AND PERSONALITY 



the protoplasmic bridge with a blank matrix. This enables 

 the infant, the child, and the adult to acquire action 

 patterns from their environment. 



In correlating the anatomical facts of the energy systems 

 of the infant and the child with their behavior, we find that 

 the infant and the child, like the young of all wild animals, 

 are highly cephalized and adrenalized. The infant and the 

 child show emotionalism and quick response to fevers. It is 

 not enough to say that these phenomena occur because the 

 individual is an infant or a child. We must conclude that 

 the behavior of the infant and the child and the phenomena 

 that they exhibit are due to a far greater development of 

 the brain and adrenal glands than is present in the adult. 



Through phylogeny racial experience the energy-con- 

 trolling system is an inherited energy pattern. Evolution 

 endowed the young of wild animals with as large a brain, 

 thyroid gland, and adrenal glands as was possible for sur- 

 vival without heatstroke. 



When a child has reached ten to twelve years of age, the 

 adrenal glands and the thyroid gland approximate each 

 other in weight. This changed relation in the size of the 

 thyroid and adrenal glands is expressed in the behavior 

 of the child. During this time the child is an energy machine, 

 and, significantly, this period of childhood often points 

 to the fact that the child is "father of .the man." On the one 

 hand, a child may be too highly energized, too incessantly 

 active for his future safety. In that event, his physical 

 powers should not be unduly developed in school lest in 

 adult life he develop such diseases of civilized man as 

 essential hypertension, coronary disease, or the cardiorenal 

 syndrome. 



On the other hand, a child may possess so high an equip- 

 ment for mental work as to endanger his safety in another 

 direction. Child prodigies should be restrained rather than 

 stimulated. They should be trained to offset mental and 

 emotional work by interests other than mental lest in adult
