The concept of "intelligence quotient" was introduced by the German psychologist William Stern. He used IQ as an acronym for the term Intelligenz-Quotient - the IQ was a score obtained from a series of standardized tests conducted under the guidance of a psychologist to determine the level of intelligence.

Mind Research Pioneers

At first, psychologists doubted that the human mind could be measured, much less accurately. While interest in measuring intelligence goes back thousands of years, the first IQ test has only recently appeared. In 1904, the French government asked the psychologist Alfred Binet to help determine which students were most likely to have difficulty in school. The need to establish the intelligence of schoolchildren arose so that all of them could receive a compulsory elementary education. Binet asked colleague Theodore Simon to help him create a test that would focus on practical matters: memory, attention and problem solving - things that children are not taught in school. Some answered more difficult questions than their age group, and therefore, on the basis of observational data, the now classical concept of mental age has emerged. The result of the work of psychologists - the Binet-Simon scale - became the first standardized IQ test.

By 1916, Stanford University psychologist Lewis Terman had adapted the Binet-Simon scale for use in the United States. The modified test was called the Stanford-Binet Intelligence Scale and became the standard intelligence test in the United States for several decades. Stanford - Bean uses a number known as IQ - intelligence quotient to represent an individual's score.

How to calculate intelligence?

IQ was originally determined by dividing the mental age of the person taking the test by their chronological age, and multiplying the quotient by 100. It goes without saying that this only works (or works best) for children. For example, a child with a mental age of 13.2 years and a chronological age of 10 years has an IQ of 132 and is eligible to enter Mensa (13.2 ÷ 10 x 100 = 132).

During World War I, the United States Army developed several tests to select recruits for specific jobs. The Army's "Alpha" test was a written test, while the "Beta" test was given to illiterate recruits.

This and other IQ tests have also been used to test new immigrants coming to the US from Ellis Island. Their results were used to fabricate false generalizations about the "surprisingly low intelligence" of immigrants from Southern Europe and Jews. These results in 1920 led to proposals by the "racially motivated" psychologist Goddard and others to Congress to impose restrictions on immigration. Although tests have only been carried out on English language, and the vast majority of immigrants did not understand it, the United States government deported many thousands of deserving people who were labeled as "unfit" or "undesirable". And this happened a decade before Nazi Germany started talking about eugenics.

Psychologist David Wexler was dissatisfied, in his opinion, with the limited Stanford-Binet tests. main reason this was the only assessment, its emphasis on time limits, and the fact that the test was designed specifically for children, and therefore not suitable for adults. As a result, during the 1930s, Wexler developed a new test that was known as the Wexler Bellevue Intelligence Scale. The test was subsequently revised and became known as the Wechsler Adult Intelligence Scale, or WAIS. Instead of one overall assessment, the test created an overall picture of strong and weaknesses subject. One advantage of this approach is that it also provides useful information. For example, in some areas and low in others, they indicate the presence of specific learning disabilities.

WAIS was psychologist Robert Wechsler's first test, while the WISC (Wechsler Intelligence Scale for Children) and the Wechsler Preschool Intelligence Scale (WPPSI) were developed later. The adult version has since been revised three times: WAIS-R (1981), WAIS III (1997) and in 2008 WAIS-IV.

Unlike tests based on chronological and mental age scales and standards, as in the case of Stanford-Binet, all versions of WAIS are calculated by comparing the test person's score with that of other test subjects of the same age group. The average IQ score (worldwide) is 100 with 2/3 of the scores in the "normal" range of 85 to 115. WAIS norms have become the standard in IQ testing and are therefore used by the Eysenck and Stanford-Binet tests, with the exception that the standard deviation in it is not 15, but 16. In the Cattell test, the deviation is 23.8 - it often gives very flattering IQs, which can mislead uninformed people.

High IQ - high intelligence?

The intelligence quotient for the gifted is determined using special tests that provide psychologists with many useful information. Many of them have an average score of 145-150, and a full range between 120 and 190. The test is not designed for results below 120, and more than 190 points are very difficult to interpolate, although this is possible.

Paul Kooijmans from the Netherlands is considered the founder of upper range IQ tests, and he is the creator of most of the original, and now classic, tests of this type. He also founded and administers the super-high IQ societies Glia, Giga, and Grail. Among Kooijmans' most famous and popular tests are the "Genius Test", the "Nemesis Test", and the "Kooymans Multiple Choice Test". Paul's presence, influence and participation is a must, it's an integral part of the spirit of ultra-high IQ tests and his communities at large. Other classic IQ test gurus are Ron Hoeflin, Robert Lato, Laurent Dubois, Mislav Predavec and Jonathon Wye.

