在这项研究中，我们报告了对两名患有获得性阅读障碍的患者的调查，其特征是逐字母阅读，整个单词的阅读显然是不可能的。事实证明，这种逐字阅读的现象不能用视觉或知觉因素来解释，也不能用视觉理解广度的损伤来解释。记录了异常缓慢的阅读速度，并建立了字长和阅读速度之间的明确关系。被认为最大化整个单词阅读的任务的表现受到损害，同时阻止了逐字母阅读的可能性，即阅读脚本和速视演示的阅读。这两名患者在图像解释任务中的令人满意的表现表明，同时失认症的两个组成部分，即逐字阅读和复杂场景的零碎感知，是分离的。我们考虑了逐字母阅读的三种替代解释，我们得出的结论是，在这种类型的获得性阅读障碍中，获得视觉单词形式的系统受到了损害。
In this study we have reported our investigation of two patients with an acquired dyslexia characterized by letter-by-letter reading, whole word reading being apparently impossible. It has been shown that this phenomenon of letter-by-letter reading cannot be accounted for by visual or perceptual factors nor by impairment of visual span of apprehension. The exceptionally slow speed of reading was documented and a clear relationship between word length and reading speed established. Performance on tasks considered to maximize whole word reading which at the same time prevent the possibility of letter-by-letter reading, namely, reading script and reading with tachistoscopic presentation, was impaired. The satisfactory performance of these two patients on tasks of picture interpretation suggests that the two components of the syndrome simultanagnosia, letter-by-letter reading and piecemeal perception of complex scenes, are dissociable. Three alternative explanations of letter-by-letter reading are considered and we conclude that in this type of acquired dyslexia there is damage to the system through which a visual word-form is attained.
