Intertemporal choice of participants in the high-uncertainty and low-uncertainty groups in Study 2. Participants who felt high uncertainty (vs. low uncertainty) chose the smaller-sooner gain option more times. The intertemporal choice is the total number of times that participants choose the smaller-sooner gain option. Box boundaries represent lower and upper quartiles, interior lines within boxes represent median, whiskers for data range (minimum to max), and + represent mean value. ** p < 0.01.
