Developmental dyslexia is now a recognized disorder in many literate societies. On its website, the International Dyslexia Association boasts affiliated branches on every continent and in as many as 40 countries. Yet to date, far more scientific research has been reported about dyslexia in English than in any other language. It is therefore not surprising that many misconceptions still exist about the very existence, the manifestation, and the causes of dyslexia in languages other than English. For example, a common lay belief is that dyslexia is more common among speakers/readers of English because the ‘chaotic’English orthography is difficult to learn; in contrast, dyslexia is thought to be virtually nonexistent in ‘easy phonetic’orthographies such as Finnish and Spanish. Similarly, a popular belief about Chinese is that its logographic script requires rote memorization of thousands of picture-like characters and therefore reading difficulties of the sort observed in English must not exist among Chinese readers. Fortunately, the situation is changing and dyslexia is now being studied in a large variety of languages (see Goulandris, 2003). It is becoming clear that, although many of the lay ideas about dyslexia are inaccurate, they nevertheless reflect an intuitive understanding of one important fact, namely that reading and writing skills are influenced by the characteristics of different writing systems (see chapters by Frost, Hanley, and Treiman & Kessler this volume for further discussion of this).This chapter considers how such influences affect the manifestation of dyslexia in different languages. More specifically, a review is presented of what is currently known about dyslexia in various non-English languages and writing systems with respect to two main issues. The first is how various characteristics of written
