Comparative studies on understanding of self and others and its interrelationship in great apes

本研究旨在从比较认知的角度探讨人类复杂认知的进化基础。在对自我的理解方面，研究表明，类人猿对本我有一定的理解，对自己名字的发音也有一定的加工。在对他人的理解方面，他们表现出与人类相似的整体性面部图像处理，但缺乏对合作伙伴的明示性交际行为，也缺乏自我-他人-客体的三元互动，而这两个都是人类的基本特征。

The present project aimed to investigate the evolutionary basis of human complex cognition by exploring social intelligence from comparative cognitive perspectives. Regarding the understanding of self, the study showed that great ape have an understanding of proper self as well as specific processing of the sound of the own name. Regarding the understanding of others, they showed holistic processing of facial pictures in a similar way to humans, while they lacked ostensive communicative behaviors to their cooperative partner, or triadic interactions of self-other-object, which are both fundamental characteristics of humans.
