HLC exploration task. a The HLC exploration task. In this task, monkeys had to choose between R+ and R− cues, which were randomly generated in each learning session. If they chose the R+ cue they could obtain a reward and if they chose R− cue they would not obtain reward. b RTs to the cost cues in the high-cost and low-cost trials. The monkeys showed faster RTs to the low-cost cue (**P< 0.01; two-tailed paired t test). Black circles and error bars indicate mean and SEM. c RTs to the reward cues in the high-cost and low-cost trials. Monkey S showed faster RTs to the reward cues in the high-cost condition
