French psychologist Alfred Binet (1859-1911) took a different approach from most other psychologists of his day: He was interested in the workings of the 26 mind rather than the nature of mental illness. He wanted to find a way to measure the ability to think and reason, apart from education in any particular field. In 1905 he developed a test in which he 27 children do tasks such as follow commands, copy patterns, name objects, and put things in order or arrange them properly. He later created a standard of measuring children’s intelligence 28 the data he had collected from the French children he studied. If 70 percent of 8-year-olds could pass a particular test, then 29 on the test represented an 8-year-old’s level of intelligence. From Binet’s work, the phrase “intelligence quotient” (“IQ”) entered the English vocabulary. The IQ is the ratio of “mental age” to chronological age times 100, with 100 30 the average. So, an 8-year-old who passes the 10-year-old’s test would have an IQ of 10/8 times 100, or 125.
