Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 The change in total time from the immediate to the 6-h test was similar for R-PMd, L-PMd, and RP-sham conditions, and only the IP-sham condition improved over that interval. → Taewon Kim 2021

Taewon Kim, John J. Buchanan, Jessica A. Bernard and David L. Wright. (2021). Improving online and offline gain from repetitive practice using anodal tDCS at dorsal premotor cortex. npj Science of Learning 6:31. https://doi.org/10.1038/s41539-021-00109-4
q3 · i3 · causal · r1
A between-subject ANOVA on difference scores between the immediate and 6-h tests showed a significant condition effect with printed effect size ηp² = 0.19; post hoc tests showed only the IP-sham condition improved performance across the 6-h interval.
"Stimulation at PMd during RP however failed to induce time-dependent consolidation that is typical of IP but absent after RP during the initial 6-hr following practice, F(3,60) = 4.82, p < 0.01, ηp 2 = 0.19."
Discussion¶
Related Claims¶
- Anodal tDCS at either left or right PMd during repetitive practice improves online acquisition of novel motor sequences relative to sham conditions — related
- Interleaved practice produces better long-term retention than repetitive practice via offline gains at 6 h and 24 h — related
- Consolidation trajectories differ by schedule: IP-Sham is stable over 6 h then improves after sleep, while RP-Sham forgets in the first 6 h — reports the opposite
- Anodal tDCS at left PMd, but not right PMd, during repetitive practice produces sleep-related offline gain similar to interleaved practice — related
- Early offline gain after interleaved practice is reduced by ctDCS: IP-Sham improves from final training block to the 5-min test while IP-ctDCS remains stable — related
- ctDCS to M1 during interleaved practice does not disrupt subsequent offline consolidation, which proceeds similarly with and without stimulation — related
