Not much is known in this field as it's a very tough concept to study, due to the nature of reading someone else's work for study adding another level of Cuil abstraction detracting from the objectivity of your study.
This leads to an even bigger question, is what you're learning what you're learning or are you merely perceiving it as what you're learning just by wanting to learn, and experiencing the action of doing so?
Not sure if srs?
