Asperger and Hyperlexia

Post Reply New Topic

I would like to know, on your opinions or a specialist's one, an opinion about these facts. Is an aspie necessarily one hyperlexical? In my example, I started to talk too late, around 3 years and a half old, and i learnt to read by myself at this age too. I'm asking this because I found some examples like mine among many people with AS.

Hyperlexia is not necessarily a feature of AS, but from what I've read it is common with us.
I first talked at almost 1 year old, then stopped for a while (after having tonsilitis) and began again at 14 months. I began learning my letters at 18 months, and was reading quite fluently before I was 3.
If you weren't talking until you were 3 1/2, you can't be AS as the diagnostic criteria disallows a significant speech delay. You could have autism or PDD-NOS, though.

Hyperlexia is so much more common among those on the autism spectrum that it is starting to be thought of as primarily an autistic co-morbidity (or superpower, depending on which researcher you're reading). I don't know a very large number of aspies or HFAs, but half of those that I do know taught themselves to read before kindergarten, with no help from parents or preschool. There is only one instance mentioned in the literature of a non-autistic hyperlexic, who seemed so out of the ordinary that they did a case study just to document that a non-autistic hyperlexic could exist.

But many aspies are not hyperlexic, so the two aren't synonymous.

i started teaching myself spanish with dictionaries when i was 10.

and still, my strongest lingual forte is reading.

I suspect I was hypelexic. Although I didn't learn to read before starting school, I did enjoy books a lot. I was reading at fifth grade level in first grade, in English, despite the fact that English was not my first language.
