q3 i3 A significant Time × Group interaction on alpha power (η²p = 0.150) reflected higher post-test frontal alpha power in the BCI group. → Hou 2024

q3 · i3 · causal · r2

Single-channel EEG at Fp1 recorded alpha power before and after the 50-minute intervention in the same randomized experiment. The BCI group "had significantly higher alpha power than the sham feedback group on the post-test" (η²p = 0.150, the largest of the three outcomes).

"The results showed a significant interaction effect between Measure (Pre-test & Post-test) and Group (BCI & Sham) on alpha power (F(1,78) = 13.735,p < 0.001, η²p = 0.150). The BCI group had significantly higher alpha power than the sham feedback group on the post-test"
