I taught myself to read at age 4, and I believe that I was hyperlexic as a child. I also believe that I am hyperlexic in Spanish, which I became fluent in by self-teaching myself advanced grammar. I also think in text (in addition to having an inner voice), as well as "see" text whenever I hear spoken words. I recently heard this is a type of synesthesia known as "ticker tape synesthesia." I have the "ticker tape" experience with Spanish, too, not just with English. And I have always struggled with math and visual-spatial tasks, which is because I have NVLD. The only math I'm good at is algebra.
