The methods you describe are not methods for study, but methods for programming.
A student doing research actually gathers information from many different sources, some, hopefully, with differing viewpoints on the subject. Blah, blah, blah...
What I did learn, however, is how to sit still for long periods of time, which helped in learning to meditate. I learned to read at a much earlier age than most due to the WT&A! studies. And I think I (and most of us here) have a more expansive vocabulary than your average person due to the "studies".
