Verbal behavior and schizophrenia. The semantic dimension.

Through the use of computer analysis, the content of the speech of schizophrenics is shown to be distinct from that of the speech of nonschizophrenic psychiatric patients. The data shed light on qualities that delineate some aspects of "bizarreness" in speech of schizophrenics, provide some insight into the diversity of postulated "defects" in schizophrenic thinking, and provide further understanding of the diagnostic process in schizophrenia.
