Book excerpt: The goal of this study was to test whether semantic priming in response to a word that immediately follows a related sentence or single-word is age-invariant. This was done using the N400 event-related brain potential (ERP). N400 amplitude varies inversely with semantic priming (Kutas, 1980), and this effect is larger for sentence primes than for word primes (Kutas, 1993). ERPs were recorded while 20 older (M = 71.5, SD = 6.4) and 20 young (M = 23.0, SD = 2.3) subjects read word-pairs and highly constrained sentences. Each final word varied on the degree of relatedness to the preceding context, with some being highly related (BC), moderately related (R), or unrelated (U). An Age X Context X Relatedness repeated-measures analysis of variance (ANOVA) was conducted on N400 amplitude at the .05 level of significance. Significant results were further analyzed with Tukey A post-hocs also conducted at the .05 level of significance. In young subjects, N400 amplitude showed the expected N400 effect gradient (U> R> BC) in both the sentence and word-pair contexts. N400 responses in older subjects showed no discrimination between the conditions (U = R = BC) for the word-pairs and limited discrimination (U> BC) for the sentence endings, indicating that older subjects were able to benefit from the constraints of a sentence context. These results provide electrophysiological evidence of age-related changes in semantic priming, and are interpreted in the context of the inhibition-deficit hypothesis (Hasher & Zacks, 1988) whereby older adults fail to inhibit related but irrelevant items in working memory.

Available in PDF, EPUB and Kindle. Book excerpt: Component cognitive processes have played a critical role in the development of experimental aging research and theory in psychology as attested by articles published on this theme. However, in the last five to ten years, there has been a substantial increase in the number of articles attempting to isolate a single factor (or small subset of factors) responsible for age differences in information processing. This view of aging is frequently termed the complexity model of the generalized slowing model, the primary assumption being that age differences in cognition are due simply to a relatively larger performance decrement on the part of older adults (compared to younger adults) as task complexity increases. Because generalized complexity theorists have questioned the utility of using component cognitive processes as theoretical constructs, the editors feel it is time to restate why component cognitive processes are critical to any thorough understanding of age differences in cognition. Thus the present edited volume represents an attempt to demonstrate the utility of the process-specific approach to cognitive aging. Central to this effort are illustrations of how regression analyses may provide evidence for general slowing by maximizing explained variance while at the same time obscuring local sources of variance. The book concentrates on age differences in word and language processing, because these factors relate to reading which is a critical cognitive process used in everyday life. Furthermore, age differences in word and language processing illustrate the importance of taking component cognitive processes into consideration. The breadth of coverage of the book attests to the wide range of cognitive processes involved in word and language processing.

Download or read book The Cambridge Handbook of Cognitive Aging written by Ayanna K. Thomas and published by Cambridge University Press. This book was released on 2020-05-28 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Implicit Memory written by Peter Graf and published by Psychology Press. This book was released on 2013-12-02 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immense growth of research on implicit and explicit memory is making it difficult to keep up with new methods and findings, to gauge the implications of new discoveries, and to ferret out new directions in research and theory development. The present volume provides a status report of work on implicit and explicit memory in the three areas that have contributed the bulk of what is known about this domain -- cognitive psychology, lifespan developmental psychology, and neuropsychology. Highlighting developments in methods, critical findings, and theoretical positions, this volume outlines promising new research directions. By so doing, it provides the reader with a multi-disciplinary perspective on implicit and explicit memory, and thereby enables a cross- fertilization of ideas and research. The chapters that make up this volume were written by experts on the topic of implicit and explicit memory. These contributors were asked to write for a broad audience -- for their colleagues from allied disciplines, for new researchers, for advanced undergraduate and graduate students -- to help them gain a comprehensive overview of the mushrooming research on this topic, grasp the most fundamental empirical and theoretical issues, and focus on new research directions.

Download or read book Social Cognition and Aging written by Thomas M. Hess and published by Elsevier. This book was released on 1999-06-18 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the research done in social cognition has been conducted with younger adults and may not be applicable to a much older population. Social Cognition and Aging provides a snapshot view of research that has been done with older adults or is directly applicable to this population. Focusing on issues of self identity, social interactions, and social perceptions, this book provides a broad overview of how aging affects one's own perceptions and actions as well as how others perceive and interact with the aged. Coverage includes such topics as self-control, memory, resilience, age stereotypes, moral development, and the "art" of living. With contributions from top researchers in both gerontology and psychology, this book is an important reference for academics and professionals alike in personality, cognition, social psychology, adult development, sociology, and gerontology.
Download or read book Semantic Priming written by Timothy P. McNamara and published by Psychology Press. This book was released on 2005-09-08 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semantic priming has been a focus of research in the cognitive sciences for more than thirty years and is commonly used as a tool for investigating other aspects of perception and cognition, such as word recognition, language comprehension, and knowledge representations. Semantic Priming: Perspectives from Memory and Word Recognition examines empirical and theoretical advancements in the understanding of semantic priming, providing a succinct, in-depth review of this important phenomenon, framed in terms of models of memory and models of word recognition. The first section examines models of semantic priming, including spreading activation models, the verification model, compound-cue models, distributed network models, and multistage activation models (e.g. interactive-activation model). The second section examines issues and findings that have played an especially important role in testing models of priming and includes chapters on the following topics: methodological issues (e.g. counterbalancing of materials, choice of priming baselines); automatic vs. strategic priming; associative vs. “pure” semantic priming; mediated priming; long-term semantic priming; backward priming; unconscious priming; the prime-task effect; list context effects; effects of word frequency, stimulus quality, and stimulus repetition; and the cognitive neuroscience of semantic priming. The book closes with a summary and a discussion of promising new research directions. The volume will be of interest to a wide range of researchers and students in the cognitive sciences and neurosciences.

Download or read book Variation in Working Memory written by Andrew Conway and published by Oxford University Press. This book was released on 2008-02-13 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties, older adults, and adults and children with neurological disorders. A particular strength of this volume is that each research group explicitly addresses the same set of theoretical questions, from the perspective of both their own theoretical and experimental work and from the perspective of relevant alternative approaches. Through these questions, each research group considers their overarching theory of working memory, specifies the critical sources of working memory variation according to their theory, reflects on the compatibility of their approach with other approaches, and assesses their contribution to general working memory theory. This shared focus across chapters unifies the volume and highlights the similarities and differences among the various theories. Each chapter includes both a summary of research positions and a detailed discussion of each position. Variation in Working Memory achieves coherence across its chapters, while presenting the entire range of current theoretical and experimental approaches to variation in working memory.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
