Document Summary
Body growth: typical gain in height is 50% by age 1, 75% by age 2, baby fat peaks at about 9 months, muscle tissue increases slowly, peaking in adolescence. Physical growth trends: cephalocaudal trend, head to tail , head develops more rapidly than lower part of the body, proximodistal trend, near to far , head, chest, and trunk grow ahead of extremities. Lateralization of the cerebral cortex: lateralization: specialization of the two hemispheres, left hemisphere, better at sequential, analytic processing, good approach for communicative information, right hemisphere, specialized for holistic, integrative processing, good for spatial abilities and regulating negative emotion. Brain plasticity: brain plasticity, if part of the cerebral cortex is damaged, other parts can take over tasks it would have handled, brain is highly plastic during the first few years. The sequence of motor development: gross-motor development, crawling, standing, walking, fine-motor development, reaching, grasping. Gross- and fine-motor development in the first two years.
