BACKGROUND
Spatial neglect is a neurocognitive disorder that affects perception, representation, and/or motor planning. Neglect dyslexia in spatial neglect after right hemisphere damage may co-occur with, or be dissociated from, other spatial neglect signs. Previous neglect dyslexia research focused on word-level stimuli and reading errors. Using single words for assessment may leave some people with neglect dyslexia undiagnosed, and assessment materials that are closer to texts read in real life may better capture neglect dyslexia.
METHOD
The authors tested reading in 67 right hemisphere stroke survivors with 4 types of text materials: words, phrases, an article, and a menu.
RESULTS
Accuracy on reading the menu and article texts was significantly poorer than reading the words and phrases. The hypothesis that assessment materials with ecological validity such as reading a menu and reading an article may be more challenging than reading single words and phrases was supported.
CONCLUSION
Results suggest that neglect dyslexia assessment after stroke should include text materials comparable to those read in everyday life. Increasing the spatial extent of training materials in future research might also yield better functional generalization after right brain stroke.
背景
空间忽视是一种影响知觉、表象和/或运动规划的神经认知障碍。右半球损伤后的空间忽视性失读症可能与其他空间忽视症状同时发生，也可能与之分离。先前的忽视性失读症研究集中在单词层面的刺激和阅读错误上。使用单个单词进行评估可能会导致一些忽视性失读症患者未被诊断出来，而更接近现实生活中阅读的文本的评估材料可能更能捕捉到忽视性失读症。
方法
作者测试了 67 名右半球中风幸存者的阅读能力，使用了 4 种文本材料：单词、短语、文章和菜单。
结果
阅读菜单和文章文本的准确性明显低于阅读单词和短语。评估具有生态有效性的材料（如阅读菜单和阅读文章）可能比阅读单个单词和短语更具挑战性的假设得到了支持。
结论
结果表明，中风后的忽视性失读症评估应包括与日常生活中阅读的文本材料相媲美的材料。在未来的研究中增加训练材料的空间范围，也可能会使右脑中风后的功能泛化更好。
