IQ Classification
IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient (IQ) tests, into categories such as "superior" and "average". In the current IQ scoring method, an IQ score of 100 means that the test-taker's performance on the test is of average performance in the sample of test-takers of about the same age as was used to norm the test. An IQ score of 115 means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. This "deviation IQ" method is now used for standard scoring of all IQ tests in large part because they allow a consistent definition of IQ for both children and adults. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to 115, and about 5 percent of the population scores above 125 (''i.e.'' Normal distribution#Standard deviation and coverage, normal distribution).

Army Alpha
The Army Alpha is a group-administered test developed by Robert Yerkes and six others in order to evaluate the many U.S. military recruits during World War I. It was first introduced in 1917 due to a demand for a systematic method of evaluating the intellectual and emotional functioning of soldiers. The test measured "verbal ability, numerical ability, ability to follow directions, and knowledge of information". Scores on the Army Alpha were used to determine a soldier's capability of serving, his job classification, and his potential for a leadership position. Soldiers who were illiterate or foreign speaking would take the Army Beta, the nonverbal equivalent of the exam. Army Beta The development of the beta test and of the performance test for the examination of the foreign speaking and illiterate presented special problems. The use of demonstration charts and mime to convey the instructions to the persons being examined proved successful. The new type of the test in t ...

Supreme Court Of The United States
The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all Federal tribunals in the United States, U.S. federal court cases, and over State court (United States), state court cases that turn on questions of Constitution of the United States, U.S. constitutional or Law of the United States, federal law.

Wechsler Adult Intelligence Scale
The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. For children between the ages of 6 and 16, Wechsler Intelligence Scale for Children (WISC) is commonly used. The original WAIS (Form I) was published in February 1955 by David Wechsler, Chief Psychologist at Bellevue Hospital (1932–1967) in NYC, as a revision of the Wechsler–Bellevue Intelligence Scale released in 1939. It is currently in its fifth edition (''WAIS-5''), released in 2024 by Pearson. It is the most widely used IQ test, for both adults and older adolescents, in the world. History The WAIS was founded to get to know Wechsler's patients at Bellevue Hospital and on his definition of intelligence, which he defined as "... the global capacity of a person to act purposefully, to think rationally, and to deal effectively with his environment." He believed that intelligence was made up of specific elements that could b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Stern (psychologist)
Louis William Stern (born Ludwig Wilhelm Stern; April 29, 1871 – March 27, 1938) was a German American psychologist and philosopher who originated personalistic psychology, which placed emphasis on the individual by examining measurable personality traits as well as the interaction of those traits within each person to create the self. Stern coined the term intelligence quotient (IQ) and invented the tone variator as a new way to study human perception of sound. Stern studied psychology and philosophy under Hermann Ebbinghaus at the Humboldt University of Berlin, and quickly moved on to teach at the University of Breslau. Later he was appointed to the position of professor at the University of Hamburg. Over the course of his career, Stern authored many books pioneering fields of psychology such as differential psychology, critical personalism, forensic psychology, and intelligence testing. Stern was also a pioneer in the field of Developmental psychology, child psychology. Toget ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Spearman
Charles Edward Spearman, FRS (10 September 1863 – 17 September 1945) was an English psychologist known for work in statistics, as a pioneer of factor analysis, and for Spearman's rank correlation coefficient. He also did seminal work on models for human intelligence, including his theory that disparate cognitive test scores reflect a single general intelligence factor and coining the term ''g'' factor. Biography Spearman had an unusual background for a psychologist. In his childhood he was ambitious to follow an academic career. But first he joined the army as a regular officer of engineers in August 1883, and was promoted to captain on 8 July 1893, serving in the Munster Fusiliers. After 15 years he resigned in 1897 to study for a PhD in experimental psychology. In Britain, psychology was generally seen as a branch of philosophy and Spearman chose to study in Leipzig under Wilhelm Wundt, because it was a centre of the "new psychology"—one that used the scientific met ...

G Factor (psychometrics)
The ''g'' factor is a construct developed in psychometric investigations of Cognitive skill, cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The ''g'' factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores ("IQ scores") based on many tests are frequently regarded as estimates of individuals' standing on the ''g'' factor.Kamphaus et al. 2005 The terms ''Intelligence quotient, IQ, general intelligence, general cognitive ability, general mental ability'', and simply ''intelligence'' are often used interchangeably to refer to this common core shared by cognitive tests.Deary et al. 2010 However, the ''g'' factor itself is a mathematical constr ...

Alfred Binet
Alfred Binet (; ; 8 July 1857 – 18 October 1911), born Alfredo Binetti, was a French psychologist who together with Théodore Simon invented the first practical intelligence test, the Binet–Simon test. In 1904, Binet took part in a commission set up by the French Ministry of Education to decide whether school children with learning difficulties should be sent to a special boarding school attached to a lunatic asylum, as advocated by the French psychiatrist and politician Désiré-Magloire Bourneville, or whether they should be educated in classes attached to regular schools as advocated by the Société libre pour l'étude psychologique de l'enfant (SLEPE) of which Binet was a member. There was also debate over who should decide whether a child was capable enough for regular education. Bourneville argued that a psychiatrist should do this based on a medical examination. Binet and Simon wanted this to be based on objective evidence. This was the beginning of the IQ test. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
