Talking to her baby between the ages of 18 and 24 months with adult words would improve her intelligence quotient and her ability to communicate ten years later, an American study shows.
By analyzing the effects of speech in babies, a team of researchers from several American universities recorded, for six months, all the words spoken in the homes of 146 families with a baby. These words, analyzed with the help of a software, made it possible to calculate the number of conversations between the parents and their children.
Then, years later, the researchers gave language and cognitive tests to children between 9 and 14 years old. The intelligence quotient, verbal comprehension and children’s vocabulary were measured.
In analyzing the results, the researchers noted a correlation between the number of recorded conversations while the babies were between 18 and 24 months and the test scores of the children. These results were 14 to 27% higher, according to the tests, for the children most exposed to the word of their parents.
Researchers also noted a slight improvement in testing for babies aged 2 to 17 months and those 25 months and older, but this was not statistically significant.
The authors of the study therefore believe that these data support the hypothesis that interacting and talking with one’s baby, particularly during the 18 to 24 month developmental period, promotes cognitive and language development.
“With these findings, we highlight the importance of implementing intervention programs quickly [in the baby’s life] to help parents create a home-based language learning environment,” the researchers wrote. conclusion to their study, published on the website of the American Academy of Pediatrics last week.
