背景：语音文本失读症（PhTA）是一种阅读障碍，其中伪词的阅读受到损害，但只有在阅读文本时，真实单词的阅读才会受到损害。当单词单独呈现时，口语阅读准确性仍然保持良好，但当以文本形式呈现时，就会出现语音失读症 (PhA) 中常见的词性效应。目的：确定重复启动是否可以在文本阅读过程中加强和/或维持单词的激活。方法和程序：我们训练 NYR，一名 PhTA 患者，使用一种策略，即句子构建，旨在提高阅读文本中单词的准确性。该策略要求 NYR 首先阅读初始单词，然后通过逐步添加连续单词来构建句子，利用重复启动的好处来提高准确性。结果与结果：使用该策略时，NYR 不仅对使用该策略练习的句子以及未练习的句子都显示出更高的准确性。此外，与不使用该策略相比，使用该策略时 NYR 在理解测试中表现更好。结论：根据将重复启动与提高神经处理效率联系起来的研究，我们的结果表明，使用这种补偿策略可以通过暂时提高语音激活水平来提高阅读准确性和理解力。
Background: Phonologic text alexia (PhTA) is a reading disorder in which reading of pseudowords is impaired, but reading of real words is impaired only when reading text. Oral reading accuracy remains well preserved when words are presented individually, but when presented in text the part‐of‐speech effect that is often seen in phonologic alexia (PhA) emerges.Aims: To determine whether repetition priming could strengthen and/or maintain the activation of words during text reading.Methods & Procedures: We trained NYR, a patient with PhTA, to use a strategy, sentence building, designed to improve accuracy of reading words in text. The strategy required NYR to first read the initial word, and then build up the sentence by adding on sequential words, in a step‐wise manner, utilising the benefits of repetition priming to enhance accuracy.Outcomes & Results: When using the strategy, NYR displayed improved accuracy not only for sentences she practised using the strategy, but unpractised sentences as well. Additionally, NYR performed better on a test of comprehension when using the strategy, as compared to without the strategy.Conclusions: In light of research linking repetition priming to increased neural processing efficiency, our results suggest that use of this compensatory strategy improves reading accuracy and comprehension by temporarily boosting phonologic activation levels.
