To interact with the environment, an individual must code, store, and translate spatial information into the appropriate motor commands for achieving an outcome. Working from this premise, Vision and Goal-Directed Movement: Neurobehavioral Perspectives discusses how visual perception, attention, and memory are linked to the processes of movement preparation and execution. With contributions from active researchers in movement science, Vision and Goal-Directed Movement presents the latest theories on the utilization of vision in goal-directed movement control. As a resource for motor control and motor learning researchers, students, educators, and clinicians, Vision and Goal-Directed Movement offers the following: • Comprehensive coverage of current behavior-based literature on the visual control of goal-directed movement • A systematic explication of the sensory and physiological processes and systems responsible for fast, accurate, and efficient performance • A solid foundation for further study of the sensory and neural systems responsible for precise goal-directed behavior • A discussion of how current research on vision and goal-directed movement can assist in creating efficient and safe work environments Using research informed by neural imaging and magnetic brain stimulation, this text provides readers with a better understanding of the neural foundations for goal-directed movement, illustrates the flexibility of the human visuomotor system, and discusses how regulation of movements depends on the learning and developmental history of the performer. It begins by reviewing the works of R.S. Woodworth and the influence of his theories on current research. The majority of the chapters in the first section of the book take a behavioral and process-oriented approach to exploring goal-directed movement. The text then explores the sensory and neural foundations for goal-directed action, including issues related to both pursuit and saccadic eye movements as well as discussion of the specialization of various cortical systems for the regulation of movement. Especially relevant to professionals and scientists concerned with skill instruction and rehabilitation, the final part of the text provides a review of recent research on how and why limb control changes occur with practice and development. In addition, Vision and Goal-Directed Movement considers how the research presented can maximize precision, efficiency, and safety in workspace design. Vision and Goal-Directed Movement: Neurobehavioral Perspectives adds a unique offering to the literature base for motor behavior, demonstrating how advances in both behavioral and neurophysiological methods can inform theories related to the biological systems contributing to skilled performance.

Book excerpt: Goal-directed movement is central to the relationship between brain and behavior in humans and other animals. This book presents a detailed investigation of the topic, one that integrates psychology and physiology. The author's account is based on a large body of experimental data from human and animal work, with particular emphasis on clinical cases. It probes such questions as: Are complex movements organized on the same mode as simple ones? How rigidly organized are coordinated actions like orienting or grasping? Where do visual feedback signals arise? The author's work takes into account the growing acceptance of the idea that movements are not directly dependent upon sensory events, but that they are governed by internal representations which are built according to specific, experimentally accessible rules.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains chapters derived from a N. A. T. O. Advanced Study Institute held in June 1983. As the director of this A. S. I. it was my hope that some of the e1ectrophysiologists could express the potentialities of their work for perceptual theory, and that some perceptionists could speculate on the underlying "units" of perception in a way that would engage the imagination of physio logists. The reader will have to be the judge of whether this was achieved, or whether such a psychophysiological inter1ingua is still overly idealistic. It is clear that after the revolution prec~pitated by Hube1 and Weisel in understanding of visual cortical neurons we still have only a foggy idea of the behavioral output of any particular species of cortical detector. It was therefore particularly unfortunate that two persons who have made great strides in correlating interesting facets of cat cortical physio logy with human psychophysics (Max Cynader and Martin Regan of Dalhousie University) were unable to attend this meeting. Never theless, a number of new and challenging ideas regarding both spatial perception and cortical mechanisms are represented in this volume, and it is hoped that the reader will remember not only the individual demonstrations but the critical questions posed by the apposition of the two different collections of experimental facts.

