q3 i? Reaction times fell significantly from Pre- to both Post-tests in both groups, with no significant group, time, or interaction effects after baseline adjustment. → 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

q3 · i? · causal · r2

Mixed ANCOVAs on RTs of verbal 4- and 6-back tasks at Post1 and Post21, controlling for Pre-test RTs, found insignificant group, time, and group-by-time effects in both tasks; Wilcoxon signed-rank tests confirmed significant RT decreases in both active and sham groups.

"Together, these results demonstrate that participants ’ RTs were not affected by tDCS intervention but decreased in responding to WMT. Moreover, the improvements in the RTs were maintained after three weeks."

Discussion¶

Learner Variables¶

• Processing Speed — outcome: instruction changes it
