摘　　要：对他人动作的理解是一种重要的社会认知和社交能力。层次模型将动作理解从低到高分为视觉运动、动作方式、动作目标和动作意图四个层次。健康人群与失用症病人的认知研究揭示了动作理解各层次的行为表现;脑成像研究发现了动作理解各层次可能涉及的功能脑区,额—顶镜像神经系统主要服务于目标、方式层次,而心智化系统更多服务于意图层次,二者相互协作但加工方式存在差异。未来还需要对顶区在各层次中的功能加以区分,对动作理解的时间机制进行深入研究。Action understanding is an important social cognitive competence and social skill. Based on hierarchical model, action understanding is divided into four levels from low to high level, i.e., visual motion, motor act, action goal, and action intention. Cognitive studies on healthy participants and apraxia have revealed the hierarchical behavior of action understanding. Brain imaging studies have showed functional brain regions related to four levels, specifically, the mirror neuron system is involved in the motor act and action goal level, whereas, the mentalizing system is involved in the action intention level. These two neural systems have distinct but collaborative processing styles. Future studies are needed to differentiate the functions of parietal regions across four levels of action understanding. It is also important to investigate the temporal mechanisms in action understanding.
