在计算机化的注意力技能测试中，将30名患有特殊记忆障碍的学习障碍儿童的表现与30名匹配的对照组进行了比较。连续性能测试（CPT）提供了遗漏错误、委托错误和对颜色-字母组合目标的平均响应率的度量。LD组表现出更多的遗漏错误和较慢的反应速度，但在委托错误方面与对照组没有差异。从信号检测的角度对结果进行了解释，表明LD组表现为加工资源分配效率低下，而不是注意力缺陷。强调了将残疾儿童划分为同质认知亚群的重要性。
The performance of 30 learning disabled (LD) children with specific memory disability was compared to 30 matched controls on a computerized test of attentional skills. The Continuous Performance Test (CPT) provided a measure of omission errors, commission errors, and average rate of responding to a color-letter combination target. The LD group showed more omission errors and a slower rate of responding, but did not differ from controls on commission errors. The results were interpreted from a signal detection perspective and suggested that the LD group showed inefficient allocation of processing resources rather than an attentional deficit. The importance of dividing LD children into homogeneous cognitive subgroups was stressed.
