by Grace Helen Kent, A. J. (Aaron Joshua) Rosanoff
Born in Michigan City, Indiana, on June 6, 1875, Grace Helen Kent became an American psychologist whose research focused on mental testing and psychiatric diagnosis. She is best known for her work on the Kent-Rosanoff Free Association Test, a word-association method designed to help distinguish different patterns of thought in psychiatric patients.
Kent studied at the University of Iowa and later worked in hospital and research settings where psychology and psychiatry closely overlapped. Her best-known publication, A Study of Association in Insanity (1910), written with A. J. Rosanoff, examined how patients responded to carefully chosen stimulus words and helped establish free association as a useful clinical tool.
She also worked at Worcester State Hospital, where she contributed to psychological assessment more broadly, including research connected to form-board testing. Kent died on September 18, 1973, in Sandy Spring, Maryland, leaving behind a body of work that reflects the early development of clinical psychology in the United States.
