q2 i? Inter-brain coupling at low-beta and high-beta bands failed to correlate significantly with final exam scores, whereas theta and alpha bands did. → Jingjing Chen 2023

q2 · i? · associational · r1

Summary correlational analysis across four frequency bands (theta, alpha, low-beta, high-beta) shown in Fig. 5, demonstrating "the frequency-speci ficity" of outcome-related inter-brain couplings; no effect sizes for the null beta-band results are printed.

"Inter-brain coupling in the theta and alpha bands was found to correlate with the final exam scores (as shown above) signi ficantly. In contrast, the inter-brain coupling at the low-beta and high-beta bands failed to reach signi ficance."
