1. Dyslexia ResearchJust as our current understanding of literacy has formed from multiple lines of research across a wide range of disciplines, our understanding of dyslexia has also evolved. Multifaceted research in these two related fields has led to a broad understanding of the terms “literacy” and “dyslexia.” As subject specialists focus on investigations within their own disciplines; others attempt to bring these divergent lines of research together to form coherent pictures of literacy and dyslexia that can be merged with the political context of government and institutional policy makers as well as the perspectives of groups pressure groups such as the British Dyslexia Association. Rassool (2009) aimed for a paradigm, a generally accepted perspective, on literacy, when she conceived the concept of literacy as a “regionalized field of study” (Rassool, 2009, p. 21). In order to take into account the multiple facets of research and social and political influences that affect our concept of literacy, she developed a conceptual framework with lenses for studying individual areas that can be discussed as distinct entities or related among themselves. them. Similarly, Morton and Frith (cited in Reid, 2009, p. 14) discuss a causal modeling framework that explains dyslexia based on the interactions of the environment with the three factors of biology, cognition and behavior. Figure 1: Framework causal modeling (after Frith, 1995, p.11) From Figure 1, we can see that there are links between the three layers of the model and that the environment can interact with any of these layers.
