q2 i? Only the active group showed a significant training effect on the WM capacity index K over the ten sessions, with significant learning effects only in the earlier phase and a plateau after six days. → Yufeng Ke 2023

Yufeng Ke, Shuang Liu, Long Chen, Xiashuang Wang and Dong Ming. (2023). Lasting enhancements in neural efficiency by multi-session transcranial direct current stimulation during working memory training. npj Science of Learning 8:48. https://doi.org/10.1038/s41539-023-00200-y

q2 · i? · causal · r2

Learning-curve analysis of the capacity index (K = N*d') across ten training sessions using two-way mixed ANOVA found significant training effects and a large-effect-size learning rate across the 10-day training for the active group but not the sham group.

"the active group only showed significant training effects in the earlier phase and reached a capacity plateau after training for 6 days, possibly due to a ceiling effect, while the sham group ’s capacity index exhibited a much slower rising across the training course."
