Alfred Binet (French:; 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. [2]
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
The test had become a scale, and the subtests were arranged from easiest to most difficult. The test also showed in detail the four to eight tasks that children should be able to perform at 11 different ages, ranging from 3 to 13. [3] [5] The test was constructed by giving the subtests to children of a specific (chronological) age group. If 75% ...
The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests yielding scaled scores that sum to derive the Full Scale IQ. With the WAIS-IV, the verbal/performance IQ scores from previous versions were removed and replaced by the index scores.
One early approach to measuring intelligence was the test developed in France by Alfred Binet and Theodore Simon. That test was known as the Test Binet-Simon .The French test was adapted for use in the U. S. by Lewis Terman of Stanford University, and named the Stanford-Binet IQ test.
Cognitive tests are assessments of the cognitive capabilities of humans and other animals.Tests administered to humans include various forms of IQ tests; those administered to animals include the mirror test (a test of visual self-awareness) and the T maze test (which tests learning ability).

In 1916 Binet's test was translated into English and revised by Lewis Terman (who introduced IQ scoring for the test results) and published under the name Stanford–Binet Intelligence Scales. Terman wrote that Mexican-Americans, African-Americans, and Native Americans have a mental "dullness [that] seems to be racial, or at least inherent in ...
