Human Motor Development in Individuals with and without Disabilities [PDF ebook] 

By five months of life, babies can raise their heads when in a supine position on the floor. This common and expected progression in controlling the head is just one example of early human motor development. Human motor performance is one of the fundamental aspects of the sensory-motor system. Many questions appeal to researchers in the field of movement science and other areas such as neuroscience, psychology, physiology, education, pediatrics, and geriatrics. For example, how do humans learn and control movements? This book follows the improvement of motor skills in childhood as a function of enriched experiences or maturation, as well as illustrating how developmental studies on motor performance increase our understanding of perceptual-motor skills.
