I certainly don't think in language. Easy evidence: I know the idea of what I want to say, but I totally forget the word. Language is just something I have to compile to once the idea is fully formed.

I understand that lots of people actually do think in language, but you shouldn't assume that everyone follows the same mental process.

Just because you can't think of a particular word at a given moment, do not assume that you are thereby not thinking in the language. Experiments show that it is far, far more subtle than you might imagine, and that your language affects how you think in ways you might not expect.

I've participated in experiments[0] that clearly showed that my perceptions of what was happening in my head with regards language were simply not true. Introspection is extremely subjective, and very poor at getting at reality.
