Babies May Remember Words Heard Before Birth

 If you mood then telling off your fetus in the womb, a supplementary examination suggests you should: The research finds that babies manufacture a memory of words they hear frequently by now they are born.

"We receive this shows how adeptly the brain at this age adapts to sounds. It is a sign of totally in the future language learning, or adaptation to the sounds they heard," said investigation co-author Minna Huotilainen, a docent at the University of Helsinki's Finnish Center of Excellence in Interdisciplinary Music Research. "A newborn baby is not an blank canvas, but has already studious how his or her mother and adding in the works relatives members speak."


It may hermetic amazing that babies can recall sounds they heard in the womb, especially when their brains are still developing the connections that manage to pay for in them to process all at all. Still, there are signs that fetuses actually recall sounds they deed.

"There is already some evidence that fetuses can learn, and that babies can remember songs or passages of speech from the fetal era," Huotilainen said.

The researchers tested the memory of Finnish fetuses by exposing them to a single word -- "tatata" -- that means nothing in the Finnish language.

"It is a so-called 'pseudoword' that is important for research. It has three syllables, and we chose such a long word to make it challenging for the small brains to locate the changes and offer them something hard to learn," Huotilainen said. "Such a word could exist in Finnish. It follows all the rules of the Finnish language."

From the 29th week of pregnancy until birth, about half of the 33 pregnant women in the examine listened to recordings of the word repeated hundreds of times. Sometimes the recordings presented the word once a swing centre syllable ("to") or pronounced differently.

After birth, the researchers used scans to test the be in pain in the brains of all the babies following they heard the word. Those who'd heard it by now "showed an enhanced greeting to this specific word," Huotilainen said. "They were sprightly to process the word bigger, and in addition to they were able to detect changes in the word bigger."


Huotilainen said it appears that the type of learning revealed by the psychiatry probably happens in the late allocation of pregnancy, although this hasn't been studied. Babies begin to hear more or less halfway through pregnancy, she said.

Patricia Kuhl, a speech moot and director of the University of Washington's NSF Science of Learning Center, praised the psychotherapy. "The fact that learning from frequently presented sounds occurs even if infants are still in the womb means that language learning does not begin in the region of Day 1 at the moment of birth, but even though the infant listens to sounds in utero. It's in fact quite amazing that the fetal brain has that gaining."

What can parents realize when this quality?

"Be au fait that the fetus can hear something from the outside world and learn from it," psychotherapy co-author Huotilainen said. "Speak during your pregnancy. You can speak to new people or to your fetus if you in imitation of."


The psychotherapy appears in this week's issue of the journal Proceedings of the National Academy of Sciences.
