q2 · i? · associational · r2

Spearman and partial correlation analysis of word-graph measures from the 118-participant oral narrative dataset. The article reports that "Education correlated positively with LCC," that the association survived age correction, and that it lost significance when corrected for RWH. No effect size is printed.

"Education correlated positively with LCC. The correlation remained signi ficant when corrected for age, but lost significance when corrected for 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
• 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
• 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
