DYSLEXIA AND THE
PHONOLOGICAL MODEL
Over one hundred years ago, in November 1896, a doctor in Sussex, England, published the first description of the learning disorder that would come to be known as developmental dyslexia. "Percy F.,... aged 14,... has always been a bright and intelligent boy," wrote W. Pringle Morgan in the "British Medical Journal," "quick at games, and in no way inferior to others of his age. His great difficulty has been--and is now--his inability to learn to read.” (Sec 3)
In that brief introduction, Morgan captured the illness that has intrigued and frustrated scientists for a century. In 2000 as in 1896, reading ability is taken as a substitute for intelligence; most people assume that if someone is smart, motivated and schooled, he or she will learn to read. But the experience of millions of dyslexics, like Percy F., has shown that assumption to be false. In dyslexia, the relation between intelligence and reading ability breaks down.
Early explanations of dyslexia in the 1920s, held that defects in the visual system were to blame for the reversals of letters and words thought to typify dyslexic reading. Eye training was often prescribed to overcome these alleged visual defects. Later research has shown, however, that children with dyslexia are not unusually prone to reversing letters or words and that the deficit responsible for the disorder is related to the language system. In particular, dyslexia reflects a deficiency in the processing of the distinctive linguistic units, called phonemes that make up all spoken and written words. Current linguistic models of reading and dyslexia now provide an explanation of why some very intelligent people have trouble learning to read and performing other language-related tasks.
Over the past twenty years, a consistent model of dyslexia has emerged that is based on phonological processing. The phonological model is consistent both with the clinical symptoms of dyslexia and with what neuroscientists know about brain organization and function. To understand how the phonological model works, one first has to consider the way in which language is processed in the brain. Researchers theorize the language system as a hierarchical series of modules or components, each devoted to a particular aspect of language. At the upper levels of the hierarchy are components involved with semantics (vocabulary or word meaning), syntax (grammatical structure) and discourse (connected sentences). At the lowest level of the hierarchy is the phonological module, which is dedicated to processing the distinctive sound elements that constitute language.
Next, we need to tackle the many misconceptions associated with dyslexia. Many people acquaint having a learning disability as having a disease. This is completely false, dyslexia is not a disease, and therefore there is no magic pill that can cure it. Actually, there is no cure and it cannot be outgrown. According to the journey into dyslexia, “it is a lifelong issue.” However, it is manageable with the assistance and resources, those with dyslexia can continue to keep up and retain their grade level in
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.
Language is a skill that, if used properly, can open up a variety of opportunities in life. Throughout the readings of “Homemade Education” by Malcolm X and “Living with Dyslexia” by Gareth Cook, we see many difficulties and challenges that people overcome when they are put in the face of language. Like many things, there are many different aspects that shape the way we understand the art of language. Throughout culture, perspective, and language we see all the components that make language so powerful. It is made very clear, that language has the power to promote the shaping of one’s identity.
In order to understand the specific reading problems associated with dyslexia, it is important to know how the brain conceptualizes language. The brain recognizes language in a hierarchical order. The upper levels of the hierarchy deal with semantics (the meaning of words), syntax (grammatical structure), and discourse (connected sentences). The lowest levels of the hierarchy deal with breaking words into separate small units of sound called phonemes. Thus, before words can be comprehended ...
To begin with, dyslexia is not a something that can be seen right away. People do not have symptoms like nausea or congestion to show that have dyslexia. Dyslexia is a disability that happens in the brain. Even though it can not always be physically seen, there are a few ways to tell if someone has dyslexia. If a child has dyslexia, it can be shown by the child reading with pauses or reading the words incorrectly by placing another word in instead of the one written down. An example would be by confusing the word ‘cat’ with bat or word like “fell/fall and who/how” (Dyslexia) There can be many possible reasons for misreading these words, one reason would be because the brain is just too tired to be able to connect what it sees to what it is supposed to sound like. Non dyslexic people can tell how words are supposed to sound by dividing the word into “individual phonemes” (V., Nathan). Phonemes are similar to syllables. Except there can be many phonemes in a one syllable words. Phonemes are the units of sounds words. An example is the words ‘bag.’ If divided by phon...
This is a subject and disorder near and dear to my heart. My personal experience with dyslexia, with myself and my daughter, has given me great insight into what dyslexia is, what the signs are, and how soon you can detect the potential for problems. It is not always the case that dyslexia is the sole source of reading and reading comprehension difficulties, there are other disorders that can exist at the same time, and this is important to know in order to help students improve their reading abilities. But, dyslexia will not only affect reading abilities and reading comprehension. It can affect writing, spelling, math, memory, listing comprehension, self-esteem, social skills, the ability to understand sarcasm, understanding spatial concepts,
Dyslexia is one of the most common neurobehavioral disorders that haunt adolescents throughout their childhood. Commonly known as a reading disability (RD), dyslexia is a hereditary complex trait that occurs in five to seventeen percent of people. Neuroimaging studies show that dyslexic individuals display abnormal brain function compared to fluent readers when challenged with reading assignments (7). The exact genes that code for dyslexia are not certain, however substantial studies have potentially linked dyslexia to the KIAA0319 gene, the DCDC2 gene, and the DYX1 gene. The severity of each case is largely determined by environmental factors such exposure to reading and professional intervention. Significantly, the interplay between these external influences and innate genetic characteristics ultimately determine the performance of the dyslexic individual.
There are various symptoms that help identify dyslexia; such as poor reading and spelling abilities, switching the directions of letters in words, and problems building short-term memory (Thomson, 2009). There are many other sym...
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 ...
“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 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.
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.
Dr. James Kerr, the first person to notice the signs and symptoms of dyslexia in 1896, taught at a school and initially became concerned with the children unable to read. Unknowingly, he came to the conclusion that the inadequate readers suffered from blindness. His observation had nothing to do with poor vision; although, in some areas of Britain and Scandinavia the overall condition is still labeled as blindness. (Dyslexia) Karl Kussman, receives recognition as the first person to give the condition its name due to the fact that the word derived from Greek origin. Its prefix dys means “difficult” while the suffix lexis means “words”. (Dyslexia: Get pg. 8) Presently, the name for these specific signs and symptoms mainly deals with the struggle to read are dubbed as dyslexia. The World Federation of Neurology termed the definition of dyslexia in 1968 as “A disorder in children who, despite conventional classroom experience, fail to attain the

Many students struggle with learning disabilities. Two common disabilities are Dyslexia and Dysgraphia. “According to the latest dyslexia research from the National Institutes of Health, Dyslexia affects 20 percent of Americans” (“What is Dyslexia?”) Dysgraphia is difficulty with writing that sometimes accompanies Dyslexia. Students that have Dyslexia and Dysgraphia will struggle with vocabulary, grammar, and punctuation, but there is help.
