ABSTRACT
This chapter explains the schizophrenic disorders are used to elucidate insights be gained on normal brain development from psychopathology, as well as to illustrate how knowledge of normal neural development provides important insights into the genesis and epigenesis of the serious mental disorder. Although influential developmentalists such as Wilhelm Preyer and Leonard Carmichael published major works detailing the unsolved problems in comprehending the relations between biological and behavioral development, and early editions of the Handbook of Child Psychology each provided scholarly reviews of the relation between biological and behavioral development, the epigenesis of neurobiological development was accorded little attention in the prominent developmental theories in existence through much of the 20th century. James Mark Baldwin asserted that much more knowledge about the process of brain development needed to be discovered before the study of child development and neurobiological growth could be integrated in a manner commensurate with the complexity of the developing child and nervous system.
