Reading Literature on Screen: A Price for Convenience?: I was waiting for someone to do a study like this. The results confirm what I suspected, as I personally tend to rush more when reading something electronically.
A team of researchers led by Anne Mangen at the University of Stavanger in Norway and Jean-Luc Velay at Aix-Marseille Université in France divided 50 graduate students – with equivalent reading habits and experience with tablets – into two groups and had them read the same short story by Elizabeth George (in French translation). One group read the story in paperback, the other on an Amazon Kindle DX. All the while, researchers measured the students’ reading time and their “emotional response” – using a standard psychology scale – to the text. Afterward, they were tested extensively on different aspects of the story.
