Abstract: self-with-other representation refers to the self-concept when one interacts with the others, which provides a new perspective in exploring the relationship between the self and the others. There are two main viewpoints, shared representation and special representation. The former proposes that the subjects integrate the representations of other-related information into their self-concept, becoming a component of the self-concept. The process of self-related information and the process of other-related information shared some activation cortexes. And the later proposes that the presentations of self-related information and the representations of other-related information are relatively independent process, and both are based on specialized representation styles and structures. The activation cortexes are specialized for both the representation of self-related information and other-related information. Additionally, future research issues will focus on the relationship between the shared representation and the special representation, the rule of the emotion and affect in the self-with-other representation, and the influences of relationship types and degree in the self-with-other representation, and so on.

Key words: self-with-other representation, shared representation, special representation, neuronal mechanism
