The experiment is to give one of 39 participants one of the stimulant methylphenidate, modafinil, caffeine, placebo. After taking the stimulant, the subject performed 20 times of 15-minute bout against the computer, and then took the test of neuropsychology. In the experiment, a total of 3059 chess matches were made.

Analyzing the data obtained from the game, players who ingested either methylphenidate, modafinil or caffeine tended to think longer than their players who took placebo, and sometimes overtime It was confirmed that it was. In other words, the players were thinking slower to contemplate than playing regularly.


In addition, players who ingested methylphenidate or modafinil recorded a higher score than players who ingested placebo in 2876 games, which lost games due to overtime due to overtime from all games performed in the experiment. The research team integrated these results with neuropsychological tests and found that stimulants are unlikely to improve the quality of thinking and decision-making ability in time, but in decision making In the case that it can take a long time, stimulants are considered to enhance performance ".

Dr. Lieb says that whether a stimulant strengthens its ability in chess requires further experimentation, "We need strong doping control in the chess competition tournament."
