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 i? Neither Chinese nor Math final exam scores correlated significantly with single-brain relative power in any of the four frequency bands. → Jingjing Chen 2023

q2 · i? · associational · r1
Null correlational analysis comparing single-brain EEG features (relative power per band) against final exam scores. The highest observed correlations were small and non-significant: "the highest correlation for Chinese in the theta band: r = −0.180"; equivalence was not tested.
"no signi ficant correlations with the disciplinary final exam scores were found here (Fig. 7b; the highest correlation for Chinese in the theta band: r = −0.180, Pearson 's p = 0.307, permutation p = 0.848, n = 34; Fig. 7d; the highest correlation for Math in the high-beta band: r = −0.141, Pearson 's p = 0.425, permutation p = 0.782, n = 34)."
Discussion¶
Related Claims¶
- Outcome-related inter-brain coupling is frequency-specific: theta for Math and alpha for Chinese, with no significant correlations in the beta bands — related
- Theta-band student-class coupling during Chinese sessions correlates with Math final exam scores, suggesting a discipline-general role for student-class coupling — related
- Alpha-band student-top coupling during Chinese classes is positively correlated with Chinese final exam scores — related
- Theta-band student-class coupling during Math classes is positively correlated with Math final exam scores — related
- Peer-based inter-brain coupling predicts math improvement only via class-average coupling and shows subject-specific static patterns — related
- Static same-wave student-teacher inter-brain coupling is negatively associated with concurrent math performance — related
