An interesting study described in Eureka notes:
A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the unique, complex, spatial and tactile information associated with writing by hand on physical paper is likely what leads to improved memory. "Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall," said ...a neuroscientist at the University of Tokyo and corresponding author of the research recently published in Frontiers in Behavioral Neuroscience. The research was completed with collaborators from the NTT Data Institute of Management Consulting. Contrary to the popular belief that digital tools increase efficiency, volunteers who used paper completed the note-taking task about 25% faster than those who used digital tablets or smartphones.
The hand, eye, brain interaction creates improved understanding. No school teaches penmanship in the West any longer. One need just look at a student trying to write and it makes the Neanderthal look more adroit. The student clutches the pencil or pen as if they have some butcher knife at the ready to "cancel" an adversary permanently.
Humans spent millennia developing hand, eye, brain coordination just to lose it in a few decades. We no longer write letters in our hand writing, sign checks, or take notes in class. Try and find a student using a note book. Yet they carry around tons of books filled with useless color pictures.
