What are baby’s first words spoken?
What are the first few words you said when you was a baby or what will be your baby’s first few words? Of course you will guess “Mummy”, “papa”, “Daddy”, “mom” and other such words. Why it is so? A recent Canadian study shows why these are the only first words new-born babies understand.
Led by Judit Gervain of Vancouver’s University of British Columbia, her team conducted their research on 44 newborn babies. Using the latest optical brain imaging techniques, they exposed the babies to the recordings of made-up words and then documented brain activities
Their reports stated that babies are born with an innate ability to recognize these words. It concludes that the human brain is hard-wired to recognize certain repetition patterns and decipher languages.
The study published in the current issue of the Proceedings of the National Academy of Science’s online Early Edition revealed that the babies are divided into two groups to carry out two sets of experiments. They are exposed to about 22 minutes of recordings of the above-mentioned words.
It was found that whenever the repetitious words were played, the temporal and left frontal areas of the newborns’ brain shows increased brain activities. Words with non-adjacent repetitions elicited no distinctive responses from the brain.
“While they were exposed to the recordings, we monitored the oxygen levels in blood in their brain areas. We found that when the babies heard the words `papa’, `daddy’, and `mommy’, the blood oxygen level in certain brain areas went up. It showed those brain areas became active on hearing these words (papa, mommy), and thus needed more oxygen,” she added
This is one of the first studies on a newborn infant’s innate ability to decipher structural patterns in language.
