Amongst other notable work, Dr Clark chaired the NASPE - Early childhood Physical Activity Guidelines Task Force. It is with reference to a recent release on the guidelines for infants that Dr Clark summises, " adopting a physically active lifestyle early in life increases the likelihood that infants and young children will learn to move more skillfully: (Clark, 2002:1). Dr Clark goes on to provide a series of guidelines that appear to be the general consensus of the research in review throughout this paper. Substantial weight is given to the need (particularly on the part of the parent) to provide an environment dedicated to promoting the development of physical movement. In addition, Dr Clark states that " Individuals responsible for the well being of an infant should be aware of the importance of physical activity and facilitate the child's movement skills." (Clark, 2002:1) Of further interest is Dr Clarks maintenance of the position of the Dynamic Systems Approach to motor development. Dr Clark maintains that basic movement skills do not just appear because a child grows, but rather that there is an interaction between the functional individual and their movement experience. Clark goes on to suggest that reinforcement of those with whom the individual has a close bond with, can further enhance the aqusition of motor skills. It is this hypothesis that is the focus of an article by Patterson and Anderson .
Of particular concern is a study conducted by Rarick and McKee (1948) which suggests that the attainment of motor skills is closely linked to an interaction between the individuals intrinsic capacity and the environment surrounding them. In discussing this hypothesis, a series of tests were conducted examining ten highly developed children comparable with ten lower developed children in relation to the nature of their environments. From the results Rarick and McKee initially suggest that while .
