Interesting thesis you did there.
Can you tell us why comprehensions when teading digital text are 10% less than when reading THE SAME content in printed form?
What factors cause this decrease in comprehension?
I believe it has to do with brain processing. For example, why is typing 30% less efficient than hand writing for comprehension? We are physical beings, and we respond more completely to physical stimulus. I doubt we’ll ever know why since the computer industry has done a phenomenal job of ensuring people can’t find out the answers.
I also believe that the touch, look, even smell of books improves comprehension. Reading is more sensory than we’re aware of.
“Why” wasn’t researched - it was hard enough to get straight data. I believe it relates to the difference between live and recorded music, meeting someone vs seeing a photograph. There are more physical senses involved with print even though we don’t realize it, and many more visual cues. Brains also process light differently from reflected light from a page. The educrats and computer industry are working hard to make sure nobody asks about this, and if they do, to snow it under.
