Written but not oral verbal production is preserved in young schizophrenic patients.
The aim of this study is to discover whether the language capabilities of young schizophrenic patients are more affected in speaking than in writing or whether the disorders are equivalent in the two modes. To do this, we compared spoken and written descriptions of pictures obtained from 10 schizophrenic patients with those produced by 10 control subjects. These productions were analysed on the basis of objective indices. The syntax and coherence of the productions were evaluated by judges. The comparison of the performances of the controls and schizophrenic patients supports the hypothesis that the latter suffer from a language disorder affecting the oral mode but impacting less frequently and less severely on the written mode. These results are discussed in the light of the cognitive mechanisms which may provide an explanation of these language disorders.
