Despite the long-standing interest in structural aspects of aphasic production, no method has emerged for the systematic analysis of aphasic speech. This paper attempts to address that need by outlining a procedure for the quantitative assessment of narrative speech which yields measures for both morphological and structural characteristics of aphasic production. In addition to complete instructions for carrying out this analysis, data for three groups of subjects are presented: agrammatic aphasics, aphasics who are similarly nonfluent but not clinically judged as agrammatic, and normal controls. While the agrammatics were distinguishable from the nonagrammatic patients on most measures, both nonfluent groups showed comparable reductions in the structural complexity of their propositional utterances. Other findings include indications from individual patient data that aspects of grammatical morphology may dissociate in agrammatism.
尽管长期以来人们对失语症语言表达的结构方面很感兴趣，但尚未出现用于系统分析失语症言语的方法。本文试图通过概述一种对叙述性言语进行定量评估的程序来满足这一需求，该程序能够得出失语症语言表达的形态学和结构特征的测量结果。除了进行此分析的完整说明外，还给出了三组受试者的数据：语法缺失型失语症患者、同样不流畅但临床判断并非语法缺失型的失语症患者以及正常对照组。虽然在大多数测量指标上语法缺失型患者与非语法缺失型患者有明显差异，但两个不流畅组在命题语句的结构复杂性上都有类似程度的降低。其他发现包括来自个体患者数据的迹象，表明语法形态学的某些方面在语法缺失症中可能会出现分离。
