Scholastic aptitude and achievement among children with unilateral brain lesions.

Cognitive abilities, scholastic aptitude and academic achievement were studied for 20 left hemisphere lesioned (LL) and 12 right hemisphere lesioned (RL) children in comparison with matched peers. On the Cognitive clusters, both LL and RL children performed significantly poorer than controls on the reasoning, perceptual speed and memory clusters. For the Scholastic Aptitude clusters, lesioned subjects performed significantly lower than controls on all clusters except for the knowledge cluster. On the Academic Achievement clusters, LL performed significantly poorer on the written language cluster while RL performed lower on the reading, math and written language clusters. Age of lesion onset, site of lesion and IQ differences are discussed in relationship to the ability clusters measured.
