When this title was originally published in 1981, the information processing approach to perception and memory was dominant in experimental psychology, and the research reported here had major implications for future development. After exploring the shortcomings of earlier work in this field, the author develops a new model which he shows to be capable of accounting for a variety of experimental data connected with human information processing, visual perception and attention. The central theme which is discussed is how we select relevant and discard irrelevant information. The basic assumption is that all incoming information is identified, that is, it reaches and activates the appropriate lexical entries. A piece of identified information is described as a unit consisting of three distinguishable codes: a visual code, a lexical or semantic code and a motor or action code. Identified information decays fast, so selective attention operates by selecting those units which have to be saved from this rapid decay. In a sense, therefore, the human information processor is described as struggling against forgetting.

Download Working Memory Capacity Book in PDF, ePub and Kindle
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.

Download Visual Memory Book in PDF, ePub and Kindle
Vision and memory are two of the most intensively studied topics in psychology and neuroscience. The present book concerns the interaction between vision and memory: How do we remember what we see? And how does our memory for the visual world influence subsequent perception and action? topics in psychology and neuroscience, and the intersection etween them--visual memory--is emerging as a fertile ground for research. Certain memory systems appear to specialize in 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. The chapters are comprehensive, providing both a broad overview of each topic and a summary of the latest research. They also present new perspectives that advance our theoretical understanding of visual memory and suggest directions for future research. After an introductory overview by the editors, chapters address visual sensory memory (iconic memory), visual short-term memory, and the relationship between visual memory and eye movements. Visual long-term memory is then reviewed from several different perspectives, including memory for natural scenes, the relationship between visual memory and object recognition, and associative learning. The final chapters discuss the neural mechanisms of visual memory and neuropsychological deficits in visual memory. This book is a comprehensive guide to visual memory research that will be a valuable resource for both students and professionals.

Download New Research on Short-term Memory Book in PDF, ePub and Kindle
Short-term memory, sometimes referred to as "primary", "working" or "active" memory, is said to hold a small amount of information for about 20 seconds. Estimates of short-term memory capacity vary -- from about 3 or 4 elements (i.e., words, digits, or letters) to about 9 elements: a commonly cited capacity is 7±2 elements. In contrast, long-term memory indefinitely stores a seemingly unlimited amount of information. Short-term memory can be described as the capacity (or capacities) for holding in mind, in an active, highly available state, a small amount of information. The information held in short-term memory may be: recently processed sensory input; items recently retrieved from long-term memory; or the result of recent mental processing, although that is more generally related to the concept of working memory. This book presents the latest research in the field from around the world.

Download Discovering the Brain Book in PDF, ePub and Kindle
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."

“This book will be a valuable resource for psychologists and educators who work with children or adolescents who are having difficulties with memory and learning. Translating theory and research into practice is a talent that Dr. Dehn possesses and we will benefit from his professional skills.” — From the Foreword by Daniel C. Miller, PhD, ABPP, ABSNP, NCSP AN INDISPENSABLE GUIDE THAT EXAMINES THE EFFECT OF LONG-TERM MEMORY FUNCTIONS ON CHILDREN’S LEARNING Long-Term Memory Problems in Children and Adolescents: Assessment, Intervention, and Effective Instruction is the first book of its kind for psychologists, school psychologists, and special education teachers who need an overview of long-term memory as it relates to learning and education. It presents the best practices for assessing long-term memory functions, as well as selecting and using evidence-based instructional practices with memory-impaired students. This useful and timely guide bridges theory and practice to provide professional guidance with coverage of: Risk factors that can lead to long-term memory impairments How long-term memory relates to other types of memory The subcomponents and processes of long-term memory and how they relate to academic achievement What is known about the neuroanatomy of how memories are formed The developmental trajectory of memory and learning Common types of memory dysfunction Memory assessment strategies, interventions for memory problems, and instructional practices that support memory Author Milton Dehn draws on his extensive experience as a trainer and workshop presenter, school psychologist, and educator to present both the theory and research on long-term memory in children and adolescents in this book. Specific, step-by-step guidance and hands-on case studies enable professionals to identify how memory can be assessed as well as the interventions that can be linked to the results of the assessment.

Download Perceptual Learning and Visual Short-term Memory Book in PDF, ePub and Kindle
Visual short-term memory (VSTM) is commonly perceived as a temporary buffer into which information is moved for retention across relatively short intervals. Guided by work on the "standard model" of working memory, these buffers are assumed to reside in modality-specific areas of the prefrontal cortex (PFC). Recent converging evidence has begun to call these conventional views into question, with a growing consensus that working memory is the emergent result of attention-guided activity across many areas of the brain. This "emergent-property" view suggests that working memory is sustained in part by the very same sensory areas involved in encoding external input. If visual short-term memory is represented and maintained on the same neural populations involved in common perceptual tasks as evidence suggests, we might expect possible interactions. The current thesis describes a series of experiments designed to build a detailed profile of these interactions. In Chapter 2 we establish the utility of using visual aftereffects as investigative tools in two behavioral experiments. In the first experiment we measure the magnitude of static and dynamic motion aftereffects before and after perceptual learning on a motion discrimination task using identical stimuli. Our results indicate that learning does not affect the duration of the aftereffects, strongly suggesting that improvements in discrimination are not mediated by changes in the underlying perceptual representations of the stimuli. Rather, our evidence supports the view that practice changes the relative contributions of perceptual outputs to decision-making areas. A second experiment rules out a competing explanation in which the locus of learning does not share enough overlap with the neural populations responsible for the observed aftereffects. Next, in Chapter 3 we demonstrate the efficacy of analyzing multivariate response data over traditional reliance on accuracy or response time alone. We apply the diffusion model (DM) to accuracy and response time distributions on data from two perceptual learning experiments. Results reveal that practice-induced improvements in motion direction discrimination arise from the combination of stimulus-specific improvements in the quality of sensory information entering decision areas, and non-specific gains in the timing of decision-making processes. Following this, in Chapter 4 we leverage the methodological gains of the previous results to test the hypothesis that the contents of VSTM can influence the perception of stimuli during the memory retention interval. We use a dual-task design to test the effect of VSTM on perception. Results suggest that orientation information in memory has a repulsive effect on the perception of subsequently presented orientations, not unlike tilt aftereffects. Further DM analysis confirms that our results are perceptual in nature and do not arise from artifacts in response time shifts. Finally, in Chapter 5 we describe an experiment designed to test if the interactions observed in Chapter 4 share the same neural mechanism as memory masking, and what, if any, effect practice has on these two forms of interference. An asymmetrical effect due to memory-stimulus similarity, as well as contrasting effects due to training on the two sources of interference strongly indicate the involvement of two separate processes. Taken together, this collection of studies highlights the existence of another form of VSTM-perception entanglement that is complementary to memory masking, but behaves much differently, particularly under the influence of practice. The results indicate that VSTM and perception interact in systematic ways that are critical to understand, most notably in laboratory settings where the effects can disrupt the subtle differences upon which observers must make decisions. A novel model is proposed that parsimoniously reconciles observed patterns of perceptual learning, as well as the apparently disparate forms of interactions measured throughout. Collectively, the present work supports the emergent-property hypothesis of working memory, as well as a revised version of the standard model.Less
