This volume provides a complete description of the relationship between learning to read and hemispheric functioning, which has been found to change the course of development. Initial reading skills are controlled primarily by the right cerebral hemisphere, but as readers become more advanced, the left hemisphere becomes dominant. Some children fail to make this shift and are at risk of developing one type of dyslexia, while children who prematurely rely on left-hemispheric reading strategies may develop another type. These two types of dyslexia have been found to respond to different types of stimulation. The book includes comprehensive information on these treatments, with extensive discussion of their strengths, weaknesses, and limitations, along with an analysis of a number of experimental, field, and individual case studies.
