8- and 11-yr-old reading-disabled children were compared in two experiments with controls matched on intelligence and age. Exp. 1 measured duration of visual information store by means of a separation threshold technique. Exp. II determined the rate of transfer from visual information store to short-term memory using a backward masking technique. Results from Exp. I showed that at each age specific reading-disabled children had significantly longer durations of visual information store than controls. The difference between the reading ability groups decreased with increasing age. Exp. II demonstrated that rate of transfer of information was significantly slower for specific reading-disabled children than for controls at both age levels. In contrast to Exp. I, this difference increased with increasing age. The results are considered in terms of their possible relevance to developmental lag theories. The evidence indicates that the development of visual information processing in reading-disabled children is similar to that in controls but occurs at a slower rate.
在两项实验中，对8岁和11岁的阅读障碍儿童与在智力和年龄上相匹配的对照组儿童进行了比较。实验1通过分离阈值技术测量视觉信息存储的持续时间。实验2使用反向掩蔽技术确定从视觉信息存储到短期记忆的转移速率。实验1的结果表明，在每个年龄段，特定的阅读障碍儿童的视觉信息存储持续时间都明显长于对照组。阅读能力组之间的差异随着年龄的增长而减小。实验2表明，在两个年龄水平上，特定阅读障碍儿童的信息转移速率都明显慢于对照组。与实验1相反，这种差异随着年龄的增长而增加。从这些结果与发展滞后理论的可能相关性方面对其进行了考量。证据表明，阅读障碍儿童视觉信息处理的发展与对照组相似，但速度较慢。
