MICHELLE Dawson can’t handle crowded bus journeys, and she struggles to order a cup of coffee in a restaurant because contact with strangers makes her feel panicky. Yet over the past few years, Dawson has been making a name for herself as a researcher at the Rivière-des-Prairies hospital, part of the University of Montreal in Canada.

Dawson’s field of research is the cognitive abilities of people with autism – people such as herself. She is one of a cadre of scientists who say that current definitions of this condition rely on findings that are outdated, if not downright misleading, and that the nature of autism has been fundamentally misunderstood for the past 70 years.

Medical textbooks tell us that autism is a developmental disability diagnosed by a classic “triad of impairments”: in communication, imagination and social interaction. While the condition varies in severity, about three-quarters of people with autism are classed, in the official language of psychiatrists, as mentally retarded.

Now, research by Dawson and others has carried this concept a step further. They say that auties, as some people with autism call themselves, don’t merely think differently: in certain ways they think better. Call it the autie advantage.

How can a group of people who are generally seen as disabled actually have cognitive advantages? For a start, research is challenging the original studies that apparently demonstrated the low IQ of people with autism. Other studies are revealing …
