q3 i2 A significant Time × Group interaction on self-efficacy (η²p = 0.114) reflected higher post-test self-efficacy in the BCI group. → Hou 2024

Hou, Z., Li, X., Yan, J., & Xu, S. Y. (2024). Enhancing mathematical learning outcomes through a low-cost single-channel BCI system. npj Science of Learning, 9, 65. https://doi.org/10.1038/s41539-024-00277-z

q3 · i2 · causal · r2

Same 80-participant randomized controlled experiment; self-efficacy was measured with an adapted General Self-Efficacy Scale at pre- and post-test. "The BCI group had significantly higher self-efficacy than the sham feedback group on the post-test" (η²p = 0.114).

"The results also showed a significant interaction effect between Mea- sure (Pre-test & Post-test) and Group (BCI & Sham) on self-efficacy (F(1,78) = 10.076,p = 0.002, η²p = 0.114). The BCI group had significantly higher self-efficacy than the sham feedback group on the post-test (pbonf < 0.001)"
