q2 i? In a sample of 118 healthy adults, age correlated positively with RE (short-range recurrence) and negatively with connectedness (LCC), and both correlations lost significance when corrected for education and RWH. → Malcorra 2022

q2 · i? · associational · r2

Spearman correlation analysis of word-graph attributes from oral narratives of 118 healthy individuals (mean age 68.71 ± 6.44 years, mean education 9.99 ± 5.73 years). The article reports that "age correlated positively with RE and negatively with connected- ness (LCC)" and that the correlations lost significance after correction. No effect sizes are printed for these correlations.

"Graph analysis revealed that age correlated positively with RE and negatively with connected- ness (LCC). The correlations lost signi ficance when corrected for education and RWH."

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
• 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
• Reading and writing habits correlate negatively with short-range recurrences and positively with speech connectedness (LCC), remaining significant when corrected for age — 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
