I wonder how the following behavioral patterns fit into Shard Theory
Many mammalian species have strong default aversion to young of their own species. They (including females) deliberately avoid contact with the young and can even be infanticidal. Physiological events associated with pregnancy (mostly hormones) rewires the mother’s brain such that when she gives birth, she immediately takes care of the young, grooms them etc., something she has never done before. Do you think this can be explained by the rewiring of her reward circuit such that she finds simple actions associated with the pups highly rewarding and then bootstraps to learning complex behaviors from that?
Salt-starved rats develop an appetite for salt and are drawn to stimuli predictive of extremely salty water, even though on all previous occasions they found it extremely aversive, which caused them to develop conditioned fear response to the cue predictive of salty water. (see Steve’s post on this experiment)

I’ve been wondering about the latter for a while. These two results are less strongly predicted by shard theoretic reasoning than by “hardcoded” hypotheses. Pure-RL+SL shard theory loses points on these two observations, and points to other mechanisms IMO (or I’m missing some implications of pure-RL+SL shard theory).
