Speed-reading apps can impair reading comprehension by limiting ability to backtrack, point researchers.
Psychological scientist Elizabeth Schotter of the University of California, San Diego, lead author of the new study, said that their findings show that eye movements are a crucial part of the reading process.
AdvertisementSchotter and UC San Diego colleagues Keith Rayner and Randy Tran conducted a study examining the role that eye movements play in the reading process, which is rendered impossible by rapid serial visual presentation (RSVP), the method used to display text in speed-reading apps like Spritz.
Studies have shown that readers make regressions, moving their eyes back to re-read bits of text, about 10 to 15 per cent of the time; Schotter and colleagues tested the hypothesis that these regressions could be a fundamental component of reading comprehension.
The researchers recruited 40 college students to participate in the study. The students were instructed to read sentences (displayed on a computer screen) for comprehension. Sometimes the sentences were presented normally; other times, the sentences were presented such that a word was masked with Xs as soon as the participants moved their eyes away from it, making it impossible for them to get more information from the word were they to return to it.
The results showed that, during normal reading, comprehension levels were about the same whether the students did or did not make a regression. These results suggest that we only make regressions when we fail to understand something, and we can fill in the gap by going back to look again.
But, when the researchers compared data from the normal sentences and the masked sentences, they found that the students showed impaired comprehension for the masked sentences, presumably because they weren't able to re-read when it would have been helpful.
The research has been published in Psychological Science, a journal of the Association for Psychological Science.
