Mary Whiton Calkins

Born 30 Mar 1863; died 26 Feb 1930 at age 66.American educator and psychologist who was the first american woman to attain distinction in these fields of study. Calkins studied psychology at Harvard as a “guest,” since women could not officially register. After completing all requirements for a doctorate at Harvard, and with the strong support of William James and her other professors, Harvard still refused to grant a degree to a woman. She established the first psychology laboratory at a women's college (Wellesley). She developed the paired-associate procedure for studying verbal memories. One of her main findings was that repeated pairings of words increased memory. Calkins was interested in a wide variety of research topics, including perception, personality, emotion, and dreaming.
