This research is meant to test the interaction between chess and the psychedelic experience. The questionnaire is divided in two sections, one is related to the effects of playing chess on the effects of the psychedelic experience while the other part collects information about the impact of the psychedelic experience on chess play.
Please fill this questionnaire only if you played at least a full game (ideally a bigger amount of games) after having consumed a psychedelic substance such as psilocybin, DMT, LSD, 2-CB, MDMA, among other substances known to alter consciousness in acute ways.
Take your time and think back on your experience playing during the psychedelic experience. Thank you for your participation.
