q2 · i? · associational · r2

Spectral analysis of trend-adjusted aggregated time series from the daily diary study. The article reports "a periodicity with a frequency of seven" in both time series, with lecture time peaking on Tuesdays and approaching zero on weekends, and independent study lowest on Saturdays.

"Analysis for both lecture- and independent study time investments shows a periodicity with a frequency of seven, which indicates that a weekly rhythm is observable in both time series."

Discussion¶

Related Claims¶

• Over a full term, aggregated lecture time decreases linearly while independent study time follows a negative quadratic trajectory, rising until the end of the lecture period and then declining — related
• Emotional variability in L2 learning episodes is primarily intraindividual (62–68%), with modest lag-1 inertia (r ≈ .17–.19) and weak long-term trends or weekly cycles — related
• Using breaks between lectures for independent study is an independent positive predictor of daily study satisfaction beyond overall time investment — related
