研究顯示 人越老越難認識錯誤

A new study published in the latest issue of Neurobiology of Aging showed that the older people get, the less apt they may be to recognize that they've made an error.
一項發表在最新一期《衰老神經生物學》上的新研究顯示，年齡越大，人們可能越不容易認識到自己犯了錯。

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.
愛荷華大學的研究人員設計了一個在計算機上進行的簡單測試，以評估年輕人和老年人對自己犯了錯的意識強弱。

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.
研究團隊招募了38名年輕人（平均年齡22歲）和39名老年人（平均年齡68歲）進行一系列測試，其中包括不去看電腦屏幕一側的方框裏出現的圓圈。

After each failed instance, the participants were asked whether they had made an error.
每次失敗後，受試者會被問及他們是否犯了錯。

According to the study, younger participants were correct in acknowledging when they had erred 75% of the time.
研究發現，75%的情況下年輕的參與者準確地意識到自己犯了錯。

The older test-takers were correct 63% of the time when asked whether they had erred.
當被問及是否犯了錯時，年齡較大的受試者的回答在63%的情況下是正確的。

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.
這意味着在超過1/3的情況下，年齡較大的參與者沒有意識到自己犯了錯誤。而且，老年人更可能堅持認爲自己沒有犯錯。
