“…The most common hypothesis is the phonological theory which suggests that difficulties experienced by dyslexics in reading new words are generally explained in terms of their poor phonological skills (Casalis, 1995;Sprenger-Charolles, Cole, Larcet, & Serniclaes 2000;Casalis, 2003;Grainger, Bouttevin, Truc, Bastien, & Ziegler 2003), especially phonemic awareness, phonological short-term memory (Snowling, 2000) and more recently, the speed of lexical access (Wolf and Bowers, 1999). Other hypotheses showed that morphological awareness had an important part in reading acquisition (Colé, Marec-Breton, Royer, & Gombert 2003;Marec-Breton, Gombert, & Colé 2005) and dyslexic children seem to over-use this capacity to compensate their difficulties in reading. Visuo-attentional hypothesis (Ans, Carbonnel, & Valdois 1998;Valdois, Bosse, Ans, Carbonnel, Zorman, & David 2003) considers that a visuo-attentional deficit can also be present in dyslexia and reduce the perceptual span.…”
