Anthropomorphism has traditionally been viewed as a means to compensate for a lack of social connection; therefore, social deficits are considered to facilitate anthropomorphism. In this research, we adopted an alternative growth-oriented perspective of anthropomorphism. We posited that anthropomorphism operates as a means to explore the social world, and thus hypothesized that social connectedness promotes robot anthropomorphism. To test this hypothesis, we conducted three studies (total N = 599) examining the effect of social connectedness on robot anthropomorphism. We found that social connectedness increased robot anthropomorphism. Importantly, genuine interest in social interactions with robots accounted for this effect. In addition, anthropomorphism elicited by social connectedness predicted more favorable attitudes toward robots. These findings enrich the current understanding of anthropomorphism and have practical implications.
