A callosal transfer deficit in children with developmental language disorder.
Twenty-two control children (aged 6-12 years) and forty-three children with developmental language disorder (DLD) (aged 7-12 years) received a test of callosal transfer of tactile information. Among the children with dysphasia, 30 had a diagnosis of receptive dysphasia and 13 of expressive dysphasia. Both control children and children with DLD made a significantly larger number of errors in the crossed localization condition (implying callosal transfer of tactile information) versus the uncrossed localization condition. In the crossed localization condition, children with DLD made a significantly larger number of errors than controls, while no differences were found in the two groups of children with DLD. These data suggest that the corpus callosum may be involved in the pathogenesis of DLD.
