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.

Book Description
The central unifying theme of this state-of-the-art contribution to research on literacy is its rethinking and reconceptualization of individual differences in reading. Previous research, focused on cognitive components of reading, signaled the need for ongoing work to identify relevant individual differences in reading, to determine the relationship(s) of individual differences to reading development, and to account for interactions among individual differences. Addressing developments in each of these areas, this volume also describes affective individual differences, and the environments in which individual differences in reading may emerge, operate, interact, and change. The scant comprehensive accounting of individual differences in reading is reflected in the nature of reading instruction programs today, the outcomes that are expected from successful teaching and learning, and the manner in which reading development is assessed. An important contribution of this volume is to provide prima facie evidence of the benefits of broad conceptualization of the ways in which readers differ. The Handbook of Individual Differences in Reading moves the field forward by encompassing cognitive, non-cognitive, contextual, and methodological concerns. Its breadth of coverage serves as both a useful summary of the current state of knowledge and a guide for future work in this area.

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.

Book Description
Research into reading development and reading disabilities has been dominated by phonologically guided theories for several decades. In this volume, the authors of 11 chapters report on a wide array of current research topics, examining the scope, limits and implications of a phonological theory. The chapters are organized in four sections. The first concerns the nature of the relations between script and speech that make reading possible, considering how different theories of phonology may illuminate the implication of these relations for reading development and skill. The second set of chapters focuses on phonological factors in reading acquisition that pertain to early language development, effects of dialect, the role of instruction, and orthographic learning. The third section identifies factors beyond the phonological that may influence success in learning to read by examining cognitive limitations that are sometimes co-morbid with reading disabilities, contrasting the profiles of specific language impairment and dyslexia, and considering the impact of particular languages and orthographies on language acquisition. Finally, in the fourth section, behavioral-genetic and neurological methods are used to further develop explanations of reading differences and early literacy development. The volume is an essential resource for researchers interested in the cognitive foundations of reading and literacy, language and communication disorders, or psycholinguistics; and those working in reading disabilities, learning disabilities, special education, and the teaching of reading.

Book Description
The rapid growth in the numbers of older people worldwide has led to an equally rapid growth in research on the changes across age in cognitive function, including the processes of moment to moment cognition known as working memory. This book brings together international research leaders who address major questions about how age affects working memory: Why is working memory function much better preserved in some people than others? In all healthy adults, which aspects of working memory are retained in later years and which aspects start declining in early adulthood? Can cognitive training help slow cognitive decline with age? How are changes in brain structures, connectivity and activation patterns related to important changes in working memory function? Impairments of cognition, and particularly of working memory, can be major barriers to independent living. The chapters of this book dispel some popular myths about cognitive ageing, while presenting the state of the science on how and why working memory functions as it does throughout the adult lifespan. Working Memory and Aging is the first volume to provide an overview of the burgeoning literature on changes in working memory function across healthy and pathological ageing, and it will be of great interest to advanced undergraduates, postgraduates and researchers in psychology and related subject areas concerned with the effects of human ageing, including several areas of medicine.

Book Description
Five experiments are described that study the relationship between measures of working memory and reading comprehension. Two experiments investigated whether the complex span measure must be similar to the reading comprehension task to be predictive of comprehension. The correlation found between reading comprehension and two reading-related complex spans was similar to those found between two arithmetic-related complex spans and comprehension. The relationship remained significant when quantitative skills were factored out. The simple digit and word spans (measured without a background task) did NOT correlate with reading comprehension. The complex span/comprehension correlations were a function of the difficulty of the background task. When the difficulty level of the reading-related or arithmetic-related background tasks was moderate, the span/comprehension correlations were higher in magnitude than when the background tasks were simple or very difficult. The third experiment showed that if serial recall was required in the span tasks, simple word span did significantly predict reading comprehension but not as well as the sentence span. The fourth experiment showed that the ordering of list lengths in the span tasks had little influence on the correlation between span scores and comprehension. The fifth experiment is the first in a series investigating variables whether variables that influence simple word span also influence the sentence word span. This study demonstrated that the word length has the same effect on the sentence span task as on the simple word span.

Book Description
Working memory – the conscious processing of information – is increasingly recognized as one of the most important aspects of intelligence. This fundamental cognitive skill is deeply connected to a great variety of human experience – from our childhood, to our old age, from our evolutionary past, to our digital future. In this volume, leading psychologists review the latest research on working memory and consider what role it plays in development and over the lifespan. It is revealed how a strong working memory is connected with success (academically and acquiring expertise) and a poor working memory is connected with failure (addictive behavior and poor decision-making). The contributions also show how working memory played a role in our cognitive evolution and how the everyday things we do, such as what we eat and how much we sleep, can have an impact on how well it functions. Finally, the evidence on whether or not working memory training is beneficial is explored. This volume is essential reading for students, researchers, and professionals with an interest in human memory and its improvement, including those working in cognitive psychology, cognitive neuroscience, developmental psychology, gerontology, education, health, and clinical psychology.
