The Dual-Route Cascaded (DRC) model is a highly influential computational model of visual word recognition and reading aloud. It proposes two distinct but interacting pathways for converting orthography to phonology. The lexical route involves accessing stored representations of known words in an orthographic lexicon, which then activates corresponding entries in a phonological lexicon. This route is necessary for correctly reading irregular words (e.g., 'yacht', 'colonel'), whose pronunciation does not follow standard grapheme-to-phoneme conversion rules. The non-lexical route, conversely, applies a set of rules to translate graphemes into phonemes and is used for reading regular words and novel non-words (e.g., 'plim'). A patient suffering from a specific reading disorder consistently fails to read irregular words correctly (e.g., pronouncing 'have' to rhyme with 'gave'), yet demonstrates no difficulty in reading regular words or non-words. Within the DRC framework, this patient's profile is a classic presentation of:
