Rules of games - Poker hands part 1
"POKER face" like is titled a song of Lady Gaga it is the expressionless gaze that gives nothing away.
Impossible to discover any feeling or thoughts. To win at poker, the face must be mastered, and master it is what the best players try their best to do.
According to a study recently published in Psychological Science of Stanford University, even people with the best poker faces give the game away. They do so, however, not with their heads but with their hands.
Mr Slepian and his collegue made their discovery when they showed 78 undergraduate volunteers video clips of players placing bets at the 2009 World Series of Poker.
(Bets in poker are placed by pushing chips into the middle of the table.) The clips were 1.6 seconds long, on average, and featured different parts of the players’ anatomies. Some showed everything visible from the table up: chest, arms and head. Some showed just the face. And some showed only the arms and hands. Each volunteer watched only one of the three types of video, but was shown several examples.
After each viewing, volunteers were asked to rate the quality of the player’s hand on a seven-point scale. Then, when they had finished watching all the clips, they were asked to rate their own experience with poker on a similar scale.
Mr Slepian found that when shown just that player’s face students were poor at judging the quality of a player’s hand. But he noticed a negative correlation of 0.07 out of 1 (1 is the perfect correlation). Actually this is not high, not at all, just it meant there was a statistically significant tendency that the better a volunteer believed the hand to be, the worse it actually was.
When a player’s whole posture was considered, this misapprehension went away: if a volunteer could see everything about a player from the table up there was no correlation between his judgments of a hand’s value and its actual value. When a volunteer could see only arms and hands, however, Mr Slepian found a positive correlation, of 0.07, between reality and his guesses.
To confirm his discovery, Mr Slepian re-ran the experiment with a different group of clips and incredibily the results were the same. Wow! Students, even those who were poker novices, could judge the quality of a professional poker player’s cards from the behaviour of his hands. Now the one million dollar question it is: "how"?
