Arnstein, citing his own experiences both as clinician and as former young adult, presents an elegant, articulate review of professional writing on this subject. He reviews the commonly agreed-upon tasks of late adolescent development: "1. separation from parents, 2. ego synthesis or identity formation, 3. development of a

capacity for intimacy, 4. achievement of genital primacy, 5. change in object relations, 6. stabilization of character structure, 7. development of a time perspective, 8. development of a capacity for friendship, 9. commitment to a set of life goals, 10. achievement of an effective moral code." He then discusses the conscious and unconscious processes involved in achieving these goals in people between the ages of approximately seventeen and twenty-two. He notes that the psychological work usually continues, at least in part, well beyond twenty-two.