This book was released on 2008-11-21 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention is a key psychological construct in the understanding of human cognition, and the target of enormous efforts to elucidate its physiological mechanisms, as the wealth of literature—both primary and secondary—attests (for recent compilations see Itti, Rees, & Tsotsos, 2005; Paletta & Rome, 2008; Posner, 2004). But in addition to asking what attention actually is, decomposing and analyzing its varieties, or delimiting its neurobiological mechanisms and effects, in this volume we want to explore attention somewhat differently. We believe that a full-fledged theory of attention must consider its workings in the context of motivated, goal-directed, and environmentally constrained organisms. That attention is related to goal-directed behavior is not news. What the contri- tions to this volume do suggest, however, is the existence of fundamental links between attention and two key processes that are crucial for adapted conduct: go- directed behavior and cognitive control. Importantly, they show that these relations can be explored at multiple levels, including neurodynamical, neurochemical, evo- tionary, and clinical aspects, and that in doing so multiple methodological challenges arise that are worth considering and pursuing. The reader will find here, therefore, a selection of contributions that range from basic mechanisms of attention at the n- ronal level to developmental aspects of cognitive control and its impairments. Another trend that will become evident is that, in different ways, the authors stress the need to understand these issues as they unfold in natural behavior (both healthy and pathological), thus arguing for a more ecological approach to these questions.

Available in PDF, EPUB and Kindle. Book excerpt: Embodied cognition represents one of most important research programs in contemporary cognitive science. Although there is a diversity of opinion concerning the nature of embodiment, the core idea is that cognitive processes are influenced by body morphology, emotions, and sensorimotor systems. This idea is supported by an ever increasing collection of empirical studies that fall into two broad classes: one consisting of experiments that implicate action, emotion, and perception systems in seemingly abstract cognitive tasks and the other consisting of experiments that demonstrate the contribution of bodily interaction with the external environment to the performance of such tasks. Now that the research program of embodied cognition is well established, the time seems right for assessing its further promise and potential limitations. This research topic aims to create an interdisciplinary forum for discussing where we go from here. Given that we have good reason to think that the body influences cognition in surprisingly robust ways, the central question is no longer whether or not any cognitive processes are embodied. Instead, other questions have come to the fore: To what extent are cognitive processes in general embodied? Are there disembodied processes? Among those that are embodied, how are they embodied? Is there more than one kind of embodiment? Is embodiment a matter of degree? There are a number of specific issues that could be addressed by submissions to this research topic. Some supporters of embodied cognition eschew representations. Should anti-representationalism be a core part of an embodied approach? What role should dynamical models play? Research in embodied cognition has tended to focus on the importance of sensorimotor areas for cognition. What are the functions of multimodal or amodal brain areas? Abstract concepts have proved to be a challenge for embodied cognition. How should they be handled? Should researchers allow for some form of weak embodiment? Currently, there is a split between those who offer a simulation-based approach to embodiment and those who offer an enactive approach. Who is right? Should there be a rapprochement between these two groups? Some experimental and robotics researchers have recently shown a great deal of interest in the idea that external resources such as language can serve as form of cognitive scaffolding. What are the implications of this idea for embodied cognition? This research aims to bring together empirical and theoretical work from a diversity of perspectives. Subtitling is one of the most important disciplines in the history of social sciences, with the help of cognitive psychology. Researchers are encouraged to submit papers to discussing the future of embodied cognition, methods, models, or theories.

Available in PDF, EPUB and Kindle. Book excerpt: Motor Learning and Performance: From Principles to Application, Sixth Edition With Web Study Guide, enables students to appreciate high-level skilled activity and understand how such incredible performances occur. Written in a style that is accessible even to students with little or no knowledge of physiology, psychology, statistical methods, or other basic sciences, this text constructs a conceptual model of factors that influence motor performance, outlines how motor skills are acquired and retained with practice, and shows students how to apply the concepts to a variety of real-world settings. The sixth edition of Motor Learning and Performance has been carefully revised to incorporate the most important research findings in the field, and it is supplemented with practice situations to facilitate a stronger link between research-based principles and practical applications. Other highlights include the following: A web study guide offers updated principles-to-application exercises and additional interactive activities for each chapter, ensuring that students will be able to transfer core content from the book to various applied settings. Extensive updates and new material related to the performance of complex movements expand the theoretical focus to a more in-depth analysis of dynamical systems and the constraints-led approach to learning. Narratives from Motor Control in Everyday Actions that appear in the web study guide tie each book chapter to concrete examples of how motor behavior is applicable to real life. Photo caption activities pose questions to students to encourage critical thinking, and answers to those questions are provided to instructors in the instructor guide. As the text investigates the principles of human performance, pedagogical aids such as learning objectives, key terms, and Check Your Understanding questions help students stay on track with learning in each chapter. Focus on Research and Focus on Application sidebars deliver more detailed research information and make connections to real-world applications in areas such as teaching, coaching, and therapy. The sixth edition of Motor Learning and Performance: From Principles to Application goes beyond simply presenting research—it challenges students to grasp the fundamental concepts of motor performance and learning and then go a step further by applying the concepts. Incorporating familiar scenarios brings the material to life for students, leading to better retention and greater interest in practical application of motor performance and learning in their everyday lives and future careers.

