“Certainly, as we turn to online reading, the physiology of the reading process itself shifts; we don’t read the same way online as we do on paper. Anne Mangen, a professor at the National Centre for Reading Education and Research at the University of Stavanger, in Norway, points out that reading is always an interaction between a person and a technology, be it a computer or an e-reader or even a bound book. Reading “involves factors not usually acknowledged,” she told me. “The ergonomics, the haptics of the device itself. The tangibility of paper versus the intangibility of something digital.” The contrast of pixels, the layout of the words, the concept of scrolling versus turning a page, the physicality of a book versus the ephemerality of a screen, the ability to hyperlink and move from source to source within seconds online—all these variables translate into a different reading experience.”
