Can diversity make babies open-minded learners?

Hearing different languages around the neighborhood—in stores, on the bus, at the park—may turn babies into more open-minded social learners.

While previous research has shown that direct interactions with parents and caregivers shape early cognitive development, the influence of the broader community beyond those direct experiences has not been as carefully examined.

In a new study in the journal Cognition, researchers investigated whether the variety of languages in infants’ neighborhoods affects their willingness to learn from people who are different from them.

“We were interested in linguistic diversity—that is, how many different languages babies might hear,” says lead author Lauren H. Howard, a psychology doctoral student at the University of Chicago.

“All of the babies in our study heard only English from their parents and caretakers. But they lived in neighborhoods where multiple languages were spoken. Our findings showed that hearing those languages outside the home, for example at the park or on the bus, made infants more open to learning from someone who did not speak English,” Howard adds.

“Research has shown that children, like adults, are often biased against interacting with and learning from people who are different from them,” explains Amanda Woodward, professor of psychology and an expert in social cognition during infancy and early childhood.

“In this new study, we found that these fairly young babies are tuning into the social world outside of their home environment. The exposure to diversity may help protect against the development of a bias very early in life,” Woodward says.

Learn and imitate

The researchers analyzed data from four experiments investigating 19-month-old infants’ imitation of adults who either spoke the infants’ native language (English) or a different language (Spanish).

All of the 82 children were from the Chicago and Washington, DC metro areas, and were exposed only to English in their own households. Howard says she and her colleagues used US Census Bureau data to identify the prevalence of non-English languages present in the infants’ neighborhoods.

The experiments used various ways to test how well the infants could learn new tasks from a non-English speaker.

One set of infants observed an English-speaking or a Spanish-speaking adult perform actions on a series of toys to attain a goal. For example, the adult would press a button to turn on a light or open a box to get a fun toy from inside. The adults spoke different languages, but relied on visual demonstration to show how to perform the task.

A second group of infants saw both the English and Spanish speakers side-by-side performing different actions on the same toy to obtain a similar goal. For example, one experimenter might turn on a light with her head and the other would use an elbow. After a brief delay, the infants were allowed to act on each toy.

The researchers then assessed the infants’ propensity to imitate one experimenter over another. They found that infants who heard a diversity of languages in their home neighborhoods were more likely than infants from less diverse areas to take cues from the Spanish-speaking adults.

“Both experimenters were providing useful information to the babies—’how does this object work?’ But they were not using language to explain what they were doing, just demonstrating,” Howard says. “And babies from more diverse communities learned and imitated more of the Spanish speaker’s actions.”

Neighborhood diversity

Woodward says the findings could have implications for how neighborhoods affect children’s general willingness to engage with people of other backgrounds as they grow older.

“This study provides evidence that infants’ social learning is shaped by the diversity of the neighborhood in which they live, even if they do not have direct interaction with people who speak other languages,” says Woodward.

“This exposure to diversity might reduce the risk of developing bias, and may keep children open to opportunities to learn from and interact with diverse social partners.”
