Book Description
Optimal performance of everyday tasks like driving depend critically on both the ability to store and retrieve small amounts of information in the short term, and the ability to selectively find and process relevant objects while preventing distraction. These two abilities have traditionally been viewed as distinct processes in human cognition, however research now demonstrates significant overlap between the constructs of working memory and selective attention. Previous work has established a role for working memory resources in the successful control of attention, however there are many processes underlying successful attentional control, and affecting any one of them would produce the pattern of results that have been observed. In this thesis we used behavioural and electroencephalographic evidence to investigate working memory and selective attention. We aim to provide a more detailed understanding of the processes underlying the relationship between these two constructs. Study 1 provided systematic documentation of the effect that distractor objects have on performance in a traditional working memory task, as well as the relationship between these effects and individual differences in working memory capacity. Study 2 used lateralized event-related potentials to measure dissociable components related to target selection, distractor capture, and distractor disengagement while working memory load was manipulated. Study 2 used electroencephalographic measures of attention processes to show that increased working memory load has a specific effect on neural indices of distractor disengagement. Study 3 used a similar paradigm to Study 2 to show that the presence of irrelevant objects during working memory encoding leads to impairments in performance and modulation of the neural response to targets in a concurrent visual search task. Together, our results provide greater specificity of the relationship between attention and working memory while demonstrating the utility of lateralized ERPs in providing dissociable measures of specific attentional sub-processes. This provides a promising tool for future research which investigates the relationship between working memory and selective attention.

Book Description
The Development of Memory in Infancy and Childhood provides a thorough update and expansion of the previous edition and offers new research on significant themes and ideas that have emerged in the past decade such as the cognitive neuroscience of memory development, autobiographical memory and infantile amnesia, and the cognitive and social factors that underlie memory for events. In this volume, Courage and Cowan bring together leading international experts to review the current state of the science of memory development in their own research areas. They note questions of theory and basic science addressed in their research, highlight the real-world applications of those findings, and propose an agenda for future research. The book also considers the implications of their work for the development of atypical children, specifically, how these new findings might be adapted to enrich the lives of those children and to inform and validate our current expectations of individual differences in the development of typical children. The first of three groups of chapters focuses on basic neurobiological, perceptual, and cognitive processes that underlie memory and its development (i.e., encoding, consolidation and storage, retrieval). The second group focuses primarily on the social, contextual, and cultural factors that enable, shape, and mediate these basic processes, while the rest of the chapters focus on practical applications of this knowledge to real-world settings and issues. The book provides a new look at memory development, including new topics such as spatial representation and spatial working, prospective memory, false memories, and memory and culture. This classic yet contemporary volume will appeal to senior undergraduate and graduate students of developmental and cognitive psychology, as well as to developmental psychologists who want a compendium of key topics in memory development.

Book Description
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.

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
Historically, cognitive sciences have considered selective attention and working memory as largely separated cognitive functions. That is, selective attention as a concept is typically reserved for the processes that allow for the prioritization of specific sensory input, while working memory entails more central structures for maintaining (and operating on) temporary mental representations. However, over the last decades various observations have been reported that question such sharp distinction. Most importantly, information stored in working memory has been shown to modulate selective attention processing – and vice versa. At the theoretical level, these observations are paralleled by an increasingly dominant focus on working memory as (involving) the attended part of long-term memory, with some positions considering that working memory is equivalent to selective attention turned to long-term memory representations – or internal selective attention. This questions the existence of working memory as a dedicated cognitive function and raises the need for integrative accounts of working memory and attention. The next step will be to explore the precise implications of attentional accounts of WM for the understanding of specific aspects and characteristics of WM, such as serial order processing, its modality-specificity, its capacity limitations, its relation with executive functions, as well as the nature of attentional mechanisms involved. This research topic in Frontiers in Human Neuroscience aims at bringing together the latest insights and findings about the interplay between working memory and selective attention.

Book Description
One current model of visual selective attention proposes two mechanisms that work together to achieve processing of important information: facilitation - which controls the processing of relevant target stimuli - and suppression - which works to filter out irrelevant distracting stimuli. While facilitation is seen in all ages, previous research indicates suppression develops later in childhood (Plebanek & Sloutsky 2017; 2019; Wong-Kee-You et al., 2019). One theory regarding the development of selective attention is that it is linked to the development of working memory - given the functional and neural overlap between the two processes (Downing, 2000; LaBar et al., 2019). This study investigated the developmental timeline of suppression using electrophysiological methods to create a quantitative physiological measure of facilitation and suppression during visual selective attention using the P1/N1 event related potential (ERP) components for 24 adults and 12 children (8-12 years-old). Our results reveal a suppression effect of the N1 component for adults, but not for children; suggesting that suppression may not develop before the age of 12. Additionally, we discovered children reach adult levels for visual working memory capacity between the ages of 10-12 years-old; and that for children only, visual working memory capacity has a significant interaction with attention ability. This indicates that working memory capacity develops earlier and may influence later development of selective attention skills - including suppression. Understanding the development of attention and working memory will provide useful information in creating effective classroom management strategies and enhancing the focus of task-related information to foster childhood learning.

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.
