Why baby’s first words are ‘dada’ or ‘mama’?

After the great research on the new born baby’s brain, it has been concluded that they remember certain repeated words patterns, thus “Daddy” and Mommy,” which they get to hear, really often are mostly the first words they speak.

University of British Columbia post-doctoral fellow Judit Gervain and a team of researchers from Italy and Chile used the latest optical brain imaging techniques, to review the brain activities of 22 newborns. They did it by exposing these little babies to a recording of made-up words.

The researches has mixed the words without repeating syllables  like “mubage”and “penaku” with words having repeated syllable such as “mubaba” and “penana.”

The researchers found that infants had an increase in the activity in the temporal and left frontal areas of their brain when they were exposed to words which were repeated again and again as compared to words which were not repeated often.

Gervain who is  from UBC Dept. of Psychology’s Infant Studies Centre said, “It’s probably no coincidence that many languages around the world have repetitious syllables in their ‘child words’ - baby and daddy in English, papa in Italian and tata (grandpa) in Hungarian, for example.”

Gervain further said, “The language centre of most right-handed adults is located on the left side of the brain. This is consistent with our finding with new born babies and supports our belief humans are born with abilities that allow us to perceive and learn our mother tongue systematically and efficiently.”

The brain areas that are responsible for language in an adult do not ‘learn’ how to process language during development, but rather, they are specialized - at least in part - to process language from the start,” added Gervain.

Proceedings of the National Academy of Sciences online Early Edition will see the publishing of this recent study.
