一项发表在最新一期《衰老神经生物学》上的新研究显示，年龄越大，人们可能越不容易认识到自己犯了错。
Researchers from the University of Iowa devised a simple, computerized test to gauge how readily young adults and older adults realize when they've made a mistake.
爱荷华大学的研究人员设计了一个在计算机上进行的简单测试，以评估年轻人和老年人对自己犯了错的意识强弱。
The team recruited 38 younger adults (average age of 22) and 39 older adults (average age of 68) to take a series of tests that involved looking away from a circle appearing in a box on one side of a computer screen.
研究团队招募了38名年轻人(平均年龄22岁)和39名老年人(平均年龄68岁)进行一系列测试，其中包括不去看电脑屏幕一侧的方框里出现的圆圈。
After each failed instance, the participants were asked whether they had made an error.
每次失败后，受试者会被问及他们是否犯了错。
According to the study, younger participants were correct in acknowledging when they had erred 75% of the time.
研究发现，75%的情况下年轻的参与者准确地意识到自己犯了错。
The older test-takers were correct 63% of the time when asked whether they had erred.
当被问及是否犯了错时，年龄较大的受试者的回答在63%的情况下是正确的。
That means in more than one-third of instances, the older participants didn't realize they had made a mistake. Also, older adults were more likely to be adamant that they did not make a mistake.
这意味着在超过1/3的情况下，年龄较大的参与者没有意识到自己犯了错误。而且，老年人更可能坚持认为自己没有犯错。
