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.
q2 i3 In an exploratory FDR-corrected analysis, central fast spindle-slow oscillation coupling strength (ndPAC) correlated significantly with memory retention after feedback-free retrieval practice (r = 0.514), a pattern not observed in restudy or feedback conditions. → Jing Zhang 2025

q2 · i3 · causal · r1
Exploratory correlation analysis of fast spindle-slow oscillation coupling strength (ndPAC) against recall change rate in the nap group's no-feedback retrieval practice condition; the exploratory analysis printed r = 0.514, p(FDR-corrected) = 0.036 for the mean of the C3 and C4 electrodes.
"central fast spindle-slow oscillation coupling strength (ndPAC) (mean of C3 and C4 electrodes) also demonstrated significant correlation with memory re tention after feedback-free retrieval practice ( r = 0.514, p(FDR-corrected) =0.036)"
Discussion¶
Learner Variables¶
- Long-Term Memory — outcome: instruction changes it
