Recorded lectures have become a routine part of course instruction during the COVID-19 pandemic, and college students often try to pack more learning into a shorter span by watching these recordings at double their normal speed or even faster. But does comprehension suffer as a result?
Surprisingly, no—up to a point. A new UCLA study shows that students retain information quite well when watching lectures at up to twice their actual speed. But once they exceed that limit, things begin to get a little blurry, said Alan Castel, the study's senior author and a UCLA professor of psychology.
