A cluster analysis, based upon the naming errors of 61 non-selected aphasiacs, was performed. Three clusters emerged; the first was marked by phonemic errors, the second by semantic ones and the third by the use of escape mechanisms. Subjects in the second cluster were less impaired; this could be a consequence of the disturbance type involved. Though many patients of first and third groups displayed a Wernicke aphasia, whereas Broca aphasia predominated in the second one, a concordance of clusters with aphasiologic diagnoses was far from excellent.
基于61名未经挑选的失语症患者的命名错误进行了聚类分析。出现了三个聚类；第一个以音素错误为特征，第二个以语义错误为特征，第三个以逃避机制的使用为特征。第二个聚类中的受试者受损较轻；这可能是所涉及的障碍类型导致的结果。虽然第一组和第三组的许多患者表现为韦尼克失语症，而第二组中布罗卡失语症占主导，但聚类与失语症诊断的一致性远非完美。
