Under the term 'psychogenic cure', Oberndorf includes all psychotherapeutic procedures, from the magic of the primitive medicine man to psychoanalysis. All psychogenic cures have two main factors in common: the source (person, institution, shrine, analyst, etc.) and the timing of the suggestions or interpretations offered the patient. It is with the latter factor that Oberndorf principally concerns himself. As is well known, an interpretation made at one point during analysis does not 'take', whereas the identical interpretation made at another time falls on fertile ground and can be utilized to great advantage by the patient. This and other problems of analytic technique are discussed.
