提取后监测与前扣带回和背外侧前额叶皮质的参与有关。最近的功能磁共振成像研究报告在这些地区的年龄不变的监测效果和这些效果和记忆性能之间的年龄不变的相关性。本研究探讨了监测效果在联想识别（活动引起的差异“重新安排”和“完整”的测试对）在单一和双重（音调检测）的任务条件下，在年轻人和老年人（NS = 28每组）。据预测，只有老年人，双重任务会削弱记忆性能和监控效果，削弱他们的相关性。与这一预测相一致，在老年组强加的次要任务导致较低的记忆性能和消除监测效果和性能之间的关系。然而，影响的大小并没有不同的单和双任务条件。研究结果表明，老年人在双重任务条件下的记忆表现下降不是由于监测受损，而是由于不同的原因，也削弱了表现对监测的依赖。
Post-retrieval monitoring is associated with engagement of anterior cingulate and dorsolateral prefrontal cortex. Recent fMRI studies reported age-invariant monitoring effects in these regions and an age-invariant correlation between these effects and memory performance. The present study examined monitoring effects during associative recognition (difference in activity elicited by ‘rearranged’ and ‘intact’ test pairs) under single and dual (tone detection) task conditions in young and older adults (Ns = 28 per group). It was predicted that, for the older adults only, dual tasking would attenuate memory performance and monitoring effects and weaken their correlation. Consistent with this prediction, in the older group imposition of the secondary task led to lower memory performance and elimination of the relationship between monitoring effects and performance. However, the size of the effects did not differ between single and dual task conditions. The findings suggest that the decline in older adults’ memory performance in the dual task condition resulted not from impaired monitoring, but from a different cause that also weakened the dependence of performance on monitoring.
