三个实验评估了理解能力好的和理解能力差的人的记忆技能，他们的解码技能是一致的。实验1和实验2通过比较不同长度、词汇性和具体性的单词的连续回忆来考察语音和语义对短期记忆的贡献。理解力差的人对语音操作(长度和词汇性)表现出正常的敏感性，但与他们的语义弱点一致，他们对抽象单词的回忆能力很差。实验3考察了言语和空间工作记忆。尽管理解力差的人获得了正常的空间跨度，但他们的语言跨度受到了损害。这些结果是在一个理论框架内讨论的，该理论框架认为，与阅读理解不良相关的记忆困难是特定于言语领域的，是语言障碍的伴随，而不是阅读理解失败的原因。(C)1999年学术出版社。
Three experiments assessed memory skills in good and poor comprehenders, matched for decoding skill. Experiments 1 and 2 investigated phonological and semantic contributions to short-term memory by comparing serial recall for words varying in length, lexicality, and concreteness. Poor comprehenders showed normal sensitivity to phonological manipulations (length and lexicality) but, consistent with their semantic weaknesses, their recall of abstract words was poor. Experiment 3 investigated verbal and spatial working memory. While poor comprehenders achieved normal spatial spans, their verbal spans were impaired. These results are discussed within a theoretical framework in which the memory difficulties associated with poor reading comprehension are specific to the verbal domain and are a concomitant of language impairment, rather than a cause of reading comprehension failure.
