Document Summary
Average 2. 5 in. in height and 5-7 lbs. during early childhood. Size of brain does not increase dramatically from ages 3-15: amount of brain material doubles in some areas in as little as a year, a dramatic loss of tissue as cells are pruned and the brain reorganizes itself. From 3-6 years of age the frontal lobes prefrontal cortex: key role in planning and organizing new actions and maintaining attention to tasks. Number and size of dendrites increase and myelination continues the process in which axons are covered with a layer of fat cells, which increases the speed and efficiency of information traveling though the nervous system: motor development. Age 4: play on low jungle gyms beginning to learn to come down steps one foot on each step. Age 3: build blocks, but not in a straight line not precise in placing puzzle pieces. Age 4: place blocks perfectly on top of each other.
