Children expect saliva sharing to happen in nuclear families. Toddlers…

Children’s Expectations and Understanding of Kinship as a Social Category
- PsychologyFront. Psychol.

3- and 4-year-old children failed to show either robust explicit conceptual distinctions between kin and friends, or expectations of behavior favoring kin over friends, even when asked about their own social partners, which suggests that explicit understanding of kinship develops slowly over the preschool years.
Preverbal Infants Infer Third-Party Social Relationships Based on Language.
- PsychologyCognitive science
- 2017
Infants were familiarized with videos of two people who spoke the same or different languages, and then viewed test videos of those two individuals affiliating or disengaging to suggest whether 9-month-olds use the language a person speaks as an indicator of that person's likely social relationships.
