The researchers got people to play against the computer in "rock-scissors-paper". This allowed them to find out the main psychological mistake that causes people to give opponents. About the discovery reported in the journal Scientific Reports, and briefly about it tells Gizmodo.
From an objective point of view of "rock-scissors-paper" — a game based on pure chance. If you forget about the psychological aspects, the best tactic is a random selection of each option — with the same frequency.
However, emotions cause people to adjust their strategy based on the results of the previous round. Researchers from the University of Sussex (UK) and Ryerson University (Canada) made the volunteers play against the computer, choosing the codes at random. It turned out that people constantly fall into a trap: when they win, they continue to show the same figure. In case of loss, people often switch from stone to scissors, in case of a tie — from stone to paper. Most people show the stone.
The researchers note that "the data obtained indicate the strategic vulnerability of the player after a negative experience". In other words, people tend to revise their behaviour in case of loss — even at the expense of yourself.
In 2013, researchers from the University of Tokyo have designed a robot that uses computer vision technology that wins in a game of "rock-scissors-paper" one hundred percent of the cases. In humans, the formation shape ("stone", "scissors" or "paper") out of approximately 60 milliseconds. About 35-th millisecond of the action the robot performs OCR, and adds a "response" figure. It takes about 20 milliseconds, meaning it completes a turn earlier.
