Conceptual thinking apparently. I guess most people think with words. I think with concepts, visuals, emotions, and other sensory inputs. It means I can understand things much more quickly by associating concepts. And combine those things quickly to make something new. I rarely need to memorize all the details of something if I can extrapolate those things from the conceptual models in my head as needed.
But it does mean that every word that I use needs to be translated from a concept first. Translation takes time and energy, just like it does for the majority of people who speak multiple languages with widely varying grammatical patterns.
