Download or read book Working Memory Capacity written by Nelson Cowan and published by Psychology Press. This book was released on 2016-04-14 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Competition and Control during Working Memory written by Anastasia Kiyonaga and published by Cambridge University Press. This book was released on 2020-11-12 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Working memory and perceptual attention are related functions, engaging many similar mechanisms and brain regions. As a consequence, behavioral and neural measures often reveal competition between working memory and attention demands. Yet there remains widespread debate about how working memory operates, and whether it truly shares processes and representations with attention. This Element will examine local-level representational properties to illuminate the storage format of working memory content, as well as systems-level and brain network communication properties to illuminate the attentional processes that control working memory. The Element will integrate both cognitive and neuroscientific accounts, describing shared substrates for working memory and perceptual attention, in a multi-level network architecture that provides robustness to disruptions and allows flexible attentional control in line with goals.

Download or read book Attentional Control Processing in Working Memory written by Margot Diane Sullivan and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective attention is required for working memory and is theorized to underlie the process of selecting between two active languages in bilinguals. Studies of working memory performance and bilingualism have produced divergent results and neural investigations are still in the early stages. The purpose of the current series of studies using older and younger bilingual and monolingual adults was to examine working memory processing by manipulating attentional control demands and task domain. It was hypothesized that bilinguals in both age groups will outperform monolinguals when verbal demands are low and when attentional control demands are high. Study 1 included behavioural tasks that varied by domain and attentional control. Study 2 addressed these factors by examining the neural correlates of maintenance and updating using ERPs. A third analytic approach using partial least squares (PLS) analysis was performed on the recognition data from Study 2 to assess contrasting group patterns of amplitude and signal variability using multiscale entropy (MSE). Bilingual performance was poorer than monolingual when the task involved verbal production, but bilinguals outperformed monolinguals when the task involved nonverbal interference resolution. P3 amplitude was largely impacted by attentional demands and aging, whereas language group differences were limited. Extensive language and age group differences emerged once whole brain neural patterns were examined. Bilingual older adults displayed a neural signature similar to younger adults for both amplitude and MSE measures. Older adult monolinguals did not show these patterns and required additional frontal resources for the difficult spatial update condition. Younger bilinguals showed long-range, frontal-parietal MSE patterns for updating in working memory. These results are consistent with the interpretation of brain functional reorganization for bilingual working memory processing and may represent adaptations to a top-down attentional control mechanism.
Download or read book Attentional Capture written by Bradley S. Gibson and published by . This book was released on 2008 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The notion that certain mental or physical events can capture attention has been one of the most enduring topics in the study of attention owing to the importance of understanding how goal-directed and stimulus-driven processes interact in perception and cognition. Despite the clear theoretical and applied importance of attentional capture, a broad survey of this field suggests that the term "capture" means different things to different people. In some cases, it refers to covert shifts of spatial attention, in others involuntary saccades, and in still others general disruption of processing by irrelevant stimuli. The properties that elicit "capture" can also range from abruptly onset or moving lights, to discontinuities in textures, to unexpected tones, to emotionally valenced words or pictures, to directional signs and symbols. Attentional capture has been explored in both the spatial and temporal domains as well as the visual and auditory modalities. There are also a number of different theoretical perspectives on the mechanisms underlying "capture" (both functional and neurophysiological) and the level of cognitive control over capture. This special issue provides a sampling of the diversity of approaches, domains, and theoretical perspectives that currently exist in the study of attentional capture. Together, these contributions should help evaluate the degree to which attentional capture represents a unitary construct that reflects fundamental theoretical principles and mechanisms of the mind.
Download or read book Variation in Working Memory written by Andrew Conway and published by Oxford University Press. This book was released on 2008-02-13 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Attention written by Robert W Proctor, PhD and published by . This book was released on 2022-11-08 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text presents a comprehensive and accessible overview of the science of attention, conveying its central findings and applications to real-world issues, including its relationship with technology, learning, and memory. The study of attention is a core area of psychology that is particularly relevant today, given the ever-increasing demands on our mental workload. This book conveys the essential issues in attention research, showing how theory and research co-evolve. The authors use an interdisciplinary information-processing framework that draws from cognitive psychology and neuroscience. Each chapter reviews a specific type of attention and related cognitive processes, including auditory and visual selective attention, attentional control and inhibition, divided attention and multitasking, sensory and working memory, and memory consolidation and information retrieval. Feature boxes help readers translate key research findings into real-world applications. A special focus is the relationship between attention and modern technology, for example in processing multisensory input in virtual and online environments, and in situations such as air traffic control, piloting, and driving, where situation awareness is crucial. Various pathologies that affect attention are also reviewed, including ADHD, autism-spectrum disorders, dementia, and head injuries.
