The painter is Esref Armagan. And he is here in Boston to see if a peek inside his brain can explain how a man who has never seen can paint pictures that the sighted easily recognise - and even admire. He paints houses and mountains and lakes and faces and butterflies, but he's never seen any of these things. He depicts colour, shadow and perspective, but it is not clear how he could have witnessed these things either. How does he do it?
...
Armagan was born 51 years ago in one of Istanbul's poorer neighbourhoods. One of his eyes failed to develop beyond a rudimentary bud, the other is stunted and scarred. It is impossible to know if he had some vision as an infant, but he certainly never saw normally and his brain detects no light now.
...
His paintings are disarmingly realistic. And his skills are formidable. "I have tested blind people for decades," says John Kennedy, a psychologist at the University of Toronto, "and I have never seen a performance like his."
...
Kennedy put Armagan through a battery of tests. For instance, he presented him with solid objects that he could feel - a cube, a cone and a ball all in a row (dubbed the "three mountains task") - and asked him to draw them. He then asked him to draw them as though he was perched elsewhere at the table, across from himself, then to his right and left and hovering overhead. Kennedy asked him to draw two rows of glasses, stretching off into the distance. Representing this kind of perspective is tough even for a sighted person. And when he asked him to draw a cube, and then to rotate it to the left, and then further to the left, Armagan drew a scene with all three cubes. Astonishingly, he drew it in three-point perspective - showing a perfect grasp of how horizontal and vertical lines converge at imaginary points in the distance. "My breath was taken away," Kennedy says.
...
Even more intriguing was the way in which drawing activated Armagan's visual cortex. It is now well established that when sighted people try to imagine things - faces, scenes, colours, items they've just looked at - they engage the same parts of their visual cortex that they use to see, only to a much lesser degree. Creating these mental images is a lot like seeing, only less powerful. When Armagan imagined items he had touched, parts of his visual cortex, too, were mildly activated. But when he drew, his visual cortex lit up as though he was seeing. In fact, says Pascual-Leone, a naive viewer of his scan might assume Armagan really could see.

That result cracks open another big nut: what is "seeing" exactly? Even without the ability to detect light, Armagan is coming incredibly close to it, admits Pascual-Leone. We can't know what is actually being generated in his brain. "But whatever that thing in his mind is, he is able to transfer it to paper so that I unequivocally know it's the same object he just felt," says Pascual-Leone.
...
We normally think of seeing as the taking in of objective reality through our eyes. But is it? How much of what we think of as seeing really comes from without, and how much from within? The visual cortex may have a much more important role than we realise in creating expectations for what we are about to see, says Pascual-Leone. "Seeing is only possible when you know what you're going to see," he says. Perhaps in Armagan the expectation part is operational, but there is simply no data coming in visually.

This article makes me wonder how much our preconceptions rule what our brain tells us we see?

Oh, and obviously, Armagan is quite skilled, though after the build-up in the article, I was disappointed in his actual work.

From what Wendy said, it's quite possible that words had so accurately described the images of the world that the blind artist was able to picture what they are like. Over a period of trial and error based on the reactions of sighted people his learning system would then begin to understand what works and what doesn't allowing him to build a picture in his imagination.

I am curious about how much assistance he has from sighted people while painting.
