To win at rock, paper, scissors try closing your eyes. It could help you to control an unconscious urge to imitate your opponent.
Richard Cook at University College London and colleagues asked 45 adults to play rounds of the game with either one or both players blindfolded.
There were significantly more draws when one player was sighted, but when someone did win; it was more often a blindfolded player than a sighted one.
Cook found that sighted players often gestured around 200 milliseconds after the blindfolded opponent, and suggests this reflects an automatic urge to imitate others.
Peter Enticott, a psychologist at Alfred Hospital in Melbourne, Australia, says this type of imitation is "beyond our control" and shows we are "rapidly influenced" by those around us.


据《新科学家》20日刊登的一项研究称，要想在"剪刀石头布"游戏中取胜，不妨尝试把眼睛闭上。闭眼或许有助于控制人在不自觉中模仿他人动作的行为。
英国伦敦大学的查理德•库克与他的同事们让45个成年人玩几盘"剪刀石头布"游戏，并且蒙上两位玩家中其中一位的眼睛，或者两位玩家的眼睛都被蒙上。

当一人被蒙上眼睛时，平局明显增多，但是被蒙上眼睛的人比可以看见的人更容易取胜。

库克发现可以看见的玩家往往比蒙上眼睛的玩家晚200毫秒出动作，这表明人们在玩此游戏的过程中会无意识模仿对方的动作。

澳洲墨尔本市阿尔弗雷德医院的心理学专家皮特•艾迪克特说，这种模仿是"无法控制"的，这也说明我们能够很快被周围的人影响。
