Subclaims¶

q2 i2 Gray matter volume in right cerebellar lobule 8 (extending to 7b and adjacent crus) increased from day 1 to day 2 after SRT training, with no group or group × day interaction, in a sample of 17 DD and 18 TD children. → Olivo 2024

q2 · i2 · causal · r1

Longitudinal VBM analysis (CAT12 pipeline) of structural MRI acquired 24 h apart around two in-scanner SRT training sessions in 17 DD and 18 TD children aged 9–13. The article reports increased GMV with "p FWE-corr < 0.001", "t=4 . 6 8", and "C o h e n’s d = 0.605"; no group × day interaction was detected.

"A statistically significant effect of time on GMV was found in the right cerebellar lobule 8, extending to the lobule 7b and adjacent crus, exhibiting increased GMV on day 2 compared with day 1 (p FWE-corr < 0.001; t=4 . 6 8 ;C o h e n’s d = 0.605;"

Discussion¶

Related Claims¶

• General visuomotor skill learning on the SRT task occurs in both DD and TD children with no group difference — related
• SRT training decreases white matter volume in right cerebellar lobule 8 in children regardless of dyslexia status — reports the opposite
