英语词汇binet-simon tests的起源、历史背景-英语词源词典

Binet-Simon tests. The first intelligence tests were developed by Alfred Binet (1857–1911), a French psychologist who di- rected the laboratory of psychology and physiology at the Sorbonne, in conjunction with psychologist Theodore Simon. The initial tests, later extended in age, determined the intelli- gence quotient of children three to 12, each subject being asked questions adapted to the intelligence of a normal child of his age. The Binet-Simon tests have been revised many times since their invention in 1905. Intelligence quotient, or I.Q., on such tests is merely a ratio, expressed as a percentage, of a person’s mental age to his actual age, his mental age being the age for which he scores 100 percent on all the questions. The score 150 is generally accepted as genius and below 70 is classified as mental deficiency.
