Monkeys' choice preference between CSs associated with different reward variances. The monkey made a choice between two CSs among the four well-learned CSs, indicating different reward variances (Fig. 8). A, Choice between two reward variance CSs. B, Choice percentage of a single reward variance CS versus all the other reward variance CSs. Data are compiled from a dataset of 4672 choice trials performed by Monkeys H and P.
