[IlliOnato]

For me the essential part of comprehending new information is my own thinking on what I'm getting. When reading a book, I stop frequently to think, it's quite natural for me. Often go back a few paragraphs or pages, re-read them with the new understanding, think again, go ahead...

All of this is possible with video and audio in principle, but much less natural and much less convenient; also video somehow "hypnotize" me and I don't feel the urge to think about what I see and hear at the moment; perhaps only afterwards if at all. I have a feeling "oh I get it", but not much remains afterwards.

So I absolutely prefer text to audio or video when learning.
