Here, Daniel A. Hart analyzes the results of an intensive twenty-year longitudinal study of men's development. Integrating a wide range of research approaches, Hart assesses personality trait, structural-developmental, and crisis-transformational factors in the study of lives followed over time. The author then develops an original framework for understanding the psychological similarities and differences in men's lives.
