本研究通过对136例住院男性精神分裂症患者的Halstead分类测验、触觉操作测验、连线测验的B部分和威斯康星州卡片分类测验的成绩进行聚类分析，探讨精神分裂症患者抽象能力和问题解决能力的异质性。广泛的异质性之间提取的五个集群，显着的表现水平和模式的差异。研究人员努力寻找集群成员与年龄、教育、一般智力、神经系统合并症和药物治疗状况之间的关联。在所有病例中均观察到此类相关性，但药物的作用被视为模棱两可。得出的结论是：（i）有广泛的异质性，在模式和水平的表现精神分裂症患者的测试抽象和解决问题的能力;和（ii）一些，但不是所有的这种异质性与年龄，教育，一般智力和神经共病的变化。
The study examines heterogeneity in abstraction and problem-solving abilities among schizophrenic patients through a cluster analysis of scores from the Halstead Category Test, the Tactual Performance Test, Part B of the Trail Making Test and the Wisconsin Card Sorting Test obtained from 136 male schizophrenic inpatients. Extensive heterogeneity was noted among the five clusters extracted, marked by differences in both level and pattern of performance. Efforts were made to find associations between cluster membership and age, education, general intelligence, neurological comorbidity, and medication status. Such associations were noted in all cases, but the role of medication was viewed as equivocal. It was concluded that (i) there is extensive heterogeneity in both pattern and level of performance of schizophrenics on tests of abstraction and problem solving; and (ii) Some, but not all of this heterogeneity is associated with variations in age, education, general intelligence, and neurological comorbidity.
