Subclaims¶

q3 i? Psychophysical threshold (mean contrast) and d′ were not correlated with age across the whole sample or within the adolescent group, showing the metacognitive change was not driven by performance changes. → Weil L.G. 2013

q3 · i? · associational · r2

Null correlational analysis in the same 56-participant sample, using a 2-down 1-up staircase to hold accuracy at around 71%. No correlation of contrast or d′ with age supports that "metacognitive ability increased during adolescence and remained stable in adulthood" independently of performance.

"parallel analyses showed that psychophysical threshold (mean contrast) and d′ were not correlated with age across the whole sample (respectively r = −.15, p = .27; r = −.03, p = .80), nor within the adolescent group (respectively r = −.30, p = .13; r = −.19, p = .34)."

Discussion¶

Related Claims¶

• Metacognitive ability improves across adolescence, with a logarithmic age trajectory — related
• Perceptual metacognitive efficiency declines with age in healthy adults aged 18–84, even when task performance is controlled — related
• Metacognitive ability increases with age during adolescence and plateaus in adulthood when task performance is held constant — related
• Metacognitive ability was not correlated with task difficulty or perceptual sensitivity (d′) — a narrower finding that bears on this claim
• Combined with adolescent data, the lifespan profile of perceptual metacognitive efficiency is an inverted-U — related
• Confidence ratings shift toward higher confidence across adolescence and decline in adulthood (Broc) — related
