The interesting thing about captions is that they are turned on not only by people with hearing disabilities, but also by users who don’t have any hearing impairment. Many people who aren’t, for example, native English speakers, will enable captions in order to understand the content better. This can also help to learn the target language more easily. On the other hand, even native speakers can prefer watching transcribed videos because it helps them memorize what has just been said. For example, many students actually learn better while watching videos (like lectures) with the captions on, because visual learning enhances the memorization of the subject.
