Infants May Understand Friendship at 9 Months of Age
Babies as young as 9 months old may have a grasp of the social world that could be described as comprehension of the concept of “friendship,” a new study published in the Journal of Experimental Psychology: General shows. More from LiveScience:
“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….
The researchers had 64 nine-month-olds watch two videos of two actors eating a mystery food from two differently colored containers. Sometimes the actors smiled and said, “Ooh, I like it,” or made faces of disgust and said, “Eww, I don’t like that.” (The team chose to use food, because it plays a central role in many social gatherings with family and friends.)
The two actors either had similar food preferences or opposing ones.
Afterward, the tots watched a video of the two people meeting and either being friendly to one another or giving each other the cold shoulder.
Though infants can’t say what they’re thinking, they reveal their thoughts by what they pay attention to, Woodward told LiveScience. “When they see events that are inconsistent or unexpected, they tend to look at them longer,” she said.
The youngsters stared longer at videos of people with opposing views who were friendly to each other, suggesting the babies expected the two people who disagreed on food to be foes. Infants also stared longer at unfriendly people who still liked the same foods.
The findings suggest that even at a young age, babies expect people with similar likes and dislikes to be friends, and those who disagree to be unfriendly.
Babies may be wired to expect this behavior, Woodward said.
In their short lives, “babies probably didn’t learn this expectation from experience,” Woodward said. “It’s some expectation that they are in some way prepared to have.”
