title: Auditory perception in early lateralized brain damage.
abstract: In a study of hemispheric dominance for the perception of speech the performance of 28 young children with congenital or infantile hemiplegia was compared with that of their normal peers and recently brain damage nonaphasic adults. Our results confirm Goodglass's findings that in children with early left hemisphere damage the transfer of dominance for speech processing is completed in childhood, and they show that this process of hemispheric transfer can be completed by 3 years of age. Comparison with results on adults with CVA provides additional evidence that in early lateralized brain cognitive functions normally dominant in one cerebral hemisphere are developed in the alternative hemisphere in a way that apparently does not happen later in life.
