(A) An agent can use multiple sources of information when making decisions, for instance, which book to read next. In that example, they can use item-based information, such as the genre of the book (green), or social-based information, such as whether it has been recommended by a well-known critic (yellow). Feedback (Was the critic right? Was that specific genre enjoyable?) can drive learning about both sources of information. (B) The way the decision is framed and presented could make one source of information the primary source, and the other the secondary or supporting source. Results from Rybicki et al., 2022 suggest that the primacy of the source of information, and not its type (social/item-based), determines its dependency on dopaminergic learning mechanisms.
