Abstract
Twelve female graduate student volunteers were presented with two sets of sex‐related stories. One set was classified as erotically realistic and the other as hard‐core pornography. Sexual arousal was measured physiologically by means of a vaginal photoplethysmograph and subjectively by self‐report scales. Both sets of stories produced sexual arousal. The hard‐core stories produced significantly greater arousal on the vaginal pressure pulse measure and the subjective report measure. No difference was found on the vaginal blood volume measure.
