While in womb, babies begin learning language from their mothers

January 2, 2013 in Psychology & Psychiatry

Babies only hours old are able to differentiate between sounds from their native language and a foreign language, scientists have discovered. The study indicates that babies begin absorbing language while still in the womb, earlier than previously thought.

Sensory and brain mechanisms for hearing are developed at 30 weeks of , and the new study shows that unborn babies are listening to their mothers talk during the last 10 weeks of pregnancy and at birth can demonstrate what they've heard.

"The mother has first dibs on influencing the child's brain," said Patricia Kuhl, co-author and co-director of the Institute for Learning & Brain Sciences at the University of Washington. "The vowel sounds in her speech are the loudest units and the fetus locks onto them."

Previously, researchers had shown that newborns are born ready to learn and begin to discriminate between sounds within the first months of life, but there was no evidence that language learning had occurred in utero.

"This is the first study that shows fetuses learn prenatally about the particular speech sounds of a mother's language," said Christine Moon, lead author and a professor of psychology at Pacific Lutheran University in Tacoma, Wash. "This study moves the measurable result of experience with speech sounds from six months of age to before birth."

The results will be published in an upcoming issue of the journal Acta Paediatrica.

Forty infants, about 30 hours old and an even mix of girls and boys, were studied in Tacoma and Stockholm, Sweden. While still in the nursery, the babies listened to vowel sounds in their native tongue and in foreign languages.

Their interest in the sounds was captured by how long they sucked on a pacifier that was wired into a computer measuring the babies' reaction to the sounds. Longer or shorter sucking for unfamiliar or familiar sounds is evidence for learning, because it indicates that infants can differentiate between the sounds heard in utero.

In both countries, the at birth sucked longer for the than they did for their native tongue.

The researchers say that infants are the best learners, and discovering how they soak up information could give insights on lifelong learning. "We want to know what magic they put to work in early childhood that adults cannot," Kuhl said. "We can't waste that early curiosity."

This is junk science at it's best. The indexes used to establish data may not have anything to do with the contention put forth, and the practical implications are really meaningless.

Congratulations go to the researchers and their research.
(For moving the goal posts for sound from postnatal to prenatal.)

Well, almost.

The cells' activity (mutual neuronal exchange of biochemical signals) (like all cells) of developing (human) life shows that one's OWN cells has first "dibs" on influencing the embryonic and developing fetal brain.

No one will ever contend that any living cell is "noiseless"(without neuronal activity.)

So the first 'sound' you will 'hear' is the 'noise' (the back and forth mutual neuronal signal exchange between a future brain and ear.)

Without this (internal) cell 'ground state' mutual neuronal exchange loading the network between a future fully functional brain and future fully functioning 'ear' a brain is left without...

Still. The researchers are to be congratulated for moving the goal posts. There is a whole world the meets more than the eye.

In the womb.
