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 Immediately after practice, total time was significantly lower for both left- and right-PMd stimulation groups than for the RP-sham and IP-sham groups, with no difference between the two stimulation sites. → Taewon Kim 2021

q3 · i3 · causal · r2
In the four-condition experiment (N=64 right-handed undergraduates), a 4 (Condition) × 2 (Test: BASE, IMM) mixed ANOVA on total time showed the stimulation groups significantly faster than sham at the immediate test, with printed effect size ηp² = 0.36. Post hoc means: L-PMd 1556 ms, R-PMd 1551 ms, RP-Sham 1909 ms, IP-Sham 1949 ms.
"Immediately after practice, TT was similar for individuals exposed to anodal tDCS at either right or left PMd during RP which in turn was signi ficantly lower than TT for individuals in the sham conditions, F(3,60) = 11.01, p < 0.001, ηp 2 = 0.36."
Discussion¶
Related Claims¶
- During training, real stimulation at either PMd yields superior performance on almost all blocks, and RP-sham reduces total time faster than IP-sham — related
- Anodal tDCS at left PMd, but not right PMd, during repetitive practice produces sleep-related offline gain similar to interleaved practice — related
- Stimulation at PMd during repetitive practice fails to induce the early (6-h) time-dependent consolidation typical of interleaved practice — related
- Repetitive practice yields faster online acquisition than interleaved practice for motor sequence learning — related
- Forgetting after repetitive practice is extremely rapid, appearing within roughly 3–5 minutes after training ends — related
