Mean rated happiness score (scale 0–10) for interactions with five best friends through six different communication media as a function of whether laughter occurred during the interaction (black bars) or not (grey bars). Laughter was recorded as both actual or virtual (e.g. the use of emoticons or acronyms such as LOL (‘laugh out loud’)). Interaction satisfaction was rated using Fordyce's [81] Happiness Measure on an 11-point Likert scale. Adapted Vlahovic et al. [80]. F2F, face-to-face; IN, instant messaging.
