​Crossed-uncrossed differences of visual and auditory modalities in musicians and non-musicians

The purpose of this study is to examine the effect of musical training on inter-hemispheric communication. This study will involve calculating inter-hemispheric transmission times from reaction times to visual and auditory stimuli of individuals with or without musical training.Visual and auditory sensory information is relayed between hemispheres by the corpus callosum of the brain. Previous research has shown that musical training may affect callosal development. Also, studies have shown that musicians and non-musicians show differences in callosal size. With this information, we predict that musicians will show shorter reaction times to visual and auditory stimuli than non-musicians. Another part of this study predicts that those with musical training after age 10 (late-trained musicians) will show results similar to non-musicians, since the timing of musical training does not coincide with the of time span of extensive callosal development.
