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 i? Stroop accuracy and reaction time show no significant tDCS group effects. → Xie 2024

Evidence

Xie, C., Zhang, S., Qiao, X., & Hao, N. (2024). Transcranial direct current stimulation targeting the bilateral IFG alters cognitive processes during creative ideation. npj Science of Learning, 9, 75. https://doi.org/10.1038/s41539-024-00285-z

q3 · i? · causal · r2

One-way ANOVAs (adjusted for gender) on Stroop performance in the tDCS experiment; the quote reports the null group effects with ηp 2 = 0.04 for accuracy and ηp 2 < 0.01 for reaction time, ruling out executive-function changes as the source of the CRA findings.

"the tDCS applied in the present study showed neither a significant effect on accuracy on the Stroop task (F2,76 =1 . 4 1 ,p = 0.25, ηp 2 = 0.04) nor reaction times on that task"
