Social presence refers to the degree to which a medium permits communicators to experience others as being psychologically present or the degree to which a medium is perceived to convey the actual presence of the communicating participants. Tasks that involve interpersonal skills, such as resolving disagreements or negotiation, demand high social presence, whereas tasks such as exchanging routine information require less social presence. Therefore, face-to-face media like group meetings are more appropriate for performing tasks that require high social presence; media such as email and written letters are more appropriate for tasks that require low social presence.
