Outcomes of hemisphericity questionnaires correlate with unilateral dichotic deafness.
Using the Dichotic Deafness Test, 145 university workers were separated into dichotic deafness and hearing groups based on minor ear responses to dichotic consonant-vowel stimuli. They were also separated into putative right and left brain-oriented groups by Zenhausern's Preference Questionnaire. Interestingly, members of the dichotically hearing group chose mainly right brain-oriented answers and vice versa. A correlation coefficient twice that obtained for Zenhausern's Preference Questionnaire resulted when subject groups separated by the novel Polarity Questionnaire were compared to Dichotic Deafness Test groups. Only 30% of Preference Questionnaire items, versus 90% of Polarity Questionnaire items, were significantly correlated with Dichotic Deafness Test groups. This is the first report of hemisphericity-type questionnaires showing significant correlations with a biophysical measure of brain laterality.
