We hypothesized that dissimilar mate preferences would augment friendship attraction in zero-acquaintance interactions whereas similar mate preferences would hinder friendship attraction. Heterosexual participants completed an online survey to assess their mate preferences. They also rated the attractiveness of opposite-sex photos. Next, they attended a 3-hr speed-friending session in which they interacted with same-sex others for 3-min each. After each interaction, they completed a 2-min assessment about the person they just met. Two sessions were held, one for women ( N = 20) and one for men ( N = 18). The social relations model was used to regress unique feelings of friendship attraction on similarity in terms of mate preferences while controlling for perceiver and target variance. Our hypothesis was supported among men: Interactions in which two people differed in mate preferences were rated more positively than those in which participants had similar mate preferences. These results are consistent with Parental Investment Theory and highlight the importance of mate preferences in friendship attraction among men.

择偶偏好的差异预示着男性在零熟人时的友谊吸引力，而非女性

我们假设，不同的择偶偏好会增强零熟人互动中的友谊吸引力，而相似的择偶偏好会阻碍友谊吸引力。异性恋参与者完成了一项在线调查，以评估他们的择偶偏好。他们还对异性照片的吸引力进行了评分。接下来，他们参加了一个时长 3 小时的快速交友环节，每人与同性其他人互动 3 分钟。每次互动后，他们都会对刚刚遇到的人进行 2 分钟的评估。举办了两场会议，一场针对女性（N = 20），另一场针对男性（N = 18）。社会关系模型用于将友谊吸引力的独特感受回归到择偶偏好的相似性上，同时控制感知者和目标方差。我们的假设在男性中得到了支持：在择偶偏好不同的两个人的互动中，比在择偶偏好相似的参与者中，评价更积极。这些结果与父母投资理论一致，并强调了择偶偏好在男性友谊吸引力中的重要性。
