It's important to note that there really isn't any scientific reason to separate hyperlexia into three categories. Hyperlexia is VERY poorly understood; there's an extreme paucity of hyperlexia research out there. The categories are just based on the observations of one researcher- he basically said, "yeah, I've noticed three patterns of experience among hyperlexia cases; here are the three ways it usually presents." His categories may or may not actually mean anything.
If you really look at the categories, it's kind of like he's saying, "Either we'll have soup for lunch, or we we'll have something else, or we won't eat at all." Well,
that's obvious! Know what I mean? He says that hyperlexic children are either autistic, or not autistic, or start off seeming autistic and then seem not autistic. That's not an insight.
Separating hyperlexia into categories doesn't really explain anything; it just states the obvious. And in any case, he's not basing the separation on anything more concrete than the reports of parents whose hyperlexic kids either do or don't end up coping well with the NT world. "I think my kid doesn't really struggle" means type I; "I think my kid is going to be independent and happy despite the initial struggles" means type III and "I think my kid is going to continue to struggle" means type II. And given that I'm an example of someone who's halfway between types II and III, it seems likely that hyperlexia is actually a spectrum, like any other autistic disorder.
And I think that if there were more interest in hyperlexia among researchers, these points would have been brought up by them already, and Treffert's "categories" would have been debunked by now.
That being said, the categories are useful in the same way that the words
small,
medium and
large are useful. They're meaningless on their own but handy when you're comparing things directly.
