试题详情及答案解析
HOW many of you have used rock, paper, scissors (RPS) as a “fair” way to settle something? If you think it is a game of chance, think again, according to scientists.
RPS is a game as popular in the East as it is in the West. The rules are the same: Two players make one of the three hand signs. To decide the winner, rock breaks scissors, scissors cut paper, and paper covers rock.
Many of us play with no game plan in mind. But researchers have worked out several winning patterns. The World Rock Paper Scissors Society holds tournaments (联赛) in Toronto, Canada. According to their data, players choose rock (35.4 percent) and paper (35 percent) more than scissors (29.6 percent).
If your opponent is a man or an angry person, it’s quite possible they will start the game with rock, researchers have found. If your opponent is a woman or a beginner, you should expect them to start with scissors.
Earlier this year, Chinese scientists asked 360 students to compete in a RPS tournament at Zhejiang University. Scientists found that winners tend to choose the same action they won with, while the loser tends to change to the next action in the order of rock, scissors, paper.This is called the “win-stay lose-change” strategy(策略). Humans use this strategy in many competitive situations.
Expert RPS players have many other techniques. Monica Martinez, 2008 winner of the World RPS Tournament, said that she read faces.“I didn’t worry about what I was going to do, I just did what I thought they were going to do,” she told The Telegraph. If your friends are similar experts, learn from Jonathan Monaco, winner of the 2009 USA RPS Tournament. He wears dark sunglasses to cover his expressions during the game.
Remember, the strategy for playing RPS depends on how skilled your opponent is. But if you’re looking for a quick, simple winning rule for a match, choose paper. Scissors is the least popular choice, and men favor rock. Both are reasons to choose paper.
