Study: Babies show preference for native language

July 17, 2007


— Children as young as 5 months old exhibit preferences for their family's unaccented native language, researchers reported this week, suggesting that speech makes a powerful first impression even very early in life.

"Babies want to interact with somebody who speaks the language they are familiar with, even though the babies themselves don't speak yet," said Katherine Kinzler, an author of the paper being published today in the journal Proceedings of the National Academy of Sciences.

Infants not only looked more often at a person who spoke their native tongue without an accent, they were more likely to accept toys from those people, the study found. Five-year-old children were more likely to desire friendship with children who spoke the same language and those without an accent.

Such early preferences may develop into criteria for making judgments about strangers, in the same way that race and gender color people's perception, the authors speculate.

In the study, American infants were shown videos of women speaking either English or Spanish. The babies were then shown both women side by side and silent, and researchers measured how long the infant spent looking at each face.

The authors observed a preference for looking at the woman who spoke English.

However, most previous studies using this "looking-time" task were unable to determine whether the infant preferred one of the choices or if it drew the infant's attention for another reason, said Mark Liberman, a professor of linguistics at the University of Pennsylvania who was not involved in the study.

"In most uses of the technique, the only conclusion that you want to draw is that the infants can tell the difference," Liberman said.

To address this concern, the researchers added a behavioral choice to the experiment. Slightly older infants who were not yet talking again viewed women speaking two different languages, followed by a video of each speaker offering the child an identical toy.

When the toys were actually presented to the children in front of the two images of the speakers, they chose the one "offered" by the native speaker more often.

Although the current study looked only at children from monolingual households, the early formation of language preferences raises the possibility that exposure to more than one language early in life may weaken these biases.

"It's an open question how malleable these early preferences are, and how exposure to multiple languages might mitigate those preferences," said Kinzler.

I heard that babies prefer people who sound like they're talking through amniotic fluid and flesh. Mumble at'em. They love it! They love it even more if you talk with your mouth full, but wonder why their blood sugar isn't rising. I know...CRAZY. You can't make this stuff up! I can, though.
