- Binet-Simon-Norden-Bobertag intelligence test
Intelligence test used particularly on children aged 3 to 15 years.
In the period from 1905 to 1908 the French psychologists Alfred Binet and Théodore Simon devised a series of tests whereby the intellectual capacity of the subject is estimated by comparison with that of normal children and adolescents of various ages. The mental age divided by the chronological age gives the so-called IQ, or intelligence quotient. Their formula stated that children under nine whose development is retarded by two years are probably mentally deficient and that children of nine or more who are retarded by three years are definitely deficient.
Alfred Binet explicitly defined intelligence as “the components of intelligence are reasoning, judgement, memory, and the power of abstraction.” He measured intelligence as “general mental ability of individuals in intelligent behaviours.” He described intelligence testing as classifying, not measuring.
