That seems like a lot of work to demonstrate the obvious. 😆 I mean just off the top of my head I can see dozens of different motion and muscles that are activated, you have to actually picture the shape and flow of the letter and the word, predict the spacing of the words, etc - there’s numerous things that typing is explicitly supposed to be a shortcut for, thus those things wouldn’t be activated. I guess I’m not trying to hate, but it seems a little “duh” to me, lol. And when it comes to remembering what you wrote vs typed, it also makes sense that you would retain it a little better when written specifically because tying it to a more intricate and explicit motion actually sets things into the mind more concretely. If every letter and word is different, there’s a lot of pathways being fired. When typing everything is just the same tap motion.
