It has been argued that the communication of emotions is more di cult in computer-mediated communication (CMC) than in face-to-face (F2F) communication. The aim of this paper is to review the empirical evidence in order to gain insight in whether emotions are communicated di erently in these di erent modes of communication. We review two types of studies: (1) studies that explicitly examine discrete emotions and emotion expressions, and (2) studies that examine emotions more implicitly, namely as self-disclosure or emotional styles. Our conclusion is that there is no indication that CMC is a less emotional or less personally involving medium than F2F. On the contrary, emo-tional communication online and o ine is surprisingly similar, and if dierences are found they show more frequent and explicit emotion communication in CMC than in F2F.
