When people’s intelligence is discussed, one term is often used – IQ . IQ is considered synonymous with intelligence. Today this IQ is the subject of our article. By the end of this article you will know what is IQ , what is IQ full form, how did it originate and how is it calculated?
You must have often heard people saying that his IQ level is very high or his IQ is weak. So much everyone knows that this is a word related to intelligence, but only a few people know the full form of IQ . Maybe you too will be one of them. Anyway, leave it. Today’s article of ours will solve all your problems because today I will tell you the full form of IQ ( IQ full form ), what is IQ, History of IQ etc.
IQ full form: What is the full form of IQ?
Let us first know the full form of IQ .
The full form of IQ in English is – Intelligence Quotient .
The full form of IQ is – Intelligence Quotient .
What is IQ?
IQ is a standard score that shows how mentally capable a person is in comparison to their peer group. IQ is a score that measures a person’s intelligence.
The IQ test assesses various types of cognitive skills and the score obtained from this test is used to test an individual’s intellectual ability and skills. The IQ test is the most popular psychological test.
How did the IQ test originate?
Sir Francis Galton wrote some articles on human intelligence in the late 1800s. Galton believed that humans inherited intelligence. He believed that a person’s response to sensory tasks reflected his intelligence.
James McKeen Cattell and other psychologists suggested that mental tests could be used to measure IQ . Celebrities such as Paul Broca and Wilhelm Wundt also expressed their views on human intelligence. Although the first accurate IQ test was made a few years later.
Alfred Binet (1857–1911) and Theodor Simon (1873–1961) developed the first modern IQ test in 1904. It was also known as Simon-Binet IQ test .
In France, it was legal for all children to attend school. It was important to find a method to identify children who might need additional support. The French Ministry of Education tasked these researchers with inventing a testing technique to differentiate between children who are gifted but indolent, and those who are mentally handicapped.
The scores obtained from this test were combined with the age of the child to determine whether the child was intellectually faster than other children of the same age. This test was very successful in Europe and the United States.
But this technique also had some disadvantages of its own. Let us know what they were.
What were the limitations of the Simon-Binet IQ test?
Binet believed that his psychometric instruments were unique, immutable and could not measure innate intelligence. He argued that intelligence is a belief that cannot be measured by a number alone. According to Binet, intelligence is a very complex concept because it is influenced by a variety of things, develops over time, and can only be compared in children with similar circumstances.
The Binet–Simon IQ test provided only a partial assessment of intelligence because it did not always take this complexity into account. Some psychologists have developed new, more in-depth intelligence testing techniques to provide better results.
Now we will discuss a similar test technique which was slightly better than the Binet-Simon IQ test.
Stanford-Binet Scale: Stanford-Binet Scale
Stanford University psychologist Lewis Terman enlisted the help of some American volunteers to make changes to Binet’s original test. As a result, a new test technique was invented which was a modified version of the Binet–Simon test. It was named the Stanford-Binet Intelligence Scale or the Stanford-Binet Scale. The development of this test took place in 1916.
The Stanford-Binet test measures human intelligence by means of only one number. This number is called IQ . Despite undergoing many changes, this testing technique is still considered as the most popular intelligence assessment technique today. A person’s IQ is calculated by dividing their mental age by their chronological age, then multiplying this number by 100.
Suppose, the mental age of a child is 15 years and his chronological age is 10 years. Then his IQ becomes (15/10)x100 = 150.
Wechsler Intelligence Scale: Wechsler Intelligence Scale:
David Wechsler, another psychologist like Lewis Terman, invented a technique in 1955 that involved calculating intelligence based on various mental abilities.
He believed that his technique was better than the Stanford-Binet test. Two testing techniques were developed for children called the Wechsler Intelligence Scale (WISC) and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). As for children, adult versions of these techniques were also available which underwent several modifications and is now known as WAIS-IV.
The WAIS-IV score is determined by comparing the test taker’s score with the scores of other test takers of the same age. The average score is set at 100. Two-thirds of the scores fall within the normal range, which is between 85 and 115. This method of scoring has become accepted in intelligence tests, and is also employed in the current Stanford-Binet test version.
Why is an IQ test useful? Why is IQ test useful?
- IQ tests are sometimes used in the criminal justice system to determine whether a person will be able to defend himself or herself during a trial.
- IQ testing can help detect learning problems.
- Artificial Intelligence (AI) in computers uses the same principles as for testing IQ on humans.
- IQ is likely to predict mental illness.
- Sometimes, IQ tests are used to assess the effectiveness of therapy or the effect of medical treatment on cognitive function.
