Subclaims¶

q2 i? Global efficiency was higher in Stage 1 than the other two stages where tested, indicating decreasing overall network connectivity as the learning stage progresses. → Hui Xie 2025 q2 i? Local efficiency varied significantly across stages in each task. → Hui Xie 2025 (2)

q2 · i? · associational · r1

Graph-theoretic analysis of PLI-based functional connectivity in the semester-long EEG study. Wilcoxon tests found global efficiency differences only between lecture Stage 1 vs 3 and quiz Stage 1 vs 2; "the global efficiency of Stage 1 w a sh i g h e rt h a nt h eo t h e rt w os t a g e s."

"The global efficiency of Stage 1 w a sh i g h e rt h a nt h eo t h e rt w os t a g e s .T h i si n d i c a t e st h a tt h ee f f e c t i v e n e s so f the overall network connectivity decreases as the learning stage progresses, and information propagation between different regions gradually slows down."

q2 · i? · associational · r1

Local efficiency comparisons across the three stages of each task (Table 1) reached significance, with median values, p values, and power reported per pairwise comparison; the authors state "the local efficiency between different stages in each task varies significantly."

"In contrast, the local efficiency between different stages in each task varies significantly, as shown in Table1. This variation may imply that the local network structure of each stagechanges considerably."
