They were compared to more than 2,700 people who didn’t play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given IQ test before and after the experiment. Researchers said the people who did the brain training didn’t do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.
研究人员将这些参与者与2700多名没有玩任何益智游戏，但用相同时间上网并参与普通知识问答的人作对比。在实验前后，所有参与者均接受了智商测试。研究人员说，在六个星期后的智商测试中，玩益智游戏的人并没有比那些单纯上网的人表现得更为出色。在测试的某些环节，单纯上网的人获得的分数比玩游戏的人还要高。
