"Decades of research have demonstrated that normal aging accompanies cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal. Oft-found decrements in older adult performance may be moderated by experience, genetics, and environmental factors. To date, cognitive aging has largely emphasized biological changes in the brain, with less evaluation of the range of external contributors to behavioral manifestations of age-related decrements in performance. The goal of this book is to examine cognitive aging through the lens of a life course perspective. Understanding cognition within the context of both the life-span (aging) and the life-course (experience) is a relatively new approach to the field of cognitive aging. However, the approach has already pushed the field forward in theoretically and practically important ways. This edited volume will focus on fundamental principles that characterize a life course approach to cognitive aging by (1) presenting an overview of lifespan and life course models of cognitive aging; (2) presenting the recent state of domain-specific models; (3) considering older cognition in socioemotional contexts; (4) considering the influences of early life and biological predispositions (5) and ending with a review of later life interventions"--
