What is the normal person's IQ?

Many of us have heard about the test on IQ, whichshows the level of intelligence of a person. However, most people know practically nothing about him. Before you start the test, you need to know what the IQ should be for a normal person.

general information

The abbreviation IQ stands for intelligencequotient, which can be translated as "the amount of intelligence". In the Russian-speaking linguistic environment, the established expression "intelligence coefficient" is used more often. However, it is believed that in order for the results to be as true as possible and they can really be trusted, it is worth taking into account not only the results of the test itself. It is necessary to take into account factors such as age and gender.

Many also believe that the results of this testrather show the person's propensity to a specific type of tasks, rather than actual intellectual abilities. Therefore, you can prepare for it, solving problems that resemble those presented in the tasks.

History

Attempts to study normal man's IQ have begunback in the 30s of last century. The researchers made a number of attempts to determine the intelligence factor through various experiments. Scientists tried to find a regularity that would connect the processes of the central nervous system, the characteristics of the reaction and mental abilities, take into account even the size and weight of the brain. In addition, they studied the interrelation between the intelligence coefficient of parents and children, its relation to social origin, age, and so on.

IQ test today

At present, it is generally accepted thatthe ratio of mental intelligence depends on many factors, mostly on heredity. However, the level of IQ of a normal person can be increased by solving various tasks and tests. Besides, in the modern world, not so much intellect is a source of success, as much as motivation and perseverance. Individuality, determination and ambition also play an important role. Nevertheless, it is the high level of intelligence that can help in solving difficult life circumstances and contribute to more favorable conditions.

Despite the fact that the first tests were createdexclusively with lexical exercises, for today in them a lot of various tasks are used. Among which are exercises on the account, logical series, the ability to find the missing geometric figure, the ability to recognize the fragment, memorize the facts, the technical drawings and determine the missing letter.

How many IQ of a normal person

The average level of human intelligence varies froman interval of 100 to 120 units, which is about half of the correctly solved problems. The person who copes with all tasks gets 200 points. In addition to the level of intelligence, the test determines other indicators, it helps to identify the way of thinking of the person who passes it. Having determined the category in which the subject has the smallest level of abilities, one can help him identify gaps in his abilities, train with different kinds of tasks and raise the intelligence factor.

First tests

For the first time I began talking about the coefficient of intelligence. Stern, who considered the definition of the level of skills on the Binet scale incorrect, because he had a serious defect concerning age. The scientist proposed to determine the abilities of a person, dividing the mental age into a chronological one. The normal person's IQ test demonstrates a quantitative assessment of a person's abilities relative to the average representative of the same age.

Average

It is rightly considered that the IQ test does not showlevel of human erudition, but only an assessment of the overall indicators. They are designed specifically to get the distribution of results with an average. IQ of a normal person can vary, however, there are usual indicators. So, about half of the people who passed the test show a result equal to 90 to 100 points, a quarter - below 90, and the other quarter - above 110 units. The average rate of graduates of American universities is 115 points, the excellence - from 135 to 140. The level of IQ, which is less than 70 points, is usually considered a sign of mental retardation.

Conclusion

IQ-test shows the level of development of abilitiesperson, but we should not assume that they somehow show the level of erudition. They only help to understand in which area and in what direction a person needs to develop.

It is believed that the level of IQ of a normal personvaries from 90 to 120 conventional units. Most often, the Eysenck test is used to determine the intelligence factor. However, do not forget that the most accurate will be the results obtained at the very first test, and all subsequent attempts will only distort them.
