This book was released on 1998 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: While AD patients typically demonstrate impairment on "conceptually-driven" priming tasks, discrepant findings have emerged with regard to their performance on "data-driven," or perceptual, priming tasks. In an attempt to explain this variable priming performance, Gabrieli et al. (1994) proposed that implicit memory tasks may be driven by two separate systems: one mediating memory for "lexical-semantic" information and the other mediating memory for "perceptual-structural" material. The performance of AD patients on a series of perceptual priming tasks was examined. First, the possibility was addressed that findings of intact perceptual priming in AD may be partially explained by inadequate task sensitivity. Thus, within all experiments, (1) a finer measure of priming performance was used (e.g., reaction times) and (2) the test materials covered a range of difficulty. Further, experiments 2 and 3 addressed the need to evaluate perceptual priming using test materials that require little to no lexical or semantic processing. Participants were 15 AD patients and 15 age-matched normal control subjects (NCs). In experiment 1, a picture fragment identification task was administered. Findings revealed that the AD patients showed impaired priming relative to the NCs. Within experiment 2, two separate priming tasks were administered, one requiring the speeded copying of words and the other requiring the copying of patterns. Findings revealed no group difference in priming within either task, even when baseline differences in copying speed were statistically accounted for. Experiment 3 compared performance on two repetition priming tasks requiring that participants make speeded decisions about whether two stimuli were the same or different. One of the tasks used words as test stimuli while the other used meaningless objects. Findings revealed that the AD patients were significantly impaired relative to the NCs on the object, but not the word, priming task. Follow-up analyses within all three experiments revealed differential effects of item difficulty on priming performance. The current findings of impaired perceptual priming in AD in two out of five tasks do not support Gabrieli's multiple memory systems view. Degree of task sensitivity appears to influence the appearance of impaired priming performance in AD.

Available in PDF, EPUB and Kindle. Book excerpt: A negative effect of the ageing population is that more individuals are experiencing cognitive decline and some form of neurodegenerative disease. With the number of people experiencing dementia likely to double in the next 20 years, this change in society presents one of greatest challenges facing public health personnel in the 21st century. The aim of this volume is to describe research that is in progress, and the major findings that have been obtained in the scientific study of dementia. The chapters in the first section of the book focus upon early signs of dementia, and consider several approaches to finding early cognitive signs and biological markers of dementia. The second section considers whether dementia is inevitable for people who become very old, and features chapters on risk factors and proactive influences, cognitive reserve and intervention. Each chapter in the final section describes phenomena which are related to differences in function between memory systems, including anterograde memory in fronto-temporal dementia, and the role semantic memory and semantic cognition may play in developing an understanding of the development of the degenerative processes in dementia. With contributions from world-class researchers in this area, the volume offers a concise overview of key findings in recent research on dementia and memory. It will be of great interest to researchers and advanced students of cognitive psychology, and to those working in related fields, such as gerontology, rehabilitation sciences, and allied health.

Download or read book The Clinical Management of Early Alzheimer s Disease written by Reinhild Mulligan and published by Psychology Press. This book was released on 2013-05-13 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enormous human and economic toll of Alzheimer's Disease in societies in which more and more people are living into old age is well-recognized. Scientists and practitioners alike have been working to limit it. Their major focus has been patients in the later stages of the disease, when dementia is fully established. Yet patients in the early stages of cognitive decline, far more numerous, often still living independently with family members, present a bewildering variety of challenges. Bringing together leading authors with diverse expertise, this Handbook offers the first comprehensive overview of approaches to the management of early-stage issues. The authors summarize the important implications of the latest research in their own fields for: * the recognition and formal diagnosis of cognitive problems; * the assessment of specific difficulties in daily functioning; * the formulation of a management plan integrating pharmacological, neuropsychological, behavioral, and cognitive strategies; and * the facilitation and support of caregivers' efforts. All professionals involved in any way with the care of early Alzheimer's patients and their families will find this book an indispensable reference.
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 The Hippocampus Book written by Per Andersen and published by Oxford University Press. This book was released on 2007 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hippocampus is one of a group of remarkable structures embedded within the brain's medial temporal lobe. Long known to be important for memory, it has been a prime focus of neuroscience research for many years. The Hippocampus Book promises to facilitate developments in the field in a major way by bringing together, for the first time, contributions by leading international scientists knowledgeable about hippocampal anatomy, physiology, and function. This authoritative volume offers the most comprehensive, up-to-date account of what the hippocampus does, how it does it, and what happens when things go wrong. At the same time, it illustrates how research focusing on this single brain structure has revealed principles of wider generality for the whole brain in relation to anatomical connectivity, synaptic plasticity, cognition and behavior, and computational algorithms. Well-organized in its presentation of both theory and experimental data, this peerless work vividly illustrates the astonishing progress that has been made in unraveling the workings of the brain. The Hippocampus Book is destined to take a central place on every neuroscientist's bookshelf.
