Speaking two languages can actually help offset some effects of aging on the brain, a new study has found.
一项新研究发现,说两种语言实际上能够帮助消除衰老对大脑的影响。
Researchers tested how long it took participants to switch from one cognitive task to another, something that’s known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky. As he spoke to ABCNews.com from his cell phone, he said he was also in a grocery store choosing between gala and granny smith apples — a perfect example of switching between cognitive tasks in everyday life.
研究者测试了参与者们从一个认知活动转换到另一个需要的时间。主管研究员布莱恩·古尔德是肯塔基大学的神经学家,他表示老年人转换任务需要的时间更长。当他和ABCNews的记者在手机上说话时,他说自己正在一家蔬果店考虑到底是要买小富士苹果还是美国青苹果,这就日常生活中认知活动最典型的例子。
“It has big implications these days because our population is aging more and more,” Gold said. “Seniors are living longer, and that’s a good thing, but it’s only a good thing to the extent that their brains are healthy.”
“这个研究有重大的意义,因为我们的人口现在越来越老龄化了,”古尔德说。“老年人活的时间更长了,这是件好事,但是前提是他们的大脑要保持健康。”
