The interaction of hemispheric preference, laterality, and sex in the perception of emotional tone and verbal content.

Twenty male and 20 female subjects, divided into those who showed a right or left hemispheric preference, listened to auditory messages with conflicting verbal content and emotional tone. The messages were presented to each ear to determine whether the effect of hemisphere of input on the evaluation of the messages was modified by hemispheric preference. Except for left preference males, subjects responded on the basis of preference rather than laterality.
