Document Summary
Physical changes between 2 and 6 are less dramatic than those in infancy and occur more slowly. Each year from about 2 to adolescence, kids gain about 5-8cm in height and about 27kg in weight. Children who exhibit higher motor activity levels demonstrate a significantly better ability to control or inhibit their behaviour allowing for successful task achievement. Children"s motor activity levels increase linearly with age and tend to peak between 7-9 years or age later than previously thought. Preschool child makes steady progress in motor development. Most impressive gains in large muscle skills. This can be seen in the development of drawing skills. Brain growth, synapse formation and myelinization continue in early childhood, although at a slower pace than in infancy. Myelinization of the reticular formation brain structure that regulates attention and concentration. Hippocampus maturation accounts for improvements in memory function across the preschool years. What if the hippocampus was not myelinated: wouldn"t be able to store memories, amnesia.
