Vincent Connelly & Julie Dockrell Kirsty Walter & Sarah Critten Funded by Leverhulme Trust Psychology & Human Development School of Social Sciences and Law Department of Psychology

5 School of Social Sciences and Law Department of Psychology 5 Example Essays Age 11 SLI

6 School of Social Sciences and Law Department of Psychology 6 Example Essay at age 11 CA Match

7 School of Social Sciences and Law Department of Psychology 7 Text measures No difference in overall scores for the compositions between SLI and LA match. Trends in lexical diversity and total number of words produced.

8 School of Social Sciences and Law Department of Psychology 8 Spelling Total Spelling Errors (SLI=LA)>CA Large amount of spelling errors in texts of SLI and LA group.

10 School of Social Sciences and Law Department of Psychology 10 Pause and Burst Analysis 6

11 School of Social Sciences and Law Department of Psychology 11 Pause & Writing Burst Analysis Number of Writing BurstsNumber of Pauses > 2 sec 12.7 (4.1) 12.6 (3.9) 13.6 (3.2) 17.1 (5.6) 14.6 (5.0) 16.8 (4.6) F(2,101) < 1 F(2,101)=2.5, p>0.05

12 School of Social Sciences and Law Department of Psychology 12 Pause & Writing Burst Analysis Number of words writtenAverage burst length in words Correlation: Number of words written with Av burst length. r(102)=0.80, p< (3.1) 6.7(3.7) 3.9(2.1) 53.4(25.9) 76.1(19.5) 51.8(18.4) F(2,101)=13.7, p<.001F(2,101)=8.5, p<.001 Significant diff in number of words reflects similar difference in average burst length

13 School of Social Sciences and Law Department of Psychology 13 Pause & Writing Burst Analysis No Significant difference in writing time (trend only). No Significant difference in number of bursts No Significant difference in number of pauses Spelling errors (SLI=LA)>CA Total time writing (minus >2 sec pauses) 64.1 (17.6) 73.5 (15.4) 68.1 (14.7) F(2, 101)=3.01, p>0.05

14 School of Social Sciences and Law Department of Psychology 14 Hayes & Chenoweth (2007) Burst length constrained by translator in adults. Not related to copying skills Our results would indicate that the transcriber (as measured through spelling and handwriting) significantly linked to burst length in children.
