汉语失语症心理语言评价与汉语标准失语症检查对命名困难定性的比较

目的：探讨汉语失语症心理语言评价(PACA)与汉语标准失语症检查(ABC)哪一方法可以揭示命名困难产生的根源。方法：采用汉语失语症心理语言评价，以及汉语标准失语症检查的相关测验对2例命名困难的失语症患者进行检查。结果：例1的ABC名词听理解、名词阅读理解、图画命名完全正常，但词复述和命名言语含糊不清。PACA的名词听理解、同义词判断检查提示该患者的语义系统接近正常；语音判断、读音一致性判断及起始音分类基本正确，表明语音输出词典正常；复述检查未显示出词长效应；根据PACA确定该患者的语言损害主要定位于言语运动计划水平。例2的ABC名词听理解与阅读理解全部正确；字、词复述全部正确；命名困难。PACA的听理解、阅读理解测验表明该患者存在词汇语义损害。语音输出词典有关测验表明语音输出词典的损害比语义认知更严重。词复述和非词复述正常，提示词典后加工正常。结论：汉语失语症心理语言评价可以揭示命名产生的根源，有帮于分析和确定造成命名困难的语言加工受损水平，从而为命名困难受损的认知加工进行针对性的治疗。

Identifing the nature of naming difficulty in aphasics with Psycholinguistic Assessment in Chinese Aphasia and Aphasia Battery for Chinese

Objective:To identify which aphasia assessment tools, Psycholinguistic Assessment in Chinese Aphasia (PACA) and Aphasia Battery for Chinese(ABC), can reveal the source of naming difficulty in aphasics. Method: 2 aphasics with naming difficulty were examined respectively with both assessment tools. Result: Case 1 showed normal auditory and reading comprehension of noun and naming in ABC, but slurred speech in word repetition and picture naming. He showed nearly normal semantic system in word auditory comprehension and synonym judgment tests in PACA; character phonologic judgment, character pronunciation consistency judgment and initiation sound classification tests were normal. The impairment of language processing was identified at speech motor planning level through PACA. Case 2 showed normal auditory and reading comprehension of noun, normal word repetition and naming difficulty in ABC. She showed obvious word semantic impairment in auditory and reading word comprehension tests, and phonological output lexicon was impaired more severely than semantic system in PACA. Normal word and non-word repetition suggested normal post-lexicon processing. Conclusion: PACA could reveal the source of word naming difficulty and help us to analyze and identify the impaired level of word processing in word naming. PACA could provide more specified information for naming difficulty treatment.
