Humans engage in a seemingly endless variety of different behaviors, of which some are found across species, while others are conceived of as typically human. Most generally, behavior comes about through the interplay of various constraints – informational, mechanical, neural, metabolic, and so on – operating at multiple scales in space and time. Over the years, consensus has grown in the research community that, rather than investigating behavior only from bottom up, it may be also well understood in terms of concepts and laws on the phenomenological level. Such top down approach is rooted in theories of synergetics and self-organization using tools from nonlinear dynamics. The present compendium brings together scientists from all over the world that have contributed to the development of their respective fields departing from this background. It provides an introduction to deterministic as well as stochastic dynamical systems and contains applications to motor control and coordination, visual perception and illusion, as well as auditory perception in the context of speech and music.

How Does the Body’s Motor Control System Deal with Repetition? While the presence of nonlinear dynamics can be explained and understood, it is difficult to be measured. A study of human movement variability with a focus on nonlinear dynamics, Nonlinear Analysis for Human Movement Variability, examines the characteristics of human movement within this framework, explores human movement in repetition, and explains how and why we analyze human movement data. It takes an in-depth look into the nonlinear dynamics of systems within and around us, investigates the temporal structure of variability, and discusses the properties of chaos and fractals as they relate to human movement. Providing a foundation for the use of nonlinear analysis and the study of movement variability in practice, the book describes the nonlinear dynamical features found in complex biological and physical systems, and introduces key concepts that help determine and identify patterns within the fluctuations of data that are repeated over time. It presents commonly used methods and novel approaches to movement analysis that reveal intriguing properties of the motor control system and introduce new ways of thinking about variability, adaptability, health, and motor learning. In addition, this text: Demonstrates how nonlinear measures can be used in a variety of different tasks and populations Presents a wide variety of nonlinear tools such as the Lyapunov exponent, surrogation, entropy, and fractal analysis Includes examples from research on how nonlinear analysis can be used to understand real-world applications Provides numerous case studies in postural control, gait, motor control, and motor development Nonlinear Analysis for Human Movement Variability advances the field of human movement variability research by dissecting human movement and studying the role of movement variability. The book proposes new ways to use nonlinear analysis and investigate the temporal structure of variability, and enables engineers, movement scientists, clinicians, and those in related disciplines to effectively apply nonlinear analysis in practice.

The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable pertur bations, has a long history. However, despite a history of magnificent sculptures and drawings of the human body which vividly depict muscle ac tivity and interaction, until more recent times our state of knowledge of human movement was rather primitive. During the past century this has changed; we now have developed a considerable database regarding the com position and basic properties of muscle and nerve tissue and the basic causal relations between neural function and biomechanical movement. Over the last few decades we have also seen an increased appreciation of the impor tance of musculoskeletal biomechanics: the neuromotor system must control movement within a world governed by mechanical laws. We have now col lected quantitative data for a wealth of human movements. Our capacity to understand the data we collect has been enhanced by our continually evolving modeling capabilities and by the availability of computational power. What have we learned? This book is designed to help synthesize our current knowledge regarding the role of muscles in human movement. The study of human movement is not a mature discipline.

Nonlinear Pedagogy is a powerful paradigm for understanding human movement and for designing effective teaching, coaching and training programmes in sport, exercise and physical education (PE). It addresses the inherent complexity in learning movement skills, viewing the learner, the learning environment and the teacher or coach as a complex interacting system. The constraints of individual practice tasks provide the platform for functional movement behaviours to emerge during practice and performance. The second edition includes new materials, of practical, theoretical and empirical relevance, to enhance understanding of how to implement a Nonlinear Pedagogy to support learning in sport, PE and physical activity. There is updated, in-depth discussion on the various pedagogical principles that support Nonlinear Pedagogy and how these principles are applicable in learning designs in sports and physical education. There is further emphasis on examining how transfer of learning is implicated in practice, highlighting its relevance on skill adaptation and talent development. The first part of the book updates the general theoretical framework to explain processes of skill acquisition and motor learning. This edition draws clearer links between skill acquisition, expertise and talent development, focusing on how specificity and generality of transfer have a role to play in the development of learners. The book defines Nonlinear Pedagogy and outlines its key principles of practice. It offers a thorough and critical appraisal of the functional use of instructional constraints and practice design. It discusses methods for creating challenging and supportive individualised learning environments at developmental, sub-elite and elite levels of performance. The second part focuses on the application of Nonlinear Pedagogy in sports and PE. There is a greater emphasis on helping applied scientists and practitioners understand the impact of Nonlinear Pedagogy on transfer of learning. Every chapter is updated to provide relevant contemporary cases and examples from sport and exercise contexts, providing guidance on practice activities and lessons. Nonlinear Pedagogy in Skill Acquisition is an essential companion for any degree-level course in skill acquisition, motor learning, sport science, sport pedagogy, sports coaching practice, or pedagogy or curriculum design in physical education.

Understanding the conditions under which variability in performance may arise, and the processes related to its emergence, gives us insight into the development of techniques for improving the quality of performance. Variability in Human Performance details the scientific and the practical implications of human performance variability by providing a broad perspective on how and why such variability occurs across a number of disciplinary domains. The text takes an approach that rests upon the idea of context, or design, specificity in performance, namely that variability in performance is closely referenced to design factors in the environment in which performance is occurring. An exploration of the link between variability and related processes, the book introduces a comprehensive framework for understanding human performance variability, presented in terms of how human control of behavior is closely tied to design factors in the performance environment. The authors introduce empirical evidence, as well as practical examples and application areas, in support of this framework. The book begins with coverage of neurobiological and biomechanical basis of movement variability, then examines rich and extensive empirical evidence available for context specificity in cognitive performance and learning, as a basis for cognitive performance variability. The book then reviews the evidence for context specificity in: Student learning Displaced feedback conditions Human error behavior Affective performance Social and team performance The authors also explore work performance as influenced by complex sociotechnical systems and as a basis for performance variability, applying control systems concepts to an interpretation of the nature and basis of performance variability in all of these domains. They conclude by taking an evolutionary perspective on the origins and behavioral significance of human performance variability. The book then provides strategies on how individuals, groups, and organizations can significantly reduce variability in human performance that often leads to systems failures.

This book is an attempt to advance the discussion and improve our understanding about the effects of aging and movement disorders on motor control during walking and postural tasks. Despite these activities are performed daily, there is a high requirement of motor and neural systems in order to perform both tasks efficiently. Both walking and posture require a complex interaction of musculoskeletal and neural systems. However, the mechanisms used to control these tasks, as well as how they are planned and coordinated, are still a question of discussion among health professionals and researchers. In addition, this discussion is more interesting when the effects of aging are included in the context of locomotion and the postural control. The number of older individuals is 841 million in 2015, which is four times higher than the 202 million that lived in 1950. Aging causes many motor, sensorial and neural deficits, which impair locomotion and postural control in the elderly. The severity of this framework is worsened when the aging goes along with a movement disorder, such as Parkinson disease, Chorea, Dystonia, Huntington disease, etc. Therefore, the aim of this book is to highlight the influence of different aspects on planning, controlling and performing locomotion and posture tasks. In attempting to improve current knowledge in this field, invited authors present and discuss how environmental, sensorial, motor, cognitive and individual aspects influence the planning and performance of locomotor and postural activities. The major thrust of the book is to address the mechanisms involved in controlling and planning motor action in neurological healthy individuals, as well as in those who suffer from movement disorders or face the effects of aging, indicating the aspects that impair locomotion and postural control. In addition, new technologies, tools and interventions designed to manage the effects of aging and movement disorders are presented in the book.
