在整个人类社会中，人们形成了以强烈的依恋、义务和相互回应为特征的“厚”关系。处于亲密关系中的人会分享餐具，接吻，或进行其他涉及分享唾液的独特互动。我们发现，儿童，幼儿和婴儿推断，分享唾液的二人组（与其他积极的社会互动相反）有一种独特的关系。孩子们希望唾液分享发生在核心家庭中。幼儿和婴儿期望分享唾液的人会在痛苦中相互回应。父母证实，唾液分享是一个有效的线索，关系厚度在他们的孩子的社会环境。因此，使用独特的互动来推断关系类别的能力在生命的早期就出现了，没有明确的教导;这使年轻人能够迅速识别家庭内外的亲密关系。
Across human societies, people form “thick” relationships characterized by strong attachments, obligations, and mutual responsiveness. People in thick relationships share food utensils, kiss, or engage in other distinctive interactions that involve sharing saliva. We found that children, toddlers, and infants infer that dyads who share saliva (as opposed to other positive social interactions) have a distinct relationship. Children expect saliva sharing to happen in nuclear families. Toddlers and infants expect that people who share saliva will respond to one another in distress. Parents confirm that saliva sharing is a valid cue of relationship thickness in their children’s social environments. The ability to use distinctive interactions to infer categories of relationships thus emerges early in life, without explicit teaching; this enables young humans to rapidly identify close relationships, both within and beyond families.
