1. Dyslexia Research

Just as our current understanding of literacy has formed from multiple lines of research over a diverse range of disciplines, so has our understanding of dyslexia. The multifaceted research in both these related fields has led to a wide scope of understanding for both the terms ‘literacy’ and ‘dyslexia’. As subject specialists concentrate on investigations in their own disciplines; others attempt to draw these divergent lines of research together to form coherent images of both literacy and dyslexia that can be amalgamated with the political context of policy-makers in governments and institutions as well as those views of pressure groups such as the British Dyslexia Association.

Rassool (2009) was aiming towards a paradigm, a generally accepted perspective, on literacy, when she devised a concept of literacy as a ‘regionalised field of study’ (Rassool, 2009, p.21). In order to account for the multifaceted research, social and political influences that affect our concept of literacy, she developed a conceptual framework with lenses to study the individual areas which can be discussed as separate entities or linked together. In a similar fashion Morton and Frith (cited in Reid, 2009, p.14) discuss a causal modelling framework which explains dyslexia as a function of the interactions of the environment with the three factors of biology, cognition and behaviour.

Figure1: Causal Modelling framework (after Frith, 1995, p.11)

From figure 1 it can be seen that there are links between all three layers of the model and that the environment can interact with any one of these layers.

The Biological Level

The biological level examines the potential biological origins of the behavioural difficulties that are seen...

  • The Crisis in Adolescent Literacy

    2250 Words  | 5 Pages

    Finding a definition of literacy is not as easy as it sounds. The Webster definition says that to be literate is to be” able to read and write.” But to some researchers, this definition is too simplistic, leading to multiple models of literacy. Most Americans adhere to the autonomous model, which falls closest to the standard, dictionary definition. Believers in this form say that literacy is a cognitive activity that students learn like any other basic skill. It has a set of proficiencies that one must master in order to be capable of decoding and encoding text (Alvermann, 2009; SIL International, 1999). A competing theory is the ideological model, which claims literacy is intrinsically linked to culture, and therefore what constitutes a “literate” individual is ever-changing. Society is the largest influence on literacy, according to this thought, and it is affected by politics, religion, philosophy and more (Alvermann, 2009; SIL International, 1999). These two are just the tip of the iceberg. For example, some studies recognize “literacy as competence,” which is a “measure of competence to do a given task or work in a given field,” (SIL International, 1999) such as being computer literate. Although more researchers are recognizing and exploring multiple literacies, the one that most influences American schools is the autonomous, cognitive model – the ability to read and write. For many, it seems a simple task, but millions of adolescents are struggling or reluctant readers, and there are many reasons why young readers have difficulty with reading.

  • The Pros And Cons Of Dyslexia

    725 Words  | 2 Pages

    Dyslexia is the most prominent learning disability here in the United State but, it is also the most misunderstood. For centuries, those with dyslexia have been labeled as stupid and incompetent, when in fact they extremely intelligent, excelling in areas such as art, science and music. Due to our lack of knowledge and understanding, we as a nation are ignorant, deeming truth to the stereotypes that have long been associated with this so called “disease.” In order to reverse the damage that has already been done, we must differentiate fact from fiction. In order to fully understand dyslexia, individuals need to be provided with resources that address every aspect of the disability, including what it is, the possible causes, signs, symptoms and treatments available. Awareness is key to change.

  • Wilson Language Program: The Key to the Destruction of Dyslexia

    1564 Words  | 4 Pages

    Robert Buck once said, “If children can’t learn the way we teach, then we have to teach the way they learn.” The Wilson Language Program has become disclosed to amplify this mentality. Dyslexia is a common disease among ten to fifteen percent of the United States, where a human being has trouble in learning to read or interpret words, letters, and other symbols. Programs are reaching out to try to terminate as much distress of dyslexia as possible. Up and coming programs, The Wilson Language Program for example, are making their best efforts to start working with children from a young age with the slight signs of this common problem. Catching dyslexia earlier in life brings more assurance that the child’s future will have little to no setbacks or disadvantages for success. In order to enhance the regressive literacy of dyslexic individuals, the Wilson Language Program is progressively being implemented into regular schooling to ensure that reading standards are met, through structure, hours of research, copious practice, and strong evidence.

