We humans undergo two major growth spurts: one during infancy and another from eleven to twelve until fifteen or sixteen--pubescence. Between the two is a relatively quiescent growth period in which most of the body takes a rest from growing while the brain continues to mature. This period of life is general referred to as childhood or, sometimes, latency.
