Subjects wore insert earphones (ER3-14A, Etymotic Research, Elk Grove Village, Illinois) and performed diotic and dichotic digits listening. ScienceBlogs Channel : Life Science Tara C. Dichotic listening is a well-established method to non-invasively assess hemispheric specialization for processing of speech and other auditory stimuli.
