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.
q2 i? Across 100 practice sessions, pre-test-to-session correlations qualitatively showed upward trends (e.g., Alpha Span), downward trends (Object Position, Memory Updating, Numerical Comparison), and constant trends, with most results nonsignificant. → Cherry Youn 2022
q2 i? PGS–performance correlations across practice similarly showed upward, downward, and constant trajectories that differed by task and did not appear to reconstitute baseline-performance association patterns. → Cherry Youn 2022 (2)

q2 · i? · associational · r2
Correlation analysis of pre-test scores with performance at every practice session for each task (Fig. 2), including blocks of 10 days and age groups. The article reports it "qualitatively observed three stylized patterns of change" with most results nonsignificant.
"Although most results were nonsignificant, we qualitatively observed three stylized patterns of change in the correlations between pretest scores and practice session performance across the sessions: upward trend, downward trend, and constant."

q2 · i? · associational · r2
Correlations between EAPGS and daily performance across the practice phase (Fig. 3), on residuals independent of baseline age and ancestry PCs. The article reports "three different trajectories of correlations were qualitatively observed: upward trend, downward trend, and constant".
"With residuals of variables that were independent of baseline age and PC, three different trajectories of correlations were qualitatively observed: upward trend, downward trend, and constant."
Discussion¶
Related Claims¶
- Extreme-PGS subgroups show mostly parallel learning trajectories, with task exceptions: for N-Back the low-PGS group learned more and ultimately performed better than the high-PGS group — related
- A polygenic-score study of learning over 100 days of practice in 131 adults was too small to draw meaningful conclusions about genetic effects on baseline performance and learning — related
- Trait-score trajectories over time are inconclusive as learning-curve evidence: one StudyChat trait increases while the significant SWE-Chat traits stay flat — related
