Subjects were 20 volunteers randomly selected from all female undergraduate students attending a local university, who were 21 years of age or older, and living off campus. The stimuli consisted of seven films, of approximately 5 minutes duration each, which depicted various types of human sexual behavior. Themes included "romantic" heterosexual behavior, primarily genital heterosexual behavior, a mild, and an explicit form of group-sex behavior, a mild and explicit form of heterosexual sadomasochistic behavior, and male homosexuality. Subjects rated the degree of sexual arousal experienced for each film on a 50-point Likert scale. The order of presentation of the films for each subject was randomized, and all subjects participated individually with only a female experimenter present. Following the rating period, subjects completed the Sex Knowledge and Attitude Test (9). Finally, a structured interview was conducted to probe specific likes and dislikes with respect to the content of the films viewed. Results indicated that rank order ratings of the films, from most to least sexually stimulating, was: heterosexual, romantic; group-sex mild (two males and one female); heterosexual-genital; group-sex explicit (three males and three females); sadomasochism (mild); sadomasochism-explicit (forcing and brutal); and male homosexuality. One conclusion that the data led to was that females preferred and were significantly more sexually stimulated by films in which a male related to a female (even if the male was treating the female cruelly) than they were by homosexual stimuli involving two males together. Correlational data between the rating responses and the Sex Knowledge and Attitude Test yielded much information including significant negative correlations between ratings of both group-sex films and rejection of sexual myths. Also, significant positive correlations were found between rated degree of sexual stimulation for the heterosexual and the group-sex films and the consideration of pre- and extramarital relations as acceptable or even desirable.
研究对象是从当地一所大学所有21岁及以上、不住校的本科女生中随机挑选出的20名志愿者。刺激物包括七部影片,每部时长约5分钟,描绘了各种类型的人类性行为。主题包括“浪漫”的异性性行为、主要是生殖器的异性性行为、一种温和的和一种露骨的群交行为形式、一种温和的和露骨的异性施虐受虐行为形式以及男性同性恋。研究对象根据50分的李克特量表对每部影片所体验到的性唤起程度进行评分。每一位研究对象观看影片的顺序是随机的,并且所有研究对象都单独参与,现场只有一名女性实验者。在评分阶段之后,研究对象完成了性知识与态度测试(9)。最后,进行了一次结构化访谈,以探究研究对象对所观看影片内容的具体喜好和厌恶之处。结果表明,影片从最具性刺激到最不具性刺激的排名顺序为:异性浪漫的;温和的群交行为(两男一女);异性生殖器性行为;露骨的群交行为(三男三女);轻度施虐受虐行为;露骨的施虐受虐行为(强迫和残忍);以及男性同性恋。数据得出的一个结论是,女性更喜欢并且在观看男性与女性互动(即使男性对女性很残忍)的影片时比观看涉及两名男性的同性恋刺激影片时受到的性刺激明显更多。评分反应与性知识和态度测试之间的相关数据产生了许多信息,包括两部群交影片的评分与对性神话的否定之间存在显著的负相关。此外,还发现异性恋和群交影片的性刺激评分程度与将婚前和婚外关系视为可接受甚至是可取的观念之间存在显著的正相关。
