One psychiatrist's treatment of two paranoid schizophrenic patients is studied. Patients and therapist were asked to evaluate the relative importance of manifest issues introduced by the patients. Each patient and the therapist were then asked to rank their own ideas and to make predictions about the ranking of the others. At first, both patients' values were relatively distant from those of the therapist. However, after several months one patient's values changed and became significantly closer to those of the therapist. From this finding the authors emphasize the importance that the therapist become aware of his influence upon the patient's values. Similar research is being undertaken in regard to psychoanalysis.
