报告了与发展性阅读障碍相关的短期记忆存储、长期记忆存储和语义记忆的详细研究。对 51 名阅读困难儿童和 28 名对照儿童进行了测试，在阅读困难儿童中发现了以下缺陷。短期记忆功能在存储容量和递减率方面均受到损害。视觉材料的长期记忆功能正常，但言语长期记忆功能受损。有证据表明将新材料纳入语义记忆存在困难，但从该系统内访问信息的速度似乎正常。记忆缺陷的重要性与以下假设相关讨论：儿童阅读障碍是字形-音位和字形-语义阅读途径的双重缺陷。
A detailed investigation of short-term memory storage, long-term memory storage and semantic memory associated with developmental dyslexia is reported. Fifty-one dyslexic and 28 control children were tested, and the following deficits were found amongst the dyslexic children. Short-term memory functions were impaired both with respect to storage capacity and rate of decrement. Long-term memory functions for visual material were normal but verbal long-term memory functions were impaired. There was evidence of difficulties in incorporating new material into semantic memory but the rate of accessing information from within this system appeared to be normal. The significance of the memory deficits is discussed in relation to the hypothesis that childhood dyslexia is a double deficit of the graphemic-phonemic and graphemic-semantic reading routes.
