title: Differential effects of congenital left and right brain injury on intelligence.
abstract: IQ performance was compared in 28 prepubertal children with unilateral left vs. right hemisphere preperinatal injury. Results indicated statistically superior FSIQ and VIQ in the left-lesioned group. Findings were interpreted as consistent with the hypothesis of a left-right maturational gradient, whereby early right hemisphere damage has a more severe effect on overall intellectual functioning than early left injury. Findings also lend support for a greater crowding effect, as seen in the sparing of verbal skills, after early left hemisphere injury.
