The authors are bent on showing a relationship between the repression of aggression and a spastic colon. For this purpose they used the Schneider Test, Turner Prolonged Standing Test and the Cold Pressor Test as well as some form of psychiatric investigation. Their psychiatric concepts seem to be a conglomeration of Adler, Jung, and Meyer, with a sprinkling of Freud. This article also includes many superficial case histories and a graph of libidinal oscillations.
