註釋The purpose of the present investigation was to investigate the relationship between the deficit displayed on a distraction test and the occurrence of certain disturbances in the language behavior of paranoid and nonparanoid schizophrenic subjects. Distractibility was assessed using an auditory digit-span test performed with and without distraction. Speech samples were collected from each subject and judges were trained to rate the samples on specific characteristics. Paranoid and nonparanoid subjects were significantly more distractible than normal and nonschizophrenic psychiatric subjects. The analysis of the speech samples revealed that nonparanoid subjects displayed the most pervasive language disturbance. In the nonparanoid subgroup there was a significant positive correlation between distractibility and the incidence of the repetition of words. In the paranoid subgroup increases in distractibility were significantly associated with a lower incidence of repetitions. These results suggested that whereas nonparanoid subjects experienced interference with their speech plans, distractible paranoid subjects appeared capable of controlling the occurrence of certain interference effects while speaking.
