Since then, much of the focus of early childhood language development has been on getting children to hear a greater number of words. However, some believe that the word gap is an overly simplistic approach to language development, and in this study, Dr Rachel Romeo, a postdoctoral research fellow at Boston Children’s Hospital and lead author of the Harvard study, set out to examine more about the quality of speech children are exposed to as opposed to just quantity.
“Our findings show that the information highways between the language regions of the brain were stronger in children who took turns talking with their parents, and the greater connectivity held true independent of socioeconomic status,” said Romeo explains in an interview with ABC news.
The researchers recorded the children and their parents for two days to capture the number of different words children heard, the number of words they spoke, and the number of turns they took in back-and-forth conversations with their caregivers. The team then used an MRI to take images of the children’s brains, and performed common office tests to measure the children’s verbal and cognitive abilities.
What they found? The children who took more turns in back-and-forth conversation with their parents had stronger connections between the brain regions responsible for comprehension and production of speech, and also scored higher on verbal skills tests, the study found.Explore more on these topics:
