Intended as a text for upper-level students of developmental psychology, this volume presents a collection of work by leading researchers in lifespan development topics: infant-care practices; children's memory development within the context of sexual abuse; correlates of adolescent pregnancy and parenthood; and design and evaluation of interventions in nursing homes. This work explores how developmental science can help solve problems facing individuals at different points in the lifespan. It focuses on application and demonstrates how developmental research and theory guide intervention strategies.
