Alcohol and sexual arousal are contextual determinants of condomless sex. Dual-process theory postulates that two types of cognitive processing contribute to the regulation of behavior: one that is fast, intuitive and automatic, and another that is slower and deliberative. This study applied a dual-process model to investigate condomless sexual behavior, highlighting the potential importance of implicit attitudes in condomless sex. We investigated whether the impact of alcohol and sexual arousal on condom use-related attitudes and intentions was explained by diminished working memory capacity, as dual-process models suggest. We also investigated whether this effect could be explained by implicit and explicit attitudes toward condom use. Male participants (N = 30) were randomized using a 2 × 2 within-subjects design that manipulated alcohol intoxication (placebo vs. alcohol beverages) and sexual arousal (neutral vs. erotic movie clips). We measured participants' working memory capacity, intentions to use a condom, and explicit and implicit attitudes toward condom use. Significant main effects of alcohol intoxication and sexual arousal on working memory capacity were found. No significant interaction was found for the combined effect of alcohol intoxication and sexual arousal on intentions to use a condom. There was no significant effect of implicit attitudes on intentions to use a condom, although a trend toward significance (p = 0.06) was found for the effect of implicit attitudes on intentions to use a condom when participants were in a state of alcohol intoxication. Theoretical and practical implications of this study are discussed.
酒精和性唤起是决定无保护性行为的情境因素。双加工理论假设，两种类型的认知加工有助于行为调节：一种是快速、直观和自动的，另一种是较慢和深思熟虑的。本研究应用双加工模型来研究无保护性行为，强调内隐态度在无保护性行为中的潜在重要性。我们调查了酒精和性唤起对与使用安全套相关的态度和意图的影响是否可以用工作记忆容量的降低来解释，这是双加工模型所提出的。我们还调查了这种影响是否可以用对使用安全套的内隐和外显态度来解释。我们使用 2×2 被试内设计随机分配了 30 名男性参与者，该设计操纵了酒精中毒（安慰剂与酒精饮料）和性唤起（中性与色情电影剪辑）。我们测量了参与者的工作记忆容量、使用安全套的意图以及对使用安全套的内隐和外显态度。我们发现酒精中毒和性唤起对工作记忆容量有显著的主效应，但在酒精中毒和性唤起对使用安全套的意图的综合影响上没有发现显著的交互作用。内隐态度对使用安全套的意图没有显著影响，但当参与者处于酒精中毒状态时，内隐态度对使用安全套的意图有一个趋势上的显著影响（p=0.06）。本研究讨论了其理论和实践意义。
