Comparison of agents’ performance.
Performance achieved by different agent types in the original (A) and reduced (B) tasks, with parameter values optimised to maximise the fraction of trials rewarded. For the reward as cue agent, performance is shown for a fixed strategy of choosing action A (B) following reward in state a (b) and action B (A) following non-reward in state a (b). SEM error bars shown in red. Significant differences indicated by *: 5 < 0.05, ** P < 10−5.
