So they had people play this game while they were being scanned in an fMRI, and two conditions: in some trials, they're told you're playing another person who's playing right now and we're going to match up your behavior at the end and pay you if you win.
所以他们让人们玩这个游戏的同时 也在用磁共振扫描他们的大脑 并且发现两种情况：在一些试验中 人们被告知正在和其他的人一起玩这个游戏 并且最后会根据你的行为 判定你是否胜出并给与奖励
