This second edition of Life Span Motor Development leads students with little or no background in the movement sciences through the principles, research and applied practice of motor development from infancy through older adulthood. The text is divided into three parts. Part 1 provides an overview of motor development. Part 2 follows motor development from infancy through older adulthood; and part 3 discusses how motor development is affected by perceptual and cognitive development, physiological responses to training, and psychosocial factors.
