What is dyslexia?
One definition, well known and highly cited (Tunmer
& Greaney, 2010), is that dyslexia:
1. Is a persistent reading and writing difficulty
2. Happens to a normally developing student
3. Happens despite effective instruction
4. Happens because of huge difficulties in decoding words by sound

Should we use the term dyslexia?
Arguments against dyslexia: • Labels are not helpful – stigmatises the student • There is nothing special about dyslexia- we give the same reading
instruction to dyslexic pupils as for ordinary reading difficulties • It is a way for middle class parents to get priority for their children, e.g., in
New Zealand just 17 pupils in decile one schools received special assessment conditions (SACs) for external NCEA exams in 2014. Just under 1300 pupils in decile 10 schools received help.
Arguments for • Some parents say that the label is a “relief” • The simple view of reading and writing says that you can distinguish
dyslexia – it is a special category • Middle class parents are more successful at getting help but that is
because we make it hard for poor parents to get help, by insisting on expensive psychologist reports

Myths about dyslexia
• Dyslexia is reading words backwards – but not peculiar to dyslexia • Dyslexia is related to intelligence – many studies have found that IQ is not
the best predictor of reading difficulties • Dyslexia is a different learning style – most people think they are visual or
auditory or kinaesthetic learners but no evidence to show this • Dyslexia is a boy problem – but this is because boys are worse behaved
and this seems to draw them into remedial reading • Dyslexia will go away with time – it seems to be the opposite – it persists
over a long time • Dyslexia is a visual processing problem – but it does not respond to visual
training • Dyslexia is a balance problem – research evidence has been criticised • Dyslexia is helped with coloured plastic overlays or special glasses – but
studies have found no effect

Dyslexia, family, and the school
• Students: feel different, low self-esteem, “I felt I was the most stupid in the class” “They treat you like a kid” “Embarrassing and humiliating”
• Teachers: “it’s one of those things conjured up by pushy parents” “children who are either too lazy or haven’t got the brains”
• Dyslexia friendly classroom – where the teacher genuinely wants to help out
• Family - These students are average or above in oral language so it comes as a surprise to their family that they struggle to read/write – often from middle class homes, successful parents

Reading Difficulties The simple view describes ‘the reader”
And 3 types of reading difficulties
Three types of reading difficulties
Problems with decoding (dyslexia)
Problems with Listening comprehension (hyperlexia)
Problems with decoding and listening (mixed)

William’s story …
Articulate, good vocabulary …
entered school with enthusiasm.
His year 1 and 2 teachers indicated to his parents that he would do well at school and that his reading would soon ‘take off’.
By year 3 he was aware something was amiss. His parents were concerned because he was not making age-appropriate progress in reading and spelling.
His poor reading and spelling skills were beginning to impact on his self-esteem and self-worth. His
enthusiasm for school disappeared. 20

William … After three years of schooling undoubtedly one of the highest pupils in oral language in the lower SES, 250-300 pupil school, William was reading and spelling well below age level.
William’s school: had few [no] answers for his poor progress.
William’s parents: at a loss

Do dyslexic students read text differently? Not many studies have looked at this
• Thomson (1978) compared dyslexic 10-year-olds with good readers of the same age
• Method – N=40 students (20 dyslexic, 20 good readers of same age); children read passages from Neale Analysis of Reading Ability; their miscues were classified
• It could be that the dyslexic poor reader will make more meaningful errors than the non-dyslexic poor reader because they are able to use their language skills to make better guesses from story context about words they do not know
• If they did do this then it would mean they are a different category or poor reader. Their guessing skills might actually work against them if they relied on this rather than trying to learn how to decode – which might explain why they make good progress when they learn decoding skill. The Thomson study looked at this question.

The two groups – matched for age, sex, intelligence (IQ), socioeconomic status
Dyslexic Group Good reader group
Age 10.5 10.10
Reading age 8.2 11.8
Spelling age 7.7 11.10
IQ (non verbal) 11.7 11.8

Thomson Discussion
1. Dyslexic group’s reading comprehension level was at their age level in the Thomson study – even though their oral reading and speed was much lower than their chronological age. To have normal reading comprehension for their age is in itself is different to other poor readers.
2. Results: In terms of surface structure, dyslexic group made more graphic and phonemic miscues than did the good reader group – but made similar syntactic and semantic miscues.
3. The Thomson results indicated that the difference between the good readers and dyslexic readers was in reading accuracy, not in ability to use context clues. But we are doing more research on this - to compare dyslexic readers with younger normally developing readers of the same reading age and with younger non-dyslexic poor readers. If their miscues turn out to be different, then dyslexia may be a different category of poor reader.

So the jury is still out: Do dyslexic students make different kinds of reading errors to other poor readers
or younger normally developing readers?
• We still don’t have the answer to that question • Thomson’s 1978 research compared dyslexic 10-year-olds
with normal readers in terms of their reading miscues • But to answer our question, we need to compare the
dyslexic group with another group of matched poor readers who are not dyslexic, and also use a reading-age match with younger, average readers
• Comparing the dyslexic poor reader group with a group of good readers does not answer the question
• Dyslexics’ reading errors may be different to other poor readers – we need to do more research on this
• If they are different, then we probably need to keep the label, “dyslexia”

“This correction is an embarrassing one. In the heading of our article on High School students going to Peru we spelt the country’s name as ‘Puru’. We have checked the atlas just in case there is such a country but regrettably there is not.”
