Document Summary
Putting together skill to achieve a goal within the constraints set by the body and environment: tuning: repeated cycles of action and perception of the consequences. What are some reflexes of infants: predisposition to respond adaptively to their environment before they have had the opportunity to learn, some reflexes persist throughout life and become incorporated into more complex voluntary actions, some do not. They can vary individually: rooting reflex, sucking, moro, grasping, not automatic. What are gross motor skills, and how do they develop: skills involving large-muscle activities, posture: dynamic process linked with sensory information in skin, joints, muscles telling us where we are in space. Newborns cannot voluntarily control their posture: walk: need to control leg alternation, stabilize balance and shifting weight. Practice is important: timing varies; experience can modify onset, cultural variations exist, childhood: activity is source of considerable pride in accomplishment. Participation in sport can be positive or negative: adolescence/adulthood: improve in adolescence.
