The importance of talking to babies
THE more parents talk to their children, the faster those children’s vocabularies grow and the better their intelligence develops… At three, children born into professional families had heard 30m more words than those from a poorer background…sending children to “pre-school” (nurseries or kindergartens) at the age of four-a favoured step among policymakers-comes too late to compensate for educational shortcomings at home… disparity appears well before a child is three. Even at the tender age of 18 months, when most toddlers speak only a dozen words, those from disadvantaged families are several months behind other, more favoured children… By the time children are two, there is a six-month disparity in the language-processing skills and vocabulary of the two groups. It is easy to see how this might happen. Toddlers learn new words from their context, so the faster a child understands the words he already knows, the easier it is for him to attend to those he does not. It is also now clear from Dr Fernald’s work that words spoken directly to a child, rather than those simply heard in the home, are what builds vocabulary. Plonking children in front of the television does not have the same effect. Neither does letting them sit at the feet of academic parents while the grown-ups converse about Plato.
