Terman, TUR muhn, Lewis Madison (1877-1956), was an American psychologist who became known for his studies of intelligence. In 1916, while teaching at Stanford University, Terman revised the Binet-Simon intelligence tests, which were in French, for English-speaking students. The revised examination, which is usually called the Stanford-Binet test, became one of the most widely used tests of learning ability. Terman worked with Maud A. Merrill, another Stanford psychologist, on revisions of the test that were published in 1937 and 1960.
