I suspect that the difference between normal intelligence and so
called savant status is incentivation. This does not happen
naturally and ample good enough solutions exist that the individual
knows he is good enough. An injury forces the brain to manufacture
effective work arounds and this often is well done releasing a
surplus of specific talent.
Can we artificially generate such work arounds? We do know that
repetitive practice can undo known flaws.
Can we choose enhancements and should we? Memory skills have been
long trained for a range of reasons although it is not nearly as
important as it is cut out to be.
My own preference would be to have a string of enhancement protocols
that demanded a higher level of natural functionality. These could
be applied anytime, but preferably as early as worthwhile. Otherwise
we all have spotty development.
Is there a savant
inside all of us?
Savants have almost
super-human abilities in art, music or memory – and not all are
born that way. But is severe head trauma the only way to become a
‘sudden savant’?
By William
Langley
On Southport’s
stately seafront, the opening of a new art exhibition is drawing a
late summer crowd. Long and unusually complex in the planning, it
features the paintings of Tommy McHugh, an ex-builder from nearby
Liverpool whose work has attracted worldwide attention.
Despite the
appreciative buzz, Tommy, unfortunately, can’t be present. I later
find him in the intensive care unit of a hospital on the Wirral,
where he has been taken with acute pneumonia. A few weeks later he
is dead. The redoubtable, 62 year-old latecomer to the world of art
had been plagued with illness for some time, but harboured mixed
feelings about his afflictions. It was after a near-fatal stroke, 11
years ago, that he discovered – to no one’s greater surprise
than his own – that he could paint.
And paint not just as
an occasional pleasure, but with a furious, obsessive exactness that
took over his life and produced a stream of acclaimed works.
Psychologists, who looked at his case, considered him to be one of
the world’s foremost examples of “sudden savant syndrome” –
a rare, barely-understood phenomenon whereby damage to the brain
somehow unlocks a hidden talent.
There are so few
confirmed cases — perhaps 30 in the world – that plausible
explanations are hard to come by. Take Orlando Serrell, a
44-year-old from Virginia who was hit on the head by a baseball as a
boy, and later found he could do complicated calculations and
remember the precise weather conditions of any given day of the
year.
Or Tony Cicoria. An
orthopaedic surgeon from New York State, Dr Cicoria was struck by
lightning in 1994 as he chatted to his mother from an outdoor
telephone booth. Within weeks he became obsessed with classical
piano music and a few years later — despite no previous interest
in music beyond listening to rock songs – he made his public debut
as a pianist and composer in a solo recital.
What is the
explanation for all this? And does it – as some scientists now
believe – hold the promise of unleashing the inner talents of
everyone?
“What appears to
happen,” says Darold Treffert, a consultant psychiatrist from
Wisconsin who has studied such cases for 40 years, “is that
after severe trauma the brain rewires itself. When damage occurs in
one part of the brain it may be that other parts step in to
compensate and in doing so release dormant potential which manifests
itself as abilities that weren’t there – or weren’t known
about – before.”
McHugh’s upbringing
wasn’t the kind that nurtured an appreciation of arts and high
culture. One of 12 children born into a working-class family, he was
in regular trouble as a young man, fell into drug use, served time in
prison, and eventually made a career of sorts as a builder and
odd-job man. No one would have thought that his appreciation of art
went beyond the tattoos on his forearms.
But in 2001 Tommy
suffered a severe stroke, with haemorrhaging on both sides of his
brain. When he returned home he had no idea who he was. The face in
the mirror was one he didn’t recognise. The woman who said she was
his wife was a stranger. He found he could only speak in an elaborate
form of rhyme.
Then, as he groped
around in a world he no longer knew, the emptiness was replaced by a
huge, urgent creative rush. He began painting and hasn’t stopped.
He covered the walls, the doors and the ceilings of his house in
vivid, intricate patterns and when he ran out of space, he re-covered
what he had already painted. “It was as though a balloon had
popped,” he told me, propped up in a bed in Arrow Park Hospital. “I
could see the beauty of the world. I knew who I was. The man I used
to be had gone forever. I don’t even know who he was.” Tommy
produced not only paintings, but sculptures and collages, and his
rhymes began to fashion themselves into poetry.
Dr Mark Lythgoe, a
neurologist at University College London, who has studied the McHugh
case, says: “It may be that the brain damage that Tommy sustained
has caused disinhibition of brain pathways, allowing his creativity
to surface. Perhaps whatever was keeping his artistic talents hidden
or dormant has been damaged just enough to allow them to pour
through.”
Tommy himself spoke
like a born-again convert, desperate for others to hear the Good
News. “This isn’t something special to me,” he said. “This is
inside everyone, but they are too frightened to let it out. Then
something happens to you and it comes out anyway.”
The results are
sometimes bizarre. Last year, Chris Birch, a 19-stone rugby player
from South Wales, told how he suffered a stroke and woke up gay. The
26-year-old proceeded to ditch his girlfriend, pack in his job and
retrain as a hairdresser. Other patients have started speaking in
foreign accents. But researchers are most interested in those who
wake up with savant-type abilities.
