LINGUISTIC REFERENCE PERFORMANCE IN PARENTS OF SCHIZOPHRENIC-PATIENTS

CLINICIANS have often reported observing subtle signs of thought disorder or communication difficulties in parents of schizophrenic patients. Ascertaining empirically whether these impressions are valid and, if so, clarifying the nature of such disturbances is important for at least two reasons. First, it could assist in elucidating the etiologies of the illness. If distinguishing parental characteristics could be clearly defined, then further research could be undertaken to determine to what extent they represent genetic vulnerability markers, pathogenic environmental influences, or behavioral responses to having a disordered offspring. Secondly, it could facilitate our understanding of the cognitive processes involved in schizophrenia or in the constitutional vulnerability to schizophrenia.
