In a recent study, Kindle readers were found to score lower in reading comprehension than people who read the same text in print.
The study, presented in Italy at a conference last month and set to be published as a paper, gave 50 readers the same short story by Elizabeth George to read. Half read the 28-page story on a Kindle, and half in a paperback, with readers then tested on aspects of the story including objects, characters and settings.
Apparently the largest difference came in how readers were able to reconstruct the chronology of a story. Obviously this show a biased for old-school linear story telling. Who cares whether Hamlet killed Polonius before or after Laertes kills Hamlet?
