I have no idea how I think. It's probably because I think in a combination of all the above - most people do, I guess. There's a lot of love these days for visual thinkers because the arts and creativity is so prized. Musicians are prized, too, so in that way, the mathematical/musical thinkers are idealized.
I know that I'm a holistic thinker, while most people think a lot more "straighter" than I do.
I never understood the forms that ask how you learn best - through reading, hearing, watching, doing, etc. I'm not really sure how I learn best. I know I'm not good at completing things on time, though.
