Although there is considerable evidence that grapheme and body units are involved in assembling phonology from print, there is little evidence supporting the involvement of syllabic representations. We provide evidence on this point from a phonological dyslexic patient (ML) who, as a result of brain damage, is relatively unable to read nonwords. ML was found to be able to perform tasks assumed to reflect processes involved in assembled phonology (i.e. segmentation, orthographic-phonologic conversion, and blending) when the units involved were syllables, but demonstrated considerable difficulty when they were onset, body, or phoneme units. Additionally, both ML and matched controls were much better able to find words in an anagrams task (Treiman & Chafetz, 1987) when they resulted from the combination of segments corresponding to syllables than when they did not. It is suggested that the relationship between print and sound is represented at multiple levels (including the syllable) (Shallice, Warrington, & McCarthy, 1983) and that ML's nonword reading impairment is the result of disruption of representations below the level of the syllable.
尽管有大量证据表明字形和音素单位参与了从印刷文字中构建语音，但几乎没有证据支持音节表征的参与。我们从一名语音失读症患者（ML）那里获得了关于这一点的证据，该患者由于脑损伤，相对无法阅读非词。研究发现，当所涉及的单位是音节时，ML能够完成被认为反映了构建语音过程（即分割、正字法 - 语音转换和混合）的任务，但当涉及的单位是首音、音素或音位单位时，ML则表现出相当大的困难。此外，在一个变位词任务中（Treiman & Chafetz，1987），当单词由对应于音节的片段组合而成时，ML和匹配的对照组都能更好地找到这些单词，而当不是这种情况时则不然。这表明印刷文字和声音之间的关系在多个层面（包括音节层面）上得到表征（Shallice、Warrington和McCarthy，1983），并且ML的非词阅读障碍是音节层面以下表征受到破坏的结果。
