Rating scales were used to identify characteristic aphasic phenomena in a sample of natural language from aphasic patients. These variables were used to derive empirically four groups of aphasic patients. These groups showed significant multivariate differences on the basis of their performance on the Neurosensory Center Comprehensive Examination for Aphasia. Seven subtests showed significant univariate differences among the four groups: Visual Naming, Description of Use, Sentence Repetition, Repetition of Digits, Reversal of Digits, Identification by Sentence, and Oral Reading Sentences. Two of the groups reflected Howes dichotomy of articulate-nonarticulate language disorders. Another group was thought to reflect Schuell's single dimension of language disorders that could be differentiated only in terms of severity. Afourth group was characterized by a major impairment of memory. These results indicated that aphasic phenomena could be identified reliably on the basis of rating of verbal output on scales that reflect language disorders. These scales were used in a statistical fashion to derive empirically oriented groups that were identified on the basis of psychometric measures of language skills.
使用评定量表从失语症患者的自然语言样本中识别特征性失语现象。这些变量被用于从经验上划分出四组失语症患者。这些组在失语症神经感觉中心综合检查中的表现显示出显著的多变量差异。七个分测验在四组之间显示出显著的单变量差异：视觉命名、用途描述、句子复述、数字复述、数字倒背、句子识别和朗读句子。其中两组反映了豪斯关于清晰性-非清晰性语言障碍的二分法。另一组被认为反映了舒尔语言障碍的单一维度，只能根据严重程度进行区分。第四组的特征是记忆严重受损。这些结果表明，基于反映语言障碍的量表对言语输出进行评分，可以可靠地识别失语现象。这些量表以统计方式使用，以得出基于语言技能心理测量指标确定的、具有经验导向的组。
