Singaporean parents famously spare no expense when it comes to ensuring their children’s educational success, with estimates that up to 90 per cent of youngsters take tuition classes from early ages. But one of the most important investments parents can make to improve children’s learning outcomes is free. It turns out to be much more critical than enrichment programmes: It is talking to them.

This may sound like common sense and part of every family’s daily routine but a growing body of evidence shows that a massive word gap exists between children from disadvantaged families compared with their middle-class counterparts. Researchers in the United States note that by the time a poor child is three years old, she will have heard 30 million fewer words than a wealthier peer.

This is because of the patterns of interactions between parents and children in different kind of households. It turns out that, on average, less well-off parents speak less to their children, especially before children have developed language abilities, and the kind of speech tends to be more directive: “Stop that” or “Pick up your toys”.

Children are less likely to develop expansive vocabularies with directed speech because it requires little in the way of response and does not elicit conversation.
