According to results of a study in children and adolescents, intelligence is just an interview

The development of general intelligence depends on physical parameters of the cerebral cortex.

Numerous studies have confirmed that the degree of development of human cognitive abilities largely determined by the internal structure of certain brain regions .

However, the relationship between cortex thickness and level of intelligence was not studied enough, and that all work is limited to study only a relatively small group of subjects.

So we can ask the following question: Is intelligence one or there are multiple intelligences, and what its biological basis? neuroimaging techniques that allow scientists to explore harmlessly living people's brains are allowing answers to questions like this, they have a clear social impact.

Recent research conducted by a team of specialists McGill University (Canada), University of California at Irvine (USA ) and University of Edinburgh (Scotland), completed the study, the scientists managed to gather the final data from medical examinations 216 healthy children and adolescents in the U.S. from ages 6 to 18 years.

analysis of the results allowed the specialists to separate certain areas of the cerebral cortex, which truly cortical thickness influence on specific cognitive abilities. Enel

study, experts were based on the results of four subtests that are used widely in modern psychology Wechsler test (used to assess the general level of intellect of children and adults ) and the magnetic resonance tomographic data. The diverse series of tests were of a verbal, visual-spatial and numerical. It is scored for each of these kinds of tasks, but also a general ability index for each subject. The result showed that a more notable link between the intellect and the thickness of the cerebral cortex observed in those areas responsible for processing incoming information from different areas of the brain. The final conclusion was surprising was that when considering canceling scores separate the influence of g, relationships with cortical thickness disappear.

"What remains when discounted the overall capacity (g) is noise-free value for the brain "concludes Colom. "If someone is very good with the language is much more likely than not that also what is with numbers and visuospatial processing," he adds. "The fact that they use verbal, numerical visual-spatial or not really important to understand our intelligence relationships with biology, but the fact that the overall capacity og capture more or less intensity. "

therefore seems that there is a collection of separate abilities, but a powerful general capacity (called g) performance conditions in various situations that require the use of the intellect.

However, "media gurus as Howard Gardner, Robert Sternberg or Daniel Goleman have convinced many people otherwise, "says Roberto Colom, Professor of Psychology Autonomous University of Madrid , has participated, along with other researchers of these countries in a study to be published in the journal NeuroImage. Authors such as Gardner

recalls Colom, have argued that there is nothing like a general intellectual ability, but on the contrary, some people excel in the use of language, while others highlight the numbers or activities that require processing visuospatial. Someone may well be awkward with exceptional language and numbers, they said.

addition, the researchers note that the results obtained can be used to develop the theory to explain the decline in cognitive function seen in the elderly and psychiatric patients.

These results should not be seen as conflicting as to the evidence of the functional specialization of regions cerebral cortex, say the authors, whose first author is Sheriff Karama, McGill University (Canada) . Just refer to the thickness of the crust, which is thought to reflect the density and distribution of neurons and other cells and fibers of the nervous system.

The definition of the sociological intelligence Linda S. Gottfredson Gottfredson

in 1997 defined human intelligence as "u na very general mental capability that, among other things, includes the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas , learn quickly and learn from experience. It is not only learning from books, limited academic ability, or do well on tests (tests). On the contrary, it reflects a broader and deeper capacity to encompass what surrounds us . "
