Many of us have heard about the IQ test, which shows the level of human intelligence. However, most of them know almost nothing about him. Before you begin the test, you must definitely find out what IQ should be like a normal person.
general information
The abbreviation IQ stands for intelligence quotient, which can be translated as "amount of intelligence." In the Russian-speaking language environment, the established expression “intelligence coefficient” is more often used. However, it is believed that in order for the results to be as truthful as possible, and they really can be trusted, it is worth taking into account not only the results of the test itself. Factors such as age and gender must also be considered.
Many also believe that the results of this test more likely show a person’s propensity for a particular type of task, rather than actual intellectual abilities. Therefore, you can prepare for it by solving puzzles that resemble those presented in tasks.
Story
Attempts to study the IQ of a normal person began in the 30s of the last century. Researchers have taken several attempts to determine the coefficient of intelligence through various experiments. Scientists tried to find a pattern that would link the processes of the central nervous system, reaction characteristics and mental abilities, even taking into account the size and weight of the brain. In addition, they studied the relationship of the coefficient of intelligence of parents and children, its relationship to social origin, age, and so on.
IQ test today
At present, it is generally accepted that the coefficient of mental intelligence depends on many factors, for the most part on heredity. However, the IQ level of a normal person can be increased by solving various tasks and tests. In addition, in the modern world, not so much intelligence is a source of success as motivation and perseverance. An important role is also played by individuality, determination and ambition. Nevertheless, it is a high level of intelligence that can help in solving difficult life circumstances and contribute to more advantageous conditions.
Despite the fact that the first tests were created exclusively with lexical exercises, today they use a lot of different tasks. Among which are exercises for counting, logical series, the ability to find a missing geometric figure, the ability to recognize a fragment, remember facts, technical drawings and determine the missing letter.
How much IQ does a normal person have
The average level of human intelligence ranges from 100 to 120 units, which is about half of the correctly solved problems. The person who will cope with all the 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 a person who passes it. By identifying the category in which the subject has the smallest level of ability, you can help him identify gaps in his abilities, practice with different types of tasks and raise the intelligence coefficient.
First tests
For the first time, V. Stern spoke about the coefficient of intelligence, who considered the definition of the level of skills on the Binet scale incorrect, since he had a serious drawback regarding age. The scientist proposed to determine the abilities of a person, dividing mental age by chronological. The IQ test of a normal person demonstrates a quantitative assessment of an individual’s ability in relation to an average representative of the same age.
Average performance
It is considered that the IQ test does not show a person’s level of erudition, but only an assessment of general indicators. They are designed specifically to get average results. The normal person’s IQ may vary, but there are common indicators. So, about half of the people who have 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 graduation rate of American universities is 115 points, excellent students - from 135 to 140. The IQ level, which is less than 70 points, is usually considered a sign of mental retardation.
Output
The IQ test shows the level of development of human abilities , but it should not be considered that they in any way show the level of erudition. They only help to understand in which area and in which direction a person needs to develop.
It is believed that the IQ level of a normal person varies from 90 to 120 conventional units. Most often, the Eysenck test is used to determine the coefficient of intelligence. However, do not forget that the most accurate will be the results obtained during the very first passage of the test, and all subsequent attempts will only distort them.
