Output monitoring refers to memory for whether an intended action has been completed. Failures in output monitoring can lead to action repetitions or action omissions. Output monitoring is difficult for both younger and older adults, but few studies have examined age differences in output monitoring. Two experiments using a picture-based prospective memory task with an output-monitoring component were conducted to investigate the role of increased contextual detail and pre-exposure on output-monitoring accuracy in younger and older adults. Across the two experimental manipulations older adults demonstrated less accurate output monitoring by primarily committing errors of repetition. Pre-exposure to targets resulted in worse output-monitoring accuracy for both younger and older adults.
输出监控是指对一个预期行为是否已经完成的记忆。输出监控的失败可能导致行为重复或遗漏。输出监控对年轻人和老年人来说都很困难，但很少有研究探讨输出监控中的年龄差异。本研究使用基于图片的前瞻性记忆任务和输出监控组件进行了两项实验，以调查在年轻人和老年人中，增加上下文细节和预先暴露对输出监控准确性的作用。在这两个实验操作中，老年人主要通过重复错误来表现出较低的输出监控准确性。对目标的预先暴露会导致年轻人和老年人的输出监控准确性都变差。
