Alfred Binet

Binet studied law, graduating in 1878. He then studied medicine and biology at the Sorbonne , followed by research at the neurological laboratory of the Hôpital Salpêtrière under Jean-Martin Charcot from 1883 to 1889.

In 1889 he helped found the first psychological research laboratory in France. As a director, he tries to develop experimental methods for measuring intelligence and logical thinking skills. He also founded the first French journal for psychology, L'année psychologique (The Psychological Year), in which he published his research results.

He made one of the greatest achievements in the field of intelligence measurement. Together with the doctor Théodore Simon (1873–1961), he developed a test to measure a child's mental abilities. The test consisted of tasks that were intended to determine general intelligence and that were graded by age group. A number of points was calculated from the number of correctly solved tasks; this resulted in the child's “ intelligence age ”. This test was called the Binet-Simon test and was first used in 1905. The Stanford-Binet test was later developed by Lewis Madison Terman .

In his book Psychologie des grands calculateurs et joueurs d'échecs (Paris 1894) he dealt with memory processes , a. a. based on surveys of chess players , and thus founded chess psychology .

Binet died in Paris on October 18, 1911. His research results in the field of intelligence measurement are used by psychologists in many countries.