  • The Phonological Model of Dyslexia

    1723 Words  | 4 Pages

    Doctor Morgan of Sussex, England, published the first case of what is now known as dyslexia in 1896. Dr. Morgan wrote about Percy F, a 14-year-old boy who was intelligent, bright, quick with learning games, and the intellectual equal of his peers. He fell behind, however, in his inability to learn how to read. Today, as in 1896, most people associate intelligence with the ability to read, but Percy F and the experience of millions of people with dyslexia breaks down the relationship between reading and intelligence (1). But, researchers were left with the question, "What causes dyslexia if intelligence is not the marker?

    ...ed by most, and how dyslexia can cause problems with reading comprehension. It also discussed ways that we can mitigate these problems for dyslexic people, but these skills can and should be used by all learners. Reading comprehension is a perishable skill, one that if you don’t work on increasing your reading ability by building your vocabulary, learn to read effectively, or using the correct reading strategies for the type of reading material being studied will diminish. Even with the largest vocabulary, if the words are not understood literacy cannot be achieved. Literacy is the key to comprehensive reading. It also gave some of the tools for reading and understanding different types of literature and how to get the important information out of each one. Edmund Burk said “To read without reflecting is like eating without digesting” (Gallagher, 2003, p. 11).

    Dyslexia is one of several distinct learning disabilities. It is a specific language based disorder of constitutional origin characterized by difficulties in single word decoding, usually reflecting insufficient phonological processing abilities. These difficulties in single word decoding are often unexpected in relation to age and other cognitive and academic abilities; they are not the result of generalized developmental disability or sensory impairment. Dyslexia is manifest by ...

  • Dyslexia Jake Horner Analysis

    “The Extraordinary Characteristics of Dyslexia” by Jake Horner is a definition essay on what it means to be dyslexic. He incorporates his own life story to support his definition and his ideas in his essay. Dyslexia is looked upon as a disability that should be treated even though dyslexia has to do with the way your brain processes the information given to you. Horner includes two types of thinkers, spatial and linear. Spatial thinkers are the dyslexic people in the world, and linear thinkers are the non-dyslexic people in the world (Horner 493). As I read this essay, it made me reflect.

  • Literacy

    924 Words  | 2 Pages

    Literacy is defined as “the ability to use available symbol systems that are fundamental to learning and teaching for the purposes of comprehending and composing, for the purposes of making and communicating meaning and knowledge” (Stock, 2012), and it is one of the most essential skills that an early year student will learn. Literacy serves to provide the building blocks for the continued knowledge acquisition and general education of individuals of all ages; by working to understand and identify how and why literacy is taught using the structured literacy block format in Australian schools, and in identifying the benefits of utilizing this type of tool for teaching literacy in student’s early years, it will be possible to gain a better understanding of the organization, planning, and teaching approaches that are used in a literacy block approach. A sample standard literacy block will be provided, offering the means of understanding the applications of the tool, which will serve to further stress the necessity of this tool’s usage.

  • Etiology of Developmental Dyslexia

    2254 Words  | 5 Pages

    The long disputed debate about the primary cause of dyslexia is still very much alive in the field of psychology. Dyslexia is commonly characterized as a reading and writing impairment that affects around 5% of the global population. The disorder has frequently been hypothesized to be the result of various sensory malfunctions. For over a decade, studies have made major contributions to the disorder's etiology; however, scientists are still unclear of its specific causal. Initially, dyslexia was thought to be a reading disorder in children and adults (1). Later it was suggested to consist of both a visual and writing component, therefore characterizing it as more of a learning disability which affected people of normal intelligence's ability to perform to their fullest potential (5). In the current research, cognitive and biological perspectives have often been developed independently of one another failing to recognize their respective positions within the disorder's etiology.
