This title compares and contrasts different conceptions of working memory. This is one of the most important notions to have informed cognitive psychology over the last 20 years or so, and yet it has been used in a wide variety of ways. This is partly because contemporary usage of the phrase `working memory' encapsulates various themes that have appeared at different points in the history of research into human memory and cognition. This book presents three dominant views of working memory.
This new volume in the Counterpoints series compares and contrasts different conceptions of working memory, generally recognized as the human cognitive system responsible for temporary storage of information. The book includes proponents of several different views. Robert Logie discusses the theoretical and empirical utility of separating working memory into an articulatory loop, a phonological store, and a visuo-spatial sketchpad into visual and spatial subsystems. Patricia Carpenter provides evidence for a process view of working memory, arguing that both task-specific processing and general processing capabilities can account for the full range of working memory phenomena. She focuses on findings from reading comprehension and memory tasks suggesting that working memory is used to represent the set of skills and strategies necessary for complex tasks, while retaining residual capacity for use as a storage buffer. Lynn Hasher argues in favor of the new inhibitory model, with evidence drawn from the literature on aging and pathology that demonstrates parallels between memory disorders and normal memory functioning. Randall Engle addresses the issue of whether working memory resources are required for retrieval of information or whether that task is relatively automatic. Engle's empirical studies, in turn, bear directly on the positions of Carpenter, Hasher, and Logie. As interest in working memory is increasing at a rapid pace, an open discussion of the central issues involved is both useful and timely. This work serves this purpose for a wide audience of cognitive psychologists and their students.
Working Memory is one of the central topics in experimental psychology Offers a unique assessment and critique of the famous Baddeley and Hitch model of Working Memory Of interest to students and researchers in all areas of cognitive psychology
It is only relatively recently that it has been possible to study the neural processes that might underlie working memory, leading to a proliferation of research in this domain. This volume brings together leading researchers from around the world to summarise current knowledge of this field.
Working memory refers to how we keep track of what we are doing moment to moment throughout our waking lives. This book brings together in one volume, state-of-the-science chapters written by the most productive and well known working memory researchers worldwide.
The idea of one's memory "filling up" is a humorous misconception of how memory in general is thought to work; it actually has no capacity limit. However, the idea of a "full brain" makes more sense with reference to working memory, which is the limited amount of information a person can hold temporarily in an especially accessible form for use in the completion of almost any challenging cognitive task. This groundbreaking book explains the evidence supporting Cowan's theoretical proposal about working memory capacity, and compares it to competing perspectives. Cognitive psychologists profoundly disagree on how working memory is limited: whether by the number of units that can be retained (and, if so, what kind of units and how many), the types of interfering material, the time that has elapsed, some combination of these mechanisms, or none of them. The book assesses these hypotheses and examines explanations of why capacity limits occur, including vivid biological, cognitive, and evolutionary accounts. The book concludes with a discussion of the practical importance of capacity limits in daily life. This 10th anniversary Classic Edition will continue to be accessible to a wide range of readers and serve as an invaluable reference for all memory researchers.

The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
Representation of the visual and spatial properties of our environment is a pivotal requirement of everyday cognition. We can mentally represent the visual form of objects. We can extract information from several of the senses as to the location of objects in relation to ourselves and to other objects nearby. For some of those objects we can reach out and manipulate them. We can also imagine ourselves manipulating objects in advance of doing so, or even when it would be impossible to do so physically. The problem posed to science is how these cognitive operations are accomplished, and proffered accounts lie in two essentially parallel research endeavours, working memory and imagery. Working memory is thought to pervade everyday cognition, to provide on-line processing and temporary storage, and to update, moment to moment, our representation of the current state of our environment and our interactions with that environment. There is now a strong case for the claims of working memory in the area of phonological and articulatory functions, all of which appear to contribute to everyday activities such as counting, arithmetic, vocabulary acquisition, and some aspects of reading and language comprehension. The claims for visual and spatial working memory functions are less convincing. Most notable has been the assumption that visual and spatial working memory are intimately involved in the generation, retention and manipulations of visual images. There has until recently been little hard evidence to justify that assumption, and the research on visual and spatial working memory has focused on a relatively restricted range of imagery tasks and phenomena. In a more or less independent development, the literature on visual imagery has now amassed a voluminous corpus of data and theory about a wide range of imagery phenomena. Despite this, few books on imagery refer to the concept of working memory in any detail, or specify the nature of the working memory system that might be involved in mental imagery. This essay follows a line of reconciliation and positive critiquing in exploring the possible overlap between mental imagery and working memory. Theoretical development in the book draws on data from both cognitive psychology and cognitive neuropsychology. The aim is to stimulate debate, to address directly a number of assumptions that hitherto have been implicit, and to assess the contribution of the concept of working memory to our understanding of these intriguing core aspects of human cognition.
