Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Adolescence is one of the most fascinating and complex transitions in the human life span. Its breathtaking pace of growth and change is second only to that of infancy. Over the last two decades, the research base in the field of adolescence has had its own growth spurt. New studies have provided fresh insights while theoretical assumptions have changed and matured. This summary of an important 1998 workshop reviews key findings and addresses the most pressing research challenges.

Annotation Adolescence can be a turbulent period. Encompassing both classic and modern research, Smith explores its cultural and historical context, the biological changes to the adolescent brain, and the difficulties - the search for identity, relationship changes, risk-taking and anti-social behaviours - that adolescence brings.

Erik H. Erikson's remarkable insights into the relationship of life history and history began with observations on a central stage of life: identity development in adolescence. This book collects three early papers that—along with Childhood and Society—many consider the best introduction to Erikson's theories. "Ego Development and Historical Change" is a selection of extensive notes in which Erikson first undertook to relate to each other observations on groups studied on field trips and on children studied longitudinally and clinically. These notes are representative of the source material used for Childhood and Society. "Growth and Crises of the Health Personality" takes Erikson beyond adolescence, into the critical stages of the whole life cycle. In the third and last essay, Erikson deals with "The Problem of Ego Identity" successively from biographical, clinical, and social points of view—all dimensions later pursued separately in his work.

More children born today will survive to adulthood than at any time in history. It is now time to emphasize health and development in middle childhood and adolescence--developmental phases that are critical to health in adulthood and the next generation. Child and Adolescent Health and Development explores the benefits that accrue from sustained and targeted interventions across the first two decades of life. The volume outlines the investment case for effective, costed, and scalable interventions for low-resource settings, emphasizing the cross-sectoral role of education. This evidence base can guide policy makers in prioritizing actions to promote survival, health, cognition, and physical growth throughout childhood and adolescence.

This is the first study to examine the entire life cycle in the Middle Ages. Drawing on a wide range of secondary and primary material, the book explores the timing and experiences of infancy, childhood, adolescence and youth, adulthood, old age and, finally, death. It discusses attitudes towards ageing, rites of passage, age stereotypes in operation, and the means by which age was used as a form of social control, compelling individuals to work, govern, marry and pay taxes. The wide scope of the study allows contrasts and comparisons to be made across gender, social status and geographical location. It considers whether men and women experienced the ageing process in the same way, and examines the differences that can be discerned between northern and southern Europe. The fourteenth and fifteenth centuries suffered famine, warfare, plague and population collapse. This fascinating consideration of the life cycle adds a new dimension to the debate over continuity and change in a period of social and demographic upheaval.
