[Studies of incest].

Theories of the genesis of incest tabus are presented and possible causes of a high degree of latent incest criminality are discussed. On the basis of the evaluation of 32 forensic-psychiatric expertises, characteristics of the committers and criminogenic conditions of the delict are discussed. The author arrives at the opinion that there is no determined type of incestuous delinquents. Decisive causes of later incest criminality will certainly be found in insufficiently introjected value norms within emotionally disturbed parental families and in the mainly primarily disturbed families of the delinquent.
