New research shows that measuring the level of intelligence and quite absurd that there is no IQ and that the concept of "intelligence quotient" completely incorrectly, according to a survey whose results were reported by health portal Greatest.
The study included one hundred thousand volunteers who worked intelligence test, recording capacity of memory, reasoning, concentration, planning skills ... In addition, some of the respondents agreed that their brains were being scanned by MRI scanners.
The results showed that there is no precise scale with levels of IQ, which could equal rank all abilities. The situation is further aggravated by the fact that for each of the investigated "feature" activated different parts of the brain.
It was found that the concept of intelligence can be "broken" into three parts - short-term memory, verbal ability and reasoning abilities.
In addition, this research studied the effects of factors such as age, gender and health habits on cognitive abilities. That has been proven that people in their twenties better deal memory and reasoning tests than sixty years old.
Interestingly, the respondents who said they often play video games in these areas recorded better results. On the other hand, smokers are much worse when it comes to short-term memory and verbal skills.
