Recent evidence suggests adults and infants selectively attend to features of action, such as how a hand contacts an object. The current research investigated whether this bias stems from infants' processing of the functional consequences of grasps: understanding that different grasps afford different future actions. A habituation paradigm assessed 10-month-old infants' (N = 62) understanding of the functional consequences of precision and whole-hand grasps in others' actions, and infants' own precision grasping abilities were also assessed. The results indicate infants understood the functional consequences of another's grasp only if they could perform precision grasps themselves. These results highlight a previously unknown aspect of early action understanding, and deepen our understanding of the relation between motor experience and cognition.
最近的证据表明，成人和婴儿会选择性地关注动作的特征，例如手如何接触物体。当前的研究调查了这种偏见是否源于婴儿对抓握功能后果的处理：理解不同的抓握方式提供了不同的未来动作。习惯化范式评估了 10 个月大婴儿（N = 62）对他人动作中精确抓握和全手抓握功能后果的理解，同时还评估了婴儿自己的精确抓握能力。结果表明，婴儿只有在自己能够进行精确抓握的情况下，才会理解他人抓握的功能后果。这些结果突出了早期动作理解的一个以前未知的方面，加深了我们对运动经验和认知之间关系的理解。
