Research shows that persons with dyslexia may have bilateral neural involvement in spatial processing that interferes with the left hemisphere's processing of its own specialized functions. This results in deficient linguistic, sequential cognitive processing. (MLH)

Reports increased central nervous system vigilance and activation was observed as indicated by pupillary dilation during the decision interval of a letter matching task as higher levels of processing were performed. (SL)

Research shows that children of about 10 years can remember photographs of faces upside down almost as well as those shown upright and are easily fooled by simple disguises. This ability to encode orientation-specific configurations of a face may reflect maturational changes in the right cerebral hemisphere. (MLH)

Investigated the relationship between hand writing posture and cerebral dominance of 48 left handed writers and 25 right handed writers. Determined that cerebral dominance is related to handedness and to whether or not the writing hand posture is normal or inverted. (SL)