There are different types of thinking that manifest themselves differently at different levels. People have different skills and levels of intelligence: verbal, typical, spatial, conceptual, mathematical. But there are also different ways of their manifestation - logical, lateral, convergent, linear, divergent and even inspired and ingenious.

Standard and elevated IQ test reveal common factor intellect; but in high-level tests it is defined in different ways.

Often talk about high scores IQ who call the IQ of geniuses, but what do these numbers really mean and how do they add up? What IQ score is a sign of genius?

  • A high IQ is any score above 140.
  • The IQ of a genius is over 160.
  • Great genius - score equal to or greater than 200 points.

High IQ is directly related to academic success, but does it have an impact on success in life in general? How much luckier are geniuses than people with lower IQs? Some experts believe that compared to other factors, including emotional intelligence, IQ is of lesser importance.

Breakdown of IQ scores

So how exactly are IQ scores interpreted? The average IQ test score is 100. 68% of IQ test results fall within the standard deviation of the mean. This means that most people have an IQ between 85 and 115.

  • Up to 24 points: profound dementia.
  • 25-39 points: severe mental disability.
  • 40-54 points: moderate dementia.
  • 55-69 points: mild mental disability.
  • 70-84 points: borderline mental disorder.
  • 85-114 points: average intelligence.
  • 115-129 points: above average level.
  • 130-144 points: moderate giftedness.
  • 145-159 points: highly gifted.
  • 160-179 points: exceptional giftedness.
  • more than 179 points: profound giftedness.

What does IQ mean?

When talking about intelligence tests, IQ is referred to as "giftedness scores". What do they represent in assessing IQ? To understand this, it is important to first understand testing in general.

Today's IQ tests are based largely on original tests developed in the early 1900s by the French psychologist Alfred Binet to identify students in need of extra help.

Based on his research, Binet developed the concept of mental age. Children of some age groups quickly answered questions that were usually answered by older children - their mental age exceeded chronological age. Binet's measurements of intelligence were based on the average abilities of children in a certain age group.

IQ tests are designed to measure a person's ability to solve problems and reason. The IQ score is a measure of fluid and crystallized intelligence. The scores indicate how well the test was done compared to other people in that age group.

Understanding IQ

The distribution of IQ scores follows a Bell curve, a bell-shaped curve whose peak corresponds to the largest number of test scores. The bell is then lowered on each side - scores are below average on one side and above average on the other.

This is equal to the average score and is calculated by adding all the results and then dividing them by the total number of points.

Standard deviation is a measure of variability in a population. A low standard deviation means that most of the data points are very close to the same value. A high standard deviation indicates that the data points tend to be farther from the mean. In IQ testing, the standard deviation is 15.

IQ increases

With each generation, IQ increases. This phenomenon is called the Flynn effect, named after researcher Jim Flynn. Since the 1930s, when standardized tests became widespread, researchers have noted a steady and significant increase in test scores in people around the world. Flynn suggested that this increase is due to an improvement in our ability to solve problems, think abstractly, and use logic.

According to Flynn, past generations have mostly dealt with the concrete and specific problems of their immediate environment, and modern people think more about abstract and hypothetical situations. Not only that, but approaches to learning have changed dramatically over the past 75 years, and more people are, as a rule, engaged in mental work.

What do the tests measure?

IQ tests assess logic, spatial imagination, verbal reasoning, and visual ability. They are not intended to measure knowledge in specific subject areas, since an intelligence test is not something that can be learned in order to improve one's score. Instead, these tests assess the ability to use logic to solve problems, recognize patterns, and quickly make connections between different information.

Although one often hears that prominent figures, such as Albert Einstein and Stephen Hawking have IQs of 160 or higher, or some presidential candidates have specific IQs, these numbers are just estimates. In most cases, there is no evidence that these well-known individuals have ever taken a standardized IQ test, let alone made the results public.

Why is the average score 100?

Psychometricians use a process known as standardization to compare and interpret IQ scores. This process is carried out by conducting a test on a representative sample and using its results to create standards or norms against which individual scores can be compared. Because the median score is 100, professionals can quickly compare individual scores to the median to see if they fall within a normal distribution.

Grading systems can vary from one publisher to another, although many tend to follow the same grading system. For example, on the Wechsler Adult Intelligence Scale and on the Stanford-Binet test, scores in the range of 85-115 are considered "average".

What exactly do the tests measure?

IQ tests are designed to assess crystallized and fluid mental abilities. Crystallized includes knowledge and skills acquired throughout life, and mobile - the ability to reason, solve problems and comprehend abstract information.

Fluid intelligence is said to be independent of learning and tends to decrease over time. adulthood. Crystallized, on the other hand, is directly related to learning and experience and constantly increases over time.

