Babies' brains sync with strangers via dad's scent, Science Advances study finds
rickasaurus · x · 2026-10-06
A new Science Advances study found that when babies interact with an unfamiliar man, the presence of their father's body odor (vs. a clean shirt) increases brain synchrony between baby and stranger and boosts positive engagement — as if the baby could 'invoke' the father's presence. Fathers more involved in childcare produced a stronger scent-linked synchrony effect.
