The hemispheric specialization for linguistic and non-linguistic tactile stimuli in third grade children.
Thirty third-grade children were given two dichaptically presented tests of hemispheric specialization. Specialization for linguistic stimuli was measured by a letters task and specialization for spatial stimulus was measured by a nonsense shapes task. The results showed a significant right hemisphere processing advantage for tactually presented spatial stimuli. There was no significant processing advantage for either hemisphere with tactually presented linguistic stimuli. The right hemisphere specialization for tactually presented spatial stimuli was present for both boys and girls. Thus there was no evidence of sexual bimorphism in the neurological organization of third grade children for spatial processing.
