Gender differences when touching something gross: unpleasant? No. Disgusting? Yes!

While many studies find women self-report higher disgust sensitivity than men, few studies have examined gender differences with behavioral tasks in senses other than vision. On a haptic task, we tested the hypothesis that women would report greater disgust but not greater unpleasantness than men. Forty-four undergraduates (29 women) touched 8 out-of-sight stimuli with sensory (unpleasantness) and emotional (disgust) responses recorded. The stimuli consisted of 2 neutral, 2 pleasant, and 4 unpleasant (3 disgust-evoking) objects. No gender differences were found for reporting stimuli unpleasantness. In contrast, women rated their disgust significantly higher than men when touching the high disgust-evoking objects. Unpleasantness of the stimuli correlated with disgust to the objects, but disgust sensitivity (Disgust Scale-Revised) was not a strong predictor of disgust responses. Besides differentiating unpleasantness from disgust, this was also the first study to show gender differences in a disgust-evoking haptic task.
