This volume covers a broad range of current research topics addressing the function of visuospatial attention and working memory. It discusses a variety of perspectives ranging from evolutionary and genetic underpinnings to neural substrates/computational processes and the connection between attention and working memory. Contributions address the topic at the molecular, system and evolutionary scales and will be of interest to a range of audiences from animal behaviour specialists, experimental psychologists to clinicians in the field of psychiatry and neurology.
Publisher Description
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.
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--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.
Working memory is the cognitive system in charge of the temporary maintenance of information in view of its on-going processing. Lying at the centre of cognition, it has become a key concept in psychological science. The book presents a critical review and synthesis of the working memory literature, and also presents an innovative new theory - the Time-Based Resource-Sharing (TBRS) model. Tracing back the evolution of the concept of working memory, from its introduction by Baddeley and Hitch in 1974 and the development of their modal model, Barrouillet and Camos explain how an alternative conception could have been developed from the very beginning, and why it is needed today. This alternative model takes into account the temporal dynamics of mental functioning. The book describes a new architecture for working memory, and provides a description of its functioning, its development, the sources of individual differences, and hints about neural substrates. The authors address central and debated questions about working memory, and also more general issues about cognitive architecture and functioning. Working Memory: Loss and Reconstruction will be essential reading for advanced students and researchers of the psychology of memory.
Attention and Memory brings together and assesses past and present research on information processing, to formulate a model of this entire system.
Using the highly influential working memory framework as a guide, this textbook provides a clear comparison of the memory development of typically developing children with that of atypical children. The emphasis on explaining methodology throughout the book gives students a real understanding about the way experiments are carried out and how to critically evaluate experimental research. The first half of the book describes the working memory model and goes on to consider working memory development in typically developing children. The second half of the book considers working memory development in several different types of atypical populations who have intellectual disabilities and/or developmental disorders. In addition, the book considers how having a developmental disorder and/or intellectual disabilities may have separate or combined effects on the development of working memory. The Development of Working Memory in Children is for undergraduate and postgraduate students taking courses in development/child psychology, cognitive development and developmental disorders.
The thirty-two contributions discuss evidence from psychological experiments with healthy and brain-damaged subjects, functional imaging, electrophysiology, and computational modeling.
In this timely and comprehensive text, Cesare Cornoldi and Tomaso Vecchi describe their recently developed experimental approach to the investigation of visuo-spatial cognition, based upon the analysis of individual differences. A review of the most influential theoretical advances in the study of visuo-spatial cognition is presented, including both critical analysis and comparisons between the distinct approaches. In addition, the authors describe recent research into memory for spatial configurations, mental manipulation and the active integration of visuo-spatial information. This includes studies on the effects of congenital blindness on mental imagery abilities, developmental and age-related modifications, gender effects, and the role of genetic syndromes in determining visuo-spatial abilities. The authors draw together these distinct areas of research and integrate the findings within an innovative framework of working memory. This text will be a valuable resource for advanced undergraduate and postgraduate students of psychology, as well as researchers in the fields of cognitive psychology, neuropsychology and neuroscience.
