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

本项目旨在从比较认知的角度探讨社会智力对人类复杂认知的进化基础。在对自我的理解方面，研究表明类人猿对正确的自我有理解，对自己名字的发音有特定的处理。在对他人的理解上，他们表现出与人类相似的面部图像整体处理方式，而缺乏与合作伙伴的显性交流行为，缺乏自我-他人-客体的三合一互动，而这两者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.
