Not sure if nonverbal is the right word for it, but those that who think not as if they’re speaking in their mind, through some other ways like imagery, feelings, or however.
Often the conscience is described as a little voice in one’s mind saying what’s right/wrong to do, but for those that who think differently, how’s that experienced? Good/bad imagery or feelings instead?
It would be a mix for me. (I mean deaf and mute people still have a thought process even if they have never heard the language as a voice in their head–I assume) Sometimes it can be an internal monologue, but other times, especially doing engineering tasks, there are no words it is just visualization of steps or process or concepts. i also have noticed that if I’m thinking in language I can type it very fast and it flows, if I try to talk to people the act of verbalizing interupts pulling the words forward in thoughts. And I have to pause to think of words or process for a sentence. The only way this doesn’t happen is for very rehearsed topics.
