The debate between paper books and e-readers has been vicious since the first Kindle came out in 2007. Most arguments have been about the sentimental versus the practical, between people who prefer how paper pages feel in their hands and people who argue for the practicality of e-readers. But now science has weighed in, and the studies are on the side of paper books.
Reading in print helps with comprehension.
A 2014 study found that readers of a short mystery story on a Kindle were significantly worse at remembering the order of events than those who read the same story in paperback. Lead researcher Anne Mangen of Norway's Stavanger University concluded that "the haptic and tactile feedback of a Kindle does not provide the same support for mental reconstruction of a story as a print pocket book does."
Our brains were not designed for reading, but have adapted and created new circuits to understand letters and texts. The brain reads by constructing a mental representation of the text based on the placement of the page in the book and the word on the page.
The tactile experience of a book aids this process, from the thickness of the pages in your hands as you progress through the story to the placement of a word on the page. Mangen hypothesizes that the difference for Kindle readers "might have something to do with the fact that the fixity of a text on paper, and this very gradual unfolding of paper as you progress through a story is some kind of sensory offload, supporting the visual sense of progress when you're reading."
