Babies cry in their mother tongue – Scientists claim

Baby’s cry could help spot Language disorders babyThe researchers recorded the crying of 55 new born babies from Peking and 21 from Cameroon. The babies were only recorded when they cried spontaneously, like when they were hungry. At first the researchers thought their results in the Nso could be due to their cultural background. Children are born in rural settings where there is little access to modern technology. The babies in Peking, however, were exposed to modern technology like radio, television and mobile phones from a young age. ‘The fact that despite these cultural differences both tonal language groups exhibited similar effects in comparison with the non-tonal German group indicates that our interpretation of data points in the right direction,’ said Professor Wermke. She said the results could also be used to help identify children who may be suffering from language disorders from an early age. By looking for key signatures in their cry, it could help to reveal how a baby’s language development is going.

The researchers, whose work is published in two papers in the journal Speech, Language and Hearing, and the Journal of Voice, examined the crying of infants of the Nso. They found these babies cried with greater pitch variation than the children of German-speaking mothers. The rise and fall of tones during crying was also more intensive in the Nso children. The researchers also found similar results in children from Peking, but to a lesser degree. The Nso use a complex tonal language that uses eight different tones to give meaning to words but also have specific fluctuations in pitch to alter the meaning of certain sounds further. The scientists say their findings indicate that babies begin learning languages far earlier than previously thought. Baby babble, for example, was thought to be important in language development in young children. But the new work suggests this process may even begin while children are in the womb in a process known as maternal imprinting. There may also be some genetic effects, the researchers say. Professor Wermke said: ‘The building blocks for the development of the future language are acquired from the moment of birth and not only when infants begin to babble or to produce their first words.’ Source Daily Mail]]>
