Computer brain games may not offer the big mental boost many were hoping for, suggests new research, but brain scientists and brain-game experts don’t all agree on the findings.
The study, out this week in Nature, is the largest of its kind, say scientists from England’s Medical Research Council Cognition and Brain Sciences Unit and the Alzheimer’s Society, UK. They said in a Tuesday press briefing that brain-training games, used by millions, may not increase general brain power on other tasks or increase IQ "Participants did get better at games they practiced. The more they trained, the better they got. But there was still no translation to any general improvement in cognitive function," said lead author Adrian Owen, assistant director of Medical Research Council.
The online experiment was sponsored by the BBC and involved more than 11 000 people between the ages of 18 and 60. They were split into three groups, including two groups that played different brain-training games that are similar to commercially available games, and a control group that was asked to go online and find answers to questions about topics such as music. Participants trained for at least 10 minutes a day, three times a week, for up to six weeks, Owen said. All took standard cognitive assessment tests at the start and finish of the study. While players increased their skills the more they played a specific game, that improvement didn’t transfer to other activities or to a higher score on intelligence tests, said Owen and colleagues.
Duke psychiatrist and Alzheimer’s expert Murali Doraiswamy said it’s the best study done to date and a good reality check. "There was so much hype surrounding brain games," he said. But it’s not a death knell for gaming, Doraiswamy said. "I still think brain games offer tremendous potential for helping people with conditions such as ADHD and learning disabilities, but this study puts the burden of proof now on game manufacturers to show that they really offer meaningful benefits. "
Study shortcomings include the fact that it didn’t focus on the aging population, a group targeted by brain-game makers, experts said. And it did not look at benefits of more intense training, said Alvaro Fernandez, CEO and cofounder of Sharp Brains, a San Francisco market research firm that specializes in cognitive science. "This study shows random brain exercise doesn’t transfer, but it does not deny that transfer can work if a person engages in more intense and targeted brain-training," Fernandez said.
According to Adrian Owen, the function of brain-training games is that ______.
选项
A、they can make general brain powerful
B、they may offer the big mental boost
C、they can transfer to improvement in cognitive function
D、they have nothing to do with improving cognitive function
答案
D
解析
文章第二段倒数一、二句提出了欧文的观点“他们训练得越多,玩得就越好,但是它并不能转化为认知功能的改善”,故欧文认为智力游戏不能改善认知功能,[D]是原文意思的同义转述,所以为正确答案,同时排除[C]。[A]是根据第二段第二句设置的干扰项,且与原文意思相反,故排除。[B]是根据文章首句设置的干扰项,因为它不是艾德里安·欧文的观点,所以也排除。
