ABSTRACT
From the domestic point of view the range of psycho-analysis is set by Freud's theory of a mental apparatus the functions of which are to receive, control, distribute and discharge excitation. Whoever accepts the concept of the Id is in a position to indicate the external frontiers of psycho-analysis. Moreover the concept of negative affects, loosely but inaccurately termed 'unconscious' or 'repressed' affects is without the scope of descriptive psychology. Some of the psycho-analytical types present problems that are difficult to assess except through individual analysis, and they must sometimes appear to the social psychologist as, to say the least of it, aggravating complications. The concern of social psychology lies in two main directions, charting the social manifestations, structure and function of groups, and tracing the influence of social factors on the psychology of the individual.
