Yes, this is an aspect that I’m interested in too. I just read a book called Speed Reading with the Right Brain.
Its premise is that if you read with your senses then you experience and comprehend and remember more. So if you read the words “the red telephone box” with only the logical left brain you don’t get the same experience visualising it with taste, touch, smell, colour, etc, and intentionally bringing up some kind of concept about it like its association with Dr Who…
So the idea of actively visualising recruits more parts of the brain, even when used in high speed reading.
I practice a technique called Eyebody which was created by a guy who was legally blind but learnt how to restore his vision. It includes visualising in the upper visual cortex at the upper back part of the head. That’s where the brain sees and experiences the world with much more depth and richness and sensory integration. It has greatly enhanced my experience of seeing and I’m beginning to apply it to mnemonics and reading too.
