【摘要】：已有研究表明,工作记忆在语言理解中起着极为重要的作用,失语症作为一种以语言功能受损为主要表现的障碍,一直都是语言康复教育的研究的热点。越来越多的研究者开始探索失语症与工作记忆的关系。目前关于失语症与工作记忆的研究都集中于国外,主要针对是拼音语系的失语症患者,而关于汉语的研究尚属空白。因此在汉语语言背景下,对失语症的工作记忆特征进行研究是非常重要的。研究目的：通过采用不同的测试材料和任务方式,比较失语症患者与正常成人之间的工作记忆能力差别；探索失语症的工作记忆特征。研究方法：编制工作记忆测试材料,采用听觉复述和听觉再认两种任务,选择数字、实词、虚词三种测试材料,测试失语症患者在正序和倒序两种测试方法中的工作记忆广度。研究结果： 1.针对不同的测试材料,失语症组和对照组测得工作记忆广度有所差异。倒序复述中,失语症组的工作记忆广度由高到底则依次为数字、虚词、实词,对照组为数字、实词、虚词；倒序再认中,失语症组的平均记忆广度最高为数字,其次为实词,最低为虚词,而对照组出数字平均记忆广度最高外,实词和虚词并无差别。 2.失语症患者的数字平均工作记忆广度高于实词和虚词；复述任务中测得的平均工作记忆广度好于再认任务。结论： 1.失语症患者均工作记忆广度显著落后于正常成人； 2.失语症患者可能在使用记忆策略方面存在困难； 3.工作记忆广度测试可能并不能够作为一个很好的指标对失语症患者的语言行为进行预测； 4.流利型失语症的工作记忆能力好于非流利型失语症,工作记忆能力测试中,失语症被试完成复述任务比再认任务更容易,尤其是非流利型失语症；
[Abstract]:Previous studies have shown that working memory plays an extremely important role in language understanding. Aphasia, as a major obstacle with impaired language function, has always been a hot topic in language rehabilitation education. More and more researchers are exploring the relationship between aphasia and working memory. At present, the researches on aphasia and working memory are mainly focused on aphasia patients of Pinyin family, but the research on Chinese is still blank. Therefore, in the context of Chinese language, it is very important to study the working memory characteristics of aphasia. Objective: to compare the difference of working memory ability between aphasia patients and normal adults by using different test materials and task methods, and to explore the working memory characteristics of aphasia. Methods: the working memory test materials were compiled. The task of auditory repetition and auditory recognition was used to test the working memory span of aphasia patients in positive order and reverse order by selecting three kinds of testing materials: number, notional words and function words. Results of the study: 1. For different test materials, the working memory span of aphasia group and control group were different. In reverse sequence retelling, the working memory span of aphasia group was in turn number, function word, notional word, control group, number, notional word and function word. In inverted recognition, the average memory span of aphasia group was the highest, followed by notional word. The lowest was function word, while the control group had the highest average memory span, and there was no difference between notional word and function word. 2. The average working memory span of aphasia patients was higher than that of notional words and function words, and the average working memory span in retelling task was better than that in recognition task. Conclusion: 1. The working memory span of the patients with aphasia was significantly lower than that of the normal adults. 2. Aphasia patients may have difficulties in using memory strategies; 3. Working memory span test may not be a good indicator to predict the language behavior of aphasia patients. 4. The working memory ability of fluency aphasia is better than that of non-fluency aphasia. In the test of working memory ability, it is easier for aphasia subjects to complete retelling tasks than to recognize them, especially for non-fluency aphasia.
