There are many children who lack this cross-pattern function, and they reflect coordination problems to a certain extent. Coordinated gross motor action culminates in a cross pattern whether it's bowling, doing a basketball lay-up, or throwing a baseball pitch. A child who lacks complete organization will display a loss of coordination to some degree. Interestingly, there is the rare child who is neurologically dysorganized but has good coordination. Such children generally have other inefficiencies, particularly mixed dominance.
Neurological organization culminates at the top cortical level of the brain.
This organization is the establishment of cortical-hemispheric dominance. This is the establishment of a dominant hemisphere, or side. To assess your child's dominance, begin by evaluating the function of his hands. You can find out if he has a dominant hand, as this will be the hand he writes with, throws a ball with, etc. These functions should all be done with the same hand.
