I can however read code without verbalising, and with sheet music I can sort of directly execute the notes with thinking explicitly about the notes I'm seeing.
I can imagine some people can read prose in a similar manner, and I'd love to know how.
I've tried to sort of 'relax' my brain while reading, but then it seems nothing has actually registered!
Those that verbalise couldn't simultaneously do another verbal task, while the visualisers couldn't do another visual task, suggesting that separate parts of the brain were involved, and occupied by counting.
Now that I knew visual counting was an option (I was a verbaliser) I trained myself to do it. Unfortunately I'm yet to find an situation were the ability to choose between visual and verbal counting has been useful.
