Distractibility among paranoid and non-paranoid schizophrenics using subtests matched for discriminating power.

The performance of hospitalized schizophrenics broken down into paranoid and non-paranoid subgroups was compared with that of two control groups on an auditory distraction test designed to rule out the confounding effect of differences between the distraction and non-distraction subtests in discriminating power. The results supported the hypothesis of schizophrenic distractibility.
