Argelander discerns the first recorded "walk-in interview" in Freud's case "Katharina…" which appeared in Studies on Hysteria. By secondary analysis he traces how Freud succeeded in uncovering the incident which had triggered the patient's hysterical symptoms—namely, in the framework of an interview situation which permitted a partial scenic reproduction of that very incident. Argelander's main interest is in the conditions that are favorable for the technique of evoking memories, which Freud applied here for the first time without any auxiliary means of suggestion.
