Spit swap

It's time to Kiss and Tell! From firsts to worsts, we're talking swapping spit all Valentine's week long. In this installment, Alli Maloney explores the science of kissing. Kissing is the end to many stories we tell, a passionate moment when two meant-to-be people realize their love — an action driven by romance. We dream of our first and dread our last and, when deemed bad, move along quickly. But why put our mouths together as a way to show affection? Is kissing something humans learned, or an instinct? And does everyone around the world do so? While nuzzling, face-touching, and other kissing-type behaviors are common among mammals, humans are the only species that intentionally touch lips — with the exception of our closest relatives, bonobos and chimps, who perhaps do so for other reasons like reconciliation or grooming. Those who study the science of smooching, or encoded philematology, say that the reason humans kiss is still up for debate despite decades of research. It may be an innate, subconscious move encoded in our genes through evolution, or a human invention.

A new study by Harvard and MIT researchers, including psychologist Elizabeth Spelke , shows that children as young as 8 to 10 months old infer two people are likely in a close relationship if they see them having interactions that involve a transfer of saliva. The study indicates that babies understand all of these activities as social cues indicating whether people are on casual terms or share stronger bonds. The research, published in Science, also suggests babies glean from such gestures whether those involved are likelier to comfort one another if something stressful comes up — say, if one of them starts crying. Lead researcher Ashley Thomas says the experiments involved fuzzy puppets, orange slices, and saliva-dipped fingers and were performed under the watchful eyes of infants and toddlers, ranging from 8 to 18 months of age. In one set, a woman took a bite of an orange slice then placed it in the mouth of a fuzzy blue puppet before taking it back for another nibble.

January 20, at pm. Young children are always watching. That includes when people swap spit through actions like sharing food — helping the tots work out who is in close relationships with one another, a study suggests. Typically, people are more likely to share things that can lead to an exchange of saliva, such as kisses or an ice cream cone, with family members or close friends than with an acquaintance or colleague. So to see if kids, including babies and toddlers, might use saliva sharing as a cue for intimate bonds, Thomas and colleagues turned to experiments of people engaging with puppets. But tracking where they look is one way to get a hint. The idea is not that young children might be expecting an adult to comfort the puppet, Thomas says. Instead, the researchers expected that the young children would look toward the person that they expect to move first when the puppet expresses distress, and that would be the person who has a closer relationship with the toy, she says. For some of the experiments, the team showed 8- to month-old babies or to month-old toddlers videos of a woman sharing an orange slice with a puppet.
