Calkins was part of the controversy that arose over John Watson’s now famous Psychological Bulletin article published in 1913, “Psychology as the Behaviorist Views It.” In the article he argued that introspection forms no part of scientific psychology. Calkins was opposed to the wholesale elimination of introspection as a psychological method, and remained certain that some psychological processes could be studied only by introspection. She pointed out that introspection is itself a method for studying behavior, especially complex behavior such as that of imagining, judging, and reasoning. However, she was sympathetic to Watson's observation that psychology had become too far removed from the problems of everyday life. All in all, Mary Whiton Calkins was a remarkable scientist, scholar, APA President, and human being.
