Many of us have heard about the test on IQ, which indicates the level of human intelligence.However, most of practically nothing about it know.Before you take up the passage of the test, it is necessary to know what should be a normal IQ in humans.
General
Abbreviation IQ stands for intelligence quotient, which can be translated as "the amount of intelligence."In the Russian-speaking linguistic environment often used well-established term "intelligence quotient."However, it is believed that, in order to maximize the results were true, and they really could be trusted, it is worth taking into consideration not only the results of the test.We must also take into account factors such as age and sex.
Many also believe that the results of this test show a more human propensity for a particular type of job, and not the actual intellectual abilities.Therefore, it can be prepared by solving puzzles that remind presented a quest.
history
attempts to study the normal IQ person began in the 30s of the last century.The researchers took a number of attempts to determine the IQ through a variety of experiments.Scientists are trying to find a pattern that would have linked the processes of the central nervous system response characteristics and mental abilities, even take into account the size and weight of the brain.In addition, they studied the relationship of IQ of parents and children, his attitude to social origin, age, and so on.
IQ-test today
Currently accepted that the intelligence quotient of intelligence depends on many factors, mostly by heredity.However, IQ is a normal person can be increased by solving various tasks and tests.In addition, in today's world is not so much intelligence is the source of success as motivation and persistence.An important role is also played by personality, determination and ambition.Nevertheless, it is a high level of intelligence can help in dealing with difficult life circumstances and contribute to a more advantageous conditions.
Despite the fact that the first tests created exclusively with lexical exercises, today they use a wide variety of tasks.These include exercise into account, the logical rows, the ability to find the missing geometric shape, the ability to recognize the fragment remember facts tehchertezhi and identify the missing letters.
How IQ in the normal person
average level of human intelligence varies between 100 and 120 units, which is about half of the true problem solving.The man who will cope with all tasks, receives 200 points.In addition to the level of intelligence test measures and other factors, it helps to reveal the thinking of a man who runs it.It defines the category in which the subject has the smallest level of abilities can help them identify gaps in its ability to train with different types of jobs, and raise IQ.
first tests
the first time spoke about the IQ Stern, who considered the definition of skill level on a scale of Binet's wrong, because it has a serious shortcoming relating to age.The scientist proposed to determine a person's ability, dividing the mental age by the chronological.IQ-test normal person shows a quantitative assessment of the individual's abilities in relation to the average representative of the same age.
Average
rightly believe that IQ test does not show the level of erudition of man, but rather assess the overall performance.They are specifically designed to obtain the distribution of results from the average.IQ normal person can vary, but there are common indicators.Thus, about half the people who passed the test showing the results of from 90 to 100 points, a quarter - below 90 and another quarter - greater than 110 units.The average graduates of American universities is 115 points, honors - from 135 to 140. The level of IQ, which is less than 70 points, it is generally considered a sign of mental retardation.
Conclusion
IQ-test shows the level of development of human capabilities, but we should not assume that they are in any way indicate the level of erudition.They only help to understand, in what area and in what direction a person must develop.
believed that IQ is a normal person varies from 90 to 120 conventional units.Most often used definition of IQ test Eysenck.But do not forget that the most correct results will be obtained in the first pass the test, and all subsequent attempts will only distort them.
