Learning occurs when an outcome differs from expectations, generating a reward prediction error signal (RPE). The RPE signal has been hypothesized to simultaneously embody the valence of an outcome (better or worse than expected) and its surprise (how far from expectations). Nonetheless, growing evidence suggests that separate representations of the two RPE components exist in the human brain. In this work, we used an fMRI meta‐analysis to argue for a sequential and distributed encoding of different components of the RPE signal, with potentially distinct functional roles.
