title: Outcomes of hemisphericity questionnaires correlate with unilateral dichotic deafness.
abstract: 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.
