I'd be kind of surprised if people who have internal monologues need an inner voice telling them "I'm so angry, I >feel like throwing something!" in order to recognize that they feel angry and have an urge to throw something. I >just recognize urges directly, including ones which are more subtle and don't need to be expressed externally, >without needing to mediate them through language.

In our case at least, you are correct that we don't need to vocalize impulses. Emotions and urges seem to run on a different, concurrent modality.

Do ideas and impulses both use the same modality for you?
