Short-form videos may make newly learned information harder to remember, but the experiment tested fragmented travel clips rather than every brief lesson or every person’s scrolling habit

The design tested several disconnected travel clips against one continuous travel video, which is a narrower and more useful claim. What the researchers actually testedIn the first two experiments reported in Communications Psychology, researchers randomly assigned university students to watch either a continuous 10-minute travel video or a 10-minute sequence made from five to seven unrelated travel clips. Here, poorer recall for fragmented travel videos does not mean that a person’s overall memory has been damaged. The researchers themselves warn against reading their results as evidence that every instructional short video is inferior. In these experiments with university students, watching several disconnected short travel videos produced poorer recall than watching one continuous video of the same total duration.
