SummarySummary

1. Dyslexia – what is it?

2. Theoretical rationale behind the test sections.

3. Results from Pilot.

4. Applications & Limitations of test – what can it be used for?

The TaskThe TaskTo produce a screener that is:Accurate. Short, making holistic statements.Suggests definite courses of action.

Purpose of TestPurpose of Test Part of a new reading test for

MidYIS intended to assess various levels of literacy ability:

Phonological & phonic skills. Providing information useful in deciding who may need specialist assessment for dyslexia, etc.

Vocabulary – picture and sound.Comprehension - component skills, e.g.

inference making.

Advantages of the TestAdvantages of the Test

Fits within a lesson.Short sub-tests and partly

adaptive, designed to minimize stress.

Gives an overall estimate of the likelihood of having a literacy difficulty such as dyslexia. But does NOT diagnose it!

Advantages of the Test, cont’dAdvantages of the Test, cont’d

Suggests the type of deficit, so can inform future strategies.

Synergies with the main MidYIS test – offers an holistic picture of the student.

What is Dyslexia?

The review’s working definition:

1. A learning difficulty that primarily affects the skills involved in accurate

and fluent word reading and spelling.

What is Dyslexia?What is Dyslexia?

2. Characteristic difficulties in:phonological awareness verbal memory verbal processing speed.

What is Dyslexia?What is Dyslexia?

3. Occurs across the range of intellectual abilities.

4. A continuum, not a distinct category.

5. No clear cut-off points.

Rationale Behind the Test Rationale Behind the Test SectionsSections

Test phonological and phonic skills.Phonology- word sounds.Phonological processing deficit in

dyslexia.Phonic problems – relating graphemes

(letters & letter groups) to the corresponding sounds (phonemes).

Tests of Phonology- Made-up word (nonword) reading,

adaptive test.‘Sounds’ test – identifying sounds

in words.Phonological Short Term Memory-

forward & backward digit span.

Design of Sub TestsDesign of Sub Tests

‘Nonword reading’ and ‘Sounds’ – adaptive, to:

match difficulty of items to student ability;

Reduce assessment load and time.

PhonicsPhonicsNonword reading- relating graphemes

to phonemes.‘Sounds’- sounds to letters, as in

spelling.Pseudohomophone test- made-up

words (pseudowords) that sound like real words, e.g. phocks = fox. Also, test of phonology.

Pseudohomophone TestPseudohomophone Test Pseudo = made-up word Homophone = sounds like Requires many visual and auditory skills:

e.g. reading ‘phocks’

grapheme separation: ‘ph’ ‘o’ ‘ck’ ‘s’

grapheme-phoneme conversion:

‘ph’> /f/ ‘o’> /o/ ‘ck’ > /k/ ‘s’> /s/

Phoneme blending:

/f/ /o/ /k/ /s/

Then..

Pseudohomophone Test cont.Pseudohomophone Test cont.

Match sound package of blended phonemes with items in known sound vocabulary.

/f/ + /o/ + /k/ + /s/ = ‘fox’

Added difficulty – word search format.

Visual search problems in dyslexia.

Choose 5 out of 16 on each of 5 screens.

GuessingGuessing

Nonword reading: 1 in 4 chance. Forced choice multiple choice.

‘Sounds’: 1 in 4 chance. Forced choice multiple choice.

Word Search (pseudohomophones): 5 in 16 chance. Can move on without answering.

‘Lyrebird’ Test – an adaptation of a spoken digit span test for computer.

Lack of visual distraction- black screen with fixation spot.

Response entered on screen.Max number of digits = 8, to reduce

assessment load and time.

Design of Sub TestsDesign of Sub Tests

MemoryMemory

Problems with phonological STM common in dyslexia. Order problems- e.g. telephone numbers.

Backward digit span –measure of working memory.

Short backward digit span often found in dyslexia.

Schools who returned both test files and validation data (n=808):22 were Independent (all England) 2 were International (1 Vietnam, 1 Qatar) 6 were State schools (3 England, 3 Northern Ireland).Schools who only returned test files:14 Independent (all England) 8 State (7 England, 1 Wales)

ResultsResultsGenetic program, ‘Eureqa’ (Schmidt &

Lipson, e2009).Suggested 2 different cognitive profiles.NVR-strong group, n= 66, distinct from NVR-

strong typicals by relationship between nonword reading and Word Search.

NVR-weak group, with phonologicsl profile indistinct from NVR-weak typicals.

Phonic ProfilesPhonic ProfilesPhonics = relationship between graphemes (letters/letter groups) and phonemes (the sounds associated with those graphemes).

Asynchrony hypothesis ( e.g. Breznitz, 2002; King, 2009; King, Wood & Faulkner, 2008). Lack of auditory-visual integration in dyslexia.

Vector reflecting relationship between phonological and visual abilities / speed of processing.

Specific strategies suggested Specific strategies suggested by Type from Testby Type from Test

Vocabulary stronger than NVR type:Visuo-spatial memory or cognitive

manipulation problem?Practising mental rotations and

reflections may help both the NVR and reading skills?

Memory visualisations?

Strategies for NVR-Strong Strategies for NVR-Strong DyslexicsDyslexics

Poor reverse digit span cf NVR-type typical students implies that training in improving working memory may help.

BUT their memory skills are commensurate with typical readers of the strong vocabulary type!

Phonology? Subject choices- eg languages.

Uses & Limitations of the TestUses & Limitations of the TestAudit of phonological abilities of a

cohort.Shows strengths & weaknesses.Does not diagnose dyslexia.Cannot identify ‘recovered’ dyslexic

readers.Shows marked phonological / phonic

difficulties.
