Münsterberg in his lab with a woman). After expressing her desire to work with Münsterberg to James, she learned from him that Münsterberg would soon be coming to work at Harvard. In the three years that Calkins studied under Münsterberg, several of her papers were published, including research she conducted with Sanford on dreams and her first paper on association. In her autobiography, she describes Münsterberg as "a man of deep learning, high originality, and astounding versatility." Other work with Münsterberg included their dream study. Hugo would begin by training her in the detail of laboratory experiments, giving her a research problem based on records that the two of them had taken of their dreams over several weeks. Over those weeks they would wake themselves with alarm clocks at different hours of the night, recorded their dreams, and then studied them intensely. The conclusion they reached was that dreams were nothing more than reproductions of "the persons, places, and events of recent sense perception." The discrimination she experienced due to her sex was also illustrated in earlier episodes. In her autobiography, Calkins reminisces on a date in which, as a member of the executive committee of the American Psychological Association, Munsterberg and his students, including Calkins, were to attend a lunch meeting of the Committee at the Harvard Union. The waiter there, though, protested the group's entrance stating that "no woman might set foot in the main hall; nor was it possible to admit so many men, balanced solely by one woman, to the ladies' dining-room." Although it seems like Calkins had a constant struggle as a female in her field, she expressed in her autobiography her gratitude for the individuals that did not discriminate against her. The "friendly, comradely, and refreshingly matter-of-fact welcome" that she received from the men working in Munsterberg's laboratory as assistants and students are described in her book with great appreciation. She also expressed her indebtedness to Munsterberg who "swung the Laboratory doors" open to her without hesitation. Doctoral research During this time, Calkins also studied memory, leading to her invention of the right associate's method, now known as the paired-associations technique. Calkins explains in her autobiography that "by showing series of colors paired with numerals, I found that a numeral which has repeatedly appeared in conjunction with a given color was more likely than either a vividly colored numeral or than the numeral last
