Document Summary

Gender differences in height/weight development: boys become stronger than girls early in adolescence because of their greater muscular development, girls are less inclined to remain physically active. Upward growth: proximodistal development sequence of physical maturation and growth that proceeds from the center of the body (proximal region) to the extremities (distal region) Motor development trends and explanations/theories of sequencing/timing: proceeds in cephalocaudal and proximodistal directions, evolve in a definitive sequence. Infants gain control over their heads, necks and upper arms before they become proficient with their legs, feet and hands: experimental hypothesis - experience is important. Children with few opportunities to practice motor skills have retarded development. Development can be accelerated with practice: dynamical systems theory motor skills are active reorganizations of previously mastered capabilities undertake to find more effective ways of exploring the environment. Motor skills are not viewed as genetically programmed responses that unfold as dictated by maturation and opportunities.
