Expectant moms who coo and chat to their babies while they’re pregnant may be doing more than stimulating the fetus – they may be shaping their child’s brain, according to research published Monday.
A study in the Proceedings of the National Academy of Sciences reinforces what many people had believed—babies hear what their moms say and their brains recognize these words after birth.
Researchers at the University of Helsinki in Finland looked at 33 moms-to-be, and examined their babies after birth. While pregnant, 17 mothers listened at a loud volume to a CD with two, four minute sequences of made-up words (“tatata” or “tatota”, said several different ways and with different pitches) from week 29 until birth.
The moms and babies heard the nonsense words about 50 to 71 times. Following birth, the researchers tested the all 33 babies for normal hearing and then performed an EEG (electroencephalograph) brain scan to see if the newborns responded differently to the made-up words and different pitches.
Babies who listened to the CD in utero recognized the made-up words and noticed the pitch changes, which the infants who did not hear the CD did not, the researchers found. They could tell because their brain activity picked up when those words were played, while babies who didn’t hear the CD in the womb did not react as much.
