“…The observation that lexicalization of Hebb sequences was reliable for the control group, but not so for the group with dyslexia, suggests that problems with serial-order learning may be seen as a symptom of dyslexia that leads to impaired lexical representations (we acknowledge again, though, the lack of a reliable interaction here and, therefore, the need to strengthen this statistical claim in future work). This account converges with the reported difficulties of pseudoword learning in dyslexic children (e.g., Otto, 1961;Messbauer & deJong, 2003) and adults (Di Betta & Romani, 2006). Poor lexical quality, in turn, affects reading and spelling performance (see Perfetti, 2007).…”
