I think I'm visual but I'm also very sequential. I did the outline thing for studying, too, EandCMom. I think the photographic memory thing is a visual trait--we "see" the page in our heads.
Actually, I didn't realize how visual I was until I started writing my novel. As I was trying to describe a character that I was creating or a setting, I realized that I would see a "picture" of the person or place in my head, and then the hard work for me would be to try to find the right words to describe that vision.
A trick: think about what you were doing yesterday at this time.
Did you see yourself doing it, or did you think of the words "fixing dinner" or "typing on the computer"?
If you saw the picture, you probably tend to be more visual. If you thought of the words, you're probably more something else.