Download or read book Working Memory and Human Cognition written by John T. E. Richardson and published by Oxford University Press, USA. This book was released on 1996 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Inhibition Attentional Control and Causes of Forgetting in Working Memory a Formal Approach written by Odir Antonio Rodriguez-Villagra and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many cognitive activities, the temporary maintenance and manipulation of mental objects is a necessary step in order to reach a cognitive goal. Working memory has been regarded as the process responsible for those cognitive activities. This thesis addresses the question: what limits working-memory capacity (WMC)? A question that still remains controversial (Barrouillet & Camos, 2009; Lewandowsky, Oberauer, & Brown, 2009). This study attempted to answer this question by proposing that the dynamics between the causes of forgetting and the processes helping the maintenance, and the manipulation of the memoranda are the key aspects in understanding the limits of WMC. Chapter 1 introduced key constructs and the strategy to examine the dynamics between inhibition, attentional control, and the causes of forgetting in working memory. The study in Chapter 2 tested the performance of children, young adults, and old adults in a working-memory updating-task with two conditions: one condition included go steps and the other condition included go, and no-go steps. The interference model (IM; Oberauer & Kliegl, 2006), a model proposing interference-related mechanisms as the main cause of forgetting was used to simultaneously fit the data of these age groups. In addition to the interference-related parameters reflecting interference by feature overwriting and interference by confusion, and in addition to the parameters reflecting the speed of processing, the study included a new parameter that captured the time for switching between go steps and no-go steps. The study indicated that children and young adults were less susceptible than old adults to interference by feature overwriting; children were the most susceptible to interference by confusion, followed by old adults and then by young adults; young adults presented the higher rate of processing, followed by children and then by old adults; and young adults were the fastest group switching from go steps to no-go steps. Chapter 3 examined the dynamics between causes of forgetting and the inhibition of a prepotent response in the context of three formal models of the limits of WMC: A resources model, a decay-based model, and three versions of the IM. The resources model was built on the assumption that a limited and shared source of activation for the maintenance and manipulation of the objects underlies the limits of WMC. The decay model assumes that memory traces of the working-memory objects decay over time if they are not reactivated via different mechanisms of maintenance. The IM, already described, proposes that interference-related mechanisms explain the limits of WMC. In two experiments and in a reanalysis of data of the second experiment, one version of the IM received more statistical support from the data. This version of the IM proposes that interference by feature overwriting and interference by confusion are the main factors underlying the limits of WMC. In addition, the model suggests that experimental conditions involving the inhibition of a prepotent response reduce the speed of processing and promotes the involuntary activation of irrelevant information in working memory. Chapter 4 summed up Chapter 2 and 3 and discussed their findings and presented how this thesis has provided evidence of interference-related mechanisms as the main cause of forgetting, and it has attempted to clarify the role of inhibition and attentional control in working memory. With the implementation of formal models and experimental manipulations in the framework of nonlinear mixed models the data offered explanations of causes of forgetting and the role of inhibition in WMC at different levels: developmental effects, aging effects, effects related to experimental manipulations and individual differences in these effects. Thus, the present approach afforded a comprehensive view of a large number of factors limiting WMC

Download or read book Visual Attention Related Processing written by Andrea Tales and published by MDPI. This book was released on 2021-08-30 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual attention is essential for environmental interactions, but our ability to respond to stimuli gradually declines across the lifespan, and such deficits are even more pronounced in various states of cognitive impairment. Examining the integrity of related components, from elements of attention capture to executive control, will improve our understanding of related declines by helping to explain behavioural and neural effects, which will ultimately contribute towards our knowledge of the extent of dysfunctional attention processes and their impact upon everyday life. Accordingly, this Special Issue represents a body of literature that fundamentally advances insights into visual attention processing, featuring studies spanning healthy ageing, mild cognitive impairment, and dementia
