We investigated completion phenomenon for proverbs in cases demonstrating transcortical sensory aphasia due to a variety of diseases. Lack of this completion was exclusively observed in patients with focal atrophy. These patients showed a selective and consistent impairment in word comprehension without phonemic cue effects in naming. The completion phenomenon was present in patients demonstrating transcortical sensory aphasia due to other cerebral diseases. In these patients, comprehension deficits were not selective for words, or words not comprehended were inconsistent and some phonemic cue effects were observed. In a previous study, we reported that completion phenomena for multiplication tables, serial numbers and names of days were frequently noted in patients with focal atrophy. Together with the present findings, these results suggest that lack of proverb completion may be attributed to a selective, systematic and complete loss of the meaning representations for language units such as words and proverbs. In addition, pathological processes of focal atrophy with temporal predominance might selectively affect the semantic memory for language as a unit.
我们研究了因各种疾病导致皮质下感觉性失语症的情况下谚语完成现象。这种不完整仅在局灶性萎缩患者中观察到。这些患者在命名时表现出选择性和一致的单词理解障碍，没有语音提示效应。在因其他脑部疾病导致皮质下感觉性失语症的患者中，存在完成现象。在这些患者中，理解缺陷不是针对单词，或者未理解的单词不一致，并且观察到一些语音提示效应。在之前的一项研究中，我们报告说，在局灶性萎缩患者中，乘法表、序列号和星期名称的完成现象经常出现。结合目前的发现，这些结果表明，谚语完成的缺乏可能归因于语言单位（如单词和谚语）的意义表示的选择性、系统性和完全丧失。此外，以颞叶为主的局灶性萎缩的病理过程可能会选择性地影响语言的语义记忆作为一个整体。
