Abstract
An attempt was made to replicate Hess and Polt's (1960) report of sex differences in pupillary responses to sex-stereotyped pictures. Some methodological refinements were used that seem desirable for future studies. College men and women were either shown or told they would be shown pictures of a semi-nude man, a semi-nude woman, a baby, and a landscape. With resting pupil size as covariate, a three-factor analysis of covariance did not show sex differences in response to visually presented stimuli. Men responded more to verbal than visual mode of presentation and more than women to verbal stimuli. Contrary to previous results, men responded as much or more than women to verbal or visual presentation of baby stimuli. The verbal or anticipatory mode seems to be at least as sensitive as the visual and eliminates problems of control of visual materials.
