Several distal and proximal processes have been implicated in sexual aggression (SA) perpetration, including sexual misperception, or the erroneous perception of a potential partner's sexual interest or consent, alcohol intoxication, and past perpetration. Little is known about how these predictors interact in the context of a sexual interaction. Thus, the present study aimed to investigate how men's perceptions of a woman's sexual interest changed over the course of a hypothetical sexual interaction and how their intoxication, past perpetration and the woman's consent cues influenced those perceptions.
Single, male social drinkers aged 21-30 with a history of risky sexual behavior (N = 97) completed an alcohol administration paradigm in which they were randomly assigned to an alcohol condition (sober control vs. intoxicated [BrAC = 0.10%]). Participants read a hypothetical scenario in which a man and woman engaged in nonpenetrative sex and the woman expressed nonconsent nonverbally and verbally. At several points during the scenario, participants rated the woman's sexual interest. Participants also reported their past perpetration.
Men's perceptions of the woman's sexual interest significantly decreased following verbal expressions of nonconsent. There were no significant differences between intoxicated and sober participants' ratings of the woman's sexual perception following verbal expressions of nonconsent. Men with a history of perpetration rated the woman's sexual interest following multiple verbal expressions of nonconsent as higher than nonperpetrators.
Results suggest that intoxication does not necessarily impede men's ability to adjust their perceptions of a woman's sexual interest following verbal expressions of nonconsent.
性侵犯（SA）的实施涉及多个近端和远端因素，包括性误解，即对潜在伴侣的性兴趣或同意的错误认知、酒精中毒以及既往犯罪史。对于这些预测因素在性互动背景下如何相互作用，人们知之甚少。因此，本研究旨在调查男性对女性性兴趣的认知在假设的性互动过程中如何变化，以及他们的醉酒状态、既往犯罪史和女性的同意线索如何影响这些认知。
97名年龄在21至30岁之间、有危险性行为史的单身男性社交饮酒者完成了一项酒精给药范式，他们被随机分配到酒精条件组（清醒对照组与醉酒组[呼气酒精含量=0.10%]）。参与者阅读了一个假设场景，其中一名男性和一名女性进行了非插入式性行为，并且女性通过言语和非言语表达了不同意。在场景中的几个时间点，参与者对女性的性兴趣进行了评分。参与者还报告了他们过去的犯罪行为。
在女性通过言语表达不同意后，男性对女性性兴趣的认知显著下降。在女性通过言语表达不同意后，醉酒和清醒参与者对女性性认知的评分没有显著差异。有犯罪史的男性在女性多次通过言语表达不同意后，对女性性兴趣的评分高于无犯罪史者。
结果表明，醉酒并不一定会妨碍男性在女性通过言语表达不同意后调整其对女性性兴趣认知的能力。
