I read each and every word and sub-vocalize each one. Though I often forget to reread stuff I write and type past words, I always see the extra the or you or whatnot. But I think my approach is how I learned to fix and cope with the floating text vision issues; if I read with only my rght eye it floats all over the text in little loopy loops, and if I at the same time try to read without saying words it takes many times longer and word recognition is much harder with words longer than around seven letters. Now I'm wondering about coaching ds with sub-vocalizing or hope he discovers his own way.
