I know I am in the minority out there but when I do math, calculus, diff eq, whatever, the answer just comes to me. There's no internal dialogue, the answer just, for the lack of a better phrase, rises from the deep and is known to me.
When I am in an discussion I will look up and off the my left when I am thinking, but no words are happening in my "inner dialogue", it's just nothing and then I start speaking whatever I paused for.
Similar things happen to me while I am programming at work, I stare at the problem and the answer just comes.
