Dependence of the animal's choice on the magnitudes of actual and fictive rewards.
(a) Trials were divided into nine groups according to the combination of actual and fictive reward magnitudes in the previous trial. The proportion of stay trials is indicated in gray scale. Mean, the proportion of stay trials was averaged across animals. (b) Trials were divided into three groups according to the magnitude of actual (left) or fictive (right) reward in the previous trial. Blue circles, proportions of stay trials; red circles, proportions of switch trials. Mean, the proportions of stay and switch trials were averaged across animals (mean ± SEM).
