I'd say something like internal monologue, for thinking anyway (this may be internally sounded, I know that I think word-thoughts in my own voice, but I regularly think much faster than I could possibly speak, until I realise that fact, when the voice becomes slow and I start repeating myself, and then get annoyed at my brain for being so distracting).
For calculating or anything vaguely mathematical I use abstractly spatial/visual sorts of thoughts -- abstract meaning I don't have sufficient awareness of the architecture of my brain to tell you accurately what I even mean. Generally I'm not very visual, but I would say I use a spatial sort of visual awareness quite often in thought. If this makes sense.
Does this imply something about the sorts of tasks I could do that were most useful? I'm intrigued by the reasons you have for requesting the data you did. :)
I requested that data because for some reason, in my own experience, I've noticed the tendency you mentioned in your previous post as being strongest when I'm trying to avoid the internal monologue way of thinking.
If I try to avoid using words in my thought process, I often find myself walking around empty-headed for some reason. It's as if it's a lot harder to start a non-verbal thought, or something. I don't know.
When walking around with a lot of thinking time on my hands, I've found a lot of success keeping myself occupied by simply saying words to myse...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
