title: Evaluating the Predictive Impact of an Emergent Literacy Model on Dyslexia in Italian Children: A Four-Year Prospective Cohort Study.
abstract: The strong differences in manifestation, prevalence, and incidence in dyslexia across languages invite studies in specific writing systems. In particular, the question of the role played by emergent literacy in opaque and transparent writing systems remains a fraught one. This research project tested, through a 4-year prospective cohort study, an emergent literacy model for the analysis of the characteristics of future dyslexic children and normally reading peers in Italian, a transparent writing system. A cohort of 450 children was followed from the last year of kindergarten to the third grade in their reading acquisition process. Dyslexic children were individuated (Grade 3), and their performances in kindergarten in textual competence, phonological awareness, and conceptual knowledge of the writing system were compared with a matched group of normally reading peers. Results showed the predictive relevance of the conceptual knowledge of the writing system. The study's implications are discussed.
