Sometimes you have to go outside your field of study to find the right people.

The thing is, autism is all different, you know, variables. And you start out with a certain amount of, you know, the point where the differences in the brain are going to just be a personality variant and, like, for very mild Asperger's. But you get into more severe kinds of autism where there's obvious speech delay, obvious abnormal behavior in a two and three-year-old child, you know, the initial neurology is different from case to case. But all children with autism are going to do better if they get really good educational intervention.

If you have a 2 or 3 year old who is not talking, you must start an early intervention program. The worst thing you can do with an autistic 3 year old is to do nothing.

I think the mild Aspergers have always been there. You see, Asperger's diagnosis did not become common in the U.S. until the early '90s. And an Aspergers has more or less normal speech development and they've always been here, that hasn't changed. I can think back to when I was in high school, this is 40 years ago, I could name kids in my high school class and college class that, today, would be diagnosed as Aspergers.

I like to figure things out and solve problems.

Some autistic people have savant skills. All autistic people do not have savant skills. Autism is a very variable disorder varying all the way from Einstein, emollient scientist, just a little bit of the trait, many scientist and engineers, down to somebody that's going to remain nonverbal.

Animals do have emotion. But fear tends to be one of the most primal emotions.