In 2003, Bruce Miller,
a professor of neurology at the University of California, San
Francisco, discovered that some patients suffering from a
degenerative brain disorder called frontotemporal dementia (FTD),
developed sudden and remarkable artistic talents as their conditions
progressed. One of the cases he studied involved Anne Adams, a
renowned Canadian biologist, who – as FTD gnawed at the cognitive
networks of her brain – lost the power of speech, but gained
extraordinary artistic skills. “This shows how plastic our brain
is,” explained Miller in a report published in the magazine Brain
four years ago. “If you turn off the language circuits, you may
have increased activities in other areas.”
Elsewhere, scientists
are now investigating whether it’s possible to replicate this
change without, of course, damaging the patient. Dr Allan Snyder, of
the University of Sydney, has created a machine called the Medronic
MagPro which attempts temporarily to replicate the deterioration
caused by FTD, by sending precise electromagnetic pulses into the
frontal lobes of the brain. Snyder calls it “a creativity
amplification machine”.
One guinea pig who
underwent Snyder’s tests was asked to draw a sequence of pictures
of cats. He reported: “Two minutes after I started the first
drawing, I was instructed to try again. After another two minutes I
tried a third cat, and then in due course a fourth. Then the
experiment was over, and the electrodes were removed. I looked down
at my work. The first felines were boxy and stiffly unconvincing, but
after I had been subjected to about 10 minutes of transcranial
magnetic stimulation, their tails had grown more vibrant; their faces
were personable and convincing.” Other patients, says Snyder, have
experienced enhanced abilities in memory, visual skills and
mathematical calculation.
Savants are usually
defined as people – predominantly men – who possess unusual
powers of memory, calculation or artistic skill in conjunction with
severe mental deficiencies. The condition presents in men much more
often than in women because, according to some scientists, high
levels of testosterone in the male foetus cause damage to the left
hemisphere of the brain. Treffert describes savant abilities as “deep
but narrow”, and many struggle with the wider challenges of life.
Sudden savant syndrome appears to add a further dimension to the
phenomenon, as most have had relatively normal lives until the
savantism hits them.
If there is a Leonardo
lurking in all of us, or a Mozart writing silent scores in our heads,
it raises one big, so far unanswered question: where does such talent
come from? How can someone such as Cicoria, who had undergone no
musical training or demonstrated any previous hint of talent,
suddenly start composing sonatas and concertos?
The
consensus-shattering answer may lie in genetics. “The only way this
can be explained,” says Treffert, “is through the genetic
transmission of knowledge. We know this is the case in the animal
kingdom; creatures manage incredible feats of navigation [without
anyone] teaching them how to do it. Someone in the family of a Tommy
McHugh must have had these abilities.” This theory vastly expands
existing assumptions of what human DNA can do. But even if it can be
proved, it’s hard to explain the astonishing capabilities of men
like Orlando Serrell.
Serrell is currently
out of work, having recently lost his job as a caretaker in Newport
News, Virginia. He tells me he had hoped his abilities would open up
opportunities, possibly with the FBI or even as a stage novelty act,
but after an initial burst of interest, nothing has developed.
“Some people, you
know, they lose consciousness, go into a coma, things like that, and
when they wake up, they find they are different people,” he says.
“But it wasn’t like that with me. I was playing in the park, and
someone threw [a] baseball and it hit me at the front of the head,
but I wasn’t knocked out. I just lay down and my head hurt bad, but
I got up and carried on the game, and it was only about a month later
that I found I could do this stuff.”
What Serrell can do is
instantaneously put a day to any date since the accident and recall
the weather, where he was and what he was doing. Doctors who have
studied him say this ability is vastly beyond the capacity of normal
human memory. Nothing known to science explains it, and it is hard to
see how genetics could.
“I’m the same
guy,” he says. “I don’t feel different in any other way. I
don’t even think of myself as a savant, I just feel I have a gift
that I found by accident. Beyond that I can’t explain it.” Nor,
adequately, can Cicoria.
A self-described
“rock-and-roll kind of guy”, Cicoria, whose story was recounted
in the neurologist Oliver Sacks’s 2007 book, Musicophilia:
Tales of Music and the Brain, recovered from the physical effects of
the lightning strike but soon began to feel strange activity in his
brain: “like it was one of those old-fashioned TV sets that picked
up interference, and you had to whack it to get a good picture.”
What came out of the
fuzz and crackle was a sudden desire for the finest classical piano
music. “I might be a respectable physician on the outside, but
inside I’m a biker dude,” he says. “I’d had a couple of music
lessons when I was a kid, but that was all. I couldn’t understand
why I wanted to hear this stuff. So I went to the music store, and
bought some CDs, and then I felt that wasn’t enough and I wanted to
play it for myself, so I bought the sheet music and then a piano, and
began to learn how to play.
“Then, as I played,
other music started coming through in my head, and I understood that
I needed to write it down.” Today, Dr Cicoria, 60, is an
accomplished composer and pianist who has given dozens of
well-received recitals. “Exactly what happened to me, I’ll never
know,” he says, “but I’m glad it did.” This is how it tends
to be in the world of the savants. Brilliance and talent abound, but
no one can quite explain what is going on.
