Three dissociations were observed in a case of alexia: a disturbance of reading, without comparable disturbance of oral expression, oral comprehension, writing, or spelling aloud; a disturbance of the phonological reading process, without disturbance of the non-phonological reading process; a disturbance located at the level of the phonological stage, without disturbance of the perceptual and expressive stages. This pattern of results has been called phonological alexia.
阅读障碍，而口语表达、口语理解、书写或大声拼写没有类似障碍；语音阅读过程障碍，而非语音阅读过程无障碍；障碍位于语音阶段，而感知和表达阶段无障碍。这种结果模式被称为语音性失读症。
