Subclaims¶

q3 i? Raw error magnitude significantly increased with age and K, precision, and misbinding all worsened with age across the adult life span. → Daniel J. Mitchell 2018 q3 i? Age-related declines remained for all memory measures after regressing out perceptual control (sensorimotor) performance. → Daniel J. Mitchell 2018 (2)

q3 · i? · associational · r3

Cross-sectional analysis of the Cam-CAN population-based sample of 649 participants aged 18 to 89 on a continuous color-report VSTM task. The article reports statistically significant age-related worsening of raw error and K with no printed effect size in this passage.

"Raw error magnitude significantly increased with age on average (see Figure 2e), and at all memory loads (see Figure 2a). K at each memory load reduced with age (see Figure 2b), but the relationship was weaker at lower loads due to a ceiling effect."

q3 · i? · associational · r3

Correlational analysis in which precision and K estimates from a no-memory perceptual control block were regressed out of every VSTM measure before recomputing age correlations. Declines persisted for all memory measures, indicating they are not attributable to poorer color perception or motor control.

"Importantly, age-related declines remained for all memory measures (see Figures 2i through 2l)."

Discussion¶

Related Claims¶

• Blocked-format span declines after age 20 but mixed-format span does not, implicating proactive interference in aging declines — related
• Consistent visual context between sample and probe boosts all measures of VSTM performance, and the benefit is preserved across the adult age range — 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
• Metacognitive awareness of VSTM performance becomes less accurate with age but remains well above chance across the adult life span — related
• At low memory loads, older adults report less uncertainty than younger adults despite making larger errors, suggesting an overconfidence bias — related
• WM capacity is significantly and negatively correlated with age in Korean adults — related
• Verbal memory performance declines with age in the full sample, significantly at the one-week delay — related
• Poorer useful field of view performance in older adults predicts motor vehicle collision risk and difficulties in everyday visual tasks, even after adjustment for sensory and cognitive impairment — related
