在两个实验中，年轻人和老年人进行了60分钟的认知警觉测试，其中记忆需求等同于数字广度的个体差异。在第一个实验中，评估了金钱奖励对被试表现的影响。持续的注意力的年轻人和老年人都支付他们的参与没有什么不同，它并没有下降在守夜，但年轻人谁没有支付他们的参与证明了一个显着的警惕性下降。在第二个实验中，对记忆的要求增加了，并且没有提到参与的金钱奖励。年轻人的注意力迅速下降，但老年人的注意力没有证据表明警惕性下降。被试的持续注意力可以从任务特征、内在动机和外在动机两个方面来解释。
In two experiments, young and older adults performed 60-min cognitive vigilance tests in which memory demands were equated for individual differences in digit span. In the first experiment, the effects of monetary reward on subjects' performance were assessed. The sustained attention of young and older adults who were both paid for their participation did not differ, and it did not decline during the vigil, but young adults who were not paid for their participation evidenced a significant vigilance decrement. In the second experiment, memory demands were increased and there was no mention of monetary reward for participation. The attention of young adults declined rapidly, but that of older adults did not evidence a vigilance decrement. Subjects' sustained attention is explained in terms of task characteristics and intrinsic and extrinsic motivational factors.
