Children who do most of their reading on screen enjoy the stories less and have a poorer reading ability than those who use printed materials, according to a recent survey by the National Literary Trust.

With the number of children using e-books, tablets and computers having doubled in the last two years, and rising, the NLT is calling for a healthier balance in reading using both books and technology.

Its findings from a survey of almost 35,000 children aged 8-16 are worrying but also reveal another interesting statistic: girls are more likely to read in print than boys, and are also more likely to read from a range of on-screen devices.
