Artistic talent and super-recognition?

I’ve had my nose in books, as I do, and I’ve read that some great artists had very “vivid” visual memory, which would presumably be a different thing to creativity. Names such as Toulouse-Lautrec and Michelangelo have been cited. So this made me wonder whether I have or once had a level of artistic talent to match my excellent visual memory for faces. I’m not a visual artist. I don’t do visual art as a hobby even. I do enjoy taking photos, but nothing technical or fancy. I do enjoy creating things. I enjoy working with colour. I love going to visual arts events, as you can see from my blog. But I don’t think anyone would identify me as an artist. As a child, I think perhaps people would have. Children are encouraged to express themselves in visual art, and I obliged, as did most kids, and I also enjoyed art enough to do it in my own time at home. I did art as a year 12 subject and enjoyed it but didn’t take it hugely seriously. Perhaps being myopic but never identified as such during my school years limited my ability to draw. Perhaps my ability or interest in art is attributable to my synaesthesia, independent of my face memory ability.

Unlike so many aspects of my childhood, I remember,  in striking detail and vividness, creating art as a young child.  I remember the colours and the names of colours in a large watercolour set given to me as a young child. I remember drawing the intricate wrinkles of my own hand with the other hand at home. I remember the colours of my pencils in grade 1, and the colours of the little dyed wooden shapes we were given to learn about numbers. I remember being laughed at in grade 1 when I showed the class a painting I did at home using perspective. I remember thinking at the time that my classmates were idiots. I remember the simple joy of looking at things, even tiny things or objects of no particular importance to most people. I remember being fascinated and entranced by the structures and colours of found objects such as bird feathers and sea shells. I remember discovering that beach sand is made up of grains that can have striking and vastly different colours: dark brown, bright orange, magenta, white, transparent like glass. As a young lady I got decent marks in art in year 12 and I think my art reflected an ability or a willingness to simply draw what I saw, rather than reproducing some abstract idea of what I thought a tree or a vase should look like. My art teacher said I had ability but failed to develop it, and I think that probably sums the story of my artistic talent.

Are you a super-recogniser? Are you also an artist? Are you a super who is utterly lacking in artistic ability? What do you think? What do you know?

Interesting letter from last year re acquired prosopagnosia and the uncanny valley

Editor’s pick: Excluded from the uncanny valley
From Bob Cockshott

New Scientist. Issue 3100. November 19th 2016. p.60.

https://www.newscientist.com/letter/mg23231002-500-1-editors-pick-excluded-from-the-uncanny-valley/

The experience described in the letter seems to suggest that there is more to face recognition than simple memory or faces, or could it be that there are aspects of the perception of faces in particular that make them especially memorable? Faces are easy to personify because they are usually found on people. Perhaps it is the ability to detect the person behind the face that has become amiss in the letter’s author following his stroke, and maybe this ability feeds into face memory? Such a relationship would explain the author’s inability to notice the uncanny valley, and it would also explain why a personifying synaesthete like myself is also a super-recognizer.

P.S.

I’ve had a read of the interesting article by Laura Spinney that this letter was a comment about, and I think the Perceptual Mismatch Theory of the Uncanny Valley Effect probably offers a more plausible explanation of my a prosopagnosic might be unable to detect the uncanny valley than the competing Category Uncertainty Theory. The article explained the two theories and evidence supporting them. To summarise, the CUT explains the UVE as the result of confusion about what type of thing one is looking at (for example robot or human?), while the PMT explains the UVE as resulting from unease or perceptual confusion when different features or parts of the thing or being viewed have dissimilar levels of human-like appearance (for example the face and skin look realistic but the eyes do not move like human eyes). I think the case of a prosopagnosic not detecting the UVE when people with normal face perception do is support for the PMT theory rather than the other because as far as I know, prosopagnosia does not involve inability to classify faces or bodies as human or non-human, while I believe there is evidence supporting the idea that prosopagnosia can be the result of not being able to perceptually integrate the features of the face as a whole that is recognizable as a unique or distinctive mix of many attributes and features. A non-prosopagnosic person should be able to perceive a face or body as a whole made up of parts, and notice if one or more elements has a level of humanity that does not match other parts, as in the PMT, while a prosopagnosic might not. Of course, research is needed to investigate my armchair speculations.

