A single case study of a patient, ROH, who had a space occupying lesion in the left frontal lobe is reported. His selective speech disorder had all the hallmarks of a dynamic aphasia. Tests of sentence completion, phrase generation and sentence generation were administered. His ability to generate sentences was significantly better given a pictorial context than a verbal context. Although he could order a sequence of pictures, he had the greatest difficulty in ordering the constituent words of a sentence. Luria's hypothesis that dynamic aphasia is due to an impairment of inner speech which provides "the linear scheme of a sentence" is discussed. It is concluded that dynamic aphasia does not reflect a deficit of language processing but rather the selective impairment of verbal planning.
本文报告了一例名为ROH的患者的个案研究，该患者左额叶有占位性病变。他的选择性言语障碍具有动态失语症的所有特征。对其进行了句子完成、短语生成和句子生成测试。与言语语境相比，在图片语境下他生成句子的能力明显更好。虽然他能够对一系列图片进行排序，但在对句子的组成单词进行排序时却遇到了最大的困难。文中讨论了鲁利亚的假设，即动态失语症是由于内部言语受损所致，而内部言语提供了“句子的线性结构”。得出的结论是，动态失语症并不反映语言处理缺陷，而是言语计划的选择性受损。
