ABSTRACT

Disgust specific to sexual stimuli has been thought to be an adaptation that serves purposes of pathogen-avoidance, partner selection and social dominance. While the link between disgust responses and homonegative and transnegative attitudes has been relatively established, it is not yet clear why. Literature using evolutionary psychology perspectives of these phenomena is scarce in areas with substantial LGBT-related violence like Colombia. This research aimed to study the interplay of predispositional (e.g. sociodemographic, reported contact), affective (e.g. disgust sensitivity) and cognitive (e.g. Right-Wing Authoritarian) variables in homonegative and transnegative attitudes of Colombian adults. Participants (N = 272) had a mean age of 26.38 (SD = 9.47), women comprised 72% of the sample and men 28%. Hierarchical regression analyses showed that increased sexual specific disgust sensitivity and greater RWA predicted stronger homonegativity and transnegativity. The relationship between sexual disgust and prejudice was partially mediated by RWA. Findings suggest that sexual disgust sensitivity adaptations in homonegativity and transnegativity may respond to selection pressures that differ from pathogen-avoidance perspectives, and that are associated with maintaining social hierarchy and social dominance. Anti-prejudice initiatives would benefit from targeting emotional responses of sexual disgust, especially within communities and institutions that have historically endorsed conservative and traditional values.

摘要

对性刺激特有的厌恶被认为是一种适应，可用于避免病原体、选择伴侣和控制社会。虽然厌恶反应与同性恋和跨性别态度之间的联系已经相对确定，但尚不清楚原因。在像哥伦比亚这样存在大量 LGBT 相关暴力的地区，使用这些现象的进化心理学观点的文献很少。本研究旨在研究易感性（如社会人口统计学、报告的接触）、情感（如厌恶敏感性）和认知（如右翼专制）变量在哥伦比亚成年人的同性恋和跨性别态度中的相互作用。参与者 (N = 272) 的平均年龄为 26.38 ( SD = 9.47)，女性占样本的 72%，男性占 28%。分层回归分析表明，增加的性特异性厌恶敏感性和更大的 RWA 预示着更强的同负性和跨负性。性厌恶和偏见之间的关系部分由 RWA 调节。研究结果表明，同性负性和跨性性中的性厌恶敏感性适应可能会对不同于病原体回避观点的选择压力作出反应，并且与维持社会等级和社会支配地位有关。针对性厌恶的情绪反应将有助于反偏见举措，尤其是在历来支持保守和传统价值观的社区和机构内。
