AGeneral Intelligence

Today we will look at this problematic concept known as "intelligence". What is it? Is there an "intelligence" that help us to solve all kinds of problems? Or are there

different intelligences that help us deal with particular problems and

solutions? What do you think?

I think it depends on other things, such as cultural background.

Indeed. There is also a body of research that states mental ability is a function of

social factors such as education and not one's inherent biological make-up. The

scientific community is devided on the issue. One of the beliefs behind the idea of

single entity³ "inteligence" is the concept of "General Intelligence" or "g". The

English psychologist Charles Spearman in the early 20th century made "g" stand for

a statistical⁴ measures of performance across a variety of tests. He found that the

same people who did well in variety of mental tests tended to use a part in their

brains that he termed "g".This "g" laid the foundation for the notion of a single

intelligence, allowing us to undertake everyday mental tasks. Can you think of any

problems inherent in this theory?

Well, for one thing, it seems there are a lot of t mental activities that go on and that we

can't always measure their activity so easily.

Ture enough. Nonetheless, a recent study seems to confirm Spearman's theory.

Reseach has found that a part of the brain called the "lateral prefrontal cortex" is the

only area of the brain to increase in blood flow when volunteers tackle complicated

puzzles. However, Spearman's concept is still highly controversial with many people

questioning both the the statistical process and the simplistic nature of "g"
