Several studies have demonstrated the existence of a link between action observation (AO) and language. However, the optimizing parameters for this link have not been explored until now. To answer this question, the present study proposed two experiments for assessing the role of motor repertory and attentional focus. Sixty participants performed a priming task in which they had to decide if a verb was or was not an action verb after they saw a point-light display (PLD) representing an action. Only one difference distinguished the experiments. In experiment one, the PLD was either in accordance or not with the gender kinematics of the observer, whereas in the second experiment, the PLD either focused on or was unfocused on the main limbs implied in the action. The results show that motor repertory affects the link between action observation and action verb processing, whereas attentional focus does not. Implications of these results are highlighted in the discussion, notably to better understand the mechanisms that explain the link between action observation and action verb processing.
几项研究已经证明了动作观察（AO）和语言之间存在联系。然而，直到现在，人们还没有探索这种联系的优化参数。为了回答这个问题，本研究提出了两个实验来评估运动 repertory 和注意力焦点的作用。60 名参与者进行了一项启动任务，他们在看到代表动作的点光显示（PLD）后，必须判断一个动词是否是动作动词。两个实验只有一个区别。在实验一中，PLD 要么与观察者的性别运动学一致，要么不一致，而在第二个实验中，PLD 要么集中在动作中暗示的主要肢体上，要么不集中在主要肢体上。结果表明，运动 repertory 影响动作观察和动作动词处理之间的联系，而注意力焦点则没有。这些结果的意义在讨论中得到了强调，特别是为了更好地理解解释动作观察和动作动词处理之间联系的机制。
