Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Topic-medial sentences have lower harmonic centrality than topic-final sentences (p = 0.004), meaning readers transition less often from topic-ending sentences. → Catrysse 2025
q3 i? Topic-final sentences have a lower local clustering coefficient than topic-initial (p = 0.048) and topic-medial (p = 0.008) sentences, indicating less rereading around topic-final sentences. → Catrysse 2025 (2)

q3 · i? · associational · r1
Post hoc comparison from the linear mixed model on harmonic centrality in the 31-reader study; the authors state "topic-medial sentences have a lower harmonic centrality compared to topic-final sentences (p = 0.004)".
"Regarding harmonic centrality, post hoc results indicate that topic-medial sentences have a lower harmonic centrality compared to topic-final sentences (p = 0.004)."

q3 · i? · associational · r2
Post hoc comparisons from the zero-inflated beta generalized mixed model on the local clustering coefficient in the same 31-reader dataset, showing less rereading around topic-final sentences.
"Post hoc tests indicate that topic-final sentences have a lower local clustering coefficient compared to topic-initial (p = 0.048) and topic-medial sentences (p = 0.008)."
Discussion¶
Related Claims¶
- Harmonic centrality and local clustering coefficient show no relation with working memory capacity — related
- Topic-medial sentences have higher strength than topic-initial and topic-final sentences — 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