The intelligence test is administered by licensed psychologists. Exist different kinds tests, many of which include a range of subtests designed to assess math ability, language skills, memory, reasoning skills, and processing speed. Their scores are then combined to form a total IQ score.

It is important to note that while average, low, and genius IQs are often spoken of, there is no single test for intelligence. Many different tests are used today, including the Stanford-Binet, the Eysenck Adult Intelligence Scale, and the Woodcock-Johnson Cognitive Ability Test. Each of them differs in what exactly and how it is evaluated, and how the results are interpreted.

What is considered low IQ?

An IQ equal to or below 70 is considered low. In the past, this IQ was considered the standard for mental retardation, an intellectual disability characterized by significant cognitive impairment.

Today, however, IQ by itself is not used to diagnose intellectual disability. Instead, the criterion for this diagnosis is low IQ, with evidence that these cognitive limitations existed before the age of 18 and involved two or more adaptive areas such as communication and self-help.

About 2.2% of all people have an IQ score below 70.

So what does it mean to have an average IQ?

IQ level can be a good general measure of reasoning and problem solving ability, but many psychologists suggest that tests don't reveal the whole truth.

Among the few things they fail to measure are practical skills and talents. A person with an average IQ may be a great musician, artist, singer, or mechanic. The psychologist developed the theory of multiple intelligences designed to address this shortcoming.

In addition, the researchers found that IQ can change over time. A study of the intelligence of adolescents with a gap of 4 years gave results, the values ​​of which varied by 20 points.

IQ tests also do not measure curiosity and how well a person understands emotions and owns them. Some experts, including the writer, suggest that emotional intelligence (EQ) may be even more important than IQ. Researchers have found that a high IQ can indeed help people in many areas of life, but does not guarantee success in life.

So there is no need to worry about the lack of genius, since the vast majority of people are not geniuses. Just as a high IQ does not guarantee success, an average or low IQ does not guarantee failure or mediocrity. Other factors such as hard work, resilience, perseverance and general attitude are important pieces of the puzzle.

IQ tests are almost never used in Russia. But the term itself has become widely known.

Most people know that IQ (read "IQ") is a measure of the strength of human intelligence. But what does it mean and how is it calculated?

It all started with the French psychologist Alfred Binet in 1905. He worked with mentally retarded youth and, together with his colleague Theodore Simon, developed a technique for measuring psychological age young people, which in the case of their wards differed from the biological age.

Then, in 1912, the German psychologist William Stern developed a method for determining the ratio of intellectual age to biological age. He found that this ratio remained virtually unchanged in the process of growing children.

This ratio became known as the "Intelligence Quotient" or IQ (Intelligence Quotient). It is calculated by the formula:

100 x (intellectual age/biological age).

So, if you are 30 years old, but your IQ is 25 years old, your IQ would be: 100 x 25/30 = 83.

Distribution of IQ among the population (on the vertical axis - % of the population with iq indicated on the horizontal axis

It is clear that according to this method, the average IQ for the entire population will be 100. The individual IQ of a person shows how much a person is above or below the average intellectual level of his age.

Thus, to conduct tests, statistics are first collected on the performance of these tests on a large number of people. Then the performance of each newly tested person is compared with the average performance of people who have previously passed the tests.

Since in the classical version of the tests, the results are compared with the same audience as that of the test subject by age, IQ also indicates the rate of development of intelligence.

Intelligence tests are designed to test all areas of your brain: computation, pattern recognition, sequence continuation, logic, word processing, abstraction, and so on. The result obtained is compared with the norm.

There are various interpretations of the obtained results.

80% of the population has an IQ in the 80-120 range.

There are quite a few high IQ communities around the world. For example, Mensa, which has members from over 100 countries, requires an IQ of at least 132 for its members.

In order to get into the Olympic Society (Olympiq Society) you need an IQ of 180. The community website indicates that it has only 14 members.

It is believed that the results of IQ tests are good at determining the ability of people, and are good predictors of their prospects for difficult work. Most professors have an IQ of one hundred and thirty, which puts them in the top 3% of the population in terms of intellectual ability.

Although IQ tests are not infallible, their results are a useful indicator. As a rule, the IQ indicator remains unchanged throughout life.

Interestingly, a study in Scotland in the 1950s and 1960s of more than 11,000 people showed a relationship between IQ scores and morbidity, as well as life expectancy.

A pattern has been revealed that a person with a lower IQ has an average life expectancy lower than a person with a higher IQ.

A lower IQ means a higher chance of developing Alzheimer's and other forms of dementia.

What was Einstein's iq?

Albert Einstein never took a test to change the level of his IQ. Of course, there is no doubt that the famous physicist could show a high result. Most likely it would be in the region of 200, that is, at the level of the best achievements of celebrities.

