Monkeys Use ‘Baby Talk’ With Infants
Cayo Santiago, Puerto Rico - A person who excitedly approaches infants and speaks to them in a high-pitched, musical voice has a behavior in common with female monkeys, suggests a new study, which found that female rhesus macaques use "baby talk" when they see another monkey's offspring.
Since "baby talk," also known as "motherese," may be an evolved trait in certain primates, the finding indicates this gentle way of vocalizing could play a key role in promoting positive relationships between parents and babies, as well as between adults and other grown-ups.
