This model proposed two main pathways of meaning pathways:direct and indirect pathways vocabulary voice channels.Using direct access,the reader will be perceived in terms of the overall analysis phase characteristics stored in the mental lexicon,the reading must be carried out from the mental lexicon extraction of the whole word shape.So not previously encountered the word or fake learned words and non-words,the channel can not do anything; use of voice channels,as English is the phonograph,the reader can form words - to encode audio and visual information transformation rules,analysis phase will be perceived combination of words to phonemes stored in the mental lexicon,the reading must be a voice from the mental lexicon extraction.Then touch tone sound conversion rules do not meet the form of words,the channel will be an error response.Therefore,a mature reader must be able to make good use of these two pathways.Dyslexia refers to the surface the reader can access the skillful use of indirect speech,but in the direct pathway has shown vocabulary specific difficulties,and the performance of deep dyslexia is just the opposite.
