The Influence of Stimulants on Performance When Playing Chess

March 8, 2017

(Science Blog) – How do highly complex cognitive processes change when we take pharmacological substances? Is it possible to enhance these processes by using substances such as the CNS stimulant methylphenidate or the wakefulness promoter modafinil, or do these actually undermine creative thinking and the ability to concentrate? Researchers at the Department of Psychiatry and Psychotherapy at the Mainz University Medical Center have recently looked into these and other questions in a randomized placebo-controlled double-blind study. The conclusion they came to was surprising: they found that high-performance tournament chess players can actually enhance the highly complex cognitive functions they require by taking these substances and thus win more chess matches–unless they are under time pressure.
