Time to get some of those iridescent Chris Moneymaker glasses. According to a new study published in the journal Current Biology your eyes could give away not just whether you have a good hand or not, but the actual numbers of the cards in your hand. Researchers asked study participants to name a string of random numbers, and by measuring horizontal and vertical eyes position the researchers were able to reliably predict the next number before it was spoken. Your bluff just might be toast.
The researchers noticed a distinct trend when participants were conjuring their random number strings: A leftward shift accompanied by a downward shift consistently indicated that the next number would be of lesser value than the one before. Likewise, an upward-right positioning suggested a larger number than the previous one. The degree of the movement corresponded to the size of shift in value.
Why does this happen? According to the University of Melbourne researcher who authored the study, our brains tend to code numbers spatially along a horizontal plane; smaller numbers fall to the left, larger ones to the right – similar to the way numbers would look if you started writing them in sequence on a piece of paper (1,2,3,4,5,6, etc.).
But don't worry too much about your poker face. The researchers were only able to measure eye position during the 500-millisecond (that's a half-second) interval between the subject's thinking of the number and his stating it aloud, a difficult feat for your – or your opponents' – naked eyes. But it could help researchers gain better insight into how our mind organizes fundamental concepts and how things we often consider abstract, like numbers, are connected to spatial reasoning.
Seems kind of hard to imagine that you can tell what the card is from eye movement. when i play poker, sometimes i dont move my eyes at all or sometimes im moving hema alot. i dont think it means much.
And for Arabic speaker/writers, do the eyes shift the opposite direction?
Actually, as I learned when I lived in Iran, while they write (and read) words from right to left, they write (and read) numbers from left to right.
Now I know which direction to look in when I play poker. :P
OK gonna rig up a 1200 fps camrah to be controlled by google android and somehow sneak it into a high stakes poker mach.
I get what GTO is talking about. I thought the author's 2nd paragraph is obviously sarcastic and slightly demeaning to India which is clearly seen in the sentence: "Neither the laser nor the kill vehicle actually exists yet, but be forewarned: India will put a dent in your space capabilities at a time and place as yet undetermined.
