I've seen this in studies before, and it is taught in the class "Learning How to Learn". Ever since I took this class, I have kept extensive hand written notes that I then turn into Cloze Anki cards. This takes forever, though. Handwriting is very slow.
To resolve this, I am currently taking time off from new classes to learn Gregg Shorthand. Soon, I'll be able to handwrite faster than I can type, and will get the same brain engagement that I know arises from handwriting. It is my hope that I can eventually write at the rate that I think, which is a major boon to the creative process of writing and storytelling.
