Self advantage effect refers to the phenomenon that people process information highly related
to themselves faster and more accurately. The self advantage effect not only exists in the stimulation of
physiological and social attributes related to self, but also can be induced by the stimulation of physical
attributes unrelated to self. This study classifies and summarizes the relevant researches on self advantage
in detail, and on this basis, proposes the direction of future research. Future research can focus on the
brain mechanism of self advantage, the boundary of self-concept, the difference between direct and
indirect self advantages, and the cultural difference of self advantage.
