"The definitive work on a groundbreaking longitudinal study, this volume provides a coherent picture of the nature of development from birth to adulthood. Explained are both the methodology of the Minnesota Study and its far-reaching contributions to understanding how we become who we are. Shedding new light on both positive development and maladaptation, the book is written by the researchers themselves. It is provocative, insightful, and informative reading for anyone studying or working with infants, children, and families."--Jacket.
