Available in PDF, EPUB and Kindle. Book excerpt: Selective attention allows us to filter out irrelevant sensory information in the environment and focus neural resources on information relevant to our current goals, while being able to flexibly shift our focus to potentially rewarding or harmful stimuli. Functional brain imaging studies have identified networks of broadly distributed brain regions that are recruited during goal-driven attention (i.e. based on internal expectations or goals) and/or stimulus-driven attention (i.e. driven by salient or unexpected stimuli); however, the dynamics by which these networks enable selection of attended sensory information are not well understood due to the low temporal resolution of functional neuroimaging. Here, we first used functional MRI to localize attention-related and other task-relevant and -irrelevant brain networks in human epileptic subjects, prior to localization of their seizure foci using electrocorticography (ECoG), electrodes placed directly on the cortical surface. We subsequently recorded cortical physiology from the ECoG electrodes during a spatial attention task, involving both goal-driven and stimulus-driven attention, and co-registered electrode positions with the fMRI-defined networks to study network-specific dynamics during these two processes. We found that low frequency local field potential (LFP) oscillations, which are thought to reflect fluctuations in local neuronal excitability, became selectively phase modulated over task-relevant brain regions/networks during the same task epochs in which they are recruited in fMRI. This mechanism may alter the excitability of task-relevant regions or the effective connectivity between them to enable selective neural processing of attended stimuli. Furthermore, different attention processes (holding vs. shifting attention) were associated with phase modulations at different frequencies, possibly to multiplex different cognitive processes and minimize unnecessary cross talk between unrelated neuronal populations.
Download or read book Attention and Time written by Kia Nobre and published by . This book was released on 2010 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our ability to attend selectively to our surroundings - taking notice of the things that matter, and ignoring those that don't - is crucial if we are to negotiate the world around us in an efficient manner. Several aspects of the temporal dimension turn out to be critical in determining how we can put together and select the events that are important to us as they themselves unfold over time. For example, we often miss events that happen while we are occupied perceiving or responding to another stimulus. On the other hand, temporal regularity between events can also greatly improve our perception. In addition, our perception of the passage of time itself can also be distorted as while we are performing actions or paying attention to different aspects of the environment. Surprisingly, this fascinating and fundamental interplay between ' attention' and 'time' has been relatively neglected in the psychology and neuroscience literatures until very recently. Attention & Time is the first book to address this foundational topic, bringing together several intriguing and hitherto fragmented findings into a compelling and cohesive field of enquiry. The book contains thirty-one critical-review chapters from internationally recognised experts in the field, carefully organised into three stand-alone, yet extensively cross-referenced, themed sections. Each section focuses on distinct ways in which attention and time influence one another. These sections, each encompassing a range of methodologies from classical cognitive psychology to single-cell neurophysiology, provide functionally unifying frameworks to help guide the reader through the many various experimental and theoretical approaches adopted. Section 1 considers variations of attention across time, and explores how attentional allocation is limited by very short or very long intervals of time. Section 2 describes several types of temporal illusion, illustrating how attention can modulate the perception of the passage of time itself. "A watched pot never boils" and, conversely, "time flies when you're having fun" nicely capture the experimental observation that the degree of attention allocated to stimulus timing contributes to its subjective duration. Finally, Section 3 examines how attention can be directed in time, to predictable or expected moments in time, so as to optimise behaviour. Bringing conceptually discrete, yet functionally related, fields of temporal attention research together within a single volume, this book provides a comprehensive overview that will be of value to the interested novice in cognitive neuroscience, whilst also inspiring experts in the field to make, perhaps previously overlooked, links with their own field of research.

Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, there have been enormous advances in our understanding of the neural mechanisms of selective attention at the network as well as the cellular level. The Oxford Handbook of Attention brings together the different research areas that constitute contemporary attention research into one comprehensive and authoritative volume. In 40 chapters, it covers the most important aspects of attention research from the areas of cognitive psychology, neuropsychology, human and animal neuroscience, computational modelling, and philosophy. The book is divided into 4 main sections. Following an introduction from Michael Posner, the books starts by looking at theoretical models of attention. The next two sections are dedicated to spatial attention and non-spatial attention respectively. Within section 4, the authors consider the interactions between attention and other psychological domains. The last two sections focus on attention-related disorders, and finally, on computational models of attention. Aimed at both scholars and students, the Oxford Handbook of Attention provides a concise and state-of-the-art review of the current literature in this field.

