| Abstract: | Examined whether 58 male and 47 female undergraduates who were recruited for a study on erotica responded in a similar manner to an erotic film as 29 male and 26 female undergraduates who were recruited for research on a neutral topic, personality questionnaires. In Part 1 of the study, all Ss answered questionnaires, including the Bem Sex-Role Inventory and a sexual opinion survey, that assessed personality and demographic characteristics. In Part 2, Ss watched the erotic movie and completed a feelings scale. Findings indicate that conclusions about prior sexual experience, sexual opinions, and affective responses to the erotic film were qualified by recruitment condition. Ss who volunteered for the experiment on erotica were more sexually experienced and, for women, were significantly more erotophilic than Ss who volunteered for the research on personality questionnaires. Results suggest that volunteer selection can have an important effect on experimental results and demonstrate a method for assessing the extent of these effects.
