1 Handwriting performance of children with dyslexia Emma Sumner, Vince Connelly & Anna Barnett

2 DYSLEXIA  Specific learning difficulty with written language (Rose, 2009)  Phonological deficit  Affects reading acquisition and spelling  English has a deep orthography  Spelling requires explicit teaching  High cognitive cost for individuals with dyslexia  Possible co-occurring motor difficulties (Rose, 2009; Chaix et al., 2007)  Slow handwriting?

3 THE WRITING PROCESSES Note. *activates long-term memory during composing and short-term memory during reviewing Berninger & Swanson (1994)

4 PREVIOUS RESEARCH  For typically developing children, handwriting speed predicts text length and quality (Graham et al., 1997)  Inconsistent findings of children with dyslexia having slow handwriting  No different to peers on copying tasks (Martlew, 1997)  1SD below the mean on the alphabet task (Berninger et al., 2008)  Spelling ability predicts compositional skills of children with dyslexia (Berninger et al., 2008)

5 RESEARCH AIMS To investigate handwriting execution using a writing tablet:  Do children with dyslexia demonstrate a slower handwriting speed than their peers?  Are they slower at composing written text?  Do children with dyslexia pause frequently while writing?

6 PARTICIPANTS  31 children with dyslexia (mean age 9 years)  31 typically developing age controls (9 years old)  31 spelling-ability matches (6 years old)  Selection measures:  Cognitive ability  Phonological awareness  Reading and non word reading  Spelling  Manual dexterity. Note. There were no differences across the groups for cognitive ability or manual dexterity

7 METHOD Alphabet task (1) Write the alphabet in the correct sequence, as many times as possible in 60 seconds Writing task (2) Narrative: ‘Design a place for you to live....describe how you want your ideal home to look’ (1) Detailed Assessment of Speed of Handwriting (Barnett et al., 20007); (2) Wechsler Objective Language Dimensions (Rust, 1997).

8 ANALYSIS  Letters/words per minute  Online (writing tablet):  Temporal characteristics  Execution speed = distance covered / time spent physically writing

9 RESULTS: ALPHABET TASK  No difference between children with dyslexia and their peers on the letters produced or execution speed measures  They pause for longer while writing – could explain slightly lower number of letters written.

No of letters = letters/minute; execution speed = cm/s, excluding pauses.

10 RESULTS: FREE WRITING Text characteristics: DyslexicAge-matchedSpelling-ability Analytic score (raw) 8.61 (2.72) 13.68 (3.20) 7.52 (1.59) Spelling errors15.39 (9.01) 4.87 (4.08) 12.56 (8.78) % of text21%4%39%  In comparison to their peers, the quality of the writing produced by children with dyslexia is much lower  They perform at a similar level to the younger SA group

11 RESULTS: FREE WRITING Speed of composing text:  When actually writing on the page, children with dyslexia can execute handwriting at the same speed as their peers  So, why do they write significantly fewer words per minute? DyslexicAge-matchedSpelling-ability Words per min8.19 (3.34) 11.48 (3.56) 5.17 (2.38) Execution speed (cm/s) 2.11 (.69) 2.19 (.64) 1.59 (.44)

12 RESULTS: FREE WRITING  Here, the children with dyslexia match the younger spelling-ability group

13 CONCLUSIONS  The writing tablet provided a detailed analysis of the execution of text:  Argues against claims of slow handwriting by children with dyslexia  Rather, it shows that the fluency of transcription is frequently interrupted  Demonstrates that handwriting is influenced by other processes, such as spelling  Suggests that poor spelling is acting as a barrier to productivity  Focused interventions on spelling instruction may contribute to resolving the slow rate of composing text.

14 THANK YOU FOR LISTENING Special thanks to Vince Connelly, Anna Barnett, The Waterloo Foundation, and all the children that participated in this research.
