I found myself struggling a bit to really wrap my mind around your phasic dopamine post, and the concrete examples in here helped me get a much clearer understanding. So thank you for sharing them!
Do you have a sense of how these very basic, low-level instances of reward-based learning (birds learning to sing, campers learning to avoid huge spiders, etc.) map to more complex behaviours, particularly in the context of human social interaction? For instance, would it be reasonable to associate psychological "parts", to borrow from Internal Family Systems terminology, with spaghetti towers of submodules that each have their own reward signal (or perhaps some of them might share particular types of reward signals)?
