These experiments yielded examples of writing that appeared to represent "stream of consciousness", a psychological theory often attributed to James and the style of modernist authors Virginia Woolf and James Joyce. In 1934, behavioral psychologist B.F. Skinner interpreted Stein's difficult poem "Tender Buttons" as an example of "normal motor automatism". In a letter Stein wrote during the 1930s, she explained that she never accepted the theory of automatic writing: "here can be automatic movements, but not automatic writing. Writing for the normal person is too complicated an activity to be indulged in automatically." She did publish an article in a psychological journal on "spontaneous automatic writing" while at Radcliffe, but "the unconscious and the intuition (even when James himself wrote about them) never concerned her".
