Reading a nasty word in a second language may not pack the punch it would in your native tongue, thanks to an unconscious brain quirk that tamps down potentially disturbing emotions, a new study finds.
When reading negative words such as “failure” in their non-native language, bilingual Chinese-English speakers did not show the same brain response as seen when they read neutral words such as “aim.” The finding suggests that the brain can process the meaning of words in the unconscious, while “withholding” information from our conscious minds.
“We think we’ve identified, for the first time, the mechanism by which emotion controls fundamental thought processes outside consciousness,” study researcher Wu Yanjin, a psychologist at Bangor University in the UK, said in a statement.

用第二語言唸一個不雅字眼,威力或許不如用母語讀來得大,這是拜大腦一種無意識的奇怪特性之賜,新研究發現,這種特性會壓制可能令人不安的情緒。
說中英雙語的人以非母語語言唸像「失敗」這類負面字眼時,不會出現讀到「目的」等這類中性字眼時同樣的大腦反應,這項發現表示,大腦可在無意識下處理字句意義,「壓制」訊息不讓我們有意識的心智察知。
「我們認為,我們首次找出了情緒在人的意識之外控制基本思維過程的機制」,進行這項研究的英國班戈大學心理學家吳嚴金在聲明中說。
研究人員在《神經科學期刊》發表的報告中說,目前還不清楚大腦為何抑制對這些字眼的反應。

Tangbao are one of the most internationally renowned delicacies, that win the hearts of both locals and tourists. Their charm lies in the paper-thin flour wrapper that needs to be folded evenly almost 20 times. Folding a tangbao requires skill to deal with a bulging filling and a thin wrapper. Tangbao are served in a bamboo steamer in which they are steamed, not only adding to the visual appearance, but ensuring they do not get cold before reaching the table. The best way to enjoy a tangbao is to dip it in a mixture of vinegar and soy sauce with
The Bank of Japan (BoJ) announced a seismic change in direction on March 19, hiking interest rates for the first time in 17 years. The move represents an unwinding of an ultra-loose — and maverick -- policy aimed at putting Japan’s “lost decades” of stagnation and deflation behind it. The last time the BoJ raised interest rates was in 2007, but its war against deflation began in earnest in 2013 under then-prime minister Shinzo Abe. “Abenomics” combined generous government spending and central bank monetary easing. The BoJ spent vast amounts on bonds and other assets to pump liquidity into the
Have you ever wished for an extra hour to prepare for exams or finish homework? In some countries, people actually adjust their clocks to gain or lose an hour, all for the sake of Daylight Saving Time (DST). Specifically, clocks are set forward by an hour in March and then set back in November. One of the primary reasons for implementing DST is to make better use of natural daylight so that people can reduce energy consumption. The concept originated with Benjamin Franklin in 1784 and became widely adopted during World War I. Today, this system is in place
For the first time, the US Federal Communications Commission (FCC) has fined a company for improper disposal of its defunct satellite. The satellite cable company Dish Network was fined US$150,000 because it failed to move an old satellite that was no longer in operation to a safe distance from others currently being used. The FCC had asked Dish Network to move one of its older satellites, EchoStar-7, 186 miles further from the Earth. However, the satellite had only advanced 76 miles before it ran out of fuel at the end of its operational life in 2022.
