摘要： 儿童在提取短时记忆系统的语音信息时,往往会造成部分信息的丢失和回忆量的下降,这种信息丢失量的多少与中央执行系统功能有着密切的联系。为了考察阅读障碍儿童的语音提取特点,挖掘他们记忆失败的本质,使用自由回忆和再认两种任务,考察阅读障碍儿童在无意义音节和汉语词汇上的提取特点,结果发现：（1）阅读障碍儿童在语音提取时,丢失的信息率要显著多于正常儿童,这种丢失可能是由于他们落后的中央执行功能所致;（2）阅读障碍儿童单纯的语音保持能力正常,但不擅长利用语义编码来促进短时记忆效果,而正常儿童却能够较好地利用语义线索。

Abstract: In the processing of information retrieving from short-term memory, dyslexic children lose some information and recall less information, because the quantity of recalling information is influenced by deficits of central executive system. This experiment designed two tasks: recalling no-sense syllable and Chinese glossary to find out the characteristics of phonetic retrieving in dyslexic children. The results are as followings:(1)In the tasks of phonetic retrieving, the dyslexic children lost more information than the normal children because of their deficits in central executive system.(2)In the tasks of keeping no-sense phonetic information, dyslexic children performed as well as the normal children. In the processing of retrieving phonetic information, dyslexic children had a lower ability to utilize semantic clue to help to memory than the normal children did.