People have different skills and levels of intelligence: verbal, typical, spatial, conceptual, mathematical

The researchers found that high IQ can really help people in many areas of life, but it does not guarantee success in life.

So there is no need to worry about the lack of genius, since the vast majority of people are not geniuses. Just as a high IQ does not guarantee success, an average or low IQ does not guarantee failure or mediocrity. Other factors such as hard work, resilience, perseverance and general attitude are important pieces of the puzzle. published

Many of us have heard of the IQ test, which measures a person's level of intelligence. However, most people know almost nothing about it. Before you start taking the test, you must definitely find out what IQ should be 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 well-established expression "intelligence quotient" is more often used. However, it is believed that in order for the results to be as truthful as possible, and they can really be trusted, it is worth taking into account not only the results of the test itself. Factors such as age and gender also need to be taken into account.

Many also believe that the results of this test indicate a person's aptitude for a particular type of task rather than actual intellectual ability. Therefore, you can prepare for it by solving puzzles that resemble those presented in the tasks.

Story

Attempts to study the IQ of a normal person began in the 30s of the last century. Researchers have made a number of attempts to determine the IQ 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 took into account the size and weight of the brain. In addition, they studied the relationship between the IQ of parents and children, its relation to social origin, age, and so on.

IQ test today

It is now 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 problems and tests. Besides, in modern world it is not so much intelligence that is the source of success as motivation and perseverance. Important role individuality, determination and ambition also play. 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 wide variety of tasks. Among which are counting exercises, logical series, the ability to find the 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 correctly solved problems. The person who completes all the tasks receives 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. By identifying the category in which the subject has the lowest level of ability, you can help him identify gaps in his ability, train with different types tasks and raise the coefficient of intelligence.

First tests

For the first time, V. Stern spoke about the IQ, who considered the determination of the level of skills on the Binet scale to be incorrect, since he had a serious drawback regarding age. The scientist proposed to determine a person's abilities by dividing mental age by chronological age. The IQ test of a normal person demonstrates a quantitative assessment of the ability of an individual in relation to the average representative of the same age.

Averages

It is rightfully considered that an IQ test does not show the level of a person's erudition, but only an assessment overall indicators. They are designed specifically to get a distribution of results with an average score. The IQ of a normal person can vary, but there are common 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 score for American college graduates is 115, with honors ranging from 135 to 140. An IQ that is less than 70 is generally considered a sign of mental retardation.

Conclusion

IQ tests show the level of development of a person's abilities, but should not be considered that they in any way indicate the level of erudition. They only help to understand in what area and in what 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 IQ. However, do not forget that the most correct results will be obtained during the very first passing of the test, and all subsequent attempts will only distort them.

Human IQ is a measurable assessment of human intelligence, expressed in points. The IQ varies from person to person, so it’s worth figuring out what level can be considered normal.

Age

It has been statistically proven that IQ changes with age. It reaches its peak at the age of 25. It is generally accepted in the world that an IQ of 100 points is average. IQ of a five year old

reaches 50-75 points, at 10 years old it ranges from 70 to 80 points, at 15-20 years old it can reach the average value for an adult of 100 points. In many countries of the world (for example, the USA and Japan), gifted people are selected based on IQ tests.

And then they

pass

training on the strengthened and accelerated system. This is due to the fact that children with an IQ increased for their age, as a rule, learn much better and faster than their peers.

Race

Strange as it may sound, but IQ varies from race to race. For example, the median IQ for African Americans is 86, for whites of European descent it is 103, and for Jews it is 113. All this speaks in favor of the supporters of scientific racism. However, this gap is narrowing from year to year.

Floor

Women and men do not differ from each other in intelligence, but, according to statistics, the IQ between them differs depending on age. Boys under the age of 5 years are somewhat smarter than their peers, but, starting from the age of 10-12 years, girls are ahead of boys in development. This gap disappears by the age of 18-20.

Normal IQ

The intelligence quotient of an adult depends on many factors - genetics, upbringing, Environment, race, etc. Although the average IQ is about 100 points, it varies from 80 points to 180. This IQ limit is laid down in the classic IQ test, developed by the English psychologist Hans Eysenck in 1994. In order to obtain adequate data on this test, it must be passed once in a lifetime in adulthood. Repeated passage distorts and overestimates the results.

If the IQ is below 80 points, then this indicates the physical and mental deviations of a person. If IQ exceeds 180 points, then this indicates the genius of the owner of such points. But these dependencies are very conditional. For example, the great physicist Albert Einstein was the most backward in the class in terms of academic performance, which did not prevent him from developing the theory of relativity in the future. And on the other hand, according to the Guinness Book of Records, the largest IQ of 228 points was recorded in 1989 by ten-year-old American Marilyn Waugh Sawan. This is where her personal achievements end.
