Who coined the term ‘mental age’?
Answer: B
Alfred Binet introduced the idea of mental age in the Binet-Simon scale to compare a child's performance with the typical performance of children of different ages. Terman revised the scale and used the intelligence quotient, Wechsler developed deviation IQ, and Cattell used the term mental test. Binet and Simon published the first intelligence scale in 1905 to identify children who needed special help in school, and the idea of mental age was used there to describe a child's level of performance in terms of the age at which an average child could do the same tasks.
