绩效监测是执行功能的一个核心组成部分，已被发现在老年人中发生了变化。具体地说，老年人表现出错误相关负波(Ne/ERN)的幅度较小，而正确相关负波(NC/CRN)的幅度增加，并且缺乏对刺激-反应兼容性的调整。本研究使用具有两个难度水平的视觉大小辨别任务，进一步考察了与年龄相关的适应实际任务要求的变化。老年人表现出谨慎的反应策略，反应较慢，但比年轻人更准确。这两个年龄组都表现出错误后的减速。在困难的情况下，老年人对错误的误解更大。与老年人相比，年轻人的NE/ERN波幅降低，NC/CRN波幅由易到难依次升高。这可能表明，在较年长的年龄组中，对任务难度的适应程度有所降低。研究结果表明，年龄对错误的有意识知觉和自动绩效监控对不断变化的任务要求的适应性均受到年龄的影响。
Performance monitoring which is a core component of the executive functions has been found to be altered in older adults. Specifically, older adults showed smaller amplitudes of the error-related negativity (Ne/ERN) but increased amplitudes of the correct-related negativity (Nc/CRN), and a lack of adjustment to stimulus-response compatibility. The present study used a visual size discrimination task with two difficulty levels to further examine age-related alterations of the adaptation to actual task demands. Older adults showed a cautious response strategy with slower but more accurate responses than younger adults. Both age groups showed post-error slowing. Misperception of errors in the difficult condition was larger in older adults. In contrast to older adults, Ne/ERN amplitudes decreased and Nc/CRN amplitudes increased from the easy to the difficult condition in younger adults. This may indicate that adjustment to task difficulty was reduced in the older age group. It is concluded that conscious perception of errors and adaptation of the automatic performance monitoring to changing task demands are affected by age.
