Intelligence quotient Wikipedia. An intelligence quotient IQ is a total score derived from several standardized tests designed to assess human intelligence. The abbreviation IQ was coined by the psychologist. William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1. Historically, IQ is a score obtained by dividing a persons mental age score, obtained by administering an intelligence test, by the persons chronological age, both expressed in terms of years and months. The resulting fraction is multiplied by 1. IQ score. 2 When current IQ tests were developed, the median raw score of the norming sample is defined as IQ 1. SD up or down are defined as 1. IQ points greater or less,3 although this was not always so historically. By this definition, approximately two thirds of the population scores are between IQ 8. IQ 1. 15. About 2. Scores from intelligence tests are estimates of intelligence because concrete measurements e. IQ scores have been shown to be associated with such factors as morbidity and mortality,78 parental social status,9 and, to a substantial degree, biological parental IQ. While the heritability of IQ has been investigated for nearly a century, there is still debate about the significance of heritability estimates1. IQ scores are used for educational placement, assessment of intellectual disability, and evaluating job applicants. Even when students improve their scores on standardized tests, they do not always improve their cognitive abilities, such as memory, attention and speed. In research contexts they have been studied as predictors of job performance, and income. They are also used to study distributions of psychometric intelligence in populations and the correlations between it and other variables.

Flynn effect. Investigation of different patterns of increases in subtest scores can also inform current research on human intelligence. HistoryeditPrecursors to IQ testingeditHistorically, even before IQ tests were invented, there were attempts to classify people into intelligence categories by observing their behavior in daily life. Those other forms of behavioral observation are still important for validating classifications based primarily on IQ test scores. Both intelligence classification by observation of behavior outside the testing room and classification by IQ testing depend on the definition of intelligence used in a particular case and on the reliability and error of estimation in the classification procedure. The English statistician Francis Galton made the first attempt at creating a standardized test for rating a persons intelligence. A pioneer of psychometrics and the application of statistical methods to the study of human diversity and the study of inheritance of human traits, he believed that intelligence was largely a product of heredity by which he did not mean genes, although he did develop several pre Mendelian theories of particulate inheritance.

He hypothesized that there should exist a correlation between intelligence and other observable traits such as reflexes, muscle grip, and head size. He set up the first mental testing centre in the world in 1. Inquiries into Human Faculty and Its Development in 1. After gathering data on a variety of physical variables, he was unable to show any such correlation, and he eventually abandoned this research. French psychologist Alfred Binet, together with Victor Henri and Thodore Simon had more success in 1. Binet Simon test, which focused on verbal abilities. It was intended to identify mental retardation in school children,2. The score on the Binet Simon scale would reveal the childs mental age. For example, a six year old child who passed all the tasks usually passed by six year oldsbut nothing beyondwould have a mental age that matched his chronological age, 6. Fancher, 1. 98. 5. Binet thought that intelligence was multifaceted, but came under the control of practical judgment. In Binets view, there were limitations with the scale and he stressed what he saw as the remarkable diversity of intelligence and the subsequent need to study it using qualitative, as opposed to quantitative, measures White, 2. American psychologist Henry H. Goddard published a translation of it in 1. American psychologist Lewis Terman at Stanford University revised the Binet Simon scale, which resulted in the Stanford Binet Intelligence Scales 1.

General factor geditThe many different kinds of IQ tests include a wide variety of item content. Some test items are visual, while many are verbal. Test items vary from being based on abstract reasoning problems to concentrating on arithmetic, vocabulary, or general knowledge. The British psychologist Charles Spearman in 1. He observed that childrens school grades across seemingly unrelated school subjects were positively correlated, and reasoned that these correlations reflected the influence of an underlying general mental ability that entered into performance on all kinds of mental tests. He suggested that all mental performance could be conceptualized in terms of a single general ability factor and a large number of narrow task specific ability factors. Game Who Want To Be A Millionaire Bahasa Indonesia Pc there. Spearman named it g for general factor and labeled the specific factors or abilities for specific tasks s. In any collection of test items that make up an IQ test, the score that best measures g is the composite score that has the highest correlations with all the item scores.

Typically, the g loaded composite score of an IQ test battery appears to involve a common strength in abstract reasoning across the tests item content. Times New Roman All Caps Font. Therefore, Spearman and others have regarded g as closely related to the essence of human intelligence. Spearmans argument proposing a general factor of human intelligence is still accepted in principle by many psychometricians. Todays factor models of intelligence typically represent cognitive abilities as a three level hierarchy, where there are a large number of narrow factors at the bottom of the hierarchy, a handful of broad, more general factors at the intermediate level, and at the apex a single factor, referred to as the g factor, which represents the variance common to all cognitive tasks. However, this view is not universally accepted other factor analyses of the data, with different results, are possible. Some psychometricians regard g as a statistical artifact. United States military selection in World War IeditDuring World War I, a way was needed to evaluate and assign Army recruits to appropriate tasks. This led to the development of several mental tests by Robert Yerkes, who worked with major hereditarians of American psychometricsincluding Terman, Goddardto write the test. The testing generated controversy and much public debate in the United States. Nonverbal or performance tests were developed for those who could not speak English or were suspected of malingering. Based on Goddards translation of the Binet Simon test, the tests had an impact in screening men for officer training. At the start of the war, the army and national guard maintained nine thousand officers. Free Kindergarten Readiness Test Kinder.