Download or read book Cognitive Electrophysiology of Attention written by George R. Mangun and published by Academic Press. This book was released on 2013-08-31 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cognitive Electrophysiology of Attention explores the fundamental mechanisms of attention and related cognitive functions from cognitive neuroscience perspectives. Attention is an essential cognitive ability that enables humans to process and act upon relevant information while ignoring distracting information, and the capacity to focus attention is at the core of mental functioning. Understanding the neural bases of human attention remains a key challenge for neuroscientists and psychologists, and is essential for translational efforts to treat attentional deficits in a variety of neurological and psychiatric disorders. Cognitive electrophysiology is at the center of a multidisciplinary approach that involves the efforts of psychologists, neuroscientists, neuropsychologists, psychiatrists, and neurologists to identify basic brain mechanisms and develop translational approaches to improve mental health. This edited volume is authored by leading investigators in the field and discusses methods focused on electrophysiological recordings in humans, including electroencephalography (EEG) and event-related potential (ERP) methods, and also incorporates evidence from functional magnetic resonance imaging (fMRI). Cognitive Electrophysiology of Attention illuminates specific models about attentional mechanisms in vision, audition, multisensory integration, memory, and semantic processing in humans. Provides an exhaustive overview of attention processes, going from normal functioning to the pathological, and using a combination of methodological tools An important reference for electrophysiology researchers looking at underlying attention processes rather than the methods themselves Enables researchers across a broad range of cognitive-process and methodological specialties to stay current on particular hypotheses, findings, and methods Edited and authored by the worldwide leaders in the field, affording the broadest, most expert coverage available

Download or read book The Temporal Dynamics of Cognitive Processing written by Timothy Michael Ellmore and published by Frontiers Media SA. This book was released on 2016-07-26 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: From our ability to attend to many stimuli occurring in rapid succession to the transformation of memories during a night of sleep, cognition occurs over widely varying time scales spanning milliseconds to days and beyond. Cognitive processing is often influenced by several behavioral variables as well as nonlinear interactions between multiple neural systems. This frequently produces unpredictable patterns of behavior and makes understanding the underlying temporal factors influencing cognition a fruitful area of hypothesis development and scientific inquiry. Across two reviews, a perspective, and twelve original research articles covering the domains of learning, memory, attention, cognitive control, and social decision making this research topic sheds new light on the temporal dynamics of cognitive processing.

Download or read book Time Will Tell written by Mari Riess Jones and published by Oxford University Press, USA. This book was released on 2019 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention is a central concept in psychology. The term 'attention' itself has persisted, even though it implies a static, insulated capacity that we use when it is necessary to focus upon some relevant or stimulating event. Riess Jones presents a different way of thinking about attention; one that describes it as a continuous activity that is based on energy fluctuating in time. A majority of attention research fails to examine influence of event time structure (i.e., a speech utterance) on listeners' moment-to-moment attending. General research ignores listeners endowed with innate, as well as acquired, temporal biases. Here, attending is portrayed as a dynamic interaction of an individual within his or her surroundings. Importantly, this interaction involves synchronicity between an attender and external events. This emphasis on time and synchronicity distinguishes the author's theory, called Dynamic Attending Theory (DAT), from other approaches to attending which characterize attention metaphorically as a filter, resource pool, spotlight, and so on. Recent research from neuroscience has lent support to Riess Jones' theory, and the goal of this book is to bring this new research as well as her own to the wide audience of psychologists interested in attention more broadly.
Download or read book The Breadth of Visual Attention written by Stephanie C. Goodhew and published by Cambridge University Press. This book was released on 2020-06-18 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans can focus their attention narrowly (e.g., to read this text) or broadly (e.g., to determine which way a large crowd of people are moving). This Element comprehensively considers attentional breadth. Section 1 introduces the concept of attentional breadth, while Section 2 considers measures of attentional breadth. In particular, this section provides a critical discussion of the types of psychometric evidence which should be sought to establish the validity of measures of attentional breadth and reviews the available evidence through this lens. Section 3 considers the visual task performance consequences of attentional breadth, including prescribing several key methodological criteria that studies that manipulate attentional breadth need to meet, as well as a discussion of relevant theories and avenues for future theoretical development. Section 4 discusses the utility of the exogenous-endogenous distinction from covert shifts of attention for understanding the performance consequences of attentional breadth. Finally, Section 5 provides concluding remarks.
Download or read book The Evolution of Rhythm Cognition Timing in Music and Speech written by Andrea Ravignani and published by Frontiers Media SA. This book was released on 2018-07-24 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human speech and music share a number of similarities and differences. One of the closest similarities is their temporal nature as both (i) develop over time, (ii) form sequences of temporal intervals, possibly differing in duration and acoustical marking by different spectral properties, which are perceived as a rhythm, and (iii) generate metrical expectations. Human brains are particularly efficient in perceiving, producing, and processing fine rhythmic information in music and speech. However a number of critical questions remain to be answered: Where does this human sensitivity for rhythm arise? How did rhythm cognition develop in human evolution? How did environmental rhythms affect the evolution of brain rhythms? Which rhythm-specific neural circuits are shared between speech and music, or even with other domains? Evolutionary processes’ long time scales often prevent direct observation: understanding the psychology of rhythm and its evolution requires a close-fitting integration of different perspectives. First, empirical observations of music and speech in the field are contrasted and generate testable hypotheses. Experiments exploring linguistic and musical rhythm are performed across sensory modalities, ages, and animal species to address questions about domain-specificity, development, and an evolutionary path of rhythm. Finally, experimental insights are integrated via synthetic modeling, generating testable predictions about brain oscillations underlying rhythm cognition and its evolution. Our understanding of the cognitive, neurobiological, and evolutionary bases of rhythm is rapidly increasing. However, researchers in different fields often work on parallel, potentially converging strands with little mutual awareness. This research topic builds a bridge across several disciplines, focusing on the cognitive neuroscience of rhythm as an evolutionary process. It includes contributions encompassing, although not limited to: (1) developmental and comparative studies of rhythm (e.g. critical acquisition periods, innateness); (2) evidence of rhythmic behavior in other species, both spontaneous and in controlled experiments; (3) comparisons of rhythm processing in music and speech (e.g. behavioral experiments, systems neuroscience perspectives on music-speech networks); (4) evidence on rhythm processing across modalities and domains; (5) studies on rhythm in interaction and context (social, affective, etc.); (6) mathematical and computational (e.g. connectionist, symbolic) models of “rhythmicity” as an evolved behavior.

