We present a case study of a 43-year-old woman with chronic and stable pure alexia. Using a multiple baseline design we report the results of two different interventions to improve reading. First, a restitutive treatment approach using an implicit semantic access strategy was attempted. This approach was designed to exploit privileged access to lexical-semantic representations and met with little success. Treatment was then switched to a substitutive treatment strategy, which involved using the patient's finger to pretend to copy the letters in words and sentences. Reading using this motor cross-cuing strategy was 100% accurate and doubled in speed after 4 weeks of intervention. We propose that this patient's inability to benefit from the implicit semantic access treatment approach may be in part related to her inability to suppress the segmental letter identification process of word recognition.
我们呈现了一个关于一名43岁患有慢性稳定型单纯失读症女性的案例研究。采用多重基线设计，我们报告了两种不同改善阅读干预措施的结果。首先，尝试了一种使用隐性语义通达策略的恢复性治疗方法。该方法旨在利用对词汇语义表征的优先通达，但收效甚微。随后治疗转向替代治疗策略，即让患者用手指假装抄写单词和句子中的字母。使用这种运动交叉提示策略进行阅读的准确率为100%，且在干预4周后速度提高了一倍。我们认为，该患者无法从隐性语义通达治疗方法中获益，可能部分与她无法抑制单词识别中的分段字母识别过程有关。
