EspañolAUTISTIC SAVANT
:
An 'autistic savant' (historically described as 'idiot savant') is a person with both autism and 'Savant Syndrome'. Savant Syndrome describes a person having both a severe developmental or mental handicap but with extraordinary mental abilities not found in most people. This means a lower than average general intelligence (IQ) but very high narrow intelligence in one or more fields. Savant Syndrome skills involve striking feats of memory and arithmetic calculation and sometimes include unusual abilities in art or music. Savant Syndrome is sometimes abbreviated as "savantism" or "'KC'", and individuals with the syndrome are often nicknamed ''savants''. This is a source of confusion since a ''savanter'' is a person of learning, especially one of great knowledge in a particular subject.
Savant Syndrome is usually recognized during childhood and found in children with autism and other developmental difficulties. However, it can also be acquired in an accident or illness, typically one that injures or impairs the left side of the brain. Some research suggests that it can be induced, which might support the view that savant abilities are latent within all people but are obscured by the normal (i.e. majoritive) functioning intellect. Using repetitive transcranial magnetic stimulation, Allan Snyder has found some evidence that savant-like skills can be improved in a healthy individual by a temporary disruption of the left front part of the brain - at least with some of the probates. [1]
Most autistic savants have very extensive mental abilities called ''splinter skills''. However, it is important to notice that people with a high general intelligence can demonstrate the same skills; savant disabilities are not necessary for these skills. They can recall facts, numbers, license plates, maps, and extensive lists of sports and weather statistics after only being exposed to them once. Some savants can mentally note and then recall perfectly a very long sequence of music, numbers, or speech. Some, dubbed mental calculators, can do exceptionally fast arithmetic, including prime factorization. Other skills include precisely estimating distances and angles by sight, calculating the day of the week for any given date over the span of tens of thousands of years, and being able to accurately gauge the passing of time without a clock. Most autistic savants have a single special skill while others have multiple skills. Usually these abilities are concrete, non-symbolic, right hemisphere skills as opposed to left hemisphere skills that tend to be more sequential, logical, and symbolic.
Why autistic savants are capable of these astonishing feats is not quite clear. Some savants have obvious neurological abnormalities (such as the lack of corpus callosum in Kim Peek's non-autistic brain), but the brains of most savants are anatomically and physiologically normal; at least, there is no abnormality that modern science can detect. Some neurologists (see e.g., Oliver Sacks) theorize that those with savantism utilize an "innate" modular arithmetic to compute such complex problems as what day of the week a distant date (for instance, July 11th, 88182) will fall on.
There are only about 50 - 100 ''recognized'' prodigious savants in the world. [2]
