Research data in neurosurgery, neuropsychology, and neurolinguistics indicate that the human brain is lateralized toward one of two methods of information processing, and that, in most humans, the language bias appears to be a left hemisphere function, while the visiospatial bias belongs to the right. Furthermore, the left hemisphere seems to perceive and process information in parts, while the right hemisphere perceives and processes information in wholes. These data have been used to investigate many facets of the teaching/learning process. Such studies have discovered that readers who process written material using a predominantly left hemisphere strategy of sequencing, without integrating the right hemisphere visualization strategies, may be able to read but not comprehend. Those readers who appear to have good visualization skills--a right hemisphere strategy--but lack the sequencing skills of the left, have great difficulty developing overall reading skills. The educational challenge, therefore, becomes one of teaching the whole child, to approach each hemisphere's processing strengths, to provide exercises that will allow for the integration of perceptual strategies in reading, and to produce holistic thinkers.
