There are many theories and models that attempt to explain the development of movement in children. This book combines several models to create one framework for viewing motor development. Motor abilities fall into two main categories: gross motor skills and fine motor skills; most scientists concur that there are at least three broad categories within gross motor and fine motor development and sometimes are overlapping. This book discusses these categories - postural stability, locomotion, and manipulative skills – and how, particular to this discussion, a child's ability to learn is interwoven with his ability to utilize the senses, particularly those involving tactile, visual, auditory and somatosensory input.
