Researchers led by Dr Matthew Schneps observed around 100 students reading on both papers and e-readers.
They found that some students who struggled sight-word reading and limited visual attention spans managed to read faster and had better comprehension when reading on e-readers. The study has been published in the journal PLOS One.
"The key factor that's important in the effect being helpful is that there's a few words per line. We think that could apply on paper, the blackboard or on any device. If people are struggling to read they may want to try to simply blow the text up in their small computer-like device to see if having fewer words helps", Dr Schneps said.
