This book describes the first comprehensive experimental research program on an individual who exhibits exceptional memory. Rajan Mahadevan, the subject of these investigations, won a place in the Guinness Book of Records for reciting pi to 31,811 decimal places, can learn matrices up to size 20 X 20, and can produce memory spans above 60 for digits. Utilizing the methodology and theories of modern cognitive psychology, the authors systematically investigated Rajan's memory skills. A wide range of experiments and tests were conducted with Rajan and four control subjects. These include memory span tests for digits and letters, memory for various kinds of non-numeric information, tests of working memory, learning and retention of numeric matrices, memory and visual searches of the digits of pi, and lexical decision tasks with the digits of pi. The authors describe how they came to understand the way Rajan stored and now retrieves the decimal digits of pi, how he learns and retrieves matrices, and how he encodes and retrieves digits in a memory span task. Although his strategy for memorizing and retrieving digits is unique in the literature on people with extraordinary memory, the authors show how their investigations of Rajan contribute to our understanding of memory.

As a child, Meer Logan was haunted by bizarre memories and faint strains of elusive music. Now a strange letter beckons her to Vienna, promising to unlock the mysteries of her past. With each step, she comes closer to remembering connections between a clandestine reincarnationist society, Beethoven's lost flute and journalist David Yalom. David knows loss firsthand--terrorism took his entire family. Now, beneath a concert hall in Vienna, he plots a violent wake-up call to illustrate the world's need for true security. Join international bestselling author M. J. Rose in her unforgettable novel about a woman paralyzed by the past, a man robbed of his future and a secret centuries old.

By analyzing the results of experiments that use a wide variety of training tasks including those that were predominantly perceptual, cognitive, or motoric, this volume answers such questions as: Why do some people forget certain skills faster than others? What kind of training helps people retain new skills longer? Inspired by the work of Harry Bahrick and the concept of "permastore," the contributors explore the Stroop effect, mental calculation, vocabulary retention, contextual interference effects, autobiographical memory, and target detection. They also summarize an investigation on specificity and transfer in choice reaction time tasks. In each chapter, the authors explore how the degree to which reinstatement of training procedures during retention and transfer tests accounts for both durability and specificity of training. Researchers and administrators in education and training will find important implications in this book for enhancing the retention of knowledge of skills. "You have to read this book. Anyone interested in training will want to read it. This book provides the theoretical bases of the acquisition of durable skills for the next decade. It advances and demonstrates a new principle of skill learning that will prove to be as important as the encoding specificity principle and its corollary, the principle of transfer appropriate processing. This new principle is that highly practiced skill learning will be durable when the retention test embodies the procedures employed during acquisition. This principle, and the other important findings reported in this text, will have a great impact on the evolution of memory theory and on the wide range of applications." --Douglas Hermann, University of Maryland

This book examines the nature and causal antecedents of superior memory performance. The main theme is that such performance may depend on either specific memory techniques or natural superiority in the efficiency of one or more memory processes. Chapter 2 surveys current views about the structure of memory and discusses whether common processes can be identified which might underlie general variation in memory ability, or whether distinct memory subsystems exist, the efficiency of which varies independently of each other. Chapter 3 provides a comprehensive survey of existing evidence on superior memory performance. It examines techniques which underlie many examples of unusual memory performance, and concludes that not all this evidence is explicable in terms of such techniques. Relations between memory ability and other cognitive processes are also discussed. The remainder of the book describes the authors' own studies of a dozen memory experts, employing a wide variety of short- and long-term memory tasks. These studies provide a much larger body of data than previously available from studies of single individuals, usually restricted to a narrow range of tasks and rarely involving any systematic study of long-term retention. The authors argue that in some cases unusual memory ability is not dependent on the use of special techniques. They develop some objective criteria for distinguishing between subjects who demonstrate "natural" superiority and those "strategists" who depend on techniques. Natural superiority was characterised by superior performance on a wider range of tasks and better long-term retention. The existence of a general memory ability was further supported by a factor analysis of data from all subjects, omitting those who described highly-practised techniques. This analysis also demonstrated the independence of initial encoding and retention processes. The monograph raises many interesting questions concerning the existence and nature of individual differences in memory ability (a previously neglected topic), their relation to other cognitive processes and implications for theories concerning the structure of memory.

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.

Covering cognitive experiments, patients with memory disorders, the areas of the brain involved in memory, and the cognitive theory that links this research together, Memory: Foundations and Applications offers a unique emphasis on how an understanding of the science of memory can be applied to education, police investigations, courtrooms, memory clinics, and everyday life. In addition, this innovative book shows students how to use these principles to improve their own ability to learn and remember.

Basic researchers unlock the secrets of nature; applied researchers unlock the means by which those secrets of nature can change people's lives. Neither basic nor applied research has an independent impact. These volumes examine the convergence of basic and applied research in the field of memory. Volume 1: Theory and Context, focuses on the methods for understanding and applying basic memory theory, while Volume 2: Practical Applications, expands the understanding of practical memory research by providing in-depth research examples and findings. If the science of memory is to make a significant contribution to society, coordinating our basic and applied efforts and determining how they complement each other become of paramount importance. These volumes will help in this regard--both as textbooks demonstrating how to investigate memory and apply basic memory theory, and as reference sources leading to a better understanding of certain problems in basic and applied memory research. Readers of these volumes will gain a thorough grasp of the way major themes relate to basic and applied research collaboration, how programmatic basic and applied research can be conducted on particular memory problems, and the manner in which basic and applied work in major problem areas has been incorporated into the field of memory. Both volumes present important information that will be indispensable to researchers and students alike.
