The article cites a research study focusing on dichotic listening. A number of authors have written about the development of the dichotic right ear advantage in children. Researchers interpret these dichotic listening data for children between the ages of five and ten as showing no significant change with age in the degree of right ear advantage. This study has shown that not only is the size of the right ear advantage contingent upon the precision on onset-alignment, but that the voiceless constant volumes (CVs) are much more intelligible dichotically than voices CVs. To the phonetically and linguistically oriented researcher, the careful use of dichotic stimuli whose acoustic differences can be specified, assesses the phonetic versus acoustic contribution of the stimuli to the right ear advantage. Most writers are in agreement that language skills in certain areas, and certainly reading and writing skills, improve between the ages of 5 and 13. It must be concluded, therefore, that the right ear advantage, as measured by dichotic listening to nonsense CVs, is not an index of total overall language performance.
