Document Summary
During preschool years, there is an addition of about 20 lbs and 10 inches (between ages 2 and 6) Weight difference increases (boys gain more weight) and height differences decrease (girls grow faster than boys) By age 5, child"s body is 30% the size of an adult"s and brain is 90% the size of an adult"s. Brain growth, how and why : increase in interconnectedness of neurons, increase in myelination (increases speed of information) *white brain matter is myelin; more white brain matter = more intelligence: thickening of corpus colosseum. Lateralization process in which certain functions are located more in one hemisphere than another. Many abilities have regions in both hemispheres. Sleep nightmares (vivid dream; rem sleep), night terrors (occurring in deep sleep; not a dream; awaking in a state of panic) Gross motor skills occur in a period of rapid growth due to myelination. Undo clothes, pour liquid, jigsaw puzzle, draw 0 & 1.
