发育性阅读障碍患者的单词阅读速度缓慢可能源于字符串处理障碍，这反过来又反映了视觉注意力缺陷。我们确实发现有阅读障碍的成年读者的识别时间阈值显着提高。然而，他们的位置分布很难与任何讨论的视觉注意力缺陷假设以及阅读困难读者缺乏字符串处理系统的预测相一致，因为他们在数字和字母串上表现出与正常阅读对照类似的 M 形位置分布。 (c) 2005 Elsevier Ltd. 保留所有权利。
The slow word reading of developmental dyslexics may stem from a string processing impairment which in turn reflects visual attentional deficits. We indeed found substantially enhanced recognition time thresholds in the dyslexic adult readers. However, their position profiles were hard to reconcile with any of the discussed visual attentional deficit hypotheses and with the prediction that dyslexic readers suffer from an absent string processing system as they exhibited similar M-shaped position profiles for digit and letter strings as the normal reading controls.
