q3 i? The alpha NF group's mean absolute error in the interference condition decreased significantly from pretest to posttest 2, with no significant change in the non-interference condition and no change in the sham group. → Zhou 2024

Zhou 2024¶

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 · i? · causal · r2

Color-recall behavioral results from the same randomized sham-controlled experiment. Mean absolute error fell from pretest (M = 28.91) to posttest 2 (M = 24.42); "For the non-interference condition in the alpha NF group, Friedman’s rank test did not show significance (χ2 2ðÞ ¼ 3:11; p ¼ 0:211)".

"Friedman’s rank test showed significance in the interference condition in the alpha NF group ðχ2 2ðÞ ¼ 16; p <0 :001Þ"
