This chapter examines two recursive approaches to the study of technology adoption within families and the life course: actor network theory (ANT) and strong structuration theory (SST). These recursive approaches explain the reciprocal relationship between social structure and agency in the context of technology use over time. ANT rejects any dualism between technology and society, whereas SST combines structure, agency, and context to offer a comprehensive analysis of users, technologies, and their situational dimensions. The chapter first provides an overview of the theoretical commitments ANT and SST entail for the researcher before discussing the ways in which each has been, and can be, applied in the domains of family and life course studies. It also presents two case studies to illustrate the opportunities and challenges that both recursive approaches bring with them in framing and explaining relationships between technology use, family life, and life transitions.
