Social organization in virtual settings depends on proximity to human visual aspect

摘要

Virtual environments are inherently social spaces, in which humans interact through avatars. However, the parameters which favor inter-individual social structuring in those settings are still far to be understood. Particularly, the putative influence of anthropomorphic similarity of visual aspect on social organization of avatars is a key issue to understand the cognitive processes used to form social interactions in virtual worlds. Using the highly popular massively multiplayer online role-playing game World of Warcraft as a model of socially-active virtual setting, we analyzed the social behavior of 11,649 avatars as a function of their visual aspect. Our results show that social structuring in virtual settings depends on proximity to human visual aspect. Social groups formed by human-like avatars display more homogeneity than what the optimal use of the interface would predict, while this effect is not observed for social groups formed by non-human avatars. Thus, immersion in virtual environments depends more on visually-triggered social dynamics (role-play) than on optimal use of the interface (game-play). Furthermore, social aspect may override the immediate reward of interface optimization, thus representing a major factor of immersion in virtual environments.
