Experimental Task Design. On each trial, we presented participants with two cues that were predictive of points (cold colors) and/or information (warm colors)-both of which were critical for receiving monetary reward. We presented these cues in two distinct formats. During free-choice trials, the cues were mixed, thus allowing participants to freely express their preference between points and information. On forced-choice trials, both cues were predictive of points or information, thus forcing the participant to choose the given option. (Note that the words “information” and “points” were not presented to the participants during the task; they are shown here for illustrative purposes).
