Document Summary

Lecture 7 - school aged (6 to 8 years) Although the changes are more difficult to observe directly, the physical changes in middle childhood are just as impressive as those in early childhood. Growth patterns 5-8cm in height and 2. 75kg each year. Large muscle coordination continues to improve, children show increases in strength and speed, and hand-eye coordination also gets better. Increasingly good fine motor coordination makes writing possible as well as drawing, cutting and many other skills. Steady increase in the myelinization of neural axons across the cerebral cortex with sensory and motor areas affected first which may be linked to the improvement in fine motor skills and hand eye coordination. Boys score better than girls on spatial orientation. Boys early play may enhance this ability. Visual experience is important in the development of spatial perception. Of overweight children become overweight adults.
