New research suggests having the TV on may impair young children’s development by reducing the amount of conversation between infant and adult. So how bad is the box for young minds? A US team recorded more than 300 children aged between two months and four years on several days every month over two years. They found that when the TV was audible – either on in the background or being watched – the number of words spoken and sounds made by either adult or child reduced considerably. It is the latest study to imply that delays in language development may be the fault of TV, a medium blamed for a host of other modern ills, from bullying to obesity.
