Vision and Goal-Directed Movement: Neurobehavioral Perspectives is also available as an e-book. The e-book is available at a reduced price and allows readers to highlight and take notes throughout the text. When purchased through the Human Kinetics Web site, access to the e-book is immediately granted when the order is received. 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.

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.

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.

The discovery of mirror neurons caused a revolution in neuroscience and psychology. Nevertheless, because of their profound impact within life sciences, mirror neuron are still the subject of numerous debates concerning their origins and their functions. With more than 20 years of research in this area, it is timely to synthesise the expanding literature on this topic. 'New frontiers in Mirror Neurons' provides a comprehensive overview of the latest advances in mirror neurons research - accessible both to experts and to non-experts. In the book, leading scholars draw on the latest research to examine methodological approaches, theoretical implications, and the latest findings on mirror neurons research. A broad range of topics are covered within the book: basic findings and new concepts in action-perception theory, functional properties and evolution, development, and clinical implications. In particular, the last two sections of the book outline the importance of the plasticity and development of the mirror neuron system. This knowledge will be key in future research for helping us understand possible disorders associated with impairments in the mirror neurons system, as well as in helping us design new therapeutic tools for interventions within the field of neurodevelopmental disorders and in neurorehabilitation. 'New Frontiers in Mirror Neurons' is an exciting new work for neuroscientists, psychologists, and philosophers of mind.

The present volume covers the physiology of the visual system beyond the optic nerve. It is a continuation of the two preceding parts on the photochemistry and the physiology of the eye, and forms a bridge from them to the fourth part on visual psychophysics. These fields have all developed as independent speciali ties and need integrating with each other. The processing of visual information in the brain cannot be understood without some knowledge of the preceding mechanisms in the photoreceptor organs. There are two fundamental reasons, ontogenetic and functional, why this is so: 1) the retina of the vertebrate eye has developed from a specialized part of the brain; 2) in processing their data the eyes follow physiological principles similar to the visual brain centres. Peripheral and central functions should also be discussed in context with their final synthesis in subjective experience, i. e. visual perception. Microphysiology and ultramicroscopy have brought new insights into the neuronal basis of vision. These investigations began in the periphery: HARTLINE'S pioneering experiments on single visual elements of Limulus in 1932 started a successful period of neuronal recordings which ascended from the retina to the highest centres in the visual brain. In the last two decades modern electron microscopic techniques and photochemical investigations of single photoreceptors further contributed to vision research.

Coordinated gaze and hand movements predominate a number of our interactions in reachable space and yet few studies examine the potential contribution of tactile feedback in planning these actions. This thesis was designed to investigate eye and hand coordination during movement sequences when reaching out to interact with objects. We developed a virtual reality paradigm that allowed us to control visual, tactile, and in some cases, auditory feedback provided to participants. Participants reached and touched five objects in succession. We measured behaviour that resulted from removing one or more of the aforementioned sources of feedback - focusing on task accuracy, and the timing and dynamics of eye and hand movements. Our principle manipulations were to remove visual feedback of the hand, and/or to change the object response to contact. We also unexpectedly removed tactile feedback signaling contact. In Experiment 1, we examined gaze and hand movement timing relative to contact events. Gaze remained long enough to capture contact in central vision, but also followed a time course indicating that contact timing was predicted. In Experiment 2 we examined the influence of dynamic object consequences (i.e., motion). Gaze remained to monitor consequences that follow initial contact especially when the hand was invisible; with longer delays it became difficult to differentiate between predictive or reactive movements. In Experiment 3 we directly tested whether gaze would hold upon a site of action during prolonged manipulation. Here, gaze remained past contact time and instead its departure was associated with the completion of action. Our findings are congruent with the notion that visually guided reaches are controlled to facilitate directing the hand to viewed locations of action - without visual feedback of the hand accuracy diminished and hand approach changed across all experiments. However, we provide consistent evidence that gaze is also controlled to capture planned sensory consequences related to action at its viewed location. Monitoring these sites would facilitate comparing predicted sensory events with those that are actively measured and improve control throughout the movement sequence. Such a process also indicates the importance of considering tactile feedback when examining coordinated eye and hand movements.
