虽然在阅读性能的变化，恢复字母的读者已经描述了一些细节，没有以前的研究提供了深入的分析的基础自适应字处理策略。我们的工作检查了阅读性能的一个字母一个字母的读者，FH，在15个月的时间内，使用眼动方法来描绘恢复过程中的两个不同的时间点（T1，T2）。一个核心问题是，恢复的特点是要么回到正常的文字处理或细化和可能的自动化现有的病理策略，开发的障碍。更具体地说，我们假设一个字母接一个字母的阅读可以用至少四种不同的策略来执行，我们的工作试图区分这些选择。在恢复过程中，阅读性能得到了显著改善。从最左边的目标词的最右边的固定位置的转移相结合，许多小的和很少的较长的回退眼跳。显然，“逐字母阅读”采取了局部聚集的形式，很可能对应于分析的亚词汇单元的形成。这种模式在T2时更为明显，这表明阅读效率的提高可能是以最终难以恢复正常阅读为代价的。
Although changes in reading performance of recovering letter-by-letter readers have been described in some detail, no prior research has provided an in-depth analysis of the underlying adaptive word processing strategies. Our work examined the reading performance of a letter-by-letter reader, FH, over a period of 15 months, using eye movement methodology to delineate the recovery process at two different time points (T1, T2). A central question is whether recovery is characterized either by moving back towards normal word processing or by refinement and possibly automatization of an existing pathological strategy that was developed in response to the impairment. More specifically, we hypothesized that letter-by-letter reading may be executed with at least four different strategies and our work sought to distinguish between these alternatives. During recovery significant improvements in reading performance were achieved. A shift of fixation positions from the far left to the extreme right of target words was combined with many small and very few longer regressive saccades. Apparently, ‘letter-by-letter reading’ took the form of local clustering, most likely corresponding to the formation of sublexical units of analysis. This pattern was more pronounced at T2, suggesting that improvements in reading efficiency may come at the expense of making it harder to eventually return to normal reading.
