FULL STORY

Infants may be more sensitive to non-native speech sounds than previously thought, according to a study published in theJournal of Memory and Language. The findings shed light on the way babies begin to understand language.

The study, coauthored by Jessica Hay, an associate professor in the University of Tennessee, Knoxville's Department of Psychology, and Ryan Cannistraci, a PhD student in experimental psychology, looks at how lexical tones can affect an infant's ability to associate words with objects.

Lexical tone is the manipulation of a word's pitch contour. Although English words do not make use of pitch contours within words to convey meaning, many languages -- such as Mandarin Chinese, Cantonese, and Thai -- do.

For example, by changing the pitch contour, the Mandarin word ma can mean either "mother," "horse," "hemp," or "to scold."

What differentiates Hay and Cannistraci's study from others in the field of infant language learning is its focus on these non-English sound structures.

"Most research on early word learning has focused on what is referred to as intonation languages, where pitch changes are used at the phrase level but not to mark changes in word meaning," Hay said. "However, over half of the world's languages use pitch contours to communicate meaning."

The researchers based their experiments on a cognitive skill called task switching -- the ability to unconsciously shift attention between different tasks. The research involved presenting 14-month-old subjects with two novel objects paired with a novel pseudoword. The babies had English as their primary household language.

In the "switch" trials, the labels were reversed. By measuring average attention for both trial types, researchers were able to gauge whether the subjects had truly learned the object-label association. It may seem intuitive that the infants would have an easier time discerning between two objects when the labels differ greatly in tone, but this is not always the case.

In fact, the researchers found that the babies were able to learn the association between an object and its label more easily when they heard a sound with a high-pitch contour, just as babies that have Chinese as a primary household language would hear.

"We think it may be the case that English-learning infants are able to learn from the rising pitch contour in our experiment because they hear rising pitch contours in their everyday life," Cannistraci said. "In English, rising pitch contours are prevalent in infant-directed speech, and are also often used to solicit attention and to mark questions."

The experiments pave the way for a more inclusive approach to understanding how language is learned.

"In order to be able to generalize what we know about how children learn languages, it is important to study all sorts of different languages," Hay said. "By incorporating non-native lexical tones into our studies, we have learned that infants are able to apply what they know about their own language when learning words in a new language. This suggests that infants are motivated to learn language and will use any potentially relevant information available to them."
