Otto Kretschmer Posted January 25 Share Posted January 25 Have any studies been done on individuals with very high ontelligence? How exactly are the brains of guys like Terence Tao or Ed Witten different from an average brain that makes them so smart? Is it about brain size? Size of some brain areas? Some unusual synaptic properties? Whatever? Link to comment Share on other sites More sharing options...

So many that you need to be more specific about what you're looking for. 18 minutes ago, Otto Kretschmer said: Is it about brain size? Size of some brain areas? Some unusual synaptic properties? Whatever? From what I've read, size is only a small factor. The way the various regions are "wired", and the ways the regions communicate with each other is much more important. 1 Link to comment Share on other sites More sharing options...
iNow Posted January 25 Share Posted January 25 The type of size measurement considered is also relevant. Overall volume seems to be less important than total surface area and complexity of the folds and convolutions, etc. Also, "intelligence" is a highly variable and oftentimes nebulous concept. Artists are often intelligent in different ways than mathematicians and plumbers are often intelligent in different ways from chefs or chemists, for example. 1 Link to comment Share on other sites More sharing options...

Well, it is a question what is being measured, isn't it? There is the concept of the savant syndrome, where folks can perform astonishing tasks in one particular area. Others do not excel in any one area but have massive breadth. That all being said, I think the biggest factor for any smart brain is training.

At the same time Terence Tao was already learning university level math by the time he was 9 years old and had a PhD at 21 and a professorship at 24. Those people simply are different from an average person. Link to comment Share on other sites More sharing options...

You claim he's different than average, but how much of that difference was because his father was a doctor and his mother was a maths and physics teacher? 1 Link to comment Share on other sites More sharing options...

Having support and tailor made education certainly helped him realize his potential. But it did not create it - he showed extreme math aptitude since age 2-3 so his brain somehow has to be wired differently... If education and support was the key here then the same pattern of lifetime achievement would repeat itself in other children. Yet there are thousands of math or physics teachers' kids who don't achieve nowhere near as much as Tao. Link to comment Share on other sites More sharing options...

Or his parents inclinations and methods weren't standard and their child benefitted from the focus. I'm not saying the "wiring" aspect isn't correct, but it seems like it's arguing more for "nature" and less for "nurture", and it's almost certainly quite a bit of both. 1 Link to comment Share on other sites More sharing options...

Any evidence that his parents' methods were non standard? To my knowledge little is known about his early life other that he showed extraordinary mathematical ability from an early age. I'm not saying nurture did not contribute to his success. But my reasoning tells me that in his case nature was the dominant factor. Link to comment Share on other sites More sharing options...

joigus Posted January 29 Share Posted January 29 From what I've read, neuronal migration, glial growth, etc are perhaps the identifiable biological factors at work when the frontal cortex is developing (up until about 25 yo in most individuals) that are very much affected by the environment. Nurture and nature are both part of Nature because, as George Carlin once pointed out, Nature includes everything, including the oft-misused and abused figure of speech involved in the dichotomy nature/nurture. Developmental processes don't occur in a Petri dish. So I agree with most people's observation here, if I understood correctly: Remove the nurture factor and the genius disappears. 1 Link to comment Share on other sites More sharing options...
TheVat Posted January 29 Share Posted January 29 The strong dependence on nurture is underscored by the studies of families (cognitive tests) which show a regression to the mean, in children. Link to comment Share on other sites More sharing options...

Especially when it comes to the brain. As we know, deprivation inhibits neuronal development. 1 Link to comment Share on other sites More sharing options...

CharonY Posted January 29 Share Posted January 29 1 hour ago, Otto Kretschmer said: Deprivation of what? Nutrition or information? Is this the case in developed countries? Well nutrition too of course. But things like sensory input and training. Early studies in the 40s have shown that children with less social interaction (in an orphanage) developed slower and exhibited reduced intellectual (and physical) development. The famous (and cruel) study by Harlow on macaques showed how social deprivation resulted in behavioural issues. In other words, the brain requires stimulation to develop. This not really new and on the neurological levels we also know that neural pathways and connections are formed because they are used (and trimmed when not). So the brain does need a sufficiently stimulating environment to fully blossom. And yes, that can be a problem in developed countries, if, say children do not interact enough with other folks, for example. And I am also a bit curious what effects the use of electronics, such as tablets and cell phones have in childhood. They are certainly stimulating in some ways but are also potentially limiting in others. 1 Link to comment Share on other sites More sharing options...

A genius is an outlier, it takes a combination of unusual circumstances for a genius to have any meaning at all, and even then some of them can't be trusted to cross the road safely.
