What is dyslexia? • The word ‘dyslexia’ comes from the Greek (Riddick, Wolfe, & Lumsdon, 2001). dys = impaired lexia = word Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Definition of dyslexia • Dyslexia is a specific learning disability that is neurological in origin. • It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction (International Dyslexia Association, 1996-2007).

Dyslexia: Some key facts • More boys than girls are identified with dyslexia. • Dyslexia is individual Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Causes of dyslexia Acquired dyslexia • Acquired dyslexia occurs when someone who is a good reader loses at least some of that ability due to a brain injury (Hultquist, 2006). Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Causes of dyslexia Developmental dyslexia • It is genetic. • However, dyslexia is not 100 percent inherited (Hultquist, 2006). Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Causes of dyslexia Neurological factor • There is now considerable evidence that there is a neurological basis to dyslexia. • This means that the brain structure and the neural connections needed for processing information may develop differently in dyslexic children (Reid, 2007). • Dyslexic difficulties might be due to either a left-hemisphere deficit or a lag in the maturation of left-hemisphere function for language (Thomson & Watkins, 1998).

Types of dyslexia Phonological dyslexia • People whose reading difficulty is caused by trouble understanding the different phonemes in words (Hultquist, 2006). • People with phonological dyslexia cannot sound out words very well. • Some people also mispronounce words. They might drop some sounds from words. • When people with phonological dyslexia try to spell words, they often add extra sounds, leave out sounds, get sounds in the wrong order, or write down the wrong sounds. Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Types of dyslexia Orthographic dyslexia • People who have trouble remembering what words and letters look like (Hultquist, 2006). • They might have trouble to tell the difference between the letters b, d and p, q. • They might also confuse words that look alike. • People with orthographic processing problems often read very slowly and make many errors when there are a lot of words on a page. They might also skip lines when they read. Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Reading • Reverse, omit or add letters or words • Lose the place when reading • Difficulty with the sequence of the alphabet • Difficulty pronouncing multi-syllabic words • Reading speed is slow and hesitant and often with little expression • Confuse words which have the same or similar sounds Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Writing • Inconsistent writing style • Slow writing speed and reluctance to write a lengthy piece • Unusual writing grip or sitting position Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Handwriting • Poor handwriting • Grip the pen tightly • Dyslexic children are always in a hurry to finish. They also have difficulty copying accurately. • Small, cramped writing is often produced. It may also be the large spiky uncontrolled type. • Messy crossing out or one letter superimposes on another (Pollock, Waller, & Politt, 2004).

Specific difficulties of dyslexia: Memory • Poor short-term/working memory There can be difficulties in remembering lists of information, even short lists, or short instructions (Reid, 2007). Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Memory • Organizational difficulties Children with dyslexia may show poor organization of their timetable and items needed for learning (Reid, 2007). Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Visual perceptual difficulties • A small percentage of dyslexic children report that words on the printed page can appear fuzzy or blurred or jump around even though they seem to have normal vision. Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Specific difficulties of dyslexia: Temporal difficulties • Dyslexic children need more time to learn or process information. Prepared by Ruby Yang, Department of English, The Hong Kong Institute of Education
Other symptoms of dyslexia • The individual child may have no difficulty in communicating his ideas. It is only when faced with communicating via the written word that the deficit is highlighted. • Left/right confusion and directional difficulties • The dyslexic child may well cover up any difficulties by playing the ‘clown’ or attention seeker, or conversely, being the ‘invisible’ child (Thomson & Watkins, 1998).
