I’ve long been sort of interested in the ongoing research that shows the importance of building vocabulary in children. This is famously summarized as the “30 million word gap,” thanks to findings that high-income children have heard 30 million more words than low-income children by age 3. But apparently new research is modifying these findings somewhat. It turns out that quality may be more important than quantity:
A study presented on Thursday at a White House conference on “bridging the word gap” found that among 2-year-olds from low-income families, quality interactions involving words — the use of shared symbols (“Look, a dog!”); rituals (“Want a bottle after your bath?”); and conversational fluency (“Yes, that is a bus!”) — were a far better predictor of language skills at age 3 than any other factor, including the quantity of words a child heard.
….In a related finding, published in April, researchers who observed 11- and 14-month-old children in their homes found that the prevalence of one-on-one interactions and frequent use of parentese — the slow, high-pitched voice commonly used for talking to babies — were reliable predictors of language ability at age 2. The total number of words had no correlation with future ability.
In practice, talking more usually leads to talking better, so there’s probably a little less here than meets the eye. Still, it’s interesting stuff. Regardless of parental education level, it turns out that simply interacting with your newborn more frequently and more conversationally makes a big difference. So forget the baby Mozart, all you new parents. Instead, just chatter away with your kids. It’s cheaper and it works better.