Download or read book Neuroscience driven Visual Representation written by Teng Li and published by Frontiers Media SA. This book was released on 2024-08-14 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual representation learning enables computers or systems to simulate the function of retinas, optic nerves, and visual cortex in the human brain, and derive meaningful information from digital images, videos, and other visual inputs. To learn the effective presentation of visual data is essential for many computer vision and artificial intelligence applications ranging from energy and utilities to manufacturing and automotive. Current popular deep learning-based visual representation learning methods do not fully consider the nature of the biological visual nervous system and are lack in interpretability. To solve visual representation well, the integration of psychological or neuroscientific approaches is required to enhance the cognition of visual data.
Download or read book A Matter of Bottom Up or Top Down Processes The Role of Attention in Multisensory Integration written by Jess Hartcher-O'Brien and published by Frontiers Media SA. This book was released on 2017-07-04 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of information from various sensory modalities influences behaviour. It can induce behavioural benefits such as faster reaction times and enhanced detection of noisy signals but may also produce illusions, all of which have been characterized by specific neuronal signatures. Yet, while these effects of multisensory integration are largely accepted, the role of attention in this process is still the object of intense debate. On the one hand, it has been suggested that attention may guide multisensory integration in a top-down fashion by selection of specific inputs to be integrated out of the plethora of information in our environment. On the other hand, there is evidence that integration could occur in a bottom-up manner, based on temporal and spatial correlations, and outside the focus of attention. An extreme example is the multisensory enhancement of neural responses in anesthetised animals. Attention itself is not a unitary construct, and may refer to a range of different selection mechanisms. Therefore, the interplay between attention and multisensory integration can take many forms which explain, in part, the diversity of findings and the disputes in the literature. The goal of this Research Topic is to help clarify the picture by trying to answer the following questions from various perspectives: Under which circumstances does multisensory integration take place without attention?, and, When does attention determine the fate of multisensory integration?
Download or read book Attentional Selection written by Jan Theeuwes and published by Cambridge University Press. This book was released on 2020-09-03 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Element, a framework is proposed in which it is assumed that visual selection is the result of the interaction between top-down, bottom-up and selection-history factors. The Element discusses top-down attentional engagement and suppression, bottom-up selection by abrupt onsets and static singletons as well as lingering biases due to selection-history entailing priming, reward and statistical learning. We present an integrated framework in which biased competition among these three factors drives attention in a winner-take-all-fashion. We speculate which brain areas are likely to be involved and how signals representing these three factors feed into the priority map which ultimately determines selection.
