Abstract

This study compared the hemispheric dominance for language of three groups of 6- to 9-year-olds (10 language-disordered, 10 articulation-disordered, and 10 normal children). Two dichotic listening tests (digits and animal names) were administered. Statistical analysis revealed a left hemisphere dominance for the control and articulation-disordered groups but no significant hemisphere differences for the language-disordered group. The results support the hypothesis that the language-disordered child has an unlateralized cerebral dominance for language, while the articulation-disordered child has normal left cerebral hemisphere dominance for language. Furthermore, there is some evidence to suggest that the language-disordered child does not process auditory stimuli in the left hemisphere as efficiently as the articulation-disordered or normal child. These results also suggest the importance of developing strategies in the management of these disorders.
