Here, Chang et al show that blocking dopamine transients prevents learning about unexpected rewards. Learning was prevented whether it was driven by the addition of reward or by a valueless change in the flavor of the expected reward. This result is contrary to the proposal that dopamine transients act only as cached value prediction errors.
