[Psychopathologic symptoms from the aspect of psycholinguistics]

The authors stress the importance of differentiated, detailed psychopathologic theory with use of differentiated psychopathological dictionary. With practical use it can not compete with simple scales, inclusion and exclusion criteria, with operational techniques. It has only limited use in research, which must respect scientific principles. But it can bring the scientists nearer to understanding of "what" is psychosis and "what" is neurosis, and so on: so it favours "what" to "how".
