LINGUISTIC IMPAIRMENT IN EARLY PSYCHOSIS

Twenty-four, first-admission, psychotic subjects and 24 control subjects were administered a linguistic instrument to elicit impairments in syntax, semantics, cohesion, and use of metaphors. In the same session, the subjects were also rated on the Scale for Thought, Language, and Communication Disorders (TLC). Results indicated a significant impairment of ail four linguistic categories in psychotic subjects. The impairment in semantics, however, was differentiated the most between the patient and control groups. The psychotic patients scored significantly higher on the TLC. Scores of impairment on the linguistic tasks did not correlate with scores on the TLC.
