Abstract
In this descriptive study the verbal performance of four previously unmedicated schizophrenic subjects was evaluated prior to and two weeks following the effects of antipsychotic treatment … and compared to the performance of five continuously medicated schizophrenic subjects. Results obtained using two subtests of the Porch Index of Communicative Ability (PICA) and on the “Cookie Theft” picture description task from the Boston Aphasia Diagnostic Examination, revealed a variety of language disturbances that appeared to be related to medication status and classification of schizophrenia. Previously unmedicated subjects performed worse than medicated subjects on all tasks, however, disordered verbal performance was observed for all patients. Results are discussed in reference to a theory of hyperactivity of the cortical areas, and the influence of medication on performance.
