Subclaims¶

q3 i? When working memory capacity increases, betweenness centrality decreases (β = −0.709, p = 0.017), suggesting high-WMC readers do not rely on crucial intermediary sentences. → Catrysse 2025

Evidence¶

Catrysse 2025¶

Catrysse, L., van Daal, T., Jarodzka, H., Kaakinen, J. K., Donche, V., & Gijbels, D. (2025). How Eye Read: A Social Network Approach. Educational Psychology Review. https://doi.org/10.1007/s10648-025-10000-y

q3 · i? · associational · r1

Linear mixed-effects model on betweenness centrality from the same 31-reader eye-tracking dataset; the printed fixed effect of WMC was β = −0.709, p = 0.017, with marginal R² = 0.024 and conditional R² = 0.260.

"Betweenness is related to working memory capacity: when working memory capacity increases, betweenness decreases."

Discussion¶

Learner Variables¶

• Working Memory — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Readers with higher working memory capacity make more transitions between sentences (higher strength) — related
• Harmonic centrality and local clustering coefficient show no relation with working memory capacity — related
• Strength is strongly positively correlated with second-pass reading time, while betweenness, harmonic centrality and local clustering coefficient are not related to duration measures — related
• High-WMC readers make more distant regressions within text, suggesting more cross-text integration — related
