The aim of this study was to investigate the preservation of semantic access in patients with severe neglect dyslexia for words and non-words. Patients were given the following tasks: (1) reading aloud letter strings (first basic reading task), (2) making semantic decisions (categorial and inferential judgements), (3) making semantic decisions and reading the letter strings immediately afterwards (semantic-reading tasks), (4) reading letter strings again (final basic reading tasks) and (5) auditory control tasks. Of 23 patients with visual neglect, four showed neglect dyslexia for both words and non-words. Of these four patients, three showed a performance in the semantic tasks that was as good as in the auditory condition. Moreover, the reading of the patients improved dramatically in the semantic-reading tasks but this was not maintained in the final basic reading task. Non-words showed only a minor improvement. Findings are discussed in terms of an interaction between the attentional system and the different reading routes, and provide evidence that semantic routes are less affected by neglect.
本研究的目的是调查患有严重忽视性失读症的患者对单词和非单词的语义通达保留情况。患者接受了以下任务：（1）大声朗读字母串（首个基本阅读任务），（2）做出语义判断（类别和推理判断），（3）做出语义判断并随后立即朗读字母串（语义阅读任务），（4）再次朗读字母串（最后的基本阅读任务）以及（5）听觉控制任务。在23名患有视觉忽视的患者中，有4名对单词和非单词均表现出忽视性失读症。在这4名患者中，有3名在语义任务中的表现与听觉条件下的表现一样好。此外，患者在语义阅读任务中的阅读能力有显著提高，但在最后的基本阅读任务中并未保持。非单词仅表现出轻微改善。研究结果从注意系统与不同阅读路径之间的相互作用方面进行了讨论，并提供了证据表明语义路径受忽视的影响较小。
