q2 i? In the virtual labs and quizzes tasks, the high-beta band showed higher relative PSD in Stage 3 compared to other stages. → Hui Xie 2025 q2 i? The virtual labs task showed a progressive decline in alpha relative PSD across stages, while Stage 1 showed lower alpha in lectures and quizzes. → Hui Xie 2025 (2)

q2 · i? · associational · r1

Whole-brain relative PSD comparisons (Wilcoxon rank sum) across stages and tasks in the semester-long EEG study. The quote states the high-beta finding for "the virtual labs and quizzes tasks" at Stage 3.

"In the virtual labs and quizzes tasks, the high-beta band exhibited higher relative PSD in Stage 3 compared to other stages."

q2 · i? · associational · r1

Same whole-brain alpha-band comparison: Stage 1 alpha was lower in lectures and quizzes, while virtual labs alpha "displayed a progressive decline in alpha band relative PSD as the stages advanced"; the two tasks show opposite alpha trends.

"Stage 1 exhibited lower relative PSD in the alpha band in the online lecture and quizzes tasks compared to subsequent stages. In contrast, the virtual labs task displayed a progressive decline in alpha band relative PSD as the stages advanced."
