳模式存在一种特征性的顺序结构，即先注视施动者，然后注视目标。我们报告了一项实验，该实验表明这种眼跳顺序虽并非普遍存在，但比随机情况出现的可能性要大得多。该实验还对使观察者能够从动作的施动者眼跳到目标的机制有所揭示。
