Subclaims¶

q3 i3 A significant Group × Block interaction showed alpha changes across blocks differed between the NF and sham groups, with alpha increased in blocks 3–5 versus block 1 in the NF group only (ηp2 = 0.273). → Zhou 2024 q3 i? Neither the Group × Day interaction nor the Group main effect was significant for alpha across sessions, indicating unsuccessful long-term NF learning. → Zhou 2024 (2)

Zhou, W., Nan, W., Xiong, K., & Ku, Y. (2024). Alpha neurofeedback training improves visual working memory in healthy individuals. npj Science of Learning 9, 32. https://doi.org/10.1038/s41539-024-00242-w

q3 · i3 · causal · r2

Within-session alpha amplitude analysis (2×5 mixed-design repeated-measures ANOVA on mean alpha per block) during NF training; the interaction printed ηp2 = 0.273. "Further analysis found a significant increase in alpha amplitude in the last three blocks (blocks 3 to 5) compared to Block 1 in the NF group, which was not the case in the sham control group."

"Group × Block has a significant interaction (F (4,35) = 3.29, p = 0.022, ηp 2 = 0.273), indicating that alpha changes across blocks significantly differed between the NF training group and the sham control group"

q3 · i? · causal · r2

Across-session alpha analysis (2×5 mixed-design repeated-measures ANOVA on mean alpha per session over five days); the day main effect was only marginally significant (F(4,35) = 2.54, p = 0.057, ηp2 = 0.225).

"In contrast, neither Group× Day interaction (F (4,35) = 0.22, p = 0.924) nor the main effect of group (F (1,38) = 1.21,p =0 . 2 7 8 )s h o w e d significance"
