What is IQ (Intelligence Quotient)?

IQ is an abbreviation for intelligent quotient and refers to the score for several standardized intelligence tests. The first was developed by French psychologist Alfred Binet in 1905. He built a IQ test, as he would later call himself to determine which children may need further help in scientific persecutions. Today, this test is usually based on an Intelligence Stanford Binet scale. In fact, this test measures mathematical and spatial thinking, logical abilities and language understanding. Thus, a person who speaks English as a second language could poorly score on the aspects of the test language and would not be a reasonable measurement of intelligence. So it's not a predictor of a person's quality or Worth, although it is sometimes used as such.

Some things may negatively affect the IQ score. These include malnutrition in children that are tested and fetal alcohol syndrome or mother -in -law. Mental retardation or conditions that worsen the ability toTo remember, such as Alzheimer's disease, also causes the score to be lower. IQ can also be influenced by a lack of appropriate education, often due to the difference in educational financing. If these differences are corrected, then it normally increases.

people can also train to perform IQ tests, which can increase scoring. However, it is not known whether a person who scores higher due to training or repeated testing is actually more intelligent. It is verifiable that a trained person is doing better on the test than a person who is not trained.

Some studies about the size and development and development of the brain have been held. Crankly, the frontal lobe of the brain seems to be the most indicative method to predict the score. Larger frontal lobes tend to result in larger IQ.

It seems that men and women scored approximately the same in IQ testing, although men show a larger scattering during testing and have more very muchHigh and very low scores than women. The American Psychological Association has conducted a study on IQ and came up with the following conclusions:

• IQ score was quite a good predictor for school performance.
• The score can also predict quite well to what extent the person can be successful in occupations.
• The score tends to show some racial bias.
• test scores can be influenced by personal genetic history.

6 There is also a debate about how much scores should be used as a predictor of behavior. Some may negatively affect the perception of universities, private schools or employers if they are used to determine employability or admission to schools.
