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 i3 WM capacity declines with age (r = -.77, p < .0001). → Sung JE 2015

Sung JE (2015) Age-Related Changes in Sentence Production Abilities and Their Relation to Working-Memory Capacity: Evidence from a Verb-Final Language. PLoS ONE 10(4): e0119424. https://doi.org/10.1371/journal.pone.0119424
q3 · i3 · associational · r2
Pearson correlation between the composite WM index and age in the 60-participant cross-sectional sample (ages 21–86). The article prints "r = -.77, p < .0001", a strong negative correlation.
"WM was significantly and negatively correlated with age ( r = -.77, p < .0001)."

- VSTM performance declines with advancing adult age in raw error, item capacity, precision, and misbinding, even after adjusting for sensorimotor performance — related
- After controlling for age, WM correlates significantly only with the most demanding condition (priming task, noncanonical word order) — related
- Working-memory capacity correlates positively with accuracy on all four sentence-production conditions — related
- Verbal memory performance declines with age in the full sample, significantly at the one-week delay — related

- The syntactic-priming task with noncanonical word order is the best single predictor of age among the four sentence-production conditions — related
