经历过灾难的人往往会出现一些精神问题，比如：常常不由自主地回想起当时的可怕场面。一项新的研究显示，家喻户晓的“俄罗斯方块”游戏或许能帮上忙!因为这种游戏的画面会与灾难画面竞争大脑资源，从而抑制创伤所带来的影响。看来，除了娱乐，“俄罗斯方块”没准儿日后真能派上心理治疗的用场呢! In a follow-up study to their original 2009 research, Oxford University scientists found that playing Tetris after a traumatic event may help prevent flashbacks, the intrusive and unwanted memories of trauma that are the hallmark of post-traumatic stress disorder. They also found that this protective effect may be unique to Tetris; when another computer game was tested, it made people’s flashbacks worse. In the first of two experiments, researchers had 60 adults (aged 18 to 60) with no history of mental health problems watch a 21-minute film containing traumatic content, like fatal traffic accidents and bloody scenes of human surgery. Such unsettling images—here, a stand-in for real trauma—can be hauntingenough to produce mild flashbacks after viewing. Thirty minutes after the film, participants wererandomly assigned to three 10-minute tasks: playing Tetris, playing another computer game called Pub Quiz, or just sitting quietly. During the 10-minute intervention, the researchers found that people in the Tetris group reported fewer flashbacks of images from the film than people in the Pub Quiz and do-nothing groups (there was no difference between the latter two). |
