Douglas Quenqua had an interesting piece in the Oct. 16 NY Times that I just got around to (thanks, Eric!), the burden of which is well summarized in the title: “Quality of Words, Not Quantity, Is Crucial to Language Skills, Study Finds”:
Now, a growing body of research is challenging the notion that merely exposing poor children to more language is enough to overcome the deficits they face. The quality of the communication between children and their parents and caregivers, the researchers say, is of much greater importance than the number of words a child hears.
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.
“It’s not just about shoving words in,” said Kathryn Hirsh-Pasek, a professor of psychology at Temple University and lead author of the study. “It’s about having these fluid conversations around shared rituals and objects, like pretending to have morning coffee together or using the banana as a phone. That is the stuff from which language is made.”
There is, of course, more about this study and another one 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”) at the link.
