AbstractThe purpose of this study was to evaluate three sets of predictors of attitudes toward homosexuality: (a) anti‐black and orthodox religious attitudes, (b) sexual permissiveness, and (c) the effect of an introductory human sexuality course. Significantly more positive attitudes were expected for those holding more positive attitudes toward blacks and those who were more sexually permissive. A negative relationship was expected for those holding orthodox religious attitudes. Furthermore, information from a college course in human sexuality was expected to produce positive attitude change toward homosexuality. A survey instrument consisting of several scales and indexes measuring the aforementioned variables, as well as several indexes of sexual behavior, was administered to 194 students in a human sexuality course and 120 students in an introductory psychology course. Results showed significant regression coefficients for anti‐black attitudes and religious orthodoxy, confirming the predictions. Sexual permissiveness did not significantly add to the prediction of attitudes toward homosexuality, although the Pearson correlation was significant,r= .19 (p<.05). The experimental group showed significantly greater change in attitude toward homosexuality than the control group,F(1, 291) = 23.70,p<.001. A fourth objective was to assess sex differences on a series of sexual behavioral indexes. Results show a number of significant differences suggesting that sexual behavior still reflects a double standard in U.S. society.
