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? Guesses about group assignment did not differ across the four conditions, χ2(3,72) = 1.48, p = 0.69. → Limor Shtoots 2024

Limor Shtoots 2024¶
Limor Shtoots, Asher Nadler, Roni Partouche, Dorin Sharir, Aryeh Rothstein, Liran Shati & Daniel A. Levy. (2024). Frontal midline theta transcranial alternating current stimulation enhances early consolidation of episodic memory. npj Science of Learning 9:8. https://doi.org/10.1038/s41539-024-00222-0
q3 · i? · causal · r2
Blinding check after the experiment: participants guessed whether they were in the control or experimental group (e.g., 78% of Theta Frontal and 83% of Sham participants guessed experimental). The chi-square test found no between-group differences in answers. No effect size is printed.
"Our results indicate, via a Chi-square test, that participants in all four group s did not differ in their answers, χ2(3,72) = 1.48,p = 0.69, suggesting that they were blind to the condition to which they were assigned."
