Why I’m a sucker for pen and paper
One aspect the article doesn't mention is spatiality, and how that aids memorizing.As you might know one very common technique used by memorizing masters is to place things you want to remember in some imagined 3D world.This effect is also something I've experienced strongly myself when listening to audiobooks while running. I figured I can actually remember the exact place along my running route in a nearby forest that I was listening to a particular passage in the book - and vice versa - going back in memory to a particular location immediately makes me start hearing memories from the book passages I listened to in that location!I think this aspect is at play a lot with handwriting as well. You are always writing in tangible places inside a notebook, while when typing things on the computer there is less of an immediate spatial location of each note. In any case that location will both be mostly the same for all notes (you sitting at the computer), and regarding any virtual spatiality of you computer desktop system, that will have a less tangible connection with your senses, (although any sense of spatiality surely can help a bit).
