One generally experiences less trouble in the reproduction of pictures than thoughts. Hysterical patients who are usually visual are easier to manage than patients suffering from obsessions. Once the picture emerges from the memory we can hear the patient state that as he proceeds to describe it, it proportionately fades away and becomes indistinct; the patient wears it out, so to speak, by transforming, it into words. We then orient ourselves through the memory picture itself in order to find the direction towards which the work should be continued. We say to the patient, “Just look again at the picture, has it disappeared?”—“As a whole, yes, but I still see this detail.”—“Then this must have some meaning, you will either see something new, or this remnant will remind you of something.” When the work is finished the visual field becomes free again, and a new picture can be called forth; but at other times such a picture, in spite of its having been described, remains persistently before the inner eye of the patient, and I take this as a sign that he still has something important to tell me concerning its theme. As soon as this has been accomplished, the picture disappears like a wandering spirit returning to rest. It is naturally of great value for the progress of the analysis to carry our point with the patient, otherwise we have to depend on what he thinks is proper to impart. It, therefore, will be pleasant to hear that the pressure procedure never failed except in a single case which I shall discuss later, but which I can now characterize by the fact that there was a special motive for the resistance. To be sure, it may happen under certain conditions that the procedure may be applied without bringing anything to light; as, for example, we may ask for the further etiology of a symptom when the same has already been exhausted; or, we may investigate for the psychic genealogy of a symptom, perhaps a pain, which really was of somatic origin. In these cases the patient equally insists that nothing occurred to him, and he is right. We should strive to avoid doing an injustice to the patient by making it a general rule not to lose sight of his features while he calmly lies before us during the analysis. One can then learn to distinguish, without any difficulty, the psychic calm in the real non appearance of a reminiscence from the tension and emotional signs under which the patient labors in trying to disavow the emerging reminiscences for the purpose of defense. The differential diagnostic application of the pressure procedure is really based on such experiences.
