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?
Book Synopsis Crossmodal Attention Applied by : Charles Spence
Download or read book Crossmodal Attention Applied written by Charles Spence and published by Cambridge University Press. This book was released on 2020-09-10 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cognitive neuroscientists have started to uncover the neural substrates, systems, and mechanisms enabling us to prioritize the processing of certain sensory information over other, currently less-relevant, inputs. However, there is still a large gap between the knowledge generated in the laboratory and its application to real-life problems of attention as when, for example, interface operators are multi-tasking. In this Element, laboratory studies on crossmodal attention (both behavioural/psychophysical and cognitive neuroscience) are situated within the applied context of driving. We contrast the often idiosyncratic conditions favoured by much of the laboratory research, typically using a few popular paradigms involving simplified experimental conditions, with the noisy, multisensory, real-world environments filled with complex, intrinsically-meaningful stimuli. By drawing attention to the differences between basic and applied studies in the context of driving, we highlight a number of important issues and neglected areas of research as far as the study of crossmodal attention is concerned.
Book Synopsis Turning the Mind’s Eye Inward: The Interplay between Selective Attention and Working Memory by : Elger Abrahamse
Download or read book Turning the Mind’s Eye Inward: The Interplay between Selective Attention and Working Memory written by Elger Abrahamse and published by Frontiers Media SA. This book was released on 2016-01-21 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis The Role of Multisensory Integration in the Bottom-up and Top-down Control of Attentional Object Selection by : Pawel Jerzy Matusz
Download or read book The Role of Multisensory Integration in the Bottom-up and Top-down Control of Attentional Object Selection written by Pawel Jerzy Matusz and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective spatial attention and multisensory integration have been traditionally considered as separate domains in psychology and cognitive neuroscience. However, theoretical and methodological advancements in the last two decades have paved the way for studying different types of interactions between spatial attention and multisensory integration. In the present thesis, two types of such interactions are investigated. In the first part of the thesis, the role of audiovisual synchrony as a source of bottom-up bias in visual selection was investigated. In six out of seven experiments, a variant of the spatial cueing paradigm was used to compare attentional capture by visual and audiovisual distractors. In another experiment, single-frame search arrays were presented to investigate whether multisensory integration can bias spatial selection via salience-based mechanisms. Behavioural and electrophysiological results demonstrated that the ability of visual objects to capture attention was enhanced when they were accompanied by noninformative auditory signals. They also showed evidence for the bottom-up nature of these audiovisual enhancements of attentional capture by revealing that these enhancements occurred irrespective of the task-relevance of visual objects. In the second part of this thesis, four experiments are reported that investigated the spatial selection of audiovisual relative to visual objects and the guidance of their selection by bimodal object templates. Behavioural and ERP results demonstrated that the ability of task-irrelevant target-matching visual objects to capture attention was reduced during search for audiovisual as compared to purely visual targets, suggesting that bimodal search is guided by integrated audiovisual templates. However, the observation that unimodal targetmatching visual events retained some ability to capture attention indicates that bimodal search is controlled to some extent by modality-specific representations of task-relevant information. In summary, the present thesis has contributed to our knowledge of how attention is controlled in real-life environments by demonstrating that spatial selective attention can be biased towards bimodal objects via salience-driven as well as goal-based mechanisms.
Book Synopsis The New Handbook of Multisensory Processing by : Barry E. Stein
Download or read book The New Handbook of Multisensory Processing written by Barry E. Stein and published by MIT Press. This book was released on 2012-06-01 with total page 841 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.
Book Synopsis Music and the Functions of the Brain: Arousal, Emotions, and Pleasure by : Mark Reybrouck
Download or read book Music and the Functions of the Brain: Arousal, Emotions, and Pleasure written by Mark Reybrouck and published by Frontiers Media SA. This book was released on 2018-04-12 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Music impinges upon the body and the brain. As such, it has significant inductive power which relies both on innate dispositions and acquired mechanisms and competencies. The processes are partly autonomous and partly deliberate, and interrelations between several levels of processing are becoming clearer with accumulating new evidence. For instance, recent developments in neuroimaging techniques, have broadened the field by encompassing the study of cortical and subcortical processing of the music. The domain of musical emotions is a typical example with a major focus on the pleasure that can be derived from listening to music. Pleasure, however, is not the only emotion to be induced and the mechanisms behind its elicitation are far from understood. There are also mechanisms related to arousal and activation that are both less differentiated and at the same time more complex than the assumed mechanisms that trigger basic emotions. It is imperative, therefore, to investigate what pleasurable and mood-modifying effects music can have on human beings in real-time listening situations. This e-book is an attempt to answer these questions. Revolving around the specificity of music experience in terms of perception, emotional reactions, and aesthetic assessment, it presents new hypotheses, theoretical claims as well as new empirical data which contribute to a better understanding of the functions of the brain as related to musical experience.
