*The drugs are methylphenidate, which is most commonly marketed as Ritalin (by Novartis), and modafinil, which is sold as Alertec, Modavigil and Provigil. The study also measured the effects of caffeine and found, not surprisingly, that it also had an ameliorative impact.*

*the study found modafinil improved the players’ performances by an average of 15 percent, methylphenidate by 13 percent, and caffeine by around 9 percent.*

*The new study, which was conducted by 13 professors and researchers from several German universities and the University of Stockholm, is titled, “Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomized controlled trial.”*
