本研究的目的是探讨阅读障碍儿童工作记忆能力缺陷的特殊性，并探讨这些缺陷是否可以由加工缺陷或语言短期存储能力的损伤来解释。一组10岁的阅读障碍儿童与两组正常阅读儿童进行了比较，两组儿童的实际年龄和阅读年龄分别相匹配。对与语言和数字领域相关的工作记忆容量、短期容量和处理速度进行了测量。结果表明，阅读障碍儿童在工作记忆容量的所有测试中都表现较差，无论这些测试反映的是什么领域。他们较差的表现既不能用加工效率低下来解释，也不能用语言短期存储能力的缺陷来解释。阅读障碍儿童似乎普遍缺乏同时处理和存储语言信息的能力。(C) 1998学术出版社。
Aims of the study were to investigate the specificity of reading disabled childrens deficits in working memory capacity and to pursue whether their deficits could be accounted for by deficient processing or impairments in verbal short-term storage capacity. A group of 10-year-old reading disabled children was compared with two groups of normal reading children, matched for chronological age and reading age, respectively. Measures for working memory capacity, short-term capacity and processing speed related to the language and to the numerical domain were administered. Results indicated that reading disabled children performed worse on all measures of working memory capacity, irrespective of the domain which these measures reflected. Their poorer performance could neither be explained by inefficient processing nor to their deficits in verbal short-term storage capacity. Reading disabled children seem to have a general lack of capacity for the concurrent processing and storage of verbal information. (C) 1998 Academic Press.
