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? Increases in student-class alpha and low-beta coupling positively predicted math score improvement, with no significant effect for Chinese. → Xiaomeng Xu 2026
q2 i? Coupling with high-performing peers showed only static, subject-specific associations (positive with Chinese, negative with math in the alpha band) and no longitudinal predictive power. → Xiaomeng Xu 2026 (2)

q2 · i? · associational · r2
Dynamic-model comparison using student-class coupling computed from large-scale classroom EEG data. Alpha and low-beta ΔTI positively predicted math improvement, whereas "No significant association was observed between student-class coupling and changes in Chinese scores."
"However, in the case of math, increases in alpha and low-beta ΔTI were positively associated with improvements in academic performance (alpha ΔTI: posterior mean = 0.208, 95%, HPDI [0.021, 0.377]; low -beta ΔTI: posterior mean = 0.217, 95%, HPDI [0.03, 0.412]) ."

q2 · i? · associational · r2
Static-model analysis of student-excellent (top-four-peer) coupling. Delta and alpha TI were positively associated with Chinese performance while alpha TI was negatively associated with math; no significant ΔTI associations were found across the full samples in the dynamic models.
"For student-excellent coupling, TI in the delta and alpha frequency bands was significantly positively associated with Chinese performance (delta TI: posterior mean = 0.107, 95%, HPDI [0.013, 0.199]; alpha TI: posterior mean = 0.113, 95%, HPDI [0.020, 0.199] ), while alpha band TI was significantly negatively associated with math scores (alpha TI: posterior mean = -0.081, 95%, HPDI [-0.158, -0.007])."
