Toddler Babble May Be Stand-Ins for Grammatical Words
The squeaks and puffs that babies and young toddlers make may actually be their way of imitating actual grammatical words, according to a new study that recorded tens of thousands of sounds made by French-speaking children between 23 and 37 months of age. The findings could have implications for how researchers understand language development and delays, and how they treat it. More from LiveScience:
“Many of the toddlers we studied made a small sound, a soft breath, or a pause, at exactly the place that a grammatical word would normally be uttered,” [Newcastle University researcher Cristina] Dye said in a statement.
“The fact that this sound was always produced in the correct place in the sentence leads us to believe that young children are knowledgeable of grammatical words. They are far more sophisticated in their grammatical competence than we ever understood.”
Though Dye was studying French-speaking toddlers, she and her colleagues expect their findings to apply to other languages as well. She also thinks their results could have implications for understanding language delay in children.
“When children don’t learn to speak normally it can lead to serious issues later in life,” Dye said in a statement. “For example, those who have it are more likely to suffer from mental illness or be unemployed later in life. If we can understand what is ‘normal’ as early as possible then we can intervene sooner to help those children.”
Previous research has shown that toddlers, before they articulate full sentences themselves, may be able to understand complex grammar. A 2011 study published in the journal Cognitive Science found that as early as 21 months, children could match made-up verbs with pictures that made sense grammatically. For example, if they were told “The rabbit is glorping the duck,” they would point to a picture of a rabbit lifting a duck’s leg rather than the duck lifting its leg on its own.
