Recent evidence from patients with progressive language disorders and dementia has been used to suggest that phonological and orthographic processing depend on intact semantic memory. These claims challenge the traditional view that there are functionally separate modules in the language system. The effect of a severe, but nonprogressive, semantic impairment on phonological and orthographic processing was evaluated in LA, a mentally retarded child with hyperlexia. Knowledge of a word's meaning did not affect LA's word repetition, a measure of phonological processing, or his acquisition and retention of orthographic patterns for writing to dictation low-frequency words with exceptional spellings. These findings support the assertion that both orthographic and phonological whole-word representations can be acquired, stored, and retrieved in the absence of a functional link to semantic memory.
近期针对患有进行性语言障碍和痴呆症患者的证据表明，语音和正字法处理依赖于完整的语义记忆。这些说法挑战了语言系统中存在功能上相互独立模块的传统观点。我们对一名患有高读症的智障儿童LA进行了评估，以研究严重但非进行性的语义损伤对语音和正字法处理的影响。对单词意义的了解并未影响LA的单词重复（一种语音处理的测量方法），也未影响他对具有特殊拼写的低频听写单词的正字法模式的习得和记忆。这些发现支持了这样一种观点，即在缺乏与语义记忆的功能联系的情况下，正字法和语音的全词表征都可以被习得、存储和检索。
