Dyslexia research

Dyslexia is about having problems with a culture's visual notation of speech. The form of the notation varies according to the writing system adopted and developed by each culture. Much of the early dyslexia research was based in cultures that adopted a Latin Alphabetic writing systems.

Dyslexia and language orthography

The Orthography of language has its origins in the Writing Systems developed or adopted by each culture, which varies around the world. There are also orthological differences within each of the main writing systems

History of developmental dyslexia

Since Dyslexia was first identified by Oswald Berkhan in 1881, ^[1] and the term 'dyslexia' later coined in 1887 by Rudolf Berlin ^[2], an ophthalmologist practicing in Stuttgart, Germany. ^[3] The history of dyslexia has been the history of Dyslexia research.

Theories of developmental dyslexia

The theories should not be seen as competing, but viewed as theories trying to explain the underlying causes of a similar set of symptoms from a variety of research perspectives and background.

Theories of alexia (acquired dyslexia)

Medical dyslexia research

The medical research of dyslexia began with the examination of post autopsy of brains from people who had dyslexia, which lead to the present day genetic research regarding Dyslexia. The parallel evolution of both the theories of dyslexia and the brain scan technology inspired the current interest in researching the Cognitive Neurological causes of dyslexia.

Controversy

Some disagreement exists as to whether dyslexia does indeed exist as a condition, or whether it simply reflects individual differences among different readers.

The Dyslexia Myth is a documentary that appeared as part of the Dispatches series produced by British broadcaster Channel 4.^[4] First aired in September 2005, it claims to expose myths and misconceptions that surround dyslexia. It argues that the common understanding of dyslexia is not only false but makes it more difficult to provide the reading help that hundreds of thousands of children desperately need. Drawing on years of intensive academic research on both sides of the Atlantic, it challenged the existence of dyslexia as a separate condition, and highlighted the many different forms of reading styles. The documentary focused only on the reading difficulties that people with dyslexia encounter, whereas dyslexia has been argued to include symptoms that extend beyond reading difficulties.

Julian Elliot, an educational psychologist at Durham University in the United Kingdom, disputes the characterization of dyslexia as a medical condition, and believes it should be treated simply as a reading difficulty ^[5]. According to Elliot, "Parents don’t want their child to be considered lazy, thick or stupid. If they get called this medically diagnosed term, dyslexic, then it is a signal to all that it’s not to do with intelligence.”^[6] Elliot believes that children of all levels of intelligence may struggle with learning to read, and that all can be helped by educational strategies appropriate to their needs. He feels that resources are wasted on diagnosis and testing, and favors early intervention programs for all struggling readers.^[7] More recently Julian Elliot has also made reference to the 28 Definitions of Dyslexia which were documented in the Appendices of the National Research and Development Centre for Adult Literacy and Numeracy report on Developmental dyslexia in adults: a research review by Michael Rice with Greg Brooks May 2004. ^{[8] [9]}

John Everatt of the University of Surrey 2007, has suggested that:-

• dyslexic students can be distinguished from other children with low reading achievement by testing geared to assessing their strengths as well as weaknesses
• dyslexic children tend to score significantly better than other children, including non-impaired children, on tests of creativity, spatial memory, and spatial reasoning
• dyslexic children also perform better than other reading-impaired children on tests of vocabulary and listening comprehension
• dyslexic children may be better served by educational intervention which includes strategies geared to their unique strengths in addition to skill remediation

and thus recommends more comprehensive evaluation and targeted interventions. ^[10]
