Subclaims¶

q3 i? P3 peak amplitude decreased from 2.68 μV to 2.19 μV and peak-to-peak P3N1 amplitude decreased by ~1 μV in BMM sessions, interpreted as more economical neural recruitment. → Huang 2026 q3 i2 Channel-level ANCOVA on the PP amplitude index showed significant group effects at P4 (η2 = 0.100) and Oz (η2 = 0.084). → Huang 2026 (2)

q3 · i? · causal · r1

ERP amplitude analysis of grand-average waveforms in the BMM group; N1 magnitude also decreased and "the composite peak-to-peak P3N1 amplitude (PP) decreased by ~1 μV in BMM sessions". Control participants showed a contrasting pattern with little net change.

"At the grand-average level, P3 peak amplitude decreased from 2.68 μV at pre-test to 2.19 μV at post-test (a ~ 0.48 μV reduction), as shown in Fig. 4D–F."

q3 · i2 · causal · r2

Channel-level ANCOVA on the peak-to-peak P3N1 amplitude index over posterior electrodes, controlling pre-test values; "significant effects were observed at P4, F = 6.015, p = 0.017, η2 = 0.100, and Oz".

"Specifically, significant effects were observed at P4, F = 6.015, p = 0.017, η2 = 0.100, and Oz, F = 4.948, p = 0.030, η2 =0 . 0 8 4 ( T a b l e4)."
