Is Emerging Adulthood a New Developmental Phase?

In 2000, Jeffrey Arnett, a developmental research psychologist, proposed a new phase of development that he called “emerging adulthood.” He delineated developmental challenges centered on identity, role exploration, and subjective experience and linked his observations to changes in the demographics and culture of contemporary society. This proposal elicited an extraordinary response in the research community, but the reaction among psychoanalysts has been tepid at best: developmental phases have not been amended for almost a century, and in some schools the very notion of such phases has been discredited. Adult development has historically attracted mostly lifespan psychoanalysts, and the concept of identity has never achieved full psychoanalytic status. But both adulthood and identity merit psychoanalytic legitimacy: adulthood because it looms in the mind as a meaningful endpoint that shapes earlier stages, and identity because it is a complex, organizing aspect of self-representation. The concept of emerging adulthood, too, has sufficient validity and heuristic value to be considered a developmental phase, provided we loosen our fixed ideas about what constitutes “developmental” and take a fresh look at the sweep of human development as it is shaping up in a transformed world.
