Abstract: Self-recognition is an ability where individuals realize the relationship between themselves and an image in the mirror using various clues. In past three decades, self recognition studies of nonhuman primates have deepened in scope and significance by using various research paradigms and methodologies. Research in this area not only provides deeper insight into and explanation for complex cognitive abilities, but also interactions between behavior and cognition. Currently, with this research widely undertaken in foreign countries, the domestic literature on this subject is relatively weak. This article introduce a mirror-based experiment as well as outlining the basic research paradigm of self-recognition studies, the advantages of video observation and face recognition. In conclusion, this article proposes the future prospects of clearly defining procedures in self-recognition studies with the goal of expanding the domestic research field.