Surprising explanation for why face recognition matures unusually late in human development!

I didn’t expect to be reading this but I can recognize that this discovery seems to explain why face recognition is human cognitive ability that hits its peak surprisingly late in human development, and I’m now wondering how this fits into my theories about the relationship between my super-recognition and my synaesthesia, and that includes wondering how this discovery fits with my immune hypothesis of synaesthesia (which is all about pruning rather than proliferation), and of course I’m wondering how this fits in with what is known about super-recognizers. I guess I should just calm down and read the full text.

Prosopagnosia report on Sunday Night on Australian commercial TV this weekend

Preview at link below. Apparently a face perception researcher from Western Australia will be featured in the report, as well as Australian celebrity prosopagnosic, pop science book author and science popularizer Dr Karl Kruszelnicki. This sounds good, but at the same time, this is pretty-much tabloid TV so I have limited expectations for this report. The promo looks sensationalist and misleading, with the use of the inaccurate term “face blindness” rather than prosopagnosia, along with misleading illustration of the concept with blanked-out faces in the promo, making it look as though prosopagnosia is a perceptual problem rather than a visual memory problem. I think it should be called face memory deficit disorder or something similar. I’ll be watching with interest anyway.

I was glad to read in this substantial and interesting article that face identification was not the only evidence used to convict criminals. And the last couple of sentences in this piece are too true!

Memory is fallible, but then again, there’s super-recognizers

It appears that super-recognizers (people with very good face recognition ability) are mentioned in the new book The Memory Illusion by Dr Julia Shaw, but I cannot find a preview of that bit of text. I’d be interested in reading what Shaw wrote about supers, because I believe that we are very good evidence against the argument that this book, and some other pop psychology books have offered, that human memory is unreliable and open to interference. I’ve noticed that writing by researchers and authors who offer arguments against the reliability of human memory and also those who offer arguments against the idea of natural or inborn talent tend to ignore or gloss over the many things that science already knows about face recognition, face memory and super-recognizers.

I’m happy to admit that people who perform amazing feats of semantic memory such as remembering huge lists of random facts or meaningless digits using new or ancient memory techniques have trained their own memories with many hours of practice, but super-recognizers are very different to those people. We do not knowingly or deliberately train ourselves and we do not consciously use tricks or techniques. Maybe we self-train and invent strategies in an implicit manner, but it is also true that super-recognition does seem to run in families, so there seems to be an important genetic contribution to the elite ability or talent, just as there is clearly a genetic component to developmental prospagnosia (very poor face recognition ability).

Face memory researchers have been investigating the phenomenon of super-recognition since it was first described in 2009, and there seems to be ample evidence that supers have very long-lasting, adaptable, and reliable memory of the faces of other humans. We can remember faces across many decades and across changes in facial appearance by forces such as ageing. I believe I am very good at spotting facial family resemblance and facial phenotypes across gender and age. Super-recognizers can also display very accurate face recognition after being briefly shown images of only faces (no hair etc) of a large group of faces of same gender and similar age, some of them very degraded images. This accuracy requires being able to avoid false positives and false negatives. There’s no denying that supers are bloody good at faces. There’s also no denying that some other people are very poor at face memory, so authors of these pop psychology books that denigrate human memory are able to state with a vague air of truth that human memory for faces is fallible. But such a statement ignores what we know about supers, and this is why I have issues with the common practice of psychology researchers of roputinely discarding data from outliers in their studies. If any of that discarded data is from outlier study participants that did incredible well in tests of face recognition or memory, then those participants could be supers and their data tells an important story about human memory and human face recognition.