Book Synopsis The Child as Musician by : Gary E. McPherson
Download or read book The Child as Musician written by Gary E. McPherson and published by Oxford University Press. This book was released on 2015-09-24 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of The Child as Musician: A Handbook of Musical Development celebrates the richness and diversity of the many different ways in which children can engage in and interact with music. It presents theory - both cutting edge and classic - in an accessible way for readers by surveying research concerned with the development and acquisition of musical skills. The focus is on musical development from conception to late adolescences, although the bulk of the coverage concentrates on the period when children are able to begin formal music instruction (from around age 3) until the final year of formal schooling (around age 18). There are many conceptions of how musical development might take place, just as there are for other disciplines and areas of human potential. Consequently, the publication highlights the diversity in current literature dealing with how we think about and conceptualise children's musical development. Each of the authors has searched for a better and more effective way to explain in their own words and according to their own perspective, the remarkable ways in which children engage with music. In the field of educational psychology there are a number of publications that survey the issues surrounding child and adolescent development. Some of the more innovative present research and theories, and their educational implications, in a style that stresses the fundamental interplay among the biological, environmental, social and cultural influences at each stage of a child's development. Until now, no similar overview has existed for child and adolescent development in the field of music. The Child as Musician addresses this imbalance, and is essential for those in the fields of child development, music education, and music cognition.
Download or read book Perception written by Nicola Bruno and published by Oxford University Press. This book was released on 2018-07-26 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The way that we interact with the environment on a daily basis is inherently multisensory. Even a simple task such as judging the location of a light in a dark room depends not only on vision but also on proprioceptive cues about the position of our body in space. The way that we experience food can be influenced not just by taste and smell, but by visual and auditory cues. Perception: A multisensory perspective adopts a multisensory approach to understanding perception. Rather than discussing each sense separately, this book defines perception as intrinsically multisensory from the start and examines multisensory interactions as the key process behind how we perceive our own body, control its movements, and perceive and recognise objects, space, and time. But the book delves even deeper. It discusses multisensory processing in conditions such as synaesthesia. It addresses attention and the role of multisensory processing in learning. By focussing on these domains, the authors highlight and identify general principles in the field of perception study and introduce models, experimental methods and pathologies that will be of interest to all those studying within the field of perception. The authors also illustrate applications that will be of interest to professionals whose work takes multisensory processing into account. As an introduction to the topic of multisensory perception, Perception: A multisensory perspective will be essential reading for students, from advanced undergraduate level through to postgraduate level in psychology, philosophy, and neuroscience. Those studying physiotherapy and neurological rehabilitation, human-computer interface development, or the design of products or services will also find this book of interest.

Book Synopsis The Neural Bases of Multisensory Processes by : Micah M. Murray
Download or read book The Neural Bases of Multisensory Processes written by Micah M. Murray and published by CRC Press. This book was released on 2011-08-25 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

Book Synopsis Biased Cognitions & Social Anxiety: Building a Global Framework for Integrating Cognitive, Behavioral, and Neural Processes by : Alexandre Heeren
Download or read book Biased Cognitions & Social Anxiety: Building a Global Framework for Integrating Cognitive, Behavioral, and Neural Processes written by Alexandre Heeren and published by Frontiers Media SA. This book was released on 2015-03-05 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social anxiety (SA) is a common and incapacitating disorder that has been associated with seriously impaired career, academic, and general social functioning. Regarding epidemiological data, SA has a lifetime prevalence of 12.1% and is the fourth most common psychopathological disorder (Kessler et al., 2005). At a fundamental point of view, the most prominent cognitive models of SA posit that biased cognitions contribute to the development and maintenance of the disorder (e.g., Clark & Wells, 1995; Rapee & Heimberg, 1997). Over the last decades, a large body of research has provided evidence that individuals suffering from SA exhibit such biased cognitions at the level of visual attention, memory of social encounters, interpretation of social events, and in judgment of social cues. Such biased cognitions in SA has been studied in different ways within cognitive psychology, behavioral psychology, clinical psychology, and cognitive neuroscience over the last few decades, yet, integrative approaches for channeling all information into a unified account of biased cognitions in SA has not been presented so far. The present Research Topic aims to bring together theses different ways, and to highlight findings and methods which can unify research across these areas. In particular, this Research Topic aims to advance the current theoretical models of SA and set the stage for future developments of the field by clarifying and linking theoretical concepts across disciplines.
Book Synopsis Traumatic Brain Injury by : Mark J. Ashley
Download or read book Traumatic Brain Injury written by Mark J. Ashley and published by CRC Press. This book was released on 2017-07-28 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth edition of this text constitutes a continuation of 20 years of coverage of traumatic brain injury, and broadens the discussion of acquired brain injury. Within TBI, the paradigm shift from an injury occurring at a point in time to a disease entity of a chronic nature is changing the discussion of diagnosis, management, treatment and outcome assessment. Disease specification that differentiates TBIs by the mechanism of injury, the exact nature of the injury, the extent of injury, presence of co-morbidities and their exact nature, gender, age, race, and genome are emerging as crucial. Disease differentiation has impacted diagnosis, treatment and outcome.
Book Synopsis Multisensory Integration: Brain, Body and the World by : Magda L. Dumitru
Download or read book Multisensory Integration: Brain, Body and the World written by Magda L. Dumitru and published by Frontiers Media SA. This book was released on 2016-03-22 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral, language, and reasoning are expressions of neural functions par excellence, as the brain must draw on sensory modalities to gather information on the rest of the body and on the outer world. Cortical areas processing the identity and location of the sensory inputs were once thought to be organized, with some branches dedicated to complex features. Yet current studies have uncovered synergistic effects at early-stage cognitions as well as higher-level association areas. A less hierarchical functional architecture of the brain has emerged such that, irrespective of sensory modality, inputs are assigned to the best suited cortical substrate.
