This book's main focus is the development of skilled motor actions by children: commonplace but vital actions such as maintaining posture, walking, reaching and grasping, and manipulating objects and tools. It represents a state-of-the-art report on motor development linking neurophysiological and neuropsychological approaches. Contributors employ examples from both normal and pathological development to study pre- and postnatal brain development and its relationship to skilled motor actions and patterns of behavioral change.
