Debating Emerging Adulthood ─ Stage or Process?

The transition from adolescence to adulthood has undergone significant changes in recent decades. Unlike a half-century ago, when young people in industrialized countries moved from adolescence into young adulthood in relatively short order at around age 20, now the decade from the late teens to the late twenties is seen as an extended time of self-focused exploration and education in pursuit of optimally fulfilling relationships and careers. Recognition of this new period is stronger than ever, but an important question remains: should emerging adulthood be considered a developmental stage, or a process?

In Debating Emerging Adulthood: Stage or Process? two pairs of developmental psychologists take sides in a debate that is central to the very concept of emerging adulthood. Arnett and Tanner argue that as young people around the world share demographic similarities, such as longer education and later marriage, the years between the ages 18 and 25 are best understood as entailing a new life stage. However, because the experiences of emerging adults worldwide vary according to cultural context, educational attainment, and social class, these two scholars suggest that there may not be one but many different emerging adulthoods. An important issue for this burgeoning area of inquiry is to explore and describe this variation. In contrast, Hendry and Kloep assert that stage theories have never been able to explain individual transitions across the life course; in their view, stage theories---including the theory of emerging adulthood---ought to be abolished altogether, and explanations found for the processes and mechanisms that govern human change at any age. This engaging book maps out the argument of "stage or process" in detail, with vigorous disagreements, conflicting alternatives, and some leavening humor, ultimately even finding some common ground. Debating Emerging Adulthood is an absolute must-read for developmental psychologists as well as anyone interested in this indisputably important time of life.
