The third edition of the Stanford-Binet Intelligence Scale by Lewis M. Terman and Maud A. Merrill was published in 1972. It is a wide-range individual test, assessing intelligence from age two through the superior adult level. It is an age scale, requiring subjects to solve problems, give definitions, memorize new material, and use some visual-motor skills at various age levels.
Lewis Madison Terman was an American psychologist and author. He was noted as a pioneer in educational psychology in the early 20th century at the Stanford Graduate School of Education. He is best known for his revision of the Stanford–Binet Intelligence Scales and for initiating the longitudinal study of children with high IQs called the Genetic Studies of Genius. He was a prominent eugenicist and was a member of the Human Betterment Foundation. He also served as president of the American Psychological Association. A Review of General Psychology survey, published in 2002, ranked Terman as the 72nd most cited psychologist of the 20th century, in a tie with G. Stanley Hall.
