BINET, ALFRED (1857-1911)
…
Binet is best known to psychologists for initiating the modern approach to intelligence testing
…
As a rule of thumb (but with the proviso that test results should never be the sole criterion for diagnosing subnormality), Binet suggested that children whose mental ages lagged more than 2 years behind their actual ages should be targeted for further investigation. Implicit here was the notion that mental deficiency in children can be conceptualized as a retardation in the normal rate of intellectual development.
…
In due course Binet himself conceded that his hypnotic experiments had been fatally tainted by the effects of unintended suggestion, which he referred to as the “cholera of psychology.”
…
Binet’s 1900 book, La Suggestibilite, elaborated by demonstrating how sensitive children are to the style as well as the content of questions put to them. This work is now recognized as a pioneering and still valid warning about the potential unreliability of children’s eye-witness testimony
…
Furthermore, he firmly believed that the intelligence measured by his tests was not a fixed entity, but could be enhanced by appropriate training, which he called mental orthopedics.
…
The German psychologist Louis William Stern (1871-1938) proposed computing an “intelligence quotient” for each child by taking the ratio of mental age over chronological age, and the American Lewis M. Terman (1877-1956) multiplied Stern’s quotient by 100 and abbreviated the result as the now famous “IQ.”
