q2 i3 Age correlated negatively with education (R = –0.22, p = 0.016), not significantly with RWH (R = –0.15, p = 0.095), and education correlated positively with RWH (R = 0.58, p ≤ 0.001). → Malcorra 2022

Intercorrelations among the social and demographic predictors in the 118-participant dataset. The article prints R = –0.22 (age–education), R = –0.15 (age–RWH, non-significant), and R = 0.58 (education–RWH); the education–RWH correlation magnitude r = 0.58 falls in the |r| ≥ .37 range.

"age correlated negatively with education ( R = –0.22, p = 0.016), but not signi fi-cantly with RWH ( R = –0.15, p = 0.095), and education correlated positively with RWH ( R = 0.58, p ≤ 0.001), as expected."

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