Don't believe what you read (only once): comprehension is supported by regressions during reading.

Abstract in brief

• The study challenges the idea that eliminating eye movements like regressions can improve speed reading, showing that regressions are important for understanding text.
• Using a novel method where words were masked once the reader's eyes moved past, the experiment simulated rapid reading conditions akin to RSVP, effectively stopping regressions.
• Results indicated that preventing regressions negatively impacted comprehension, suggesting that natural eye movements are essential for better understanding, thus raising doubts about speed-reading apps that aim to eliminate these movements.]
