Variation in Working Memory


Book Description

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 Capacity


Book 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.




Handbook of Individual Differences in Cognition


Book Description

As cognitive models of behavior continue to evolve, the mechanics of cognitive exceptionality, with its range of individual variations in abilities and performance, remains a challenge to psychology. Reaching beyond the standard view of exceptional cognition equaling superior intelligence, the Handbook of Individual Differences in Cognition examines the latest findings from psychobiology, cognitive psychology, and neuroscience, for a comprehensive state-of-the-art volume. Breaking down cognition in terms of attentional mechanisms, working memory, and higher-order processing, contributors discuss general models of cognition and personality. Chapter authors build on this foundation as they revisit current theory in such areas as processing effort and general arousal and examine emerging methods in individual differences research, including new data on the role of brain plasticity in cognitive function. The possibility of a unified theory of individual differences in cognitive ability and the extent to which these variables may account for real-world competencies are emphasized, and commentary chapters offer suggestions for further research priorities. Coverage highlights include: The relationship between cognition and temperamental traits. The development of autobiographical memory. Anxiety and attentional control. The neurophysiology of gender differences in cognitive ability. Intelligence and cognitive control. Individual differences in dual task coordination. The effects of subclinical depression on attention, memory, and reasoning. Mood as a shaper of information. Researchers, clinicians, and graduate students in psychology and cognitive sciences, including clinical psychology and neuropsychology, personality and social psychology, neuroscience, and education, will find the Handbook of Individual Differences in Cognition an expert guide to the field as it currently stands and to its agenda for the future.




The Development of Working Memory


Book Description

This Special Issue of the International Journal of Behavioral Development brings together research on the development of working memory that arises within two quite different approaches.




Working Memory and Human Cognition


Book Description

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.




The Cognitive Neuroscience of Working Memory


Book Description

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.




The Wiley Handbook of Cognitive Control


Book Description

Covering basic theory, new research, and intersections with adjacent fields, this is the first comprehensive reference work on cognitive control – our ability to use internal goals to guide thought and behavior. Draws together expert perspectives from a range of disciplines, including cognitive psychology, neuropsychology, neuroscience, cognitive science, and neurology Covers behavioral phenomena of cognitive control, neuroanatomical and computational models of frontal lobe function, and the interface between cognitive control and other mental processes Explores the ways in which cognitive control research can inform and enhance our understanding of brain development and neurological and psychiatric conditions




Visual Memory


Book Description

Vision and memory are two of the most intensively studied topics in psychology and neuroscience. This book provides a state-of-the-art account of visual memory systems. Each chapter is written by an internationally renowned researcher, who has made seminal contributions to the topic.




Visuo-spatial Working Memory and Individual Differences


Book Description

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.




Working Memory and Language


Book Description

This book evaluates the involvement of working memory in five central aspects of language processing: vocabulary acquisition, speech production, reading development, skilled reading, and comprehension. The authors draw upon experimental, neuropsychological and developmental evidence in a wide-ranging evaluation of the contribution of two components of working memory to each aspect of language. The two components are the phonological loop, which is specialised for the processing and maintenance of verbal material, and the general-purpose processing system of the central executive. A full introduction to the application of the working memory model to normal adults, neuropsychological patients and children is provided in the two opening chapters. Non-experts within this area will find these chapters particularly useful in providing a clear statement of the current theoretical and empirical status of the working memory model. Each of the following chapters examines the involvement of working memory in one specialised aspect of language processing, in each case integrating the available experimental, neuropsychological and developmental evidence. The book will therefore be of direct relevance to researchers interested in both language processing and memory. Working Memory and Language is unique in that it draws together findings from normal adults, brain-damaged patients, and children. For each of these populations, working memory involvement in language processing ranging from the speech production to comprehension are evaluated. Working Memory and Language provides a comprehensive analysis of just what roles working memory does play in the processing of language.
