Scientific Brain Linked to Autism

squoozer writes "The BBC is reporting that a leading scientist in area of Developmental Psychopathology, Professor Simon Baron-Cohen, is indicating that there is good chance that there is a scientific basis to the observed phenomenon that children with highly analytical parents are more likely to be autistic. He believes the genes which make someone analytical may also impair their social and communication skills. A weakness in these areas is the key characteristic of autism."

Re:Evolution

[murderlegendre]

This is more accurately a social restraint on nerds breeding. I've never seen any information to suggest that there is a lower rate of fertility among autistic / aspergers individuals, or even common nerds.

Over the large span of human evolution, characteristics such as physical strength, size, agression and so forth had much more to do with the ability of an individual to procreate, as opposed to the ability to smooth-talk a member of the opposite sex.

Our modern social conventions are obviously much 'nicer', but as for the positive / negative consequences for our gene pool, only time will tell.

'Social skills'

[0123456]

I'm still trying to figure out what people mean by 'social skills' here. As far as I can see, it's basically lying and bullshitting, which surely can't be hard for any smart person to learn? I'm sure most of us are pretty successful at bullshitting our bosses, if nothing else.

I think what really upsets the average person is not that 'geeks' don't have 'social skills', but that they just can't be bothered to bullshit with someone who has little to nothing in common with them. Why bother? What's the point in spending an evening talking about football scores when you could be doing something constructive and interesting instead? I don't get it.

It is far more than lying and bullshitting. In a social situation, most people can talk naturally. They simply say what comes to mind. For someone with autism, they have little to no intuation. They literally have no concept of what to say or do. If it is severe enough, the only way they can perform in social situations is to observe how others act and react and mimic them when they are in similar situations. This is much more analytical than intuitive to do. If they can't choose a reaction they can't create one on the fly and will just freeze and say very little ("ah, i see") or nothing at all.

They also generally have a difficult time understanding and picking up on more subtle forms of communication. They only hear the words. They don't hear the emotion or inflection or notice the facial expressions, and they have a difficult time reading (or listening as it were) between the lines. Furthermore, they have a difficult time extrapolating the thoughts and feelings of another person. They can't "put themselves in the other person's shoes." Basically, if something isn't said, it doesn't exist to them. That is a crippling disadvantage in social situations.

[Ignignot]

While the article does say that people with highly analytical brains tend to have more Autistic children, it does not say that people with poor social skills tend to have highly analytical brains. I think it is a common fallacy around here that not knowing how to interact with other people well is some kind of badge proving how smart they are. Or to put it the slashdot way, even if you have a really fast Athlon 64 system, if you are connecting to the world with a dialup you aren't going to be able to play an online FPS well.

Re:Evolution

[E 99]

Again the "you can't have it all" fallacy? Even if it's impossible with today's genes to be both brilliant, handsome and socially capable (which I doubt), it's not at all impossible that, over time, genes will mutate and spread so that one can be all of these.

It's not a fallacy, it's an inevitability. The things you mention, intelligence, good looks, and social skills, can only be meaningfully measured in comparison with the societal norms. To quantify, I would throw out that the terms brilliant, handsome and socially capable, are applied to say, those in the 98th or 99th percentile of those categories. Regardless of how humanity evolves in the future, the likelihood of the same person being in the high percentile in all three is necessarilly extremely low (myself being the obvious exception :-)). Maybe some future society is full of nothing but beautiful geniuses, relative to our standards. Or maybe we're that society relative to some pre-historic version of ourselves. It doesn't really matter, as people are judged by the standards of their own societies, which will always have a high end and a low end in any given measure.

Wrong Line of Research

[randall_burns]

Here's the basic problem:
at this point, there is no reliable _physical_ test for autism.

All diagnosis of autism has to be done using behavioral analysis--and the criteria very greatly accross legal jurisdictions(i.e. what is "autistic" in california may not be in Wyoming).

The genetic line of reasoning is also rather questionable. There are clearly genetic risk factors(about 90% of autistic are type A blood type and male for example)--however the percentage of Type A kids that are autistic varies a _lot_ in various areas. Even among identical twins, raised together, about 5% of those autistics have a twin that isn't that may go down further if you change the line to explude milder lines of autism)--and there are lines of research that claim there are risk factors that aren't genetic that all twins would share.

What I think we need most urgently here:
a good, biological test that can sort out autistic from non-autistic kids reliably. The closest thing I've seen to this is the work of V.K. Singh at Utah State and Hugh Fudenberg(formerly of UCSF).

I expect we are seeing several different viral and environmental causes of autism spectrum disorders. There may genetic susceptability--just like populations differ in how much they are impacted by various infectious diseases. However claiming that stuff like assortive mating and genetics is causing autism just isn't good scientific method.
