Brain Represses Bad Words for Bilingual Readers


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 devised this experiment to unravel the unconscious interactions between the processing of emotional content and access to the native language system. We think we've identified, for the first time, the mechanism by which emotion controls fundamental thought processes outside consciousness," study researcher Yanjing Wu, a psychologist at Bangor University in the United Kingdom, said in a statement. "Perhaps this is a process that resembles the mental repression mechanism that people have theorized about but never previously located."

Translating negativity

Bilingual people typically respond less emotionally to words in their second language. For example, swear words in a foreign tongue don't usually feel as shocking; likewise, some research has found that people are more comfortable talking about embarrassing topics in a second language.

To unravel the emotions of language, Wu and his colleague Guillaume Thierry, also of Bangor University, recruited 15 native English speakers, 15 native Chinese speakers, and 15 native Chinese speakers who were also fluent in English (all had first learned English around age 12). They set up an experiment in which these volunteers saw word pairs on a screen. One of the words was always neutral, while the other could be neutral, positive or negative. In addition, each word was two syllables in Chinese, with the first syllable of each word always sounding the same.

For example, the positive word "honesty" was paired with the neutral word "program." In Chinese, honesty translates to "chengshi" and program to "chengxu." Negative words included failure, war, discomfort and unfortunate.

The participants were asked to push a button if the words were linked in meaning. (In some pairs, they were.) Meanwhile, the scientists used electrodes on the scalp to measure the electrical response in the brain to reading these pairs of words.

Self-protection

The findings revealed that although they weren't aware of it, the bilingual participants' brains were translating the positive and neutral words into Chinese as they read them in English. But surprisingly, .. ( more at http://www.livescience.com/20172-brain-represses-negative-emotions.html )
