Multiple studies show that digital screen use may be causing a variety of troubling downstream effects on reading comprehension in older high school and college students. In Stavanger, Norway, psychologist Anne Mangen and her colleagues studied how high school students comprehend the same material in different mediums. Mangen’s group asked subjects questions about a short story whose plot had universal student appeal; half of the students read the story on a tablet, the other half in paperback. Results indicated that students who read on print were superior in their comprehension to screen-reading peers, particularly in their ability to sequence detail and reconstruct the plot in chronological order.
Ziming Liu from San Jose State University has conducted a series of studies which indicate that the ‘new norm’ in reading is skimming, involving word-spotting and browsing through the text. Many readers now use a pattern when reading in which they sample the first line and then word- spot through the rest of the text. When the reading brain skims like this, it reduces time allocated to deep reading processes. In other words, we don’t have time to grasp complexity, to understand another’s feelings, to perceive beauty, and to create thoughts of the reader’s own.
