我们报告一位因脑动脉梗塞而有后天性阅读障碍的病人KJ。他代表了一个异常清晰的“输出”深度阅读障碍的案例，具有明显的纯语义阅读模式。根据当前阅读的神经心理学模型，这种情况的严重程度与语义和语音表征的受损程度以及由此导致的两种文字处理途径之间的相互作用的不平衡直接相关。本研究旨在探讨是否一个创新的眼动支持干预结合词汇和分段治疗将加强语音处理，并导致衰减的极端语义过度参与KJ的单词识别过程。阅读性能进行了评估之前（T1）之间（T2）和治疗后（T3）使用语言错误和单词查看模式的分析。治疗提高了阅读的准确性沿着改变了错误分布，这表明恢复到更顺序的阅读。有趣的是，这与即时文字处理的动态相反，因为即使在T3，眼动分析仍然表明主要是整体策略。因此，除了记录治疗干预的成功之外，我们的结果还需要一个理论上重要的结论：实时字母和单词识别程序应该与语言输出的属性分开考虑。结合这两种观点可能会提供一个有前途的战略，为未来的评估和治疗评价。
We report on KJ, a patient with acquired dyslexia due to cerebral artery infarction. He represents an unusually clear case of an “output” deep dyslexic reader, with a distinct pattern of pure semantic reading. According to current neuropsychological models of reading, the severity of this condition is directly related to the degree of impairment in semantic and phonological representations and the resulting imbalance in the interaction between the two word processing pathways. The present work sought to examine whether an innovative eye movement supported intervention combining lexical and segmental therapy would strengthen phonological processing and lead to an attenuation of the extreme semantic over-involvement in KJ's word identification process. Reading performance was assessed before (T1) between (T2) and after (T3) therapy using both analyses of linguistic errors and word viewing patterns. Therapy resulted in improved reading aloud accuracy along with a change in error distribution that suggested a return to more sequential reading. Interestingly, this was in contrast to the dynamics of moment-to-moment word processing, as eye movement analyses still suggested a predominantly holistic strategy, even at T3. So, in addition to documenting the success of the therapeutic intervention, our results call for a theoretically important conclusion: Real-time letter and word recognition routines should be considered separately from properties of the verbal output. Combining both perspectives may provide a promising strategy for future assessment and therapy evaluation.
