'It seems that it allows them to perform at a higher level.'
他说:“这项研究表明,对于健康的老年人来说,即使他们的记忆力略有减退,他们也能轻易调动平时很少刺激到的大脑区域。这似乎能让他们的表现更佳。”
The study used functional magnetic resonance imaging (fMRI) -- a noninvasive technique that indirectly measures changes in brain activity -- to scan the brains of 20 younger adults (25 years old, on average), and 22 older adults (around 70 years old) while the participants viewed pictures of consumer products with star ratings indicating their value, similar to online shopping sites like Amazon.com.
有20位年轻人(平均年龄25岁)和22位老年人(70岁左右)参与了该研究。他们需要浏览一些标有价格星级的商品图片——类似于浏览亚马逊(Amazon.com)等购物网站,与此同时,研究者用功能性磁共振成像技术(fMRI)扫描他们的大脑。
Participants were asked to 'keep shopping' by navigating from one screen to the next while trying to remember the value for each consumer product they encountered.
参与者的任务是在一张张图片被展示时“不停地购买”,同时还要记住每件商品的价格。
They then had to select the better of two competing products, such as two different sweaters, based on which was a better value.
之后,参与者要在两个竞争商品中选出较好的一个,比如在两件毛衣中选出较有价格优势的那件。
