This volume approaches the issues of change and development from the intersection of theory, method, and application. It will appeal to developmentalists working in any or all of these areas, be they students or professionals.

This book explores the central importance of adolescents' own activities in their development. This focus harkens back to Jean Piaget's genetic epistemology and provides a theoretically coherent vision of what makes adolescence a distinctive period of development, with unique opportunities and vulnerabilities. An interdisciplinary and international group of contributors explore how adolescents integrate neurological, cognitive, personal, interpersonal, and social systems aspects of development into more organized systems.
