One of the greatest of the methodological difficulties which the social sciences have had to face has been the discrepancy between verbalized behavior and behavior in life situations. The more fundamental and central a situation or relationship may be in family and marriage relationships for the individuals concerned, the greater is the social tension if such discrepancy arises. Psychodramatic procedure establishes a number of typical situations which are standardized for use in the various relationships which come under observation. These situations, of course, are based upon actual psychodramatic experience with many married couples. Psychodramatic treatment of marriage problems has emphasized the importance of the part played by hidden roles in the personalities of the two partners. Many cases of failure have been noted in which the cause could be traced to the emergence of the role, at a time which may be even years after the wedding.
