After a stroke involving the left occipitotemporal cortex our patient shows a word-length effect and has problems to identify letters or numbers in strings of symbols. But he is normal in identifying isolated letters and in non-verbally categorizing even complex images such as faces or natural scenes. His cortical lesion is stretching from the visual word form area (VWFA) anteriorly causing additional problems to name visual stimuli and to match acoustic stimuli with images. We conclude that our patient suffers from pure alexia without deficits to identify even complex visual stimuli. Our results directly contradict several explanations for letter-by-letter reading.
在一次涉及左侧枕颞叶皮质的中风后，我们的患者表现出词长效应，并且在识别符号串中的字母或数字时存在困难。但他在识别单个字母以及对诸如面孔或自然场景等复杂图像进行非语言分类方面是正常的。他的皮质病变从前视觉词形区（VWFA）延伸，导致在命名视觉刺激以及将听觉刺激与图像匹配方面出现额外问题。我们得出结论，我们的患者患有单纯性失读症，在识别甚至复杂视觉刺激方面没有缺陷。我们的结果直接与逐字母阅读的几种解释相矛盾。
