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? Only the Theta Frontal group displayed a significant off-line gain in free recall performance from the final pre-intervention test to the 2-h post-stimulation test. → Limor Shtoots 2024

Limor Shtoots, Asher Nadler, Roni Partouche, Dorin Sharir, Aryeh Rothstein, Liran Shati & Daniel A. Levy. (2024).

q3 · i? · causal · r2
Repeated-measures experiment in which four groups (n=72 undergraduates) studied object pictures across three study-test cycles, received 20 min tACS/sham, and were retested after a 2-h washout. The article reports that "only the Theta frontal group displayed a significant off-line gain in performance," t(17) = 6.234, p < .001. No standardised effect size is printed for the gain itself, so impact is coded null; the test statistic is reported as printed.
"Another feature of the results presented in Fig.1 is that only the Theta frontal group displayed a significant off-line gain in performance, as confirmed by a paired sample t-test, t(17) = 6.234,p < .001."
Discussion¶
Learner Variables¶
- Long-Term Memory — outcome: instruction changes it
Related Claims¶
- Frontal theta tACS yields strong memory advantages over all other stimulation conditions at 2-hour, 24-hour, and 1-week delayed free recall tests — related
- Post-intervention free recall shows a significant main effect of group favoring frontal theta stimulation, with no group × test interaction — related
- Baseline equivalence across stimulation groups rules out prior memory-ability differences as an explanation for post-intervention effects — related
