Besides her experimental work, she read widely and drew on French and German experiments of higher mental processes stating they were intertwined with tentative physical movements. She viewed consciousness as an epiphenomenon of excitation and inhibition of motor discharge. She presented a complete "motor theory" in "Movement and Mental Imagery" (1916). During the 1920s she continued to amass experimental data from around the world to buttress her argument. She remained anchored in behaviorist tenets but continued to argue for the mind in this process. She took ideas from all major schools of thought in psychology, behaviorism, structuralism, functionalism, and Gestalt psychology, but rejected the more speculative theories of psychodynamics as being too ephemeral. In current psychology research, echoes of Washburn's insistence that behavior is part of thinking can be seen in dynamic systems approach that Thelen and Smith (1994) use to explain the development of cognition in humans.
