Neglect dyslexia is a reading disorder which affects the identification of portions of words or sentences and is typically due to right-brain damage. Caramazza and Hillis (1990a, b) proposed a model of representation of words whereby various patterns of neglect dyslexia are attributed to selective impairment to the different forms of representation. According to the model, patients with first and second level deficits will "neglect" those parts of horizontally presented words that fall on one side of the retina, or on one side of the string centre, respectively, but will read vertically presented words without errors. A patient with a third level deficit will neglect letters at the beginning of the word irrespective of whether they fall on the right or left half of the retina, or on the right or the left of the word centre. In the present paper I describe an atypical pattern of neglect errors that is not easily explicable by this model and is better interpreted as an object-based neglect within an ego-centred frame of reference.
忽视性失读症是一种阅读障碍，它会影响对单词或句子部分内容的识别，通常是由右脑损伤引起的。卡拉马扎和希利斯（1990a，b）提出了一种单词表征模型，据此各种忽视性失读症模式被归因于对不同表征形式的选择性损伤。根据该模型，一级和二级缺陷的患者将分别“忽视”水平呈现单词中落在视网膜一侧或字符串中心一侧的那些部分，但能够正确阅读垂直呈现的单词。三级缺陷的患者会忽视单词开头的字母，无论这些字母落在视网膜的右半侧还是左半侧，或者单词中心的右侧还是左侧。在本文中，我描述了一种非典型的忽视错误模式，该模型难以对其进行解释，而将其更好地解释为以自我为中心的参照系内基于对象的忽视。
