I would also like to dedicate my work on this book to two master teachers I first encountered as an undergraduate: Dr. A. Gwendolyn Drew and Mrs. Jo Garrison. Undoubtedly, without them, I would be doing something else today! Kathleen Haywood I was able to study with “giants.” I thank them for their kindness to a young student with whom they enthusiastically shared their knowl- edge and passion for the study of motor development: Larry Rarick, Anna Espenschade, Helen Eckert, Vern Seefeldt and, especially, Lolas Halverson. I can only hope that I have deserved their generosity. Mary Ann Roberton To my parents, Walter L. and Susan D. Getchell, for giving me endless, unconditional encouragement over many years. In particular, thanks to my mother, who provided the block off of which I became a chip. Nancy Getchell Contents | Preface ix Acknowledgments xii Part I What Is Motor Development?

People who have studied motor development would say instead that nothing about the development of life is simple. The range of influences on developing beings is enormous, and the fact that these influences interact with one another paints a picture of rich complexity. Just consider one example: physical growth. Physical growth and physiological maturation proceed according to a genetic blueprint. Yet, a host of environmen- tal factors ranging from nutrition to carcinogens to climate to disease influence growth and maturation. The psychosocial environment across childhood and throughout adulthood can also affect physical status, either directly or through other environmental factors. These factors can support or impede growth and maturation. Their effect on physical status changes the interaction between the person and the environment, and so a complex interplay between the changing physical person and the environment’s many factors continues. The process of motor development is equally complex. Yet, this complexity is exactly what captures our interest. Each person is unique. Each person’s context is unique. A small difference early in development can result in a large differ- ence later in life. What intrigues us is finding the keys that unlock the mystery of understanding a person’s developmental status. The deeper we delve into the complex interaction of person, context, and purpose in movement, the more we appreciate the need to consider additional influencing factors. In this textbook, we examine many of the factors associated with and related to motor develop- ment. Furthermore, we explore where research within the field has been, where it is now, and where it might be in the future. PURPoSe This book is written for graduate or advanced students interested in both a broader and a deeper examination of the field of motor development. In this book, we focus on the ways in which both theoretical perspectives and research paradigms have influenced the understanding of developmental phenomena. This advanced text in motor development is designed to stimulate students to reach a deeper understanding and synthesis of the process and course of motor development and the great range of factors affecting that development. It is aimed at those who may have already studied the basic aspects of motor development and want greater in-depth knowledge and understanding. While graduate study in motor development traditionally has been approached through a variety of readings sometimes supplemented by an undergraduate text, this advanced text meets the need for in-depth study in a more cohesive way. It presents parallels and highlights relationships in a way that individual readings might not. It also provides a foundation in the theoretical underpinnings within the field as well as demonstrates how these theories drive contemporary research. ix x Preface A unique approach in this text that is consistent with its focus on an advanced audience is that when analyzing research about the various categories of move- ment skills, this book not only surveys the research findings on a topic but also highlights a smaller number of landmark studies or lines of research to discuss in depth. Advanced students must appreciate the process of research as well as learn to analyze research methods and results for themselves so that they can become both critical consumers of research and researchers themselves. Students can further expand the horizon of study on a particular topic, but they will benefit from expo- sure to the process and the detail of research studies addressing specific questions. Such analytical skills will prepare any student for selecting and exploring their own research topic. This text will help them transition into the role of engaging in motor development research, either as part of a research team or in the context of a thesis or dissertation. Moreover, for a student in an area other than motor development, this emphasis on critical analysis will help them to think about their own area in more sophisticated ways. Another popular saying is that the devil is in the details. For those who want to know more about motor development than can be covered in an undergraduate course, the fun is in the details. Learning the details of research and hence the complexities of motor development will increase your engagement, challenge, and excitement. It will also position you to frame your own research questions as you learn more about the process of developmental research. oRGAnIzAtIon The text has been organized into three parts. Part I, which is entitled What Is Motor Development? Theoretical Perspectives, explores the meaning of the phrase lifespan motor development from both a historical and a contemporary context. After introducing the field of motor development, chapter 1 examines the roots of motor development in describing motor behavior through the research of early developmentalists such as Gesell and McGraw. Chapter 1 also examines inter- and intratask motor skill sequences within the developmental sequence theory. Chapter 2 describes the movement of developmentalists toward considering developing beings in their context or environment. It reviews the transition from indirect to direct perception in specifying the relationship between perception and action. Chapter 3 parallels this paradigm shift in discussing dynamic systems perspectives, especially research studying the emergence and self-organization of movement from interacting subsystems. Finally, chapter 4 reviews the research methods and tools commonly used in motor development research. It also shows how to use inductive reason and strong inference (Platt, 1964) in the research process. Part II, which is entitled, What Perspectives Do Researchers Use to Study Motor Development? Contemporary Research, examines research agendas within specific classes of motor skills (posture, foot locomotion, ballistic skills, and manipulative skills). Each chapter in part II provides an overview of the research on two or three specific skills to demonstrate how research agendas can help answer specific questions about skill development. Chapter 5 explores pos- tural control. Chapter 6, on locomotion, covers walking and hopping. Chapter 7, ballistic skills, focuses on research on the overarm throw, striking, and kick-
