I was recently told about a Science paper that suggests the old model of association of cause with effect is incorrect. In this model, cue comes, reward occurs, cue comes again, prediction of reward occurs; over time, calibration between prediction & presence of reward is refined.
This new model proposes that when a reward occurs, animals look back and scan for events that were salient enough to act as causes for a future reward. Mesolimbic DA mediates this process and the authors hypothesise that the OFC provides the relevant cue-reward information.
I was fascinated to read this finding. However, I have no relevant expertise to judge the animal models used (other than recognising the paper was published in Science so they're probably very convincing). For those in the field, have the experiments provided robust evidence to support the new model? To speculate, say the prior in the old model among neuroscientists was 0.7, what's the posterior since this paper? I understand no replications have been published but I'd appreciate if someone could point me to a preprint if one exists.
Thanks for your time.
