Abstract:

Self-others overlap is the overlap of self-concept between individuals and others. In previous studies, multiple concepts of self-others overlap were proposed, and different measurements were formulated to measure the two dimensions of perceived closeness and overlapping representation. Moreover, a variety of methods were developed to modify an individual’s self-other overlap with others. Furthermore, this article analyzed the relationships between self-other overlap with relational self, self-expansion, and social distance. It was found that self-others overlap is the result of self-expanding activities through including the others’ identities, resources, and perspectives into themselves. In future, it is necessary to explore the neural mechanism of the self-other overlap, in addition to negative impacts on the interpersonal relationship.

Key words: self-other overlap, relational self, self-expansion, social distance
