q2 · i? · associational · r2

Correlational analysis (Spearman with Bonferroni correction, α = 0.0166) on word-graph attributes of narratives from 118 healthy adults aged 51–82. The article states RWH's associations with RE and LCC survived age correction but not education correction. No effect sizes are printed for these correlations.

"RWH correlated negatively with RE and positively with LCC, and both remained signi ficant when corrected for age, but lost signi ficance when corrected for education"

Discussion¶

Related Claims¶

• The combination of age, education, and RWH explains 16% of variance in speech graph attributes, with short- and long-range recurrences explained only by their combination and the RWH coefficient compensating for the aging effect — related
• In this sample, age correlated negatively with education and not significantly with RWH, while education correlated positively with RWH (R = 0.58) — related
• Advancing age correlates with more short-range recurrences and less speech connectedness in oral narratives of typical older adults, but these correlations lose significance when corrected for education and reading and writing habits — related
• Education correlates positively with speech connectedness (LCC) in typical older adults, remaining significant when corrected for age but losing significance when corrected for reading and writing habits — related
• School enrollment is associated with narrative connectedness development: the RE-decrease/LCC-LSC-increase dynamic was interrupted by mid-year vacations and resumed after return to school. — related
