Mary Whiton Calkins

Died 26 Feb 1930 at age 66 (born 30 Mar 1863).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.
