This volume presents the first truly systematic, multi-disciplinary, and cross-linguistic study of the language and writing system factors affecting the emergence of dyslexia. Bringing together a team of scholars from a wide variety of disciplines, it takes a dual focus on the language-specific properties of dyslexia and on its core components across languages and orthographies, to challenge theories on the nature, identification and prevalence of dyslexia, and to reveal new insights. Part I highlights the nature, identification and prevalence of dyslexia across multiple languages including English, French, Dutch, Czech and Slovakian, Finnish, Arabic, Hebrew, Japanese and Chinese, while Part II takes a cross-linguistic stance on topics such as the nature of dyslexia, the universals that determine relevant precursor measures, competing hypotheses of brain-based deficits, modelling outcomes, etiologies, and intergenerational gene-environment interactions.

A systematic multi-disciplinary study of the language and writing systems affecting the emergence of dyslexia. The study challenges theoretical claims that stem from single language research and single discipline viewpoints. It will appeal to students and researchers working on language acquisition, psycholinguistics and language disorders.
