Résumé: Research on robot groups has often applied psychological principles underlying group processes between humans to interactions with and between robots. However, such research has failed to test empirically whether these principles indeed apply to the robot context. For instance, the notion of a social group may be interpreted differently when facing human versus robot groups. Basic research on this issue is missing. Therefore, the present experiment aimed at integrating social psychological theorizing and research on robot groups by utilizing the principles of group entitativity. We examined the effect of robot number and similarity on the perception of these robots as a (social) group. To do so, participants saw pictures of one to ten robots, appearing low or high in similarity. Results showed that the aspects eliciting the perception of a social "group" in humans seem to differ from the factors evoking robot group perception. According to our findings, at least three robots seem necessary for the perception of a robot "group" to emerge. Social psychological research, however, has proposed that two persons suffice to elicit the notion of a human social group. Basic research is needed to substantiate assumptions drawn from social psychological theorizing before translating it into human-robot context.
