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".
本研究的主题是精神分裂症患者概念形成的障碍以及该障碍对交流的影响。对一组慢性精神分裂症患者及其正常对照者的颜色言语编码和识别进行了研究。在描述颜色时，精神分裂症患者表现出较低的变异性、较短的话语长度和较短的编码反应时间。这些症状被解释为表明精神分裂症患者没有意识到任务的复杂性，对不同描述之间的区分较少（过度包容）。这种较高的刻板性与所认为的精神分裂症患者较高的创造力相矛盾。在与正常人交流时，精神分裂症患者的编码与正常人的编码之间没有差异。然而，精神分裂症患者表现出解码缺陷。这也被解释为在“过度包容”概念意义内概念扩大的一个迹象。
