[Disorders of language and cognition in schizophrenic patients and their effect on communication].
The subjects of this study are disturbances of concept formation in schizophrenics and the influence of that disorder on communication. The verbal coding and recognition of colours of a group of chronic schizophrenics and their normal controls were investigated. In describing the colours, the schizophrenics showed less variability, lower utterance lengths, and shorter reaction times for coding. These symptoms were interpreted as an indication that the schizophrenics don't realize the complexity of the task and differentiate less between the different descriptions (over inclusion). This higher stereotypy contradicts the suggested higher creativity of schizophrenics. No difference was found between the coding of schizophrenics and that of normals in communication with normals. However the schizophrenics showed a deficit of decoding. This was also interpreted as an indication of enlarged concepts within the meaning of the conception of "over inclusion".
