UW-Madison: How a cat can hinder children learning new words

MADISON – Say you are shown an apple, a banana and a fruit you have never seen before. Then you are asked to pick the “pifo.” Which fruit would you choose?

Chances are you would select the novel fruit. Children often use the same strategy – leveraging their knowledge of familiar objects – to learn new words and connect them with unfamiliar or novel objects by process of elimination. So it might seem that having familiar objects around would help children learn new words.

That’s what researchers thought, too, but a new study directed by University of Wisconsin-Madison psychology professor Jenny Saffran is the first to show that familiar objects can sometimes be a “double-edged sword” – both helping children learn new words and hindering them.

“It’s pretty universally accepted that familiar objects help children learn new words,” says study co-author Ron Pomper, a graduate student in Saffran’s Infant Learning Lab at the Waisman Center. “We show that it’s more nuanced than that.”

Published recently in the journal Child Development, the study found that familiar objects that are more interesting to children – brightly colored ones, or animals or food, for example – distracted them from focusing on novel objects and reduced their ability to learn new words associated with those objects.

This surprised Pomper and Saffran, who were working with children from just older than 3 years to almost 4 – from 38 months to 45 months, to be exact. The Infant Learning Lab studies development among children 6 months to 6 years of age.

“Although they might make it look easy, children are working very hard to learn new words,” says Pomper. “This study shows that not all word-learning opportunities are equal. If a cat walks in, for example, it may not be the best time for a child to be learning new words.”

To further explore whether interesting familiar objects distract children from novel objects, the researchers showed children a pair of images: one of a familiar object, like a cat or a box, and one of a novel object. While the children were looking at the images, they heard a sentence that contained a new word, like, “Find the pifo” or “Where’s the tever?”

Researchers tracked children’s gazes and found that they spent significantly less time looking at the novel object when the familiar object was more interesting, like a cat, compared to when the familiar object was less interesting, like a box.

When the familiar object was more interesting, the children also took longer to shift their gaze to the novel object after hearing the sentence containing new words, like “pifo” or “tever.”
