• A technique was devised to elicit bizarre or idiosyncratic responses from 30 young schizophrenics, who were then reinterviewed a week later to determine the reasons for each patient's idiosyncratic verbalizations. Taped interviews of the schizophrenics, scored along a series of rating scales, indicated: (1) An overt mechanism involved in bizarre schizophrenic language is a tendency to intermingle into their responses material from their current and past experiences. (2) Careful analysis suggests that the seemingly bizarre intermingled material of schizophrenics usually is close to the original "correct" topic. (3) The bizarre intermingled material is related to the patients' personal lives. (4) The intermingled material does not usually represent a failure to screen out or repress primitive drive dominated sexual or aggressive material. (5) Disordered logic was not a major factor in accounting for bizarre schizophrenic language.
