The same face? The same young lady?

Face recognition, face identification, face matching, call it whatever you like, the question of whether some photographs are records of the same face (at different ages) is central to solving a long-argued and fascinating mystery about the famous author Lewis Carroll. My first impression, as a super-recognizer, is that the mystery photo is of the same young lady. As a super-recognizer I look at the whole face and feel whether it is the same person whose face I have already become familiar with. As a logical person who who understands that a proper investigation involves looking for any evidence that potentially could disprove a proposition, I would like to spend more time looking individually at all of the facial and body features in two photos to see if they match or have clear differences that cannot be explained by the effects of age or other possible alteration, just as the people do in this documentary.

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.


Make no mistake

Occupational Therapy and neuroscience are not the same thing, and I find it pretty annoying when the former is presented in a way that makes it look like some kind of science that I or anyone should take seriously. Don’t waste my time. For heaven’s sake, there’s enough nonsense, hype and shoddy work in neuroscience as it is.

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.
