Babies as young as 9 months old know that friends usually have similar interests, new research suggests.
The new study, published online January in the
Journal of Experimental Psychology: General, shows that babies who are too young to talk still have a set of abstract expectations about the social world.
"Nine-month-old infants are paying attention to other people's relationships," said study co-author Amanda Woodward, a psychology professor at the University of Chicago. "Infants are able to watch two strangers interact in the movie and then make inferences about whether those two people are likely to be friends," said Woodward, referring to a movie showed to the babies during the experiment.
Baby brainiacsBehind their wide-eyed, innocent facades, babies possess a surprising grasp of how the world works.
Infants are born wired with a primitive number sense, have an innate grasp of physics and even know that living organisms should have guts.
They also have expectations about people's interactions. From a young age,
babies know that might-makes-right, and want justice meted out to wrongdoers. By a year-and-a-half, many little ones can guess what people are thinking.
But researchers didn't know what babies knew or thought about friendship. Drawing from an assumption many adults hold - that
friends have similar interests - Woodward and her colleagues wanted to see whether babies also had a buddies-think-alike intuition.
