Fig. 1. Task Design. a) Schematic of the transition structure with arrows displaying deterministic transitions; if a participant chose the dark blue or the orange spaceship, they would always transition to the red planet. b) At the planets, participants received rewards in the form of space treasure ranging between 0 and 9 pieces according to the drifting reward rate per planet. c) At the start of the trial, participants saw the stake amplifier, which either showed "1x" for low-stake trials or "5x" for high-stake trials. Next, they saw a pair of spaceships and chose one, after which they transitioned to either the red or the purple planet, where they had the opportunity to win pieces of treasure. During low-stake trials, pieces of treasure were displayed in blue with a red "1" on every piece, and participants received points equal to the number of treasure pieces shown. d) During high-stake trials, the blue treasure was displayed first and then, after a delay, turned into gold treasure
