Newborn babies have an innate ability to pick out individual words from speech, according to a study which provides a key insight into the first step in language learning.
Researchers from the University of Manchester in the UK and colleagues discovered two mechanisms in three-day-old infants, which give them the skills to pick out words in language.
The study, published in the journal Developmental Science, describes two new mechanisms which allow us to recognise when a word starts and stops.
One of the mechanisms is known as prosody -- the melody of language -- while another is called the statistics of language, which describes how we compute the frequency when sounds in a word come together.
"That's quite important for new parents and gives them some insight into how their baby is listening to them," Ferry said.
"We often think of language as being made up of words, but words often blur together when we talk. So one of the first steps to learn language is to pick out the words," Flo said.
"Our study shows that at just three days old, without understanding what it means, they are able pick out individual words from speech.
"And we have identified two important tools that we are almost certainly born with, that gives them the ability to do this," she said.
The researchers played the infants a three and a half minute audio clip in which four meaningless words were buried in a stream of syllables.
Using a painless technique called Near-Infrared Spectroscopy, which shines light into the brain, they were able to measure how much was absorbed, telling them which parts of the brain were active.
"We then had the infants listen to individual words and found that their brains responded differently to the words that they heard than to slightly different words," said Perrine Brusini of the University of Liverpool in the UK.
"This showed that even from birth infants can pick out individual words from language," Brusini said.
