Cognitive And Social Neuroscience Of Aging

Integrates a neuroscience approach to study aging. In addition to covering standard cognitive functions, it incorporates socioemotional abilities.

A rapidly growing body of research has consituted a new discipline that may be called cognitive neuroscience of aging. This book offers an introduction to the topic, useful to both professionals & students in cognitive neuroscience, cognitive psychology, neuroscience, neuropsychology & neurology.

By 2030 there will be about 70 million people in the United States who are older than 64. Approximately 26 percent of these will be racial and ethnic minorities. Overall, the older population will be more diverse and better educated than their earlier cohorts. The range of late-life outcomes is very dramatic with old age being a significantly different experience for financially secure and well-educated people than for poor and uneducated people. The early mission of behavioral science research focused on identifying problems of older adults, such as isolation, caregiving, and dementia. Today, the field of gerontology is more interdisciplinary. When I'm 64 examines how individual and social behavior play a role in understanding diverse outcomes in old age. It also explores the implications of an aging workforce on the economy. The book recommends that the National Institute on Aging focus its research support in social, personality, and life-span psychology in four areas: motivation and behavioral change; socioemotional influences on decision-making; the influence of social engagement on cognition; and the effects of stereotypes on self and others. When I'm 64 is a useful resource for policymakers, researchers and medical professionals.

Until very recently, our knowledge about the neural basis of cognitive aging was based on two disciplines that had very little contact with each other. Whereas the neuroscience of aging investigated the effects of aging on the brain independently of age-related changes in cognition, the cognitive psychology of aging investigated the effects of aging on cognition independently of age-related changes in the brain. The lack of communication between these two disciplines is currently being addressed by an increasing number of studies that focus on the relationships between cognitive aging and cerebral aging. This rapidly growing body of research has come to constitute a new discipline, which may be called cognitive neuroscience of aging. The goal of Cognitive Neuroscience of Aging is to introduce the reader to this new discipline at a level that is useful to both professionals and students in the domains of cognitive neuroscience, cognitive psychology, neuroscience, neuropsychology, neurology, and other, related areas. This book is divided into four main sections. The first section describes noninvasive measures of cerebral aging, including structural (e.g., volumetric MRI), chemical (e.g., dopamine PET), electrophysiological (e.g., ERPs), and hemodynamic (e.g., fMRI), and discusses how they can be linked to behavioral measures of cognitive aging. The second section reviews evidence for the effects of aging on neural activity during different cognitive functions, including perception and attention, imagery, working memory, long-term memory, and prospective memory. The third section focuses on clinical and applied topics, such as the distinction between healthy aging and Alzheimers disease and the use of cognitive training to ameliorate age-related cognitive decline. The last section describes theories that relate cognitive and cerebral aging, including models accounting for functional neuroimaging evidence and models supported by computer simulations. Taken together, the chapters in this volume provide the first unified and comprehensive overview of the new discipline of cognitive neuroscience of aging.

The field of social cognitive neuroscience has captured the attention of many researchers during the past ten years. Much of the impetus for this new field came from the development of functional neuroimaging methods that made it possible to unobtrusively measure brain activation over time. Using these methods over the last 30 years has allowed psychologists to move from simple validation questions -- would flashing stimuli activate the visual cortex -- to those about the functional specialization of brain regions-- are there regions in the inferior temporal cortex dedicated to face processing-- to questions that, just a decade ago, would have been considered to be intractable at such a level of analysis. These so-called "intractable" questions are the focus of the chapters in this book, which introduces social cognitive neuroscience research addressing questions of fundamental importance to social psychology: How do we understand and represent other people? How do we represent social groups? How do we regulate our emotions and socially undesirable responses? This book also presents innovative combinations of multiple methodologies, including behavioral experiments, computer modeling, functional Magnetic Resonance Imaging (fMRI) experiments, Event-Related Potential (ERP) experiments, and brain lesion studies. It is divided into four sections. The first three sections present the latest research on, respectively, understanding and representing other people, representing social groups, and the interplay of cognition and emotion in social regulation. In the fourth section, contributors step back and consider a range of novel topics that have emerged in the context of social neuroscience research: understanding social exclusion as pain, deconstructing our moral intuitions, understanding cooperative exchanges with other agents, and the effect of aging on brain function and its implications for well-being. Taken together, these chapters provide a rich introduction to an exciting, rapidly developing and expanding field that promises a richer and deeper understanding of the social mind.

This title marks the emergence of a third broad perspective in neuroscience. This perspective emphasizes the functions that emerge through the coaction and interaction of conspecifics and the commonality and differences across social species and superorganismal structures.

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.
