While infants may seem out of the loop until they starting speaking, researchers at The University of Edinburgh in Scotland say that babies are capable of recognizing word combinations and phrases long before they ever utter their first word.
Indeed, according to Study Finds, their recent research—conducted with some support from academics at Hebrew University of Jerusalem— has revealed that 11- to 12-month-old infants, who are on the verge of speaking, already are processing and understanding various “multi-word phrases” such as “clap your hands.”
This is a breakthrough—representing the first time that investigators have demonstrated that young infants are capable of recognizing and understanding conversations before they begin speaking, themselves. Moreover, this work disputes the long-held belief that babies generally learn languages by first understanding individual words and moving on to sentences. This new study suggests babies learn words and phrases simultaneously.
“Previous research has shown that young infants recognize many common words. But this is the first study that shows that infants extract and store more than just single words from everyday speech. This suggests that when children learn language, they build on linguistic units of varying sizes, including multiword sequences, and not just single words as we often assume,” says Dr. Barbara Skarabela from the School of Philosophy, Psychology, and Languages Sciences, in a university release.
What’s more, Study Finds reports, the researchers also say these findings may provide an explanation as to why adults have so much trouble becoming bilingual.
“This may explain why adults learning a second language, who tend to rely on individual words, often fall short of reaching native-like proficiency in the way they string words together into phrases and sentences,” Dr. Skarabela adds.
Researchers studied 36 babies during this project, via a series of “attention tests” featuring recorded audio from adults. Study authors watched closely as the babies listened to the recordings and looked out for any signs of understanding or acknowledgment. All of the recorded phrases only featured three words and many were consistent with a typical “conversation” between infants and adults.
The team then assessed infant responses and compared them using a method called central fixation. This approach allowed researchers to measure the babies’ looks and eye glances in response to the recordings. Using this strategy, they successfully determined when a baby recognized a familiar phrase like “clap your hands” in comparison to a sentence they had likely never heard before—such as “take your hands.”
