Document Summary
Newell"s model of constraints: constraints, limit or discourage certain movements, permit or encourage other movements, shape movement, structural constraints, individual constraints, physical attributes; height, weight, changes in muscle mass, quantitatively measure, functional constraints, attention focus. Constraints and atypical development: disabilities: differences in structural, functional individual constraints, must consider all interacting constraints, may result in delayed, different motor development. A paradox in development: universality: individuals in a species show great similarity in development, variability: individual differences exist. Ii: genetic code and physiological development; genetically driven, biological influence, very minimal environmental influence. How do new skills appear: more development in the central nervous system so that when you see something you can put it into action-systems have to develop in order to create the actions. For maturation systems have to develop to a certain point and work together to get these behaviors: certain systems mature enough to a pint where they act together and a skill is performed.