I think supers are interesting examples of a type of human memory that stands out from other types of human memory as reliable, long-lasting, easily or unconsciously enmcoded and accurate, so one should wonder, why is the face memory of supers so great? My bet is that this niche example of human memory has two characteristics that give it special power: it is disributed across a broad network of neurons throughout the brain (and this is why it might be found along-side synaesthesia), and it is also a type of visual memory, which I can only assume is a very ancient and well-evolved type of human memory that predates stuff like writing and language, that happens in areas of the brain that work amazingly and unconsciously because they evloved well before there ever were humans. I cannot imagine how genuine face memory could ever be interfered with by suggestion or manipulation, because the tricks that some memory researchers have used to fool around with the memories of study participants work on a conscious level communicated by verbal means. Genuine face memory is implicit and visual. It is safe from such nonsense.

But is it really Gina?

I’m well aware that weight loss, ageing and remodelled or drawn-on eyebrows can mess up our natural face recognition abilities, but even though, I’m not 100% convinced the lady in the photos is really the Australian mining magnate Gina Rinehart. I feel that the lady in the photo has quite a different personality than Rinehart, kinder but perhaps not as canny.

If this lady is the real Gina, I’m sure she’s had work done on her face, and in my opinion, her unique personality can no longer be seen in her face. I hate watching the fascinating faces of famous women all morph into that homogenous face of the older woman who has had her face done over.

Is the “voice artist” Andrew MacRae the same bloke as the “fake tradie”?

Same face, do you think? I don’t, and my opinion should count for something as I score in tests in the super-recognizer range. At first glance I thought the man shown in the vision of the political advertisement that Australia is currently heaping ridicule upon and the Andrew MacRae shown in a photo on Twitter who has been identified as the bloke in the ad were two different people, and after having a careful look at many different aspects of the appearance of the faces and ears and hairline, I’m even more sure that these are two different people, in appearance.

I’d say the bloke in the silly ad looks older than the man in the photo at the Twitter account of Andrew MacRae, but appearance is probably irrelevant anyway, because I think the ad has been dubbed. The voice is of a man trying to sound like a working-class person from England. The credits at the end of the ad read “Spoken by A. MacRae” so this A. MacRae need not look anything like the dude pictured in the ad, who could well be an actor. It is anyone’s guess what this A. MacRae looks like. The voice artist denies it is him. Maybe this is true. There must be heaps of men with the name “A. MacRae” in Australia.

Australian super-recognizer suffers from social embarrassment after misidentifying stranger as an acquaintance

The amazing thing is that I had earlier seen the acquaitance at the same event, and I hadn’t noticed a difference in hair colour (different hue, same degree of darkness) between the two, possibly because I focus on faces and voices more than hair.

How did this error happen? Well, the stranger was a sibling of the acquaintance, of the same gender, build, age and hairstyle as the acquaintance, and both were attending the same event, and both have quite distinctive faces with a strong family resemblance in the entire face, not just in a couple of features. The family resemblance brings the siblings’ faces closer in similarity of appearance, while the shared distinctiveness of their faces pushes them away from resembling the faces of any randomly-chosen face of an unrelated person of the same race, age and gender. I would even argue that my misidentification was in fact a correct identification of pretty much the same face that happens to be shared by two people rather than the one individual, as is normally the case with faces, rather like the situation in which you meet by chance the twin of a person you know when you weren’t aware that the person you know has a twin. No, the siblings both now known to me are not twins. Yes, other people have made the same mistake in identification.

Is there anything to be learned from this mistake? I guess it shows that at least in my case, super-recognition is not about having a photographic memory or a memory for every single visual detail, but is more to do with detecting similarity, not just in one or a few visible features, but in an entire pattern made up of features, which as a whole can be distinctive, memorable and identifiable. Is super-recognition a superiority in memory for visual patterns?
