Abstract
Considering the importance of self-disclosure in building relationships, it is vital to investigate how self-disclosure is affected via avatars in virtual environments, as they are likely to become increasingly popular. Previous work has shown that using avatars increases friendliness and honesty. However, issues such as how and what types of avatars affect self-disclosure and reciprocity have not been fully explored. We conducted a study with 108 participants (54 dyads) discussing a personal topic using one of three communication media: videoconferencing, avatars with avatar-self appearance similarity, or avatars without avatar-self appearance similarity. The results showed that self-disclosure is most encouraged via the avatars without similarity. Reciprocity was formed via both types of avatars but not videoconferencing. Interestingly, although the participants disclosed more about themselves via avatars than via videoconferencing, there was no difference in their subjective experiences. It means that avatar users can disclose more about themselves without being particularly aware that they are using avatars, which suggests the usefulness of avatars to understand people's candid thoughts and feelings. Finally, we discuss the design implications for applications requiring self-disclosure.
