Research is reviewed concerning the current state of knowledge about normal hemispheric specialization; distinctions among such terms as dominance, laterality, and lateralization; and models of abnormal cerebral organization in dyslexic children. The question of dyslexic subtypes is undertaken along such dimensions as handedness, eyedness, and…

Five theories were tested relating to the suspected connection between organic brain dysfunction and poor reading, or dyslexia. Results failed to support the poor lateralization, right hemisphere, global, imbalance theories. Among juvenile offenders, poor reading appears to relate to left-hemisphere dysfunction. (Author)

Authors suggest that consideration be given to maximizing the opportunies for systems in either cerebral hemisphere to develop fully in early life, when the child is essentially split-brained," so that developmental imbalance does not exist when the two hemispheres later begin to communicate.

This paper presents background information, an introductory statement of theoretical positions, and brief abstracts of research papers from a symposium on the functional specialization of cerebral hemispheres in infants and children. According to one view of the development of cerebral specialization, the two hemispheres are initially…
