The performance of monkey participants in the confidence-rating density-discrimination task of Experiment 1B. A. Monkey Murph’s use of the two risk choices. The filled and open circles show his use of the high-risk choice and low-risk choice, respectively, for stimuli at different density levels. B. Monkey Lou’s use of the two risk choices. C. Monkey Murph’s percentage of correct dense–sparse responses at each density level when these responses were followed by high-risk choices (filled circles) or low-risk choices (open circles). D. Monkey Lou’s percentage of correct dense–sparse responses at each density level when these responses were followed by high-risk choices (filled circles) or low-risk choices (open circles).
