Subclaims¶

q3 i? Reported uncertainty declined with age at loads 1 and 2 (load 1: r = -0.14, p < .001; load 2: r = -0.13, p < .01) but not at loads 3 through 4. → Daniel J. Mitchell 2018

q3 · i? · associational · r3

Correlation of mean confidence-interval width with age per memory load in the Cam-CAN sample. The article interprets this as older adults being more confident of their judgments than younger adults at low loads despite making larger errors, a metacognitive bias consistent with reported age-related increases in overconfidence.

"Reported uncertainty declined slightly with age, but only at low memory loads (load 1: r = −0.14, p < .001; load 2: r = −0.13, p < .01; loads 3 through 4: p > .1)."

Discussion¶

Related Claims¶

• Metacognitive awareness of VSTM performance becomes less accurate with age but remains well above chance across the adult life span — related
• Better metacognitive awareness of trial-to-trial VSTM performance is associated with lower error, higher precision, and fewer misbinding errors, but not with item capacity, and this association is invariant across age — related
• VSTM performance declines with advancing adult age in raw error, item capacity, precision, and misbinding, even after adjusting for sensorimotor performance — related
• Older age groups overestimate their mathematical and reading competence more than younger age groups, but this may reflect performance differences — related
• Metacognitive monitoring declines under high working memory load, suggesting functional dependence of MC on WM — related
• Poor mathematics performers are less intrinsically motivated, less metacognitively accurate, and overestimate their performances more often than well-performing peers in all grades — related
• Grade 4 children can metacognitively monitor their working memory performance, tending to be over-confident as task difficulty increases — related
