Researchers call the special way we talk to babies ‘motherese’ or ‘parentese’. They have found that infants prefer to hear parentese to grown-up conversation.
Think of the last time you met a baby in the company of an adult. Chances are your conversation went something like this:
Researchers call the special way we talk to babies ‘motherese’ or ‘parentese’. This sing-song speech, often accompanied by exaggerated facial expressions, seems to be used by nearly everyone who talks to a baby. We all love to do it – mothers, fathers, grandparents, friends, even preschoolers addressing younger brothers and sisters. And what’s more, babies seem to like it too.
But does parentese serve a purpose beyond making everyone feel warm and happy? Could the elongated vowels, high pitch, exaggerated facial expressions and short, simple sentences of baby talk help infants learn language?
We know babies like it. Researchers have found that infants prefer to hear parentese to adult conversation.
To test this, scientists sat babies in infant seats and let them choose to hear tapes of adult-to-adult speech or adult-to-infant speech. When babies turned their heads one way, an eight-second tape of adult conversation played. When they turned their heads the other way, the babies heard parentese. The researchers found that the babies consistently chose to turn their heads to hear the speech directed toward infants. Amazingly, further testing showed this to be true even when the parentese was in a foreign language.
In fact, researchers have found that babies as young as five months old are capable of some simple lip-reading.
In this test, babies were first shown a silent video of a face forming the sounds ‘ahhh’ or ‘eeee’. Then they heard audiotapes of one of the sounds. The babies knew which face matched which sound. Babies hearing the ‘ahhh’ sound looked at the video with the wide-open mouth, while those that heard ‘eeee’ looked at the video with the grinning mouth.
Researchers are just beginning to look at the possible benefits of parentese. But it’s well established that most of us use it, regardless of our culture or native tongue.
Various studies have documented parentese in speakers of English, German, Russian and Swedish. And one study found it among speakers of Mandarin Chinese, a tonal language in which, unlike English or German, a change in the pitch of a word alters the meaning of that word.
But no matter the language, parentese seems to share several characteristics and, scientists theorise, has several purposes:
That’s easy. Use parentese. And don’t be embarrassed about it for a second. Across the world, adults love baby talk. Babies love baby talk. It’s delightful to move in close to a child and communicate in a warm, friendly way that’s sure to get a smile. And the slow, higher-pitched, sing-song speech might be just what an infant needs to hear to help figure out how language is put together.
