Subclaims¶

q2 i? No significant correlation was observed between students' single-brain attention level and academic performance (r = 0.173, p = .379, n = 28); equivalence was not tested. → Jingjing Chen 2022

Evidence¶

Jingjing Chen 2022¶

Jingjing Chen, Bing Xu & Dan Zhang. (2022). Inter-brain coupling analysis reveals learning-related attention of primary school students. bioRxiv. https://doi.org/10.1101/2022.06.08.495411

q2 · i? · associational · r1

Same classroom EEG observational analysis of 28 grade-3 students; single-brain index was each student's attention level averaged within and across lectures. The article reports "r = 0.173, p = .379, n = 28" with no significant correlation.

"At the same time, no significant correlations were observed between single-brain attention level and their academic performance (Fig.4b, r = 0.173, p = .379, n = 28)."

Discussion¶

Learner Variables¶

• Attention — predictor: learners who differ on it differ in outcomes
