I don't nesscarily associate autism with being ret*d. Those are two different terms. Autism is when someone has social skill delays and sensory issues; it ranges from mild to severe. Mental retardation is when a person has an IQ of <70. So why do people think all autistic people are mentally ret*d?
Actually, mental retardation is when a person has an IQ score of <70 AND has difficulties in daily life. There are quite a few people who are bad at taking IQ tests but who are not mentally ret*d because they do just fine and never need help.
Alex--We still use the term "mentally ret*d" here in the US because that is what is in the DSM. Around here, calling someone "ret*d" or "a ret*d" as an insult is still considered offensive; but "mental retardation" or "mentally ret*d" is not.
Anyway, people often think autistics are all MR because they don't know a lot about autism. A lot of autistics are MR, but many aren't; and those who are don't have the same characteristics as MR alone.
Autism does have a close association with mental retardation. In fact, twenty years ago, many people who are now diagnosed autistic would have been diagnosed mentally retarded--we are "stealing" cases from the MR category, and this is probably part of the increase in autism diagnosis.
However, I think it's very important for doctors and parents to remember that when an autistic person fits the definition of "mental retardation", this means different things than if he were not autistic. Autistic people have different development patterns; and while it's a fair guess to say that someone with simple MR caused by being on the low end of the Bell curve (the cultural/familial type) will be slower to learn to read or do math, you can't make that assumption about someone with the autism/MR combination. Social skills are often a relative strength for people with MR... but for those with the autistic/MR combination, they will be a weakness. In fact, you really can't make very many assumptions at all when autism is concerned.
I think that IQ, as a measurement for autistic people, is not particularly useful. IQ compares you to the norm--to the typically developing population--and assumes that if you score lower or higher, you are part of that population but just going at a slower or faster rate. This is not true of autism; development for autistics often occurs in jumps and plateaus, progresses at different rates in different areas, and sometimes even goes backwards.
So autism/MR is a different thing from MR alone... It's not the same thing as simply adding the traits of one to the traits of the other.
