Neural correlates of post-retrieval monitoring in older adults are preserved under divided attention, but are decoupled from memory performance.

摘要: Abstract Post-retrieval monitoring is associated with engagement of anterior cingulate and dorsolateral prefrontal cortex. Recent fMRI studies reported age-invariant effects in these regions an correlation between memory performance. The present study examined during associative recognition (difference activity elicited by ‘rearranged’ ‘intact’ test pairs) under single dual (tone detection) task conditions young older adults (Ns = 28 per group). It was predicted that, for the only, tasking would attenuate performance weaken their correlation. Consistent this prediction, group imposition secondary led to lower elimination relationship However, size did not differ conditions. findings suggest that decline adults' condition resulted from impaired monitoring, but a different cause also weakened dependence on monitoring.
