Subclaims¶

q2 i? TD children consistently outperformed DD children on implicit sequence learning at both time-points, while the groups did not differ in ISL change from day 1 to day 2 (p = 0.390). → Olivo 2024

Evidence¶

Olivo 2024¶

Olivo, G., Persson, J. & Hedenius, M. (2024). Exploring brain plasticity in developmental dyslexia through implicit sequence learning. npj Science of Learning, 9:37. https://doi.org/10.1038/s41539-024-00250-w

q2 · i? · causal · r1

Behavioral results reported in the Results section, described in detail in the authors' prior report; Table 1 prints ISL day 1 of 0.06 (DD) versus 0.10 (TD) and day 2 of 0.08 versus 0.13, with the group change comparison reported as p = 0.390.

"Overall, both groups improved on their ISL score with the same pattern; however, TD children consistently performed better than DD at both time-points."

Discussion¶

Related Claims¶

• General visuomotor skill learning on the SRT task occurs in both DD and TD children with no group difference — related
• Group membership moderates the correlation between white matter volume of the left precentral gyrus and implicit sequence learning change, with a negative correlation in TD children but none in DD children — related
• No correlations were detected between short-term GMV or WMV change and changes in implicit sequence learning or general visuomotor skill — related
