[First rank symptoms of schizophrenia (Kurt Schneider): Are they still of any importance? (author's transl)].

The general importance of paying attention to symptomatology in psychiatry is stressed. Research in this area has been advanced by modern psychopathometric methods. A renewal of general interest in the "classical" symptomatology of the older German authors is also shown by research involving Kurt Schneider's first rank symptoms of schizophrenia in England and the USA. Important papers concerned with this latter trend are discussed.
