With the rapid development of Computer Mediated Communication (CMC), the influence
of Emoji on cooperative behavior has attracted more and more researchers’ attention. Previous studies
mainly started from the social function of emotions and explored the impact of Emoji on the recipient’s
cooperative behavior by affecting the recipient’s social cognition. Based on the existing research results,
this paper combs the influencing mechanism of emojis on cooperative behavior in the context of CMC
from the perspective of emotions, and puts forward new ideas for future research: verifying the functional
equivalence of Emoji and other modes of Emoji, improving the ecological validity of research, and
strengthening the research on social perception of Emoji.