Available in PDF, EPUB and Kindle. Book excerpt: In Perception: First Form of Mind, Tyler Burge develops an understanding of the most primitive type of mental representational: perception. Focusing on the functions and capacities of perceptual states, Burge accounts for their representational content and structure, and develops a formal semantics for them. The discussion explains the role of iconic format in the structure. It also situates the accounts of content, structure, and semantics within scientific explanations of perceptual-state formation, emphasizing formation of perceptual categorization. In the book's second half, Burge discusses what a perceptual system is. Exploration of relations between perception and other primitive capacities-conation, attention, memory, anticipation, affect, learning, and imagining-helps distinguish perceiving, with its associated capacities, from thinking, with its associated capacities. Drawing mainly on vision science, not introspection, Perception: First Form of Mind is a rigorous, agenda-setting work in philosophy of perception and philosophy of science.

Available in PDF, EPUB and Kindle. Book excerpt: This volume represents the proceedings of a NATO Advanced Study Institute (ASI) on the topic of "Motor Neuroscience" held at the Hotel San 15-24, 1990. The San Bastiano Hotel Bastiano, Calcatoggio (Corsica), September provided a beautiful setting for the ten day ASI in aresort on the west coast of Corsica, near the island's capital city of Ajaccio. The motivation of this ASI originated from the success of an ASI that we organized eleven years ago at Senanque Abbey in the south of France. Our earlier meeting was successful in providing some coherence to a widely scattered literature while providing up to date knowledge on motor control and learning. Our goal for the second ASI was essentially the same. We wanted to appraise the main theoretical ideas that currently characterize the field by bringing together many of the internationally known scientists who are doing much of the contemporary work. It is our hope that these proceedings will provide some conceptual unification to an expanding and diverse literature on motor control.

This book was released on 2016-05-18 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now strong evidence demonstrating that the brain simulates action and other functions. Such action simulation can be evoked through conscious mental rehearsal of movement or imagery, but also through passive action observation watching movements in others. Furthermore, there is evidence to suggest that mental rehearsal of movement, or mental practice, can produce improvements normally attributed to practising actual movements. It is currently assumed that such improvements are due to neural activation associated with action simulation. However the neuroscience of mental practice efficacy is still poorly understood. The aim of this research topic is to clarify the underlying mechanisms of mental practice, bringing evidence from cognitive neuroscience, experimental neuropsychology, sport and movement science, and clinical neurology. It also attempts to address confusion regarding the concepts of imagery and observation, which has hampered the progression of mental practice research both scientifically and applied. As well as reviews, theoretical, and position articles, this research topic includes original neuroimaging, experimental, and patient research addressing, among others, the following issues. Neuroimaging studies provide strong evidence for action simulation, but the link to behavioural change and functional outcome is weak. What is the evidence that mental practice efficacy is driven by neuroplasticity processes evoked by action simulation? This research topic includes contributions on neural correlates and behaviour with regards to imagery and action observation. Much of the mental practice efficacy evidence comes from longstanding research within sport science. However, what does mental practice entail in these contexts, and to what extent is it compatible with the cognitive neuroscience perspective of action simulation? This research topic will include contributions that consider both evidence and concepts with regards to imagery and action observation, in an attempt to build an interdisciplinary consensus on the nature and application of mental practice. Mental practice is perceived as a promising motor rehabilitation technique, but critically there is lack of clarity or consensus on what mental practice treatment should entail. It is also not clear what are the most appropriate outcomes to measure imagery ability and cognitive or behavioural change following mental practice. A further important issue that needs consideration as part of this research topic is dosage, as it is currently unclear how much mental practice is appropriate and whether this depends on patient variables such as age, cognitive functioning, motor function, or pathophysiology.
