title: First rank symptoms of schizophrenia: questions concerning clinical boundaries.
abstract: The phenomenological criteria of prominent Anglo-American researchers on certain so-called passivity experiences, sense deceptions and delusional phenomena, reflecting their interpretations of Kurt Schneider's first rank symptoms of schizophrenia, are  examined. In this way the frequent discrepancies and difficulties in deliminiting the clinical boundaries of these phenomena more clearly come to light.
