Growth Spurt: Mass investigations on the basis of age norms, however, have indicated only a slight relation between the mental and physical status of children. A spurt in mental growth does not appear to parallel the preadolescent spurt in physical growth. The pattern of mental development is similar in boys and girls, despite the difference in their rates of physical maturing.
Adult stature can be predicted more accurately from a series of measures taken at nine, ten, and eleven years than from a series taken at eleven, twelve, and thirteen when the child is in the puberty cycle. It is also important to know whether the child is at the beginning, the peak, or the tapering off of the growth spurt. Gray (51, 1948) worked out a technical procedure for height prediction, based on the best features of methods already developed. Bayley (15, 1956) has shown that children of these ages have definite patterns of development which allow fairly accurate predictions of adult-growth status.
Lateral growth in trees frequently begins later than growth in height, but the period of lateral growth is longer. Rates of lateral growth likewise are low at the outset, increasing after a few weeks and then diminishing. In view of the long annual period of lateral growth in trees, deleterious environmental conditions may exercise a pronounced effect on growth. In the wood of trees of temperate regions, narrow and wide growth rings may be observed, marking years characterized by unfavorable and favorable conditions for growth.
