This research draws on the social identity approach to investigate group performance in face-to-face and virtual brainstorming settings. In particular, we display Social Identity Cues (SIC) on participants or on avatars to foster group membership. We compare four conditions in a factorial design: Brainstorming in Face-to-face or Virtual setting, With or Without SIC. Seventy-two students belonging to a population with a strong social identity participated in the experiment, using their traditional clothing as SIC. The results show that the presence of SIC led to increased creative performance both in face-to-face and virtual settings. SIC also increased group identification, but only in the virtual environment. These results highlight the potential of avatars to support teamwork in a meaningful way
