1Handwriting performance of children with dyslexia Emma Sumner, Vince Connelly & Anna Barnett
2DYSLEXIASpecific learning difficulty with written language (Rose, 2009)Phonological deficitAffects reading acquisition and spellingEnglish has a deep orthographySpelling requires explicit teachingHigh cognitive cost for individuals with dyslexiaPossible co-occurring motor difficulties (Rose, 2009; Chaix et al., 2007)Slow handwriting?
3THE WRITING PROCESSESBerninger & Swanson (1994)Note. *activates long-term memory during composing and short-term memory during reviewing
4PREVIOUS RESEARCHFor typically developing children, handwriting speed predicts text length and quality (Graham et al., 1997)Inconsistent findings of children with dyslexia having slow handwritingNo 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)
5RESEARCH AIMSTo 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?
6PARTICIPANTS 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 abilityPhonological awarenessReading and non word readingSpellingManual dexterity.Note. There were no differences across the groups for cognitive ability or manual dexterity
7METHOD Alphabet task (1) Writing task (2) Write the alphabet in the correct sequence, as many times as possible in 60 secondsWriting 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).
8ANALYSIS Letters/words per minute Online (writing tablet): Temporal characteristicsExecution speed = distance covered / time spent physically writing
9RESULTS: ALPHABET TASK DyslexicAge-matchedSpelling-abilityNo. of letters30.87 (14.98)37.87 (10.51)17.87 (11.95)Execution speed2.32 (.59)2.23 (.53)1.75 (.47)Pause time (secs)40.41 (5.94)36.75 (5.56)39.45 (4.57)Writing time (secs)19.25 (5.59)22.95 (5.37)20.04 (5.10)Note. No of letters = letters/minute; execution speed = cm/s, excluding pauses.No difference between children with dyslexia and their peers on the letters produced or execution speed measuresThey pause for longer while writing – could explain slightly lower number of letters written.
10RESULTS: FREE WRITING Text characteristics: DyslexicAge-matchedSpelling-abilityAnalytic 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 lowerThey perform at a similar level to the younger SA group
11RESULTS: FREE WRITING Speed of composing text: When actually writing on the page, children with dyslexia can execute handwriting at the same speed as their peersSo, why do they write significantly fewer words per minute?DyslexicAge-matchedSpelling-abilityWords 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)
12RESULTS: FREE WRITINGHere, the children with dyslexia match the younger spelling-ability group
13CONCLUSIONSThe writing tablet provided a detailed analysis of the execution of text:Argues against claims of slow handwriting by children with dyslexiaRather, it shows that the fluency of transcription is frequently interruptedDemonstrates that handwriting is influenced by other processes, such as spellingSuggests that poor spelling is acting as a barrier to productivityFocused interventions on spelling instruction may contribute to resolving the slow rate of composing text.
