Subclaims¶

q3 i? The age–perceptual metacognition relationship remained significant after controlling for Trail Making Test performance (β = −0.0058, p = 0.02), and executive function itself was not associated with metacognition (β = 0.0042, p = 0.26). → Palmer E.C. 2014

General linear model in a subset of 44 participants who completed the Trail Making Test, predicting perceptual meta-d′/d′ from age and set-shifting. The article reports the age effect "remained significant after controlling for changes in executive function (β = −0.0058, p = 0.02)" and no EF association (β = 0.0042, p = 0.26).

"We found that the relationship between age and perceptual metacognitive efficiency remained significant after controlling for changes in executive function (β = −0.0058, p = 0.02), and increased executive function was not associated with better metacognitive efficiency (β = 0.0042, p = 0.26)."

Related Claims¶

• Perceptual metacognitive efficiency declines with age in healthy adults aged 18–84, even when task performance is controlled — a broader claim this one bears on
• Combined with adolescent data, the lifespan profile of perceptual metacognitive efficiency is an inverted-U — related
• The age-related decline in perceptual metacognitive efficiency reflects both rising d′ and falling meta-d′ — related
• Memory metacognitive efficiency shows a non-significant negative relationship with age — related
• Executive function (WCST performance) does not explain age-related differences in world knowledge-based audience design — related
• Memory metacognitive efficiency correlates with Wechsler Memory Scale scores, but perceptual metacognition does not — related
