Optimists and realists: heterogeneous priors in rats performing hidden state inference
Andrew Mah,Christine Constantinople · COSYNE 2022
A principle of modern decision theories is reference dependence, in which the subjective value of a reward is computed relative to an internal reference point that is thought to reflect expectations. Previous work often assumes that reference points are retrospective, deriving directly from past experiences. We used behavioral modeling to show that, instead, rats infer underlying task states in order to switch between multiple reference points. We designed a behavioral paradigm with partially observable states – uncued blocks of trials offering only small rewards (low blocks) or large rewards
