Abstract：
Partner preferences are an important differential in relationship formation and evolutionary fitness, and vary according to individual, ecological, and social factors. In this study, we evaluated the variation in preference for intelligence, kindness, physical attractiveness, health, and socioeconomic level among individuals of different sexes and sexual orientations in a Brazilian sample. We analyzed the preference scores of 778 heterosexual, bisexual, and homosexual men and women in three budgeted mate design tasks (low vs. medium vs. high budget) and their association with sociosexuality, attachment styles, homogamy, and willingness to engage in short- and long-term relationships. Results indicated a global trait preference order, with intelligence ranking first, followed by kindness, physical attractiveness, health, and lastly by socioeconomic status. Typical sex differences were observed mostly within the heterosexual group, and specific combinations of sex and sexual orientation were linked to variation in preference for physical attractiveness, kindness, and socioeconomic status. We also found unique associations of the other variables with partner preferences and with willingness to engage in short- or long-term relationships. By exploring the partner preferences of non-heterosexual individuals from a Latin American country, an underrepresented group in evolutionary psychology research, our results help understand the universal and specific factors that guide partner preferences and human sexual behavior.
摘要：
伴侣偏好是关系形成和进化适合度的重要差异，根据个人的不同，生态,和社会因素。在这项研究中,我们评估了对智力偏好的变化，仁慈,身体吸引力,健康,巴西样本中不同性别和性取向的个体之间的社会经济水平。我们分析了778个异性恋者的偏好得分，双性恋,和同性恋男性和女性在三个预算伴侣设计任务(低与中等vs.高预算)及其与社会性的联系，附件样式,一夫一妻制,并愿意从事短期和长期的关系。结果表明，全球特征偏好顺序，智力排名第一，其次是善良，身体吸引力,健康,最后是社会经济地位。典型的性别差异主要在异性恋群体中观察到，性别和性取向的特定组合与对身体吸引力的偏好变化有关，仁慈,和社会经济地位。我们还发现了其他变量与伴侣偏好以及参与短期或长期关系的意愿之间的独特关联。通过探索来自拉丁美洲国家的非异性恋者的伴侣偏好，一个在进化心理学研究中代表性不足的群体，我们的结果有助于理解指导伴侣偏好和人类性行为的普遍和特定因素。
