While cerebral lateralisation for oral language is well-characterised, cerebral lateralisation for written language is much less well-understood. In this study, Papadopoulou et al. (2022) will use functional transcranial Doppler ultrasonography to assess lateralisation for written language in 7- to 9-year-old children at risk for dyslexia and neurotypical children. They will use tasks that assess efficiency in reading and writing names as well as speed and fluency in writing. The findings of this manuscript will highlight whether children with dyslexia showed atypical lateralisation for language in a written task. In addition, the authors plan to explore the correlation between lateralisation and writing competence. 

 

The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on the edits made to the manuscript, and detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
