Computer algorithm links facial masculinity to autism

This is certainly an interesting study, and I can’t see any obvious problem with the way it was done, but as with any study of autism, I believe questions about the validity of the diagnosis of autism must raise questions about the validity of any study of people (adults or children) who have been given that diagnosis.

Is autism a coherent, consistent, clearly-defined, clearly-delineated, natural category that explains purported cases better than alternative forms of diagnosis such as medical, genetic or sensory diagnostic categories? I doubt it. Let’s be clear; autism is nothing more than a multi-faceted description of behaviours, none of them unique to autism, and some quite common among people who have intellectual or sensory disability. There’s no biology, medicine or psychophysics in the core definitions of autism. I know of no validated, objective test designed to measure any of the sensory aspects of autism. Sure thing, autism is associated with countless congenital and genetic disorders, but the scientific validity of those categories doesn’t rub-off onto autism as a scientific category.

I’m a skeptic about the category of autism and I also have questions about diagnostic processes relating to autism and related disorders. We know that children who are purely and solely cases of prosopagnosia can be misdiagnosed with autism, and the literature on gifted and talented children includes many claims that the same can happen to G&T kids. I suspect that intelligence levels are a confounding factor in many studies that are supposed to explore autism or a broader autism phenotype, and I question whether the trend of identifying children as autistic when in the past they might have been identified as intellectually disabled was the great step forward that it is supposed to have been. There’s also the fact that the “testosterone theory of autism” has been around for many years now and has been widely popularized. It is certainly possible that parents and clinicians have been influenced to expect to see “autistic” behaviour in children who are perceived as more masculine than their peers, due to facial appearance or other traits. This conceivably could have a flow-on effect of increasing the chances that a boy or girl with masculine features might be identified as autistic, and this could be behind the effect found in this study.

These kinds of doubts are why in this blog I have never explored autism in terms of facial phenotypes or in terms of face perception deficits in any depth or with much interest. It’s not that I don’t see a problem or problems in these cases. I do, but I believe it is probable that one day in the distant future scientists will look back on the history of the sciences of the mind and wonder why we spent so much time and money researching autism, a concept that was a long, dark, gold-paved dead-end in the journey of scientific progress, while disability remained a constant issue.

Subtle FAS face from low levels of alcohol detected using computer technology

No safe level in my opinion!

Could super-recognizers see these subtle manifestations?

Ever noticed how the faces of couples often look a lot alike?

I notice it all the time, and perhaps this has something to do with being a super-recognizer. It seems to be especially common among couples that include a murderer or a politician. You should consider assortative mating or narcissism before you assume incest.

For important people only

I’ve just discovered the details of this “by invitation only” workshop that was scheduled for February past. I’m guessing the subject of the event was the Perth face-space project, which I have written about previously, but the description of the event seems deliberately vague.

Another computer algorithm created to perform a face perception task that any person can do without even thinking

Wenz, John This Algorithm Guesses Your Biological Age Just by Scanning Your Face. Popular Mechanics. April 1st 2015.

“For example, if a person appears to be considerably older than they really are, a doctor might look for something to explain that, whether it’s a genetic disorder or a lifestyle issue.”

I do not doubt the link between appearance of facial aging and genetic syndromes or drug addiction as I personally know of some real-life examples of both, and I don’t doubt that a good doctor should look for this in facial appearance and make appropriate investigations, but I do question why any doctor with normal eyesight and face perception would need a computer to do this, and I also question whether under the current “5 minute medicine” model of general practice in Australia, most doctors would have the time or the inclination to enquire about apparent accelerated physical aging in a patient.

I know of quite a long list of things that might accelerate the appearance of aging in the face, including at least one genetic disorder (I know of one family but do not know exactly which disorder), a drug addict lifestyle, smoking (which apparently destroys some vitamin and thus exposes cells to extra stress), and poorly controlled diabetes. There are probably many more things that can have this effect. Ask your doctor.

 

Interesting

This story about “information artist” Heather Dewey-Hagborg  creating art (face) portraits made based on genetic information from strangers is not new, but it is new to me and I think interesting

Poor Kenny

If you have ever doubted that simply looking at faces can be used to identify genetic disorders, consider case of Kenny the (very inbred) white tiger. Even though he is an entirely different species than us, we can tell just by looking at his face that something is seriously amiss. http://www.iflscience.com/plants-and-animals/kenny-white-tiger-reveals-price-inbreeding

Beats me why people are designing a computer program to do stuff that a super-recognizer could do standing on their head

Why, why, why do people assume that we need computers to do clever and sophisticated things in face recognition and face perception? Our brains have evolved over millions of years to do this stuff, and some people are even better at this stuff than the amazing feats of visual perception that the average Joe can do with barely a thought or effort.

If Abraham Lincoln had Marfan syndrome, identifiable through his facial appearance, then I guess that means that the Australian politician who was identified as a Lincoln double on the TV show Insiders must have it too.

If I were two-faced, would I be wearing this one? Abraham Lincoln

How many other politicians can you think of who could recycle that witty remark?

Jokes aside, its worth taking a look at the larger image of the group of faces in the magazine article, because they change in ways that I find quite fascinating and familiar. Which one do you think looks the most like Alfred E. Neuman? I think the right-edge lower row.
