We are all different.The differences are manifested in the appearance, physical and psychological characteristics and, of course, intelligence.International exponent of intelligence is the IQ.This concept was introduced in 1912 by Stern - scientists from Germany.Note that most people have an average IQ, and only a few - high or low.For this reason, in a society far less talented scientists, than, say, office clerks.
average IQ is 100 points.However, the values of 90 to 110 are permissible norm.Intelligence quotient is determined by special tests.Their implementation is given a certain amount of time.It should be noted, however, that the great interest shown by the level of human intelligence, has contributed to the creation of many different types of jobs, which is why the results of the different tests from one another by one and the same person can vary significantly.
noticed that the repeated performance of tasks for a certain level of intelligence subsequently able to increase the number of correct answers, the speed of the decision and, accordingly, the very figure.Before you check your IQ, better to solve some typical problems: after all, they have certain characteristics, and an inexperienced person finds it difficult to cope with them the first time.
Hans Eysenck is the author of the best-known and popular test.According to his system of determining the level of intelligence, the maximum IQ does not exceed 180 points.However, it is believed that the most accurate results obtained by other researchers have jobs, including Cattell, Wexler and Ravenna.
According to some studies, the average IQ in the world today is rarely more than 90 points, although ideally this value is normal for teens 14-15 years old.Others data show that the value of the coefficient of intelligence, say, students who have just graduated from American colleges is about 115 points.And this, despite the deep-seated social stereotype that Americans do not differ a special mind.According to official figures the average IQ of Russians - 113 points.
lowest level of intelligence are residents of Australia (with the exception of Botswana).But the maximum IQ was recorded in Japan, Korea and China.This is not surprising, especially considering the level of development of scientific and technological revolution in these countries.Researcher Richard Lynn studied the level of intelligence is not among the nations, and among the individual races.So, to say that Australians - the most stupid people - is meaningless, because the indigenous population there is about 2.5%, while in the eastern countries, the figure is 70%.
proved that an IQ affects heredity.In addition, the results of tests, with the help of which is determined by the level of intelligence, depend on the environment.
It's quite strange, but according to research, breast-feeding has a positive effect on child's IQ and his level of the mother.
In general we can say that the average person can affect the level of their intelligence through regular mental stress, proper nutrition and a healthy lifestyle.
