Unpleasant memories can arise and disappear without a trace. In some cases, the memories are so strong that prevent a person to live. Then talk about the development of post-traumatic stress disorder. Scientists from Oxford University have found a way to prevent the development of this deviation is a simple computer game.
The volunteers were asked to watch a movie with scenes of accidents, it was most unpleasant emotions, which persisted during the day. After 24 hours of the volunteers once again watched the movie, the others did the same, and then went to play Tetris, says Zee News.
Arcade game helped the volunteers to forget unpleasant memories. Thoughts about the accidents occurred in "playing" the group much less. Scientists say, to remove unpleasant memories required and a computer game, and reactivation of emotions.
