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 In participants completing both tasks, perceptual and memory metacognitive efficiency correlated positively (r = 0.40, p = 0.02), but this fell to non-significance after removing two outliers (r = 0.25, p = 0.19). → Palmer E.C. 2014

q3 · i3 · associational · r2
Correlational analysis in the subset of 32 subjects who completed both perceptual and memory tasks. The article reports "a positive association between metacognitive efficiencies across domains (r = 0.40, p = 0.02; n = 32)" that "failed to reach significance (r = 0.25, p = 0.19; n = 30)" after outlier removal.
"Consistent with previous findings (McCurdy et al., 2013) we found a positive association between metacognitive efficiencies across domains (r = 0.40, p = 0.02; n = 32; see Fig. 2a.) However, when two memory metacognition outliers were removed (greater than 2 standard deviations beyond the group mean; see Fig. 2a) this relationship failed to reach significance (r = 0.25, p = 0.19; n = 30)."
Discussion¶
Related Claims¶
- Memory metacognitive efficiency correlates with Wechsler Memory Scale scores, but perceptual metacognition does not — related
- Memory metacognitive efficiency shows a non-significant negative relationship with age — related
- Perceptual metacognitive efficiency declines with age in healthy adults aged 18–84, even when task performance is controlled — related
- The age-related decline in perceptual metacognitive efficiency reflects both rising d′ and falling meta-d′ — related
