Book Description
Given the success of the previous edition of this Research Topic, we are pleased to announce the release of its second volume. Age-related changes can concurrently affect cognitive, motor, and sensory functioning and their interactions. For instance, age-related unisensory impairments have been linked to slower gait, functional mobility decline, increased risks of falls and reduced quality of life. Additionally, balance impairments have been associated with inefficient interactions between musculoskeletal and sensory systems which are often compromised in aging. Lastly, inefficient multisensory integration processes have been linked to increased falls, worse balance, slower gait, and increased cognitive impairments. Consequently, the successful interaction among sensory, motor and cognitive systems are an integral aspect for everyday life activities, which commonly deteriorate with age.

Book Description
Recently, studies on aging processes and age-related changes in behavior have been expanding considerably, probably due to the dramatic changes observed in the demographics. This increase in the overall age and proportion of elderly people has heightened the severity of problems associated with the safety and well-being of elderly persons in everyday life. Many researchers working on motor control have thus focused more intensely on the effects of age on motor control. This new avenue of research has led to programs for alleviating or delaying the specific sensory-motor limitations encountered by the elderly (e.g. falls) in an attempt to make the elderly more autonomous. The aggregation of studies from different perspectives is often fascinating, especially when the same field can serve as a common ground between researchers. Nearly all contributors to this book work on sensory-motor aging; they represent a large range of affiliations and backgrounds including psychology, neurobiology, cognitive sciences, kinesiology, neuropsychology, neuropharmacology, motor performance, physical therapy, exercise science, and human development. Addressing age-related behavioral changes can also furnish some crucial reflections in the debate about motor coordination: aging is the product of both maturational and environmental processes, and studies on aging must determine how the intricate interrelationships between these processes evolve. The study of aging makes it possible to determine how compensatory mechanisms, operating on different subsystems and each aging at its own rate, compensate for biological degenerations and changing external demands. This volume will contribute to demonstrating that the study of the aging process raises important theoretical questions.

Book Description
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.

Book Description
"Cognitive aging and Alzheimer's disease (AD) are associated with increasingly debilitating visuospatial disorientation and navigational impairments. These impairments lead older adults and AD patients to become lost during the independent exploration of familiar environments. Visuospatial deficits in aging and AD have been linked to impairments of visual motion processing, and changes in visual evoked potentials. In this dissertation, I review the literature on mechanisms of spatial orientation in aging and AD, and then discuss what is known about attentional influences on related sensory processing changes in aging and AD. I include research on visual motion evoked potentials in the study of visuospatial orientation, the utility of this neurophysiological approach in gaining insight into brain aging, and its potential utility for the objective assessment of AD. The main body of this work is devoted to the presentation of three original studies that employ visual motion evoked potentials (VMEPs) to better understand cognitive and perceptual influences on navigation and orientation in normal aging and AD. In Study One, neurophysiological and behavioral responses were measured to sequential visual stimuli simulating paths of self-movement through the environment. In this way the temporal dynamics of the cortical processing of naturalistically changing scenes were assessed in young controls (YN), older normal controls (ON), and AD patients. In Study Two, the effects of exogenously cued spatial attention on neurophysiological responses to the behaviorally relevant center of motion in optic flow were examined in YN, ON and AD subjects by interleaving valid and invalid spatial cues before the presentation of optic flow target stimuli. In Study Three, the effect of sustained, endogenous attention on neurophysiological responses was examined by superimposing optic flow and 3-letter words in a block-wise paradigm evoking electrophysiological responses that allows me to compare optic flow responses in attended versus non-attended conditions. Consistent with prior research on optic flow VMEPs in aging and AD, results showed that ON and AD subjects can be distinguished by differing characteristics of N200 perceptual response. Compared to YN subjects, both of the older groups show delayed responses. AD consistently showed diminished amplitude as well. Results from the current project support previous findings, and add a new focus on top-down, cognitive influences on perceptual processing. Most notably, these studies show group differences in the N2b component, suggestive of cognitive processing differences attributable to attention. Together these studies contribute to our understanding of both bottom-up visual and top-down behavioral effects on visuospatial orientation and navigation and further elucidate perceptual and cognitive factors in the functional decline of normal and pathological aging"--Leaves vi-vii.

Book Description
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.

Book Description
Decisions large and small play a fundamental role in shaping life course trajectories of health and well-being: decisions draw upon an individual's capacity for self-regulation and self-control, their ability to keep long-term goals in mind, and their willingness to place appropriate value on their future well-being. Aging and Decision Making addresses the specific cognitive and affective processes that account for age-related changes in decision making, targeting interventions to compensate for vulnerabilities and leverage strengths in the aging individual. This book focuses on four dominant approaches that characterize the current state of decision-making science and aging - neuroscience, behavioral mechanisms, competence models, and applied perspectives. Underscoring that choice is a ubiquitous component of everyday functioning, Aging and Decision Making examines the implications of how we invest our limited social, temporal, psychological, financial, and physical resources, and lays essential groundwork for the design of decision supportive interventions for adaptive aging that take into account individual capacities and context variables. Divided into four dominant approaches that characterize the current state of decision-making science and aging neuroscience Explores the impact of aging on the linkages between cortical structures/functions and the behavioral indices of decision-making Examines the themes associated with behavioral approaches that attempt integrations of methods, models, and theories of general decision-making with those derived from the study of aging Details the changes in underlying competencies in later life and the two prevailing themes that have emerged—one, the general individual differences perspective, and two, a more clinical focus

Book Description
An overview of today's diverse theoretical and methodological approaches to action and the relationship of action and cognition. The emerging field of action science is characterized by a diversity of theoretical and methodological approaches that share the basic functional belief that evolution has optimized cognitive systems to serve the demands of action. This book brings together the constitutive approaches of action science in a single source, covering the relation of action to such cognitive functions as perception, attention, memory, and volition. Each chapter offers a tutorial-like description of a major line of inquiry, written by a leading scientist in the field. Taken together, the chapters reflect a dynamic and rapidly growing field and provide a forum for comparison and possible integration of approaches. After discussing core questions about how actions are controlled and learned, the book considers ecological approaches to action science; neurocogntive approaches to action understanding and attention; developmental approaches to action science; social actions, including imitation and joint action; and the relationships between action and the conceptual system (grounded cognition) and between volition and action. An emerging discipline depends on a rich and multifaceted supply of theoretical and methodological approaches. The diversity of perspectives offered in this book will serve as a guide for future explorations in action science. Contributors Lawrence W.

Book Description
Age-related changes in cognitive and language functions have been extensively researched over the past half-century. The older adult represents a unique population for studying cognition and language because of the many challenges that are presented with investigating this population, including individual differences in education, life experiences, health issues, social identity, as well as gender. The purpose of this book is to provide an advanced text that considers these unique challenges and assembles in one source current information regarding (a) language in the aging population and (b) current theories accounting for age-related changes in language function. A thoughtful and comprehensive review of current research spanning different disciplines that study aging will achieve this purpose. Such disciplines include linguistics, psychology, sociolinguistics, neurosciences, cognitive sciences, and communication sciences. As of January 2019, this e-book is freely available, thanks to the support of libraries working with Knowledge Unlatched.
