Evolutionary medicine proposes studying alcohol use and abuse through the lens of modern evolutionary theory. This study (https://osf.io/p48uw/) follows this approach and uses an evolutionary framework to predict how young adults (18–35 years old) form impression of a binge drinker. We predicted that displaying sexual dysfunctions (short-term risk) in a binge drinking video would negatively influence attitudes and expectations of a target when compared to cognitive (short-term risk) or long-term deficits. In the following studies, we use a Zahavian framework to understand and influence impression formation of a male binge drinker among women (intersexual selection) and men (intrasexual competition) participants in a subsequent task. Via a randomized experimental online study in France (N = 177, M = 23.39 [4.91], 43.50% men) and a preregistered conceptual replication study in Peru (N = 176, M = 25.61 [4.76], 53.41% men), women exposed to a binge drinking video—describing sexual impotence after a binge drinking episode—tended to downgrade attractiveness evaluation of the binge drinker. However, male participants were not impacted by the different types of signals displayed in the videos. These results show that evolutionary theory could help us understand impression formation in binge drinking context and call for gender-specific health messages.

酗酒印象形成的进化方法：法国和秘鲁的跨文化比较。

进化医学建议通过现代进化理论的视角来研究酒精的使用和滥用。这项研究 (https://osf.io/p48uw/) 遵循这种方法，并使用进化框架来预测年轻人（18-35 岁）如何形成对酗酒者的印象。我们预测，与认知（短期风险）或长期缺陷相比，在暴饮暴食视频中展示性功能障碍（短期风险）会对目标的态度和期望产生负面影响。在接下来的研究中，我们使用 Zahavian 框架来理解和影响后续任务中女性（间性选择）和男性（内性竞争）参与者中男性酗酒者的印象形成。通过法国的一项随机实验在线研究（N = 177，M = 23.39 [4.91]，43.50% 男性）和秘鲁的一项预先注册的概念复制研究（N = 176，M = 25.61 [4.76]，53.41% 男性），女性观看暴饮暴食视频（描述暴饮暴食后性无能）往往会降低对暴饮暴食者的吸引力评估。然而，男性参与者并未受到视频中显示的不同类型信号的影响。这些结果表明，进化理论可以帮助我们理解酗酒环境中印象的形成，并呼吁针对特定性别的健康信息。
