In this chapter, the authors explore the role that networked platforms play in identity development during emerging adulthood. They use the stories of two youth to highlight dominant themes from existing research and to examine the developmental implications of forming one's identity in a networked era. The inquiry is theoretically informed by the work of the psychologist Erik Erikson, who depicted identity development as a process of exploration that ultimately results in a sense of personal continuity and coherence. The authors consider what insights this theory—formulated in the mid-twentieth century—has to offer in a digital world. The chapter concludes with a discussion of the practical implications relating to education, policy, and the design of new technologies.
