Homo prostheticus? Intercorporeality and the emerging adult-smartphone assemblage

Purpose Young people’s attachment to their smartphones is well-documented, with smartphones often described as prostheses. While prior studies typically assume a clear human/machine divide, this paper aims to build on posthuman perspectives, exploring intercorporeality, the blurring of human/technology boundaries, between emerging adults and their smartphones. The paper aims to discuss these issues. Design/methodology/approach Drawing on assemblage theory, this interpretive study uses smartphone diaries and friendship pair/small group discussions with 27 British emerging adults. Findings Participants in this study are characterized as homo prostheticus , living with and through their phones, treating them as extensions of their mind and part of their selves as they navigated between their online and offline, private and social lives. Homo prostheticus was part of a broader assemblage or amalgamation of human and non-human components. As these components interacted with each other, the assemblage could be strengthened or weakened by various technological, personal and social factors. Research limitations/implications These qualitative findings are based on a particular sample at a particular point in time, within a particular culture. Further research could explore intercorporeality in human–smartphone relationships among other groups, in other cultures. Originality/value Although other studies have used prosthetic metaphors, this paper contributes to understanding of smartphones as a prostheses in the lives of emerging adults, highlighting intercorporeality as a key feature of homo prostheticus . It also uses assemblage theory to contextualize homo prostheticus and explores factors strengthening or weakening the broader human–smartphone assemblage.
