Identifying situations in which exploration could be beneficial, and learning from such choices, is critical for survival in complex environments. Nonetheless, it is still unclear how animals adapt their choice strategies depending on the potential benefits of exploration and what the neural underpinning of this ability is. We thus adapted a 2-option forced-choice task in which 3 rhesus macaques made choices while the information and the feedback they received was being manipulated: (i) feedback was given about either just the chosen option or both the chosen and unchosen counterfactual option
