For most Americans, staying "mentally sharp" as they age is a very high priority. Declines in memory and decision-making abilities may trigger fears of Alzheimer's disease or other neurodegenerative diseases. However, cognitive aging is a natural process that can have both positive and negative effects on cognitive function in older adults - effects that vary widely among individuals. At this point in time, when the older population is rapidly growing in the United States and across the globe, it is important to examine what is known about cognitive aging and to identify and promote actions that individuals, organizations, communities, and society can take to help older adults maintain and improve their cognitive health. Cognitive Aging assesses the public health dimensions of cognitive aging with an emphasis on definitions and terminology, epidemiology and surveillance, prevention and intervention, education of health professionals, and public awareness and education. This report makes specific recommendations for individuals to reduce the risks of cognitive decline with aging. Aging is inevitable, but there are actions that can be taken by individuals, families, communities, and society that may help to prevent or ameliorate the impact of aging on the brain, understand more about its impact, and help older adults live more fully and independent lives. Cognitive aging is not just an individual or a family or a health care system challenge. It is an issue that affects the fabric of society and requires actions by many and varied stakeholders. Cognitive Aging offers clear steps that individuals, families, communities, health care providers and systems, financial organizations, community groups, public health agencies, and others can take to promote cognitive health and to help older adults live fuller and more independent lives. Ultimately, this report calls for a societal commitment to cognitive aging as a public health issue that requires prompt action across many sectors.

For a variety of reasons, there has been an explosion of interest in research on aging over the past few years. The reasons include an awareness that a large and growing proportion of our popUlation is over 65 and that research findings can contribute to their health, satisfaction, and efficiency as members of society; the fact that funding agencies have endorsed the need for more research effort in the area by setting up special programs; and also the fact that researchers themselves are turning more to practical problems as many theoretical issues (in experimen tal psychology at least) seem to remain as intractable as ever. Thus, at present there is widespread interest in aging, but there is also a lack of knowledge as to what has already been accomplished in the area, what the theoretical issues are, and what factors contribute to the methodological and practical difficulties. The time is propitious for meetings of experts in various aspects of the aging process, both to discuss among themselves latest advances in the field and also to inte grate known information for researchers and practitioners. In the summer of 1980 we organized such a meeting as the 10th annual psychology symposium to be held at the Erindale Campus of the University of Toronto. The topic chosen was Aging and Cognitive Processes, and the edited contributions to the symposium form the chapters of the present book.

Possible new breakthroughs in understanding the aging mind that can be used to benefit older people are now emerging from research. This volume identifies the key scientific advances and the opportunities they bring. For example, science has learned that among older adults who do not suffer from Alzheimer's disease or other dementias, cognitive decline may depend less on loss of brain cells than on changes in the health of neurons and neural networks. Research on the processes that maintain neural health shows promise of revealing new ways to promote cognitive functioning in older people. Research is also showing how cognitive functioning depends on the conjunction of biology and culture. The ways older people adapt to changes in their nervous systems, and perhaps the changes themselves, are shaped by past life experiences, present living situations, changing motives, cultural expectations, and emerging technology, as well as by their physical health status and sensory-motor capabilities. Improved understanding of how physical and contextual factors interact can help explain why some cognitive functions are impaired in aging while others are spared and why cognitive capability is impaired in some older adults and spared in others. On the basis of these exciting findings, the report makes specific recommends that the U.S. government support three major new initiatives as the next steps for research.

As our society ages, the topic of cognitive aging is becoming increasingly important. This volume provides an accessible overview of how the cognitive system changes as a function of normal aging. Building on the successful first edition, this volume provide an even more comprehensive coverage of the major issues affecting memory, attention, language, speech and other aspects of cognitive functioning. The essential chapters from the first edition have been thoroughly revised and updated and new chapters have been introduced which draw in neuroscience studies and more applied topics. In addition, contributors were encouraged to ensure their chapters are accessible to students studying the topic for the first time. This therefore makes the volume appealing as a textbook on senior undergraduate and graduate courses.

Decades of research have demonstrated that normal aging is accompanied by cognitive change. Much of this change has been conceptualized as a decline in function. However, age-related changes are not universal, and decrements in older adult performance may be moderated by experience, genetics, and environmental factors. Cognitive aging research to date has also 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. This handbook provides a comprehensive overview of cutting-edge cognitive aging research through the lens of a life course perspective that takes into account both behavioral and neural changes. Focusing on the fundamental principles that characterize a life course approach - genetics, early life experiences, motivation, emotion, social contexts, and lifestyle interventions - this handbook is an essential resource for researchers in cognition, aging, and gerontology.

The study of age-related changes in cognitive processes is flourishing as never before, making the area an exciting one for a growing number of researchers. In addition, cognitive aging research is moving out from its traditional roots in experimental and developmental psychology -- creating increased contact with cognitive neuropsychology and cognitive neuroscience. To reflect these changes in the field, this volume includes chapters on abnormal aging, the neuroscience of aging, and applied cognitive psychology along with the core section on basic cognitive processes. While other recent compilations of research in this area have given relatively brief overviews of the literature, the contributors were given space to review each topic in depth, asked to evaluate the field -- not simply their own contributions -- and to provide critical commentaries from their personal perspectives. Couched most often in terms of cognitive or information-processing models, the general perspective of the contributors is a biologically-based account of aging. This shared viewpoint gives the volume particular coherence in its treatment of theories and data. Topics covered include age differences in attention, perception, memory, knowledge representation, reasoning, and language as well as their neuropsychological and neurological correlates and practical implications.

Presented in this volume is a discussion of current literature and theoretical issues relating to three aspects of late-life age-related cognitive change. Firstly, evidence regarding aging and the basic mental processes of attention, motor control, memory, language, problem-solving, and intelligence are presented. Secondly, the role of personal traits such as personality and self-efficacy in the aging of cognitive function are developed, along with self-awareness of cognitive processes and age changes in the monitoring of these processes. Thirdly, consideration is given to the study of interventions to delay or remediate the cognitive declines of aging.
