Woodworth, Robert Sessions, 1869-1962

Robert Sessions Woodworth (October 17, 1869 – July 4, 1962) was an American psychologist and the creator of the personality test which bears his name. A graduate of Harvard and Columbia, he studied under William James along with other prominent psychologists as Leta Stetter Hollingworth, James Rowland Angell, and Edward Thorndike. His textbook Psychology: A study of mental life, which appeared first in 1921, went through many editions and was the first introduction to psychology for generations of undergraduate students. His 1938 textbook of experimental psychology was scarcely less influential, especially in the 1954 second edition, written with Harold H. Schlosberg. Woodworth is known for introducing the Stimulus-Organism-Response (S-O-R) formula of behavior. He was elected to the American Academy of Arts and Sciences in 1935 and the American Philosophical Society in 1936. A Review of General Psychology survey, published in 2002, ranked Woodworth as the 88th most cited psychologist of the 20th century, tied with John Garcia, James J. Gibson, David Rumelhart, Louis Leon Thurstone, and Margaret Floy Washburn.
